Prescription, Documentation, Drug Administration Rules & Safety Precautions

Why this lesson matters: A medicine can be pharmacologically correct and still harm a patient when it is prescribed for the wrong person, written unclearly, calculated incorrectly, prepared in the wrong concentration, given by the wrong route, administered without a safety check or left undocumented. Emergency care demands speed, but speed must be organised, traceable and safe.

Learning outcomes

By the end of this lesson, the emergency medicine student should be able to:

Define prescription, medication order, dispensing, administration, transcribing, documentation, medication error and adverse drug reaction.
Identify the essential legal and clinical elements of a complete prescription and a safe verbal or telephone order.
Explain the responsibilities of prescribers, pharmacists, nurses, EMTs, students, patients and caregivers at each stage of medication use.
Apply the expanded rights of medication administration to oral, parenteral, inhaled, topical and emergency medicines.
Perform a structured pre-administration assessment, calculation, preparation, administration, monitoring and documentation sequence.
Recognise high-alert medicines, look-alike/sound-alike products, unsafe abbreviations, decimal errors and common system hazards.
Describe the requirements for controlled medicines, storage, cold chain, stock checks, wastage, witnessing and accountability.
Respond safely to omitted doses, wrong doses, wrong routes, near misses, adverse drug reactions and suspected poisoning.
Communicate medication information during handover, referral, admission, transfer and discharge.

1. Key definitions

Term	Meaning	Why it matters in an emergency
Prescription	A lawful instruction from an authorised prescriber for a medicine to be supplied and used by a named patient.	It links a clinical decision to a specific patient, product, dose, route, schedule and prescriber.
Medication order	An instruction to administer a medicine in a facility, whether written, electronic, protocol-based or an authorised verbal order.	It must be complete, attributable and clinically checked before administration.
Transcribing	Copying or transferring a medicine order from one approved record to another.	Transcription errors can change the patient, medicine, dose, route or timing.
Dispensing	Selecting, preparing, labelling and supplying a medicine for a patient.	The dispenser is an additional safety barrier, not merely a supplier.
Administration	Giving a medicine to a patient by the prescribed or authorised route.	The person administering must assess, check, give, monitor and document.
Documentation	A contemporaneous record of assessment, order, preparation, administration, response, refusal, omission or error.	It supports continuity, accountability, legal review and learning.
Medication error	A preventable event that may cause or lead to inappropriate medication use or patient harm while the medicine is controlled by the health worker, patient or consumer.	A near miss is still valuable safety information even when no injury occurs.
Adverse drug reaction	A harmful and unintended response to a medicine used at normal doses.	It may require immediate treatment, a documented allergy alert and pharmacovigilance reporting.
High-alert medicine	A medicine that carries a heightened risk of serious harm when used in error.	Requires stronger safeguards such as independent double-checks and monitoring.
Medication reconciliation	Creating the most accurate list of medicines a patient uses and comparing it with new orders.	It prevents omissions, duplications, contraindications and unintended interactions during transitions.

2. The medication-use pathway

Safe medication practice is a chain. A weakness at one point can reach the patient unless another person or system catches it.

Medication chain: Assess → Prescribe/authorise → Transcribe → Dispense/select → Prepare → Identify → Administer → Monitor → Document → Review → Handover/report.

Stage	Main safety question	Typical failure
Assessment	Does this patient need a medicine, and what problem is being treated?	Treating a symptom without recognising shock, hypoxia, hypoglycaemia or poisoning.
Prescribing/authorisation	Is the medicine, dose, route and timing appropriate and lawful?	Incomplete, illegible, ambiguous or unauthorised order.
Transcribing	Was the order transferred accurately?	Wrong decimal, wrong frequency or copying into the wrong chart.
Dispensing/selection	Is the correct product, strength, dosage form and quantity selected?	Look-alike packaging, wrong concentration or expired medicine.
Preparation	Was it prepared with the correct dilution, equipment and infection-control technique?	Unlabelled syringe, incompatible diluent or contamination.
Administration	Are the patient, medicine, route, dose and time correct?	Wrong patient, route, rate or omitted allergy check.
Monitoring	Did the intended effect occur, and has harm developed?	No reassessment after analgesia, sedation, insulin, bronchodilator or antihypertensive.
Documentation and review	Can another clinician see exactly what happened and what is due next?	Unsigned dose, undocumented refusal or no handover about a critical medicine.

3. Legal and professional foundations

In Uganda, medicine supply and control operate within the National Drug Policy and Authority framework, together with professional-council rules, the National Formulary, Ministry of Health guidance and facility policies. The National Drug Authority regulates medicine quality, registration, supply chains, licensing and safety monitoring. A practitioner must use the current law and local policy in force; teaching examples do not replace an authorised prescription or protocol.

Core legal principles

Authorised prescriber: the person issuing an order must be legally authorised for that medicine and setting.
Professional scope: the person administering must be trained, competent, supervised where required and authorised by law, protocol and employer.
Product legality: use a registered or otherwise lawfully authorised product obtained through an approved supply chain.
Patient specificity: a prescription identifies a named patient; do not transfer another patient’s prescription or medicine without lawful review.
Traceability: records must show who prescribed, supplied, prepared, administered, witnessed, refused, omitted or wasted the medicine.
Controlled-medicine accountability: restricted medicines require additional storage, registers, stock reconciliation, witnessing and disposal controls.
Confidentiality: medication histories and errors are shared only for care, safety, lawful reporting or authorised quality improvement.
Duty to clarify: an unsafe, incomplete or ambiguous order must be held and clarified, even when the prescriber appears senior.
Duty to report: suspected adverse reactions, medication errors, diversion and unsafe products must follow facility and national reporting channels.

Important: A verbal instruction, emergency protocol or standing order is not a licence to improvise. It must fall within the approved setting, medicine, indication, dose, route and practitioner scope. If it does not, escalate before administration.

Ethical principles applied to medication use

Principle	Medication example
Beneficence	Select and give treatment that is reasonably expected to benefit the patient.
Non-maleficence	Prevent avoidable harm from wrong medicine, wrong route, excessive dose or poor monitoring.
Respect for autonomy	Explain treatment, respect a competent refusal and document the discussion.
Justice	Use essential medicines fairly and avoid discrimination or diversion of scarce supplies.
Veracity	Communicate honestly about an error, adverse reaction, omission or uncertainty.
Confidentiality	Protect prescriptions, medication histories and substance-use information.
Accountability	Accept responsibility for one’s own assessment, administration, documentation and escalation.

4. Components of a complete prescription

A prescription should be clear enough that a competent dispenser and administrator do not need to guess. Requirements differ by product and setting, but an emergency prescription should contain the following minimum information.

Prescription element	What to include	Safety purpose
Patient identifiers	Full name plus a second identifier such as age/date of birth, hospital number or address according to policy.	Prevents wrong-patient medication.
Date and time	Date issued and time when urgency or repeat timing matters.	Shows validity and supports time-critical administration.
Medicine name	Prefer the approved generic name; include brand only when clinically necessary.	Reduces duplication and brand confusion.
Strength and concentration	For example mg per tablet, mg/mL or units/mL.	Prevents selecting the wrong concentration.
Dosage form	Tablet, capsule, solution, suspension, inhalation, injection, cream, suppository or other form.	Prevents formulation and route errors.
Dose	Exact amount per administration, with units written clearly.	Prevents missing zeros, wrong units and dose multiplication.
Route	Oral, IV, IM, IO, SC, inhaled, buccal, sublingual, rectal, topical or another authorised route.	Route can change onset, bioavailability and toxicity.
Frequency/interval	How often, minimum interval and maximum number or dose when relevant.	Prevents early repeat dosing or accidental overdose.
Duration or quantity	Number of doses, days or total quantity, particularly for discharge prescriptions.	Prevents indefinite or excessive supply.
Indication and special instructions	Reason, dilution, rate, relation to food, monitoring or “stat/once only” instruction.	Helps the administrator interpret the order safely.
Prescriber identification	Name, signature/electronic identity, professional designation and contact/registration details as required.	Confirms authority and permits clarification.

Before accepting an order, ask: Who is the patient? What is the clinical indication? What exact medicine and strength? How much? By which route? How fast? How often? For how long? What monitoring is required? Who authorised it?

5. Prescription-writing rules

Write for clarity, not convenience

Use generic names where possible and write the complete medicine name.
Write metric units in full when confusion is possible; use mg, micrograms, mL and units clearly.
Use a leading zero for doses less than one unit: 0.5 mg, never .5 mg.
Do not use a trailing zero: write 5 mg, never 5.0 mg.
Write the dose, concentration and volume separately when an injection is involved.
State “once only,” “stat,” “PRN,” minimum interval and maximum dose clearly; do not rely on a vague “as required.”
Use an approved route and frequency; explain unusual abbreviations in words.
Indicate whether a dose is a loading dose, maintenance dose, infusion, bolus, titration or repeat dose.
For paediatric or weight-based doses, record weight, dose per kg and maximum dose where the protocol requires it.
For infusions, state the total drug amount, final volume, diluent, concentration, rate and duration.
Cross out and rewrite an error according to policy; never erase, overwrite or obscure a clinical record.

Abbreviations and symbols that create risk

Avoid	Why unsafe	Write instead
U or u	May be read as zero or another number.	units
IU	May be misread as IV or 10.	international units
µg or mcg when handwriting is unclear	May be confused with mg.	micrograms
QD, qd, QOD, qod	Daily or every other day may be misread.	daily; every other day
OD, BD, TDS, QDS in ambiguous contexts	May be misinterpreted across teams or records.	once, twice, three times or four times daily.
MS, MSO4, MgSO4 without context	Morphine, magnesium sulphate and similar abbreviations can be confused.	Write the complete generic name.
“cc”	May be confused with units or misread.	mL
“.5 mg”	Decimal point can be missed.	0.5 mg
“5.0 mg”	Trailing zero can be read as 50 mg.	5 mg
“amp” or “vial” as the dose	Container size varies.	State the actual amount in mg, micrograms, units or mL.
“PRN” alone	Does not state indication, minimum interval or maximum.	As required for [indication], every [interval], maximum [dose].

6. Verbal, telephone and emergency orders

Verbal orders are vulnerable to noise, interruptions, unfamiliar accents, similar drug names and memory errors. They should be limited to genuine urgency or circumstances permitted by facility policy.

Confirm necessity: ask whether a written or electronic order can be made immediately.
Identify the patient: state the patient’s full name and a second identifier.
Use a closed-loop exchange: the receiver writes the order and reads it back word for word.
Spell similar names: especially look-alike/sound-alike medicines.
Repeat all critical details: medicine, strength, dose, concentration, route, rate, frequency, indication and maximum.
Confirm allergies and contraindications: communicate relevant findings before administration.
Record the order immediately: include date, time, prescriber, receiver and the reason a verbal order was needed.
Obtain authentication: the authorised prescriber signs or electronically confirms within the timeframe required by policy.
Escalate uncertainty: “I am not confident I heard that safely; please repeat and spell the medicine.”

Closed-loop example:
Prescriber: “Give morphine.”
EMT: “For which patient and what exact dose, concentration, route and repeat interval?”
Prescriber: “Patient Amina Nakato, morphine 5 mg IV slowly once, reassess respiratory rate and pain before any repeat.”
EMT: “I read back: Amina Nakato, morphine 5 mg IV slowly once, reassess respiratory rate and pain before repeat. Is that correct?”
Prescriber: “Correct.”
The order is then recorded and authenticated according to policy.

7. Transcribing and medication reconciliation

Transcribing is not a clerical copying exercise. Compare the original order with the medication administration record, drug chart, transfer form, electronic record and discharge prescription. A second person should independently check high-risk or unclear entries.

Medication reconciliation at transitions

Ask the patient, caregiver, previous facility and available records what medicines are actually being taken.
Record generic name, strength, form, route, dose, timing, last dose and adherence.
Include allergies, previous reactions, over-the-counter medicines, herbal products, alcohol and recreational substances when relevant.
Compare the best possible medication history with new orders.
Classify each difference as intentional or unintentional.
Clarify unexplained omissions, duplications, interactions and contraindications.
Communicate the reconciled list during handover, referral, admission, transfer and discharge.
Give the patient or caregiver an understandable list and explain changes.

Transition	Common medication risk	Safety action
Home to ambulance	Unknown last dose, allergies or herbal products.	Ask, photograph packages when lawful, record time and communicate to receiving team.
Ambulance to emergency department	Duplicate doses after handover.	State exactly what was given, concentration, route, time and response.
Emergency department to ward	Stat doses, infusions or withheld medicines not communicated.	Use structured handover and verify the next due dose.
Hospital to home	Patient misunderstands new, stopped or changed medicines.	Provide a reconciled list, teach-back and follow-up instructions.
Referral to another facility	Medicine and documentation unavailable during transport.	Send the prescription/order, administration record, allergies and last-dose times.

8. Documentation standards

Document as close to the time of care as possible. The record must be factual, legible, permanent, attributable and sufficiently complete for another clinician to continue care.

What to document for every administration

Date and exact time administered.
Patient identity and clinical indication.
Generic medicine name, strength/concentration, dose, volume, route and rate when relevant.
Source of authority: prescription, protocol, standing order or emergency verbal order.
Assessment before administration: allergies, relevant vital signs, level of consciousness, glucose, pain score, respiratory status or other medicine-specific checks.
Preparation details when important: dilution, diluent, infusion pump setting, batch/expiry or device.
Name/signature/electronic identity of the person administering and witness where required.
Patient response, reassessment findings and adverse effects.
Reason for omission, refusal, delay, partial dose or variation from the order.
Escalation, notification, treatment and reporting when an unexpected event occurs.

Use objective language

Weak entry	Better entry
“Patient okay after drug.”	“10:35 — salbutamol nebulisation completed as prescribed. RR 30 to 22/min, SpO₂ 88% to 94% on prescribed oxygen, wheeze reduced; no tremor or chest pain reported. Continue monitoring.”
“Dose not given.”	“14:00 — dose withheld because BP 82/48 mmHg and patient dizzy; prescriber notified at 14:05; new instruction documented.”
“Allergic.”	“Within 5 minutes of medicine, patient developed widespread urticaria, lip swelling and noisy breathing; medicine stopped, ABCDE support initiated and senior clinician called.”
“Doctor told me.”	“11:20 — verbal order received from Dr [name], read back and confirmed: [complete order]; written authentication pending per policy.”

Correcting a documentation error

Do not erase, delete, use correction fluid or conceal the original entry.
Draw a single line through the error so it remains readable.
Write the correct information nearby, then add date, time and signature/initials.
For electronic records, use the approved amendment or late-entry function.
Never alter a record to make an error appear not to have occurred.

9. Expanded rights of medication administration

The traditional five rights are a foundation, not the complete process. A safe administrator checks the patient, medicine, indication, dose, route, time, documentation, response, education and right to refuse. Use the version required by your facility and add clinical assessment rather than treating the list as a tick-box exercise.

Right/check	Practical action	Example of failure
Right patient	Use two identifiers; match wristband, chart, verbal confirmation and order.	Giving medication to the patient in the wrong bed.
Right medicine	Compare order and label three times; check generic name and formulation.	Selecting a similarly packaged medicine.
Right indication	Understand what problem the medicine is treating and whether it remains present.	Giving a PRN sedative for agitation caused by hypoxia without correcting the cause.
Right dose	Check strength, units, weight, maximum, dilution and independent calculation.	Confusing mg with mL or micrograms with milligrams.
Right route	Confirm the ordered route and whether the patient can safely receive it.	Giving oral medication to an unconscious patient.
Right time	Check due time, last dose, minimum interval and urgency.	Repeating an analgesic before the permitted interval.
Right assessment	Obtain medicine-specific observations before administration.	Giving a medicine that lowers BP to a patient already hypotensive.
Right preparation	Use the correct diluent, equipment, asepsis, concentration and label.	Administering an unlabelled syringe prepared by someone else.
Right education	Explain purpose, expected effect, important warnings and what the patient should report.	Patient believes a sedative is an antibiotic and takes extra doses.
Right to refuse	Assess capacity, explain risks, respect refusal and escalate when necessary.	Forcing a competent patient without a lawful basis.
Right documentation	Record immediately and accurately.	Another clinician gives a duplicate dose because the first dose is not charted.
Right response	Reassess therapeutic effect, adverse effects and need for further action.	No reassessment after opioid, insulin, bronchodilator or antihypertensive.

10. The safe administration sequence

CHECK–PREPARE–GIVE–WATCH–RECORD:
CHECK order, patient, indication, allergies, observations and product.
PREPARE calculation, dilution, equipment, label and environment.
GIVE using the correct route, technique, rate and patient communication.
WATCH the response, vital signs, therapeutic effect and adverse effects.
RECORD the dose, time, route, response, omission, refusal or incident.

Step 1 — Prepare yourself and the environment

Perform hand hygiene and use appropriate personal protective equipment.
Reduce interruptions, noise and distractions; keep the preparation area clean and organised.
Confirm adequate lighting and a reliable reference for unfamiliar medicines.
Secure medicines, especially controlled or high-alert products.
Prepare one patient’s medicines at a time and do not pre-chart a dose before it is administered.

Step 2 — Read and assess the order

Read the order completely, including special instructions and monitoring.
Check that the order is current, legible, attributable and within the prescriber’s authority.
Confirm the indication, allergies, contraindications, interactions, pregnancy status where relevant and the last dose.
Check required observations such as BP, pulse, respiratory rate, oxygen saturation, blood glucose, pain score or level of consciousness.
Clarify anything incomplete before opening the medicine.

Step 3 — Select and check the product

Compare the medication label with the order when removing it from storage.
Check generic name, strength, concentration, dosage form, expiry, batch and package integrity.
Compare the label again while preparing and once more at the bedside before administration.
Never use a product that is expired, discoloured, precipitated, cracked, leaking, unlabelled or stored incorrectly.
Separate look-alike/sound-alike and high-alert products according to facility policy.

Step 4 — Calculate, prepare and label

Use the actual concentration in the container, not a remembered concentration.
Write the calculation and units; ask for an independent check when required.
Use oral syringes for oral liquids and appropriately sized syringes for injections.
Do not prepare medication in advance without a label showing patient, medicine, strength, dose, diluent, preparation time and preparer.
Do not mix medicines in one syringe or infusion unless compatibility and policy are confirmed.
For infusions, verify the line, pump, rate, total volume, remaining volume and monitoring plan.

Step 5 — Identify and educate the patient

Use two identifiers and compare with the order.
Explain the medicine, reason, expected effect and important warning symptoms.
Use teach-back: ask the patient or caregiver to explain what they understood.
Protect privacy and dignity, especially during rectal, topical, injectable or reproductive-health medicines.
Check the patient’s ability to swallow, cooperate, protect the airway and remain safely positioned.

Step 6 — Administer and observe

Use the correct technique and rate for the route.
Remain with the patient when the medicine can cause rapid deterioration, sedation, hypotension, hypoglycaemia, arrhythmia or anaphylaxis.
Do not leave oral medicine at the bedside unless self-administration is authorised and safe.
Observe the patient, not only the monitor; early signs of harm may be confusion, work of breathing, rash, pain, agitation or reduced responsiveness.

Step 7 — Reassess and document

Assess whether the intended effect occurred at the appropriate time.
Check for adverse effects, interactions and deterioration.
Document the administration or reason for non-administration immediately.
Communicate outstanding doses, monitoring and concerns during handover.

11. Route-specific safety precautions

Oral administration

Confirm the patient is awake enough to protect the airway and can swallow safely.
Check whether the medicine may be crushed, mixed with food or given through a feeding tube; modified-release and enteric-coated products may be unsafe to crush.
Measure liquids with an oral syringe or calibrated measure, not a household spoon.
Remain until the medicine is swallowed when the patient is confused, at risk of aspiration or receiving a critical medicine.
Record vomiting or spitting out and seek instructions; do not repeat automatically.

Sublingual and buccal administration

Place the medicine in the correct mucosal site and instruct the patient not to chew or swallow unless directed.
Check consciousness, cooperation, oral injury, excessive secretions and aspiration risk.
Monitor for rapid hypotension, dizziness, headache or altered mental status where relevant.

Inhaled and nebulised medicines

Confirm the medicine, nebuliser solution, dose, diluent, driving gas/oxygen flow and prescribed duration.
Position the patient upright where possible and assess respiratory rate, effort, wheeze, air entry and oxygen saturation before and after treatment.
Use the correct mask or mouthpiece; explain slow breathing and allow rest if exhausted.
Monitor for tremor, tachycardia, chest pain, paradoxical bronchospasm or worsening fatigue.
Use infection-control precautions and clean/dispose of equipment according to policy.

Topical, transdermal and ophthalmic/otic medicines

Confirm the exact site and laterality; wrong-eye and wrong-ear errors are preventable.
Inspect skin, eye or ear for injury, infection, bleeding or contraindication.
Wear gloves and avoid contaminating applicator tips.
Remove an old transdermal patch before applying a new one and document site and time.
Heat, fever, occlusion, damaged skin and multiple patches can increase systemic absorption.

Intramuscular and subcutaneous injections

Confirm the medicine is suitable for the route and volume; not every injectable is safe IM or SC.
Assess perfusion, muscle mass, bleeding risk, anticoagulant use, infection, burns and anatomical landmarks.
Use aseptic technique and safe sharps disposal; never recap needles unless a specific safety device requires it.
Rotate sites when repeated injections are authorised and document the site.
Remember that shock and severe vasoconstriction may delay or reduce IM/SC absorption.

Intravenous and intraosseous administration

Confirm line patency, correct access, compatibility, dilution, rate and required flush.
Inspect for pain, swelling, resistance, leaking, redness or coolness suggesting infiltration or extravasation.
Give IV medicines at the prescribed rate; rapid administration can cause acute toxicity.
Use a second check for high-alert infusions, pump settings and paediatric calculations.
For IO access, confirm correct placement and patency according to protocol, secure the device and monitor the limb and insertion site.

12. High-alert medicines and special safeguards

High-alert medicines are not necessarily more likely to cause an error, but the consequences of an error are more severe. Examples in emergency settings may include insulin, concentrated electrolytes, anticoagulants, opioids and sedatives, vasoactive infusions, thrombolytics and medicines requiring weight-based calculations. The exact list is determined by the facility.

Safeguard	How it reduces harm
Standard concentrations	Reduces calculation and dilution variation during emergencies.
Independent double-check	A second qualified person repeats the calculation and compares patient, medicine, dose, route, pump and expiry.
Separate storage	Reduces selection of concentrated or look-alike products.
Clear auxiliary labels	Highlights dilution, route, rate, vesicant status or monitoring requirements.
Smart pumps or dose-error reduction systems	Provides limits and alerts when configured and used correctly.
Required monitoring	Detects hypotension, hypoglycaemia, respiratory depression, bleeding or arrhythmia early.
Restricted access	Limits unauthorised handling and diversion.
Incident learning	Identifies system causes rather than blaming one person and repeating the same error.

Look-alike/sound-alike medicines

Read the full label rather than relying on the first few letters or package colour.
Separate similar names and products physically and use warning labels where policy requires.
Spell the medicine during verbal orders and compare the indication and formulation.
Question an unexpected medicine, dose or concentration instead of assuming the order is correct.
Report recurring confusion so the facility can improve storage, labels, procurement and training.

13. Storage, stock control and medicine quality

Storage checklist

Store medicines at the temperature, humidity and light conditions stated on the label or policy.
Maintain cold-chain medicines in a monitored refrigerator; record minimum and maximum temperatures and act on excursions.
Keep medicines in original labelled containers until the point of preparation.
Separate internal, external, injectable, disinfectant and hazardous products.
Keep controlled medicines secured with restricted access and a current register.
Use FEFO—first expiry, first out—and remove expired or damaged medicines from usable stock.
Do not store medicines on the floor, near heat, in direct sunlight or where unauthorised people can access them.
Keep emergency trays sealed or checked according to policy and replace used, expired or damaged contents immediately.
Do not return a prepared or opened medicine to stock unless the product and policy permit safe return.

Stock and expiry checks

Check	What to verify	Action when abnormal
Product identity	Generic name, strength, dosage form and package.	Quarantine and clarify if uncertain.
Expiry date	Expiry has not passed and is readable.	Remove from use and follow disposal policy.
Physical integrity	No cracks, leaks, broken seal, particles, cloudiness or colour change.	Do not administer; report to pharmacy/supervisor.
Storage condition	Correct temperature, light and humidity.	Quarantine products after an excursion until assessed.
Quantity/balance	Physical stock matches register or electronic record.	Recount, investigate discrepancies and escalate suspected diversion.
Cold chain	Temperature log, alarm and backup plan are functioning.	Do not assume potency after a temperature failure; seek pharmacy guidance.

14. Controlled medicines and witnessing

Controlled or restricted medicines require stricter accountability because diversion, misuse or dosing errors can cause serious harm. The exact schedules, authorised personnel and register requirements follow current Ugandan law and facility policy.

Keep the medicine in a locked, access-controlled location.
Check the prescription/order and patient identity before removing stock.
Record date, time, patient, medicine, strength, quantity removed, balance, prescriber and administering person.
Use an authorised witness for checking, administration, wasting or disposal when required.
Record any partial dose and witnessed wastage immediately; never leave unused medicine on a trolley.
Reconcile physical stock with the register at the required frequency.
Report missing stock, unexplained discrepancy, suspected diversion or forged orders promptly.
Do not borrow controlled medicine from another patient, ward or unofficial source.

15. Safe calculation and dose-volume checks

Every calculation should be based on the actual prescription and product label. A mathematically correct answer can still be clinically wrong if the dose, concentration, weight or maximum limit was misread.

Core formula:
Volume to administer = (Prescribed dose ÷ Dose available) × Volume containing the available dose

Weight-based dose: dose per kg × patient weight in kg
Infusion rate: total volume ÷ time
Concentration: amount of drug ÷ final volume

Calculation example for teaching

An authorised order is for 150 mg. The labelled vial contains 100 mg in 2 mL. The volume is:

(150 mg ÷ 100 mg) × 2 mL = 3 mL

This example demonstrates the method only. In practice, confirm the medicine, route, maximum dose, dilution, patient factors and local protocol before administration.

Decimal and unit safety

Write the unit beside every number during calculation.
Convert grams, milligrams, micrograms, millilitres and units carefully.
Do not use a household spoon for liquid measurement.
Compare the calculated volume with the size of the syringe and the expected clinical volume.
Ask for an independent calculation when a dose is paediatric, weight-based, high-alert, unfamiliar or outside the usual range.
Never round a dose without a protocol or prescriber/pharmacist instruction.

16. Patient-specific precautions

Patient group/condition	Risks	Precautions
Children	Weight-based errors, concentrated liquids, immature organs and limited communication.	Confirm weight, concentration, maximum dose, measuring device and caregiver understanding.
Older or frail adults	Reduced clearance, polypharmacy, falls, delirium, hypotension and sensitivity.	Review medicines, start according to authorised guidance, monitor closely and reassess function.
Pregnant patient	Fetal exposure and altered pharmacokinetics.	Do not delay life-saving care; seek authorised benefit–risk advice and document pregnancy status.
Renal impairment	Accumulation of renally eliminated medicines and electrolyte complications.	Check urine output/history/results, adjust under authorised guidance and monitor.
Liver disease	Reduced metabolism, protein binding and detoxification.	Check history, jaundice, bleeding and interacting medicines; seek review.
Reduced consciousness	Aspiration, inability to consent or report symptoms, airway obstruction.	Assess ABCDE, use a safe route, provide monitoring and seek senior direction.
Shock/poor perfusion	Unreliable IM/SC absorption and altered distribution/clearance.	Use an authorised dependable route and reassess response before repeating.
Allergy history	Anaphylaxis, cross-reactivity and incomplete history.	Clarify reaction, mark record, avoid suspected medicine where possible and prepare emergency response.
Communication difficulty	Wrong history, misunderstanding or inability to report adverse effects.	Use interpreter/communication aids and teach-back; do not guess.
Self-harm or substance exposure	Unknown dose, mixed substances, concealment and recurrent access.	Preserve packaging, assess safety, involve toxicology/senior team and document objectively.

17. Patient education and the right to refuse

Education is part of administration. Use language the patient understands and avoid promising a result that the medicine cannot guarantee.

Explain the medicine’s name or purpose, how it will be given and the expected effect.
State common effects and urgent symptoms that require immediate reporting.
Explain timing, food instructions, missed doses and what not to combine without advice.
Ask the patient to repeat the plan in their own words.
Assess capacity when a patient refuses: understanding, appreciation, reasoning and ability to communicate a choice.
Respect an informed refusal by a competent patient; explain potential consequences, offer alternatives and document.
If capacity is impaired or refusal creates immediate danger, follow emergency, consent and safeguarding policy and seek senior review.

Refusal scenario: A competent adult refuses an analgesic because of a previous severe reaction. Do not pressure or label the patient “difficult.” Clarify the reaction, check the record, inform the prescriber, offer an authorised alternative and document the discussion and decision.

18. Monitoring after administration

The medicine is not “finished” when it leaves the syringe. Monitoring starts before administration and continues for the expected onset, peak and duration.

Medicine effect to monitor	Observations	Escalate when
Analgesia	Pain score, respiratory rate, sedation, BP, oxygen saturation and nausea.	Respiratory depression, severe sedation, hypotension, allergy or uncontrolled pain.
Bronchodilation	Work of breathing, wheeze, air entry, RR, pulse, SpO₂ and chest pain.	Exhaustion, silent chest, worsening hypoxia, arrhythmia or paradoxical bronchospasm.
Insulin/glucose-lowering therapy	Capillary glucose, consciousness, oral intake and signs of hypoglycaemia.	Confusion, seizure, coma, recurrent low glucose or inability to eat safely.
Sedation	Airway, respiratory rate, depth, SpO₂, BP, pulse and level of consciousness.	Airway obstruction, hypoventilation, apnoea, hypotension or unresponsiveness.
Antihypertensive/vasodilator	BP, pulse, perfusion, mental status and symptoms.	Syncope, shock, chest pain, new neurological deficit or severe bradycardia.
Anticoagulant/thrombolytic	Bleeding, neurological status, puncture sites, urine/stool and vital signs.	Major bleeding, sudden headache, neurological change, shock or haematemesis.
Antibiotic	Allergy, infusion reaction, vital signs and clinical response.	Urticaria with airway symptoms, hypotension, wheeze or rapidly worsening condition.

19. Adverse drug reactions and pharmacovigilance

Suspected adverse reactions should be taken seriously even when the medicine is correctly prescribed. The National Drug Authority supports pharmacovigilance systems for collecting and analysing safety reports. Follow the facility’s reporting process and use the current national reporting route.

Immediate response to a suspected reaction

Stop the suspected medicine when safe and clinically appropriate; do not remove life-sustaining treatment without senior support.
Assess ABCDE and call for help early.
Provide emergency treatment within scope and protocol.
Identify the product, strength, route, amount, batch, time and other medicines.
Monitor vital signs and document the sequence objectively.
Record the reaction clearly in the patient record and allergy/alert system when appropriate.
Inform the prescriber, pharmacist and receiving team.
Complete the adverse-event/medication-error report according to facility and national requirements.

20. Medication errors and near misses

Medication errors can occur during prescribing, transcribing, dispensing, preparation, administration or monitoring. A fair safety culture asks what conditions allowed the error: workload, interruptions, stock labelling, staffing, communication, training, equipment, confusing policy or system design.

Error type	Example	Immediate priority
Wrong patient	Medicine administered to a patient with a similar name.	Assess patient and medicine effect; notify team and report.
Wrong medicine	Look-alike/sound-alike product selected.	Identify exposure and monitor for expected toxicity.
Wrong dose/concentration	mg confused with mL or decimal missed.	Calculate actual exposure and seek urgent clinical/toxicology advice.
Wrong route/rate	IV medicine given IM or rapid IV push.	Support ABCDE, monitor route-specific complications and escalate.
Omitted dose	Critical medicine not given or unavailable.	Assess clinical effect and seek instruction; never double the next dose automatically.
Duplicate dose	Earlier dose was not documented during handover.	Stop further doses, assess timing/amount and monitor.
Wrong time	Dose given before minimum interval.	Assess cumulative exposure and inform responsible clinician.
Expired/poor-quality product	Medicine used after expiry or temperature excursion.	Assess patient, quarantine product and notify pharmacy/supervisor.
Near miss	Error caught before reaching the patient.	Correct the process and report for prevention.

Response sequence after an error

SAFE: Stabilise and assess the patient; Alert the responsible clinician and supervisor; Find the facts and preserve evidence; Enter a truthful report and continue monitoring.

Protect the patient and stop further exposure when safe.
Assess ABCDE, vital signs and medicine-specific toxicity.
Call the prescriber, senior clinician, pharmacist or toxicology service.
Identify the exact product, concentration, amount, route, time and patient factors.
Provide treatment and monitoring according to protocol.
Inform the patient/family honestly through the responsible clinician and policy.
Document the clinical facts and complete incident/pharmacovigilance reporting.
Participate in review and corrective action; do not conceal, alter or blame.

21. Emergency medication scenarios

Scenario 1 — Incomplete prescription: An order reads “give ceftriaxone IV” with no dose, diluent or frequency. Correct response: do not guess. Confirm patient, indication, dose, reconstitution, route, timing and prescriber authority before preparation.

Scenario 2 — Wrong concentration discovered: A syringe has been drawn up, but the label concentration does not match the order. Correct response: stop, quarantine the syringe, recalculate from the original product and obtain a second check. Do not “adjust by eye.”

Scenario 3 — Unconscious patient: A routine oral medicine is due while the patient has reduced consciousness and active vomiting. Correct response: withhold the unsafe oral dose, assess airway and glucose, notify the prescriber and document the reason.

Scenario 4 — Unrecorded ambulance dose: The receiving team cannot tell whether analgesia was given. Correct response: contact the transporting team, inspect the record and ask the patient/crew; do not repeat until exposure is clarified unless an authorised emergency protocol directs otherwise.

Scenario 5 — Allergy during infusion: The patient develops urticaria, wheeze and hypotension during an infusion. Correct response: stop the suspected infusion, activate the emergency response, assess ABCDE, give authorised treatment and document/report the reaction.

Scenario 6 — Controlled-drug discrepancy: The physical balance is one ampoule lower than the register. Correct response: secure the stock, recount with a witness, review administration and wastage entries, notify the responsible senior and follow controlled-drug investigation policy.

22. Practical medication administration checklist

Before	During	After
Confirm patient with two identifiers.	Explain and obtain cooperation.	Reassess expected response.
Read complete order and indication.	Use correct route and technique.	Observe for adverse effects.
Check allergy and previous reaction.	Use aseptic technique.	Record drug, dose, route and time.
Check strength, concentration and expiry.	Give at the correct rate.	Document omission, refusal or variation.
Check observations, weight and organ function.	Do not leave critical doses unattended.	Handover next dose and monitoring plan.
Calculate and obtain independent check.	Stop if the patient deteriorates.	Report error, ADR or near miss.

23. Examination and revision questions

Define prescription, medication order, dispensing, administration and medication error.
List the essential components of a complete prescription.
Why should a generic name be used where possible?
Explain why “give 1 mL” is an incomplete injection order.
State the dangers of a trailing zero and a missing leading zero.
What is closed-loop communication and when is it useful?
Describe the steps for receiving a verbal emergency order.
What is medication reconciliation and when should it be performed?
List the expanded rights of medication administration.
What assessments should precede a medicine that may cause respiratory depression?
Why may IM absorption be unreliable in shock?
List six storage precautions for emergency medicines.
What additional controls are needed for controlled medicines?
How should a documentation error be corrected?
What should be recorded after a medicine is refused?
What are look-alike/sound-alike medicines and how can risk be reduced?
Describe the immediate response to a suspected adverse drug reaction.
Differentiate a medication error from a near miss.
What information should be handed over after an ambulance medicine is given?
Describe the SAFE response sequence after a medication error.

24. Key takeaways

A complete prescription prevents guessing: patient, medicine, strength, dose, route, timing, indication, duration and prescriber must be clear.
Verbal orders require necessity, closed-loop read-back, immediate documentation and later authentication according to policy.
Medication safety is a chain from assessment through prescribing, dispensing, administration, monitoring and handover.
The expanded rights include patient, medicine, indication, dose, route, time, assessment, preparation, education, refusal, documentation and response.
High-alert medicines need stronger safeguards, not reliance on memory or speed.
Storage, cold chain, expiry, controlled-drug registers and stock reconciliation are clinical safety responsibilities.
Every administration requires reassessment and documentation; an undocumented dose can become a duplicate dose.
When an error occurs, stabilise the patient, escalate, document honestly and report for learning.
