A typical episode of rigors progresses through three distinct stages:

• 1. Cold Stage (Chill Stage): This is the initial stage where the patient feels intensely cold, even if the room temperature is normal or warm. Symptoms: Uncontrollable shivering and shaking, chattering teeth, pale and cool skin, goosebumps (piloerection). Physiology: The body's thermostat (in the hypothalamus) is suddenly set to a higher temperature due to pyrogens (fever-producing substances, often from infection). The body then tries to generate heat and conserve it to reach this new set point, leading to shivering (muscle activity generates heat) and vasoconstriction in the skin (reduces heat loss). Duration: Can last from a few minutes to an hour or more.
• 2. Hot Stage (Fever Stage / Flush Stage): Follows the cold stage, as the body temperature rises to the new, higher set point. Symptoms: Shivering stops. The patient feels very hot, skin becomes flushed (red) and dry, pulse and respiratory rate increase. Patient may complain of headache, malaise, and thirst. The core body temperature is elevated (fever). Physiology: The body has reached the new higher temperature set by the hypothalamus. Vasodilation (widening of blood vessels in the skin) occurs as the body tries to prevent overheating further, though the core temperature remains high. Duration: Can last for several hours.
• 3. Sweating Stage (Defervescence Stage / Crisis Stage): Occurs as the body temperature begins to fall back towards normal. Symptoms: Profuse sweating (diaphoresis), skin feels warm and moist. Patient may feel tired and weak but often starts to feel some relief from the intense heat. Thirst is common. Physiology: The hypothalamus set point returns to normal (or is lowered by antipyretic medication). The body now needs to lose the excess heat. This is achieved through vasodilation and sweating, which cools the body by evaporation. Duration: Can last for an hour or more.

Management focuses on patient comfort, monitoring, reducing fever, identifying and treating the underlying cause. It's important to treat rigors as a sign of a potentially serious condition.

• General Management Across All Stages: Monitor Vital Signs: Frequently check temperature, pulse, respiration, and blood pressure. Identify and Treat Underlying Cause: This is crucial. Administer prescribed medications (e.g., antibiotics for infection, antimalarials for malaria) promptly. Blood cultures or other investigations may be needed. Maintain Hydration: Encourage oral fluids if tolerated, or administer IV fluids if the patient is unable to drink, vomiting, or severely ill, to replace fluid lost through sweating and increased metabolism. Provide Reassurance: Rigors can be very frightening for the patient. Explain what is happening and provide comfort.
• Management During the Cold Stage (Chill Stage): Keep the Patient Warm: Provide extra blankets, warm clothing. Avoid drafts. This helps the patient feel more comfortable while their body is trying to generate heat. Offer Warm Drinks: If the patient can tolerate oral intake and it's not contraindicated. Administer Antipyretics (Fever Reducers): As prescribed (e.g., paracetamol, ibuprofen). This may help to lower the hypothalamic set point and shorten the cold stage, though it might be more effective once the temperature starts to rise significantly. Avoid Overheating: While keeping them warm, be ready to remove layers as they transition to the hot stage.
• Management During the Hot Stage (Fever Stage): Cooling Measures: > Remove excess blankets and clothing (leave a light sheet or gown). > Tepid Sponging: Use lukewarm water to sponge the skin, especially forehead, neck, armpits, and groin. Avoid cold water as it can cause shivering and increase core temperature. > Fan: A fan can help with evaporative cooling. > Ensure good ventilation in the room. Administer Antipyretics: If not already given or if due, as prescribed. Oral Hygiene: Frequent mouth care as the mouth may become dry. Monitor for Complications: Such as dehydration, confusion, or seizures (especially in children with high fever).
• Management During the Sweating Stage (Defervescence Stage): Keep Patient Dry and Comfortable: Change wet bed linen and clothing frequently to prevent chilling and skin irritation. Maintain Fluid Intake: Encourage fluids to replace what is lost through sweating. Rest: The patient will likely feel exhausted. Allow for adequate rest. Observe: Continue to monitor vital signs as the temperature returns to normal.

Nursing students are expected to uphold professional standards as they learn and practice. These standards guide their behavior, learning, and interaction with patients, colleagues, and the educational institution.

• 1. Professionalism and Accountability:Behave in a manner that reflects positively on the nursing profession. This includes punctuality, appropriate attire, preparedness for clinicals and classes, and taking responsibility for one's actions and learning.
• 2. Ethical Conduct:Adhere to the nursing code of ethics. Respect patient rights, maintain confidentiality, act with integrity, and report any unethical behavior observed.
• 3. Patient Safety:Prioritize patient safety at all times. Follow safety protocols, report errors or near misses, and seek supervision when unsure about a procedure or task.
• 4. Respect for Dignity and Diversity:Treat all patients, families, colleagues, and instructors with respect, regardless of their cultural background, beliefs, age, gender, or socioeconomic status. Provide culturally sensitive care.
• 5. Competence and Skill Development:Actively engage in learning and strive to develop the necessary knowledge, skills, and critical thinking abilities for safe and effective nursing care. Practice within one's scope of learning and seek help when needed.
• 6. Effective Communication:Communicate clearly, respectfully, and therapeutically with patients, families, and the healthcare team. Use appropriate documentation methods.
• 7. Collaboration and Teamwork:Work cooperatively with other students, nurses, healthcare professionals, and instructors as part of the healthcare team.
• 8. Maintaining Confidentiality (Privacy):Protect patient information and privacy according to legal and ethical guidelines (e.g., HIPAA or local equivalents). Do not discuss patient information inappropriately.
• 9. Lifelong Learning and Self-Improvement:Demonstrate a commitment to continuous learning, reflect on practice, accept constructive feedback, and actively seek opportunities for growth.
• 10. Adherence to Policies and Procedures:Follow the rules, regulations, and policies of the educational institution and the clinical placement facility.
• 11. Advocacy for Patients:Learn to speak up for patients' rights and best interests, ensuring their needs are met and their voices are heard, under appropriate supervision.
• 12. Maintaining Professional Boundaries:Establish and maintain appropriate professional relationships with patients, their families, and colleagues, avoiding personal or inappropriate involvement.

These are fundamental guidelines that help nurses make ethical decisions in their practice.

• 1. Autonomy (Self-Determination):Respecting the patient's right to make their own decisions about their healthcare, even if those decisions differ from what the healthcare provider believes is best. This includes the right to informed consent (understanding the treatment, risks, benefits, alternatives before agreeing) and the right to refuse treatment. Example: Ensuring a patient fully understands a surgical procedure before they sign the consent form.
• 2. Beneficence (Doing Good):The principle of acting in ways that promote the well-being and best interests of the patient. Nurses have a duty to do good and take positive actions to help others. Example: Administering pain medication promptly to a patient in pain, or providing health education to promote wellness.
• 3. Non-maleficence (Do No Harm):The obligation to avoid causing harm, or to minimize harm, to patients. This includes not only intentional harm but also harm due to carelessness, negligence, or incompetence. If harm cannot be avoided, the nurse should ensure the benefits outweigh the risks. Example: Carefully checking medication dosages to prevent errors, or using proper technique during procedures to avoid injury.
• 4. Justice (Fairness):Treating all patients fairly and equitably, without discrimination based on age, race, gender, religion, socioeconomic status, or other factors. This also involves the fair allocation of healthcare resources. Example: Providing the same quality of care to all patients on a ward, regardless of their background, or advocating for fair distribution of limited supplies.
• 5. Fidelity (Faithfulness/Loyalty):Being faithful to commitments, responsibilities, and agreements made to patients, colleagues, and the profession. This includes keeping promises, maintaining competence, and being trustworthy. Example: Returning to a patient at the time promised, or advocating for a patient's wishes as discussed.
• 6. Veracity (Truthfulness):The principle of being honest and telling the truth. Nurses have an obligation to provide accurate information to patients and not deceive them. Example: Honestly answering a patient's questions about their condition or treatment, within the scope of nursing practice and institutional policy.
• 7. Confidentiality (Privacy):Protecting private patient information and sharing it only with authorized individuals involved in their care, or when legally required. This is a cornerstone of the nurse-patient relationship. Example: Not discussing a patient's condition in public areas or with people not involved in their care.
• 8. Accountability:Being answerable for one's own actions and professional conduct. This means accepting responsibility for the nursing care provided and for maintaining professional standards. Example: Reporting a medication error one has made and taking steps to rectify it and prevent future occurrences.

• Age:Newborns and infants have a faster respiratory rate (e.g., 30-60 breaths/minute) which gradually decreases with age, reaching adult rates (12-20 breaths/minute) by adolescence. Older adults may have slightly increased rates or shallower breathing.
• Physical Activity / Exercise:Increased muscle activity requires more oxygen and produces more carbon dioxide, leading to an increase in both the rate and depth of respiration to meet metabolic demands.
• Emotional State (Stress, Anxiety, Pain):Strong emotions like fear, anxiety, excitement, or severe pain can stimulate the sympathetic nervous system, increasing respiratory rate and depth. Depression may sometimes decrease it.
• Body Temperature (Fever):An increase in body temperature (fever) increases metabolic rate, leading to an increased respiratory rate to help dissipate heat and meet higher oxygen demands. Hypothermia can decrease it.
• Altitude:At higher altitudes, the partial pressure of oxygen in the air is lower. The body compensates by increasing respiratory rate and depth to take in more oxygen (acclimatization).
• Medications: Opioids (e.g., morphine, codeine), sedatives, and anesthetics can depress the respiratory center in the brain, decreasing respiratory rate and depth. Stimulants (e.g., amphetamines, caffeine in high doses) can increase respiratory rate. Bronchodilators (e.g., salbutamol) affect airway diameter but indirectly can ease breathing.
• Diseases and Medical Conditions: Respiratory Diseases: Conditions like asthma, COPD (chronic obstructive pulmonary disease), pneumonia, pulmonary embolism, and pneumothorax directly affect lung function and breathing patterns. Cardiovascular Diseases: Heart failure can cause fluid buildup in the lungs (pulmonary edema), leading to shortness of breath and altered respiration. Metabolic Acidosis: (e.g., diabetic ketoacidosis, kidney failure) The body tries to compensate by increasing respiratory rate and depth to blow off CO2 (Kussmaul breathing). Neurological Conditions: Brainstem injuries, strokes, or conditions affecting respiratory muscles (e.g., Guillain-Barré syndrome, myasthenia gravis) can impair control of breathing. Anemia: Reduced oxygen-carrying capacity of the blood can lead to increased respiratory rate to compensate.
• Pain:Acute pain, especially chest or abdominal pain, can cause shallow breathing and an increased respiratory rate to avoid aggravating the pain.
• Body Position:Lying flat (supine) can make breathing more difficult for some individuals, especially those with heart failure or obesity. Sitting upright (e.g., Fowler's position) often facilitates easier breathing.
• Smoking:Chronic smoking damages lung tissue and airways, often leading to increased respiratory rate at rest and during exertion, and conditions like COPD.
• Metabolic Rate:Conditions that increase metabolic rate (e.g., hyperthyroidism) will increase respiratory rate, while those that decrease it (e.g., hypothyroidism) can decrease it.
• Voluntary Control:While breathing is largely involuntary, it can be consciously controlled for short periods (e.g., holding breath, deep breathing exercises).

• Eupnea:Normal, quiet, effortless breathing (normal rate and rhythm).
• Tachypnea:Abnormally rapid respiratory rate (e.g., >20 breaths/minute in an adult at rest). Often shallow.
• Bradypnea:Abnormally slow respiratory rate (e.g., <12 breaths/minute in an adult at rest).
• Apnea:Temporary cessation (stopping) of breathing. Sleep apnea is a common disorder involving recurrent apnea during sleep.
• Dyspnea:Difficult or labored breathing; a subjective feeling of shortness of breath.
• Orthopnea:Difficulty breathing except when in an upright position (sitting or standing). Common in heart failure.
• Hyperpnea:Increased depth of respiration, with or without an increased rate. Often seen after exercise.
• Hypopnea:Abnormally shallow respirations.
• Hyperventilation:Increased rate and depth of breathing that results in excessive exhalation of CO2 (leading to respiratory alkalosis). Can be caused by anxiety, head injury, or certain metabolic conditions.
• Hypoventilation:Decreased rate and/or depth of breathing that results in inadequate exhalation of CO2 (leading to respiratory acidosis). Can be caused by opioids, chest wall deformities, or neuromuscular diseases.
• Kussmaul Breathing:Deep, rapid, and labored breathing, often associated with severe metabolic acidosis (like diabetic ketoacidosis) as the body tries to expel CO2.
• Cheyne-Stokes Respiration:A pattern of breathing characterized by gradually increasing depth and sometimes rate of respirations, followed by a gradual decrease, resulting in a period of apnea. Often seen in heart failure or brain damage.
• Biot's (Ataxic) Respiration:Irregular breathing pattern with periods of apnea interspersed with breaths of similar depth. Often indicates severe brainstem damage.
• Stridor:A harsh, high-pitched sound during inspiration, usually due to obstruction in the upper airway (larynx or trachea).
• Wheezing:A high-pitched whistling sound, usually heard during exhalation, caused by narrowed airways (e.g., in asthma or COPD).
• Crackles (Rales):Fine or coarse bubbling or crackling sounds heard during inspiration, caused by fluid or mucus in the small airways or alveoli (e.g., in pneumonia, heart failure).
• Rhonchi:Low-pitched, snoring or rattling sounds, usually heard during exhalation, caused by secretions or obstruction in larger airways. Often clear with coughing.
• Cyanosis:Bluish discoloration of the skin, lips, and nail beds due to insufficient oxygen in the blood.
• Hypoxia:Insufficient oxygen supply to the tissues.
• Hypoxemia:Low oxygen levels in the arterial blood.
