UNMEB PALLIATIVE CARE DND 2023

Colorectal cancer is the most common gastrointestinal malignancy globally and frequently presents at advanced stages requiring palliative care. High incidence rates, especially in developed countries, combined with late diagnosis due to asymptomatic early disease, make it the leading GI cancer in palliative settings. It causes bowel obstruction, bleeding, pain, and cachexia that significantly impair quality of life.

Pain undertreatment in palliative care stems primarily from knowledge deficits - lack of understanding of pain assessment, opioid pharmacology, addiction myths, and fear of side effects. Many healthcare providers have inadequate training in palliative pain management, leading to "opiophobia" and poor pain control. This is the most systemic and correctable barrier compared to individual staff issues or workload.

Being emotional (losing composure, crying with patient, becoming overly involved) compromises therapeutic boundaries and impairs objective assessment. While empathy is crucial, emotional over-involvement prevents active listening, clouds judgment, and may burden the patient with the nurse's feelings. Professional detachment with compassion is the ideal stance.

Pain is the most prevalent and feared symptom in cancer, affecting 70-90% of advanced cancer patients. It results from tumor infiltration of nerves/compression of structures, treatment side effects, or inflammatory processes. Pain is multidimensional (physical, emotional, spiritual) and the primary driver for seeking palliative care. Effective pain control is the cornerstone of cancer palliation.

Cancer cachexia and protein-calorie malnutrition are the primary causes of impaired wound healing in palliative patients. Cachexia involves muscle wasting, hypoalbuminemia, and metabolic derangements that deprive tissues of essential building blocks. Poor nutrition reduces collagen synthesis, angiogenesis, and immune function. Combined with anemia, hypoxia, and metabolic demands of cancer, wounds fail to progress through normal healing phases.

Buscopan (hyoscine butylbromide) is the drug of choice for terminal secretions/death rattle. It's an antimuscarinic that reduces respiratory secretions by blocking parasympathetic stimulation. Given subcutaneously (20-40 mg stat, then 20-80 mg/24h via syringe driver). Unlike atropine, it doesn't cross BBB significantly, causing fewer CNS side effects. It effectively dries secretions within 30-60 minutes.

"Reaching everyone is possible" is false and NOT a challenge - it's an aspiration. In Uganda, reaching all palliative care patients is impossible due to severe resource constraints, geographic barriers, poverty, and lack of services. Only ~10% of those needing palliative care actually receive it. The statement describes an ideal, not a challenge. All other options are documented major challenges in Ugandan palliative care delivery.

Spiritual distress manifests as profound isolation and loneliness - feeling disconnected from self, others, meaning, and transcendence. Patients question life's purpose, feel abandoned by God/higher power, and experience existential loneliness even in company. This differs from psychological denial or bargaining (part of grief stages). Spiritual distress requires chaplaincy referral, life review, reconciliation, and presence.

Social isolation is harmful and inappropriate in end-of-life care. Social connection and support are fundamental human needs at life's end. Isolation increases suffering, depression, and spiritual distress. The goal is to facilitate visits, connections, and legacy activities. Social isolation directly contradicts palliative care principles of holistic support and relationship-centered care.

SVCS affects the upper body only (above the heart). Lower limb pallor suggests anemia, arterial insufficiency, or other pathology, not SVC obstruction. SVCS causes superior vena cava obstruction leading to venous congestion in head, neck, arms, and upper torso. Symptoms are all above the diaphragm.

The most critical and life-threatening sign of opioid toxicity is **respiratory depression**, which is encapsulated by "Respiratory distress" in this option. Opioids depress the central nervous system, leading to slowed and shallow breathing, which can progress to respiratory arrest. While "insomnia" is typically associated with opioid withdrawal rather than acute toxicity (which usually causes drowsiness/sedation), the presence of "Respiratory distress" makes this option the most accurate indicator of a severe and dangerous level of opioid toxicity among the choices provided. In a multiple-choice question where the best option must be chosen, the life-threatening nature of respiratory compromise takes precedence.

Key signs of opioid toxicity include:

• **Respiratory depression:** Slowed, shallow, or absent breathing.
• **Miosis (pinpoint pupils):** Very constricted pupils.
• **Sedation/Decreased level of consciousness:** Ranging from drowsiness to unresponsiveness.
• Hypotension (low blood pressure) and bradycardia (slow heart rate) can also occur.

Symptoms like irritability, restlessness, and insomnia are more commonly associated with opioid withdrawal.

Maternal presence is the most powerful non-pharmacological analgesic for children. Skin-to-skin contact, breastfeeding, and maternal voice activate oxytocin release, reduce cortisol, and provide security and comfort that modulates pain perception. This is evidence-based for procedures and chronic pain. The mother's presence provides distraction, emotional support, and helps child cope with painful stimuli.

Constipation is the most common and persistent side effect of opioids, affecting >95% of patients. Opioids bind to mu receptors in the gut, reducing peristalsis and increasing sphincter tone. It is dose-dependent and tolerance does NOT develop. Must be prevented proactively with laxatives (stimulant + stool softener) started at same time as opioid, not waiting for constipation to occur.

Hospice care NEVER aims to hasten death. This is a fundamental ethical principle distinguishing palliative care from euthanasia. Hospice focuses on comfort, dignity, and quality of life until natural death occurs. Hastening death violates the principle of non-maleficence and is illegal. The goal is to neither hasten nor postpone death, but to support living fully until death.

Clinicians consistently report insufficient time as a major barrier to end-of-life conversations. These discussions require 30-60 minutes of uninterrupted time to assess understanding, explore values, discuss options, and answer questions. In busy clinical settings with high patient loads, finding this time is challenging. This is a systems issue requiring protected time and scheduling.

NOT following patient's decision violates autonomy and the SPIKES protocol. Patients have the right to determine how much information they want and who should receive it. Some may not want full disclosure. The nurse must respect these preferences while ensuring someone (family member) can act as information receiver. Imposing information against will causes psychological harm.

Route of administration does NOT determine addiction risk - this question appears flawed. However, oral route has the lowest addiction potential because slower absorption produces less euphoria. Addiction in palliative care is <1% regardless of route. The key is indication - therapeutic use for pain doesn't cause addiction; recreational use seeking euphoria does. All parenteral routes (IV, SC, IM) have higher abuse potential.

Autonomy is paramount in end-of-life care. Patients have the right to refuse any treatment, including artificial nutrition/hydration, CPR, and hospitalization. This is protected by law and ethics. Respecting wishes may mean allowing natural death, stopping ineffective treatments, or focusing only on comfort. This is the principle of self-determination in palliative care.

Decreasing intake is a sign of APPROACHING death (days to weeks before), not actual death. It's part of the pre-active dying phase as the body naturally shuts down. Actual death signs are: cessation of breathing, heartbeat, pulse, fixed pupils, and rigor mortis (stiffness) occurring AFTER death. Decreased intake is reversible and not diagnostic of death.

Low self-esteem is a psychological manifestation of chronic stress in palliative patients. It reflects negative self-evaluation, feelings of worthlessness, and loss of identity due to functional decline, dependency, and body image changes. It affects coping and quality of life. Other options are cognitive (indecision, poor concentration) or physiological (inability to relax) symptoms rather than purely psychological.
