Advanced Pain & Symptom Management

🧠

PAINAD Scale — Pain in Advanced Dementia

For non-communicating patients (0–10 total)

Used when self-report is impossible. Score 0–2 in each of 5 domains. Total ≥4 indicates significant pain requiring intervention.

Domain	0 — Normal	1 — Moderate	2 — Severe
Breathing	Normal	Occasional laboured breathing / short periods of hyperventilation	Noisy laboured breathing; long hyperventilation; Cheyne-Stokes
Negative Vocalisation	None	Occasional moan/groan; low-level negative/disapproving speech	Repeated troubled calling out; loud moaning/groaning; crying
Facial Expression	Smiling or inexpressive	Sad; frightened; frowning	Facial grimacing
Body Language	Relaxed	Tense; distressed pacing; fidgeting	Rigid; fists clenched; knees pulled up; pulling/pushing away; striking out
Consolability	No need to console	Distracted or reassured by voice/touch	Unable to console, distract, or reassure

Interpretation 1–3 mild | 4–6 moderate | 7–10 severe. Document score, intervene, reassess after 30 min. Behavioural change is often the first pain signal in dementia.

🔬

Pain Mechanism Classification

Nociceptive · Neuropathic · Mixed · Nociplastic

Nociceptive Pain

Somatic: Well-localised, aching/throbbing. Bone mets, incision wounds. Responds well to opioids + NSAIDs.

Visceral: Poorly localised, colicky/cramping, may refer. Liver capsule, bowel obstruction. Opioids + antispasmodics.

Neuropathic Pain

Burning, electric shock, shooting, allodynia (pain to light touch), hyperalgesia. Tumour invasion of nerves/plexus. Responds less to opioids alone — add adjuvants: amitriptyline, gabapentin, ketamine.

Nociplastic Pain

Altered pain processing without clear nociceptive or neuropathic cause. Central sensitisation. Common in fibromyalgia, chronic cancer survivors. Multi-modal rehabilitation approach.

Mixed Pain

Most advanced cancer pain — combination of nociceptive + neuropathic components. Requires multi-mechanism treatment strategy.

💛

Total Pain Concept

Cicely Saunders, 1964

Pain in palliative care is never purely physical. The nurse must assess and address all four domains.

Physical

Tumour pressure
Bone metastases
Nerve infiltration
Treatment side effects

Psychological

Fear of dying
Anxiety/depression
Loss of control
Fear of pain itself

Spiritual

"Why me?"
Meaning/purpose
Unresolved grief
Religious distress

Nursing implication: Opioids alone will not control total pain. Holistic assessment and team collaboration are essential.

⚡

Pain Crisis Recognition

Uncontrolled severe pain emergency

Crisis Criteria: NRS ≥8 + ANY of below

Tachycardia (HR >100) — autonomic response to severe pain
Diaphoresis (profuse sweating)
Hypertension (sudden spike from baseline)
Agitation, distress, inability to be redirected
Respiratory splinting (avoiding deep breaths — rib mets/pleuritis)
Uncontrolled incident pain from carer movement

Immediate Nursing Actions

Stop triggering activity (movement, dressing change)

Administer prescribed breakthrough/PRN opioid immediately

Notify prescriber for urgent review/rescue dose

Re-assess NRS + autonomic signs at 20–30 min

Document: time, NRS, drug given, response

📊

Pain Pattern Classification

Background · Breakthrough · Incident

Background Pain

Constant persistent pain present ≥12h/day. Managed with scheduled around-the-clock (ATC) opioids — modified-release oral or syringe driver SC infusion.

Breakthrough Pain (Spontaneous)

Transient flare superimposed on controlled background pain. Unpredictable, usually <30 min duration. Breakthrough dose = 1/6th of 24h total opioid dose, available q1h PRN.

Incident Pain

Predictable pain triggered by specific movement or activity (dressing, turning, mobilising). Pre-medicate 20–30 min before the triggering event with oral IR opioid. Fentanyl buccal/intranasal acts fastest (10–15 min onset) — ideal for this pattern.

Key distinction: Incident pain with movement does NOT indicate background pain is uncontrolled — it needs a separate management strategy.

WHO Step 3 — Strong Opioids: Reserved for moderate-severe pain (NRS ≥5) not controlled by Step 2 (weak opioids). No ceiling dose except for side effects. Prescribing in GCC is restricted to specialist physicians for controlled substances.

Equianalgesic Reference Table

Approximate oral morphine equivalents (OME)

Opioid	Route	Dose	= Oral Morphine	Key Notes
Morphine Gold Standard	Oral	10 mg	10 mg	Reference drug; convert all others to OME
Morphine	SC / IV	5 mg	10 mg	SC:Oral ratio = 1:2; IV same as SC
Hydromorphone Renal Safe	Oral	1.3–2 mg	10 mg	~7.5x potency; preferred in renal impairment
Hydromorphone	SC / IV	1 mg	15 mg oral morphine	Less metabolite accumulation in renal failure
Oxycodone	Oral	6.7 mg	10 mg	~1.5x more potent than oral morphine
Fentanyl Patch	Transdermal	25 mcg/h	~60–90 mg/24h	Use 90mg/24h OME ≈ 25mcg/h for conservative start
Buprenorphine Patch	Transdermal	35 mcg/h	~84 mg/24h	Partial agonist; ceiling effect at high doses
Codeine Step 2	Oral	100 mg	10 mg	Prodrug; CYP2D6 variation in GCC population
Tramadol Step 2	Oral	100 mg	10 mg	Also SNRI activity; seizure risk

Methadone: Complex non-linear conversion — SPECIALIST ONLY. Ratios vary 4:1 to 20:1 depending on prior morphine dose. QTc monitoring mandatory. Do not convert independently.

Morphine — Clinical Details

WHO Gold Standard Step 3 Opioid

Dosing Regimens

Immediate release (IR) oral: q4h (6 doses/24h) + PRN breakthrough q1h
Modified release (MR) oral: BD (every 12h) — once 24h total established from IR titration
SC infusion: Half the oral 24h dose over 24h via syringe driver
IV: Same as SC dose (1:1 SC:IV)

Breakthrough Dose

= 1/6th of total 24h opioid dose. If patient uses >3–4 breakthroughs/24h, consider increasing background dose by 25–33%.

Cautions

Renal failure: active metabolite M6G accumulates → sedation, respiratory depression. Use hydromorphone instead.
Hepatic failure: increased bioavailability, reduce dose
Elderly: start low, go slow — begin at 2.5mg IR q4h

🩹

Fentanyl Patch — Nursing Protocol

Transdermal, 72-hour delivery

Application

Flat, non-irritated skin on upper chest/arm/back. Avoid bony prominences.
Clip (do not shave) hair if needed. Clean with water — no soap/alcohol.
Apply with palm pressure for 30 seconds. Document site and time.
Change every 72 hours. Rotate sites.

Onset & Titration

Onset 12–24h. Full effect at 24–72h. Continue oral opioid for first 12h after first patch. NOT suitable for rapidly escalating pain.

NEVER apply heat over patch — heating pad, hot bath, fever >38°C increase fentanyl absorption dramatically → risk of overdose. Educate patient and family.

Conversion (Conservative)

Oral morphine 90mg/24h ≈ Fentanyl 25mcg/h patch. Use lower estimate when uncertain (patient can use breakthrough oral opioid for first 24h).

Disposal

Fold sticky sides together. Dispose in clinical waste. Residual fentanyl remains — do not cut or flush patches.

💉

Hydromorphone

Preferred in Renal Impairment

7.5× more potent than morphine (oral). Unlike morphine, its metabolite (hydromorphone-3-glucuronide) does not cause significant opioid toxicity in renal failure.

When to Use

eGFR <30 or on dialysis
Morphine-induced neurotoxicity (myoclonus, hallucinations)
Opioid rotation for inadequate analgesia or intolerable side effects

Opioid Rotation Rule

When rotating opioids, calculate new drug OME, then reduce by 25–30% for incomplete cross-tolerance. Reassess within 24h.

⚗️

Opioid Side Effect Management

Anticipate, prevent, treat

Side Effect	Management
Constipation	Stimulant laxative (senna) from Day 1 — does NOT resolve with time
Nausea (1st week)	Haloperidol 0.5–1.5mg BD or metoclopramide; usually resolves day 5–7
Sedation (initial)	Usually resolves in 48–72h; if persistent, consider dose reduction or rotation
Pruritus	Ondansetron, low-dose naloxone (0.5 mcg/kg/h IV — does NOT reverse analgesia)
Respiratory depression	If RR <8 + unrousable: naloxone 40mcg IV q2min titrated; not needed for sleepy but rousable patient
Dry mouth	Regular mouth care q2h; ice chips; artificial saliva

24-Hour Opioid Dose Converter

Calculate equivalent oral morphine dose and derived doses. Use as a clinical guide only — always verify with pharmacist/physician.

🩺

Epidural Analgesia — Nursing Management

Thoracic & Lumbar epidural infusions

Indications by Level

Thoracic epidural (T4–T10): Rib fractures, thoracotomy, upper abdominal surgery, chest wall malignancy
Lumbar epidural (L1–L4): Pelvic malignancy, lower limb pain, colorectal/gynaecological cancer
PCEA (Patient-Controlled Epidural Analgesia): Patient delivers bolus within programmed limits — document bolus attempts vs delivered

Typical Drug Combinations

Levobupivacaine 0.1–0.125% + Fentanyl 2–4 mcg/ml (most common)
Levobupivacaine + Morphine (preservative-free) for longer-acting coverage
Plain levobupivacaine when opioid side effects intolerable

Nursing Monitoring Protocol

Sensory block level: Ice test or ethyl chloride spray — document dermatome level q4h. Level above T4 = call physician (phrenic nerve risk).

Motor function (Bromage scale): 0=full movement, 3=unable to flex. Bromage >1 = reduce infusion rate, call team.

Blood pressure: Hypotension from sympathetic block — baseline every 30 min for first 4h, then q1-2h. IV fluid bolus if SBP drops >20%.

Urinary retention: Most epidural patients require urinary catheter. Monitor hourly output.

Pruritus: Opioid effect — ondansetron 4mg IV or low-dose naloxone infusion.

Respiratory depression: Monitor RR and sedation score q1h. Have naloxone at bedside. SpO2 continuous if opioid epidural.

Epidural Catheter Safety — Check catheter site for redness, swelling, leakage. Never inject IV drugs into epidural line. Label line clearly "EPIDURAL — NOT IV". Report any neurological deficit (back pain + leg weakness + bowel/bladder change = epidural haematoma/abscess emergency — call physician immediately).

⚙️

Intrathecal Drug Delivery

Implanted pump — specialist centre

Delivers opioid ± local anaesthetic directly into CSF space. Morphine intrathecal is ~300× more potent than oral. Used for refractory pain when side effects limit oral/SC dose escalation.

Nursing Role

Patient carries device card — verify pump model, drug, concentration, rate
Refill appointments: typically every 1–3 months at specialist centre — nurse does NOT refill pump unless trained and credentialed
Programming checks: no dose changes without specialist telemetry/programmer
Monitor for: respiratory depression (highest risk first 24h post-refill), infection at pump site, catheter migration (sudden loss of pain control)
MRI: some pumps MRI-conditional — check card before any scan, may need to pause/empty pump

Pump Failure Alert: If patient presents with uncontrolled pain AND has intrathecal pump — suspect pump/catheter failure. Contact implanting centre immediately. Bridge with oral opioids (calculate from intrathecal dose carefully — extreme potency difference).

🎯

Nerve Blocks & Neuromodulation

Specialist procedures — nursing awareness

Coeliac Plexus Block

For upper abdominal malignancy (pancreatic cancer). Destroys coeliac plexus nerves. Provides pain relief in 70–90% of cases for 2–6 months. Post-procedure: monitor for orthostatic hypotension, diarrhoea (2–3 days), haematuria.

Superior Hypogastric Plexus Block

Pelvic malignancy (cervical, rectal, bladder cancer). Post-procedure: monitor BP, urinary function.

Spinal Cord Stimulation (SCS)

Implanted lead in epidural space — generates paresthesia masking pain signal
Patient carries SCS device card and external controller (magnet)
Magnet: can turn stimulator on/off. Instruct patient not to leave near electronics.
MRI: most SCS systems NOT MRI compatible — always check before imaging
Activities: no MRI, no diathermy, avoid heavy vibration/impact

Nursing role in all interventional procedures: Patient education, consent verification, post-procedure monitoring, recognising complications, and facilitating specialist follow-up.

🫁

Refractory Dyspnoea

Breathlessness unresponsive to reversible causes

First: Treat reversible causes — pleural effusion drainage, bronchospasm, pulmonary oedema, anaemia, infection. Palliative symptom control when reversible causes excluded or not appropriate.

Opioids for Dyspnoea

Morphine 2.5–5mg SC/oral q4h — strongest evidence for dyspnoea in advanced disease. Mechanism: reduces ventilatory response to CO2, reduces anxiety of breathlessness. Does NOT significantly reduce SpO2 in correctly dosed patients.

Benzodiazepines

Lorazepam 0.5–1mg sublingual/oral q4–6h — for dyspnoea-anxiety cycle. Midazolam 2.5–5mg SC PRN for acute episodes. Not first-line alone — combine with opioid.

Non-Pharmacological

Fan therapy: Handheld fan directed at face/nose — stimulates trigeminal nerve, proven to reduce dyspnoea perception. First-line non-drug intervention.
Open window/cool room, upright positioning
Breathing techniques, anxiety management
HFNC (High-Flow Nasal Cannula): Can provide symptomatic relief in palliative patients not pursuing ventilation — decision with patient/family/team

🤢

Intractable Nausea & Vomiting

Refractory to single-agent antiemetics

Cause-Based Approach

Cause	Preferred Agent
Opioid-induced (CTZ)	Haloperidol 0.5–1.5mg SC/oral
Gastric stasis/obstruction	Metoclopramide 10mg q6h (if no complete obstruction)
Vestibular/motion	Cyclizine 50mg TDS
Raised ICP	Cyclizine + dexamethasone
Bowel obstruction	Haloperidol + hyoscine butylbromide + octreotide (reduces secretions)
Chemotherapy	Ondansetron 8mg + dexamethasone + aprepitant

Combination SC Infusion (Syringe Driver)

When oral route lost: Haloperidol + Cyclizine covers multiple receptor pathways (D2 block + antihistamine + anticholinergic). Add Ondansetron if 5HT3 component suspected (opioid-related/chemo).

Check compatibility before combining drugs in syringe driver. Cyclizine is precipitate-prone with saline — use water for injection as diluent.

🧂

Malignant Hypercalcaemia

Oncological emergency — corrected Ca >2.6 mmol/L

Clinical Features (Mnemonic: Groans, Bones, Moans, Psychic)

Groans: Nausea, vomiting, constipation, abdominal pain
Bones: Bone pain, pathological fracture
Moans: Fatigue, polyuria, polydipsia, muscle weakness
Psychic: Confusion, depression, altered consciousness

Management Protocol

IV Saline: 2–4 L/24h (restores GFR, increases Ca excretion). Monitor fluid balance — avoid in cardiac/renal failure.

Zoledronic Acid 4mg IV over 15 min in 100ml NS. Most potent bisphosphonate. Onset 48–72h — do NOT discharge immediately after infusion.

Corticosteroids: Dexamethasone for haematological malignancy-related hypercalcaemia (myeloma, lymphoma).

Treat underlying malignancy: Definitive treatment — bisphosphonate is bridge.

Renal check before zoledronic acid: eGFR >35 required. Adjust dose or use pamidronate if borderline. Hypercalcaemia itself causes renal impairment — recheck after hydration.

🩻

Superior Vena Cava Obstruction

Oncological emergency — SVC syndrome

Recognition

Progressive facial oedema — worse in morning, "plethoric" appearance
Arm and neck oedema
Distended neck and chest wall veins (non-pulsatile)
Headache, visual changes, cognitive impairment (raised ICP)
Pemberton's Sign: Arms raised above head → facial/neck congestion within 1 minute (diagnostic manoeuvre)

Causes

Lung cancer (70%), lymphoma (15%), metastatic disease, mediastinal tumours, PICC/port-related thrombosis.

Management

Dexamethasone 8–16mg IV/oral — reduces tumour oedema, temporary symptomatic relief within hours

Urgent oncology referral — for stenting (interventional radiology) or radiotherapy

SVC stenting: Fastest relief (often within 24h). Treatment of choice for rapid deterioration.

Radiotherapy: For radiosensitive tumours (SCLC, lymphoma). Onset days to weeks.

Avoid: Do NOT insert PICC or peripheral IV into arms/hands (raises venous pressure). Use lower limb IV or central access femoral.

Syringe Driver Indications & Setup

CADD Solis / McKinley T34 (commonest in GCC)

Indications for SC Syringe Driver

Inability to swallow (dysphagia, deteriorating consciousness)
Intractable nausea/vomiting — oral drugs not absorbed
Terminal phase / last hours of life
Poor GI absorption (malabsorption, short bowel)
Rapid dose titration needed

McKinley T34 vs CADD Solis

Feature	T34	CADD Solis
Syringe size	Up to 30ml	Up to 100ml
Rate display	ml/h	ml/h
Bolus facility	Yes	Yes
Common in GCC	Most hospitals	Oncology/palliative

SC Site Care

Preferred sites: anterior chest wall, anterior abdomen, upper arm, thigh
Avoid: oedematous areas, irradiated skin, bony prominences, ascitic skin
Inspect site every 4 hours — redness, induration, leaking, bleeding
Rotate sites every 3–7 days or when signs of irritation
Maximum SC infusion rate: 2–3 ml/h at one site (higher rates cause tissue irritation)
Use 24G butterfly needle (less trauma) or dedicated SC cannula

Line Checks

Check line patency by aspirating small volume
No blood return expected (SC not IV)
Flush with 0.9% NaCl or WFI if occlusion alarm

🔬

Drug Compatibility in Syringe Driver

Common combinations and incompatibilities

Common Compatible Combinations

Combination	Use
Morphine + Midazolam	Pain + anxiety/agitation. Most used.
Morphine + Haloperidol	Pain + nausea. Well established.
Morphine + Midazolam + Haloperidol	Pain + anxiety + nausea. Three-way mix.
Morphine + Hyoscine Butylbromide	Pain + respiratory secretions ("death rattle")
Hydromorphone + Midazolam	Renal failure patients
Octreotide + compatible opioid	Malignant bowel obstruction secretions

Incompatible — DO NOT Mix

Diazepam — precipitates Prochlorperazine — precipitates Chlorpromazine — irritant Phenobarbitone (high conc.)

Always check compatibility with your hospital pharmacist or Palliative Drugs compatibility database (palliatviedrugs.com) before mixing. Cyclizine + morphine at high concentrations can precipitate. Use minimum concentration and diluent as specified.

Diluents

Water for Injection (WFI) — default, most compatible
0.9% Sodium Chloride — suitable for most but NOT cyclizine
Never use dextrose (degrades morphine)

⚠️

Syringe Driver Troubleshooting

Alarms and clinical problems

Problem	Likely Cause	Action
Occlusion alarm	Kinked tubing, blocked SC site, clamp left on	Check line pathway, inspect site, flush gently, replace site if needed
Cloudy solution	Drug precipitation or incompatibility	STOP infusion, discard syringe, prepare new mixture, check compatibility
Infusion complete alarm	Syringe empty	Prepare new syringe within 1h to avoid loss of symptom control
Battery alarm	Low battery	Replace batteries — keep spares at bedside. Most pumps run 24–48h on fresh batteries.
Site induration/redness	Drug irritation or infection	Remove needle, document site condition, re-site at new location
Uncontrolled symptoms despite infusion	Under-dosing, pump error, SC site failure	Assess symptom burden, check pump rate/volume programmed, consider SC PRN rescue dose while reviewing
Rate/volume mismatch	Programming error	Two-nurse independent check required at setup, rate changes, and every 4h

Opioid Availability in GCC

Structural and systemic context

Current Challenges

Morphine as controlled substance: Prescribing restricted to licensed specialist physicians in most GCC states. Community GPs typically cannot prescribe strong opioids.
Limited community access: Strong opioids (morphine, hydromorphone) often unavailable in community pharmacies — patients may need hospital dispensing.
Community palliative care gap: Patients dying at home frequently cannot access adequate opioid analgesia due to prescription and supply chain restrictions.
Tramadol and codeine more readily available but inadequate for severe pain — WHO Step 3 gap.
Improving: Saudi Arabia, UAE, and Qatar have made legislative advances in controlled substance access for palliative care patients (2015–2023 reforms).

Nursing Advocacy Role

Document pain severity rigorously to support specialist referral
Facilitate timely specialist palliative medicine review
Educate families about opioid myths and safety
Liaise with hospital pharmacist for controlled substance supply planning

☪️

Islamic Ethics & Strong Opioids

Religious perspectives in GCC context

Doctrine of Double Effect

Islamic scholars broadly accept opioid use for pain relief in terminal illness. The doctrine of double effect is recognised in Islamic medical ethics: if the primary intention is to relieve suffering, and any potential hastening of death is an unintended side effect, this is permissible (halal).

Scholarly Consensus

Majority position (OIC Islamic Fiqh Council, Saudi Council for Islamic Affairs): opioids for severe pain in terminal illness are permissible
Patient retains the right to pain relief — denial of adequate analgesia may itself be unethical
Addiction concerns in terminal illness context are medically and ethically not applicable

Nursing Application

Engage family and religious advisors early in the discussion
Provide educational materials about intent vs effect
Document family understanding and concerns
Facilitate contact with hospital imam/chaplain if family requests spiritual guidance

Key message to family: "We are giving this medication to relieve suffering and restore dignity — this is consistent with Islamic values of mercy (rahma) and compassion."

⚗️

Ketamine as Analgesic in GCC

Sub-anaesthetic IV infusions for refractory cancer pain

Mechanism & Indications

NMDA receptor antagonist. Prevents central sensitisation. Useful when:

Refractory neuropathic pain not responding to opioids + gabapentinoids
Opioid-induced hyperalgesia (paradoxical pain worsening with opioid escalation)
Morphine dose limitation due to side effects
"Opioid-sparing" — allows morphine dose reduction while maintaining analgesia

Sub-Anaesthetic Dosing

IV infusion: 0.1–0.5 mg/kg/h (much lower than anaesthetic dose)
SC infusion via syringe driver: 50–500 mg/24h
Burst ketamine: 100–500 mg/24h for 3–5 days then reassess

Availability in GCC

Available in GCC ICUs, pain clinics, and specialist palliative care units
Not routinely available in general ward/community palliative care
Classified as controlled substance — specialist prescription required

Nursing Monitoring

Psychomimetic effects: dissociation, hallucinations (reduce with low-dose midazolam or clonidine)
BP and HR monitoring (ketamine is a sympathomimetic — may cause transient BP/HR rise)
Nystagmus (common, not concerning at sub-anaesthetic doses)
Emergence phenomena on stopping infusion — taper gradually

😔

Palliative Sedation

Ethics and practice in GCC

Definition

Intentional reduction of consciousness to relieve refractory symptoms in end-of-life patients, when all other methods have failed. NOT the same as euthanasia.

Indications

Refractory pain (uncontrollable despite maximal analgesia)
Refractory dyspnoea
Terminal agitation/delirium
Intractable nausea/vomiting

GCC Cultural Context

Palliative sedation is ethically and legally complex in GCC. Requires:

Multi-disciplinary team decision (physician + nurse + pharmacist + ethics)
Family/patient informed consent — extensive discussion
Religious consultation recommended (most scholars accept it with correct intent)
Clear documentation of refractory nature of symptoms and intent

Distinction from euthanasia: Palliative sedation aims to relieve suffering — it is not intended to hasten death. Most GCC and Islamic medical bodies accept proportionate palliative sedation for refractory suffering.

GCC Cancer Pain Burden

Epidemiological and clinical context

60–80%

Advanced cancer patients with pain

WHO global estimate; GCC data suggests comparable rates

Late Dx

Stage III-IV at presentation

High proportion of GCC cancer patients present at advanced stage — many with established severe pain

Cultural

Barriers to pain reporting

Stoicism, fear of addiction, family reluctance to report — active nursing assessment essential

Nursing Role in GCC Palliative Care: The nurse is often the primary assessor, advocate, and educator for patients with cancer pain in GCC settings. Proactive pain assessment, family education, and facilitating specialist referral are critical competencies.

Practice Questions

10 MCQs — Advanced Pain & Palliative Symptom Management. Click an option to reveal the answer.

Q1.A patient with advanced dementia scores 2 on Breathing, 1 on Negative Vocalisation, 2 on Facial Expression, 1 on Body Language, and 1 on Consolability on the PAINAD scale. What is the total score and what does it indicate?

Score = 2+1+2+1+1 = 7. PAINAD 7–10 = severe pain. Immediate pharmacological intervention and reassessment within 30 minutes are required. PAINAD ≥4 = significant pain; ≥7 = severe.

Q2.A patient on oral morphine 30mg q4h (total 180mg/24h) is to be converted to a SC syringe driver. What is the correct 24-hour SC morphine dose?

Oral to SC conversion ratio is 2:1. 180mg oral ÷ 2 = 90mg SC/24h. This is because SC/IV morphine is approximately twice as potent as oral morphine (higher bioavailability, bypasses first-pass metabolism).

Q3.Which of the following is the MOST appropriate choice of opioid for a palliative patient with severe cancer pain and an eGFR of 18 ml/min/1.73m²?

Hydromorphone is preferred in significant renal impairment (eGFR <30). Its metabolite (H3G) is less clinically problematic than morphine-6-glucuronide (M6G) which accumulates in renal failure causing sedation and respiratory depression. Codeine and tramadol are also renally cleared and potentially harmful. Fentanyl patch is another acceptable alternative.

Q4.A patient with a fentanyl 50mcg/h patch develops a fever of 39.5°C. A family member has placed a warm compress over the patch site "to help circulation." What is the nurse's priority action?

NEVER apply heat over a fentanyl patch. Heat significantly increases fentanyl absorption (up to 3× higher plasma levels). Fever alone can also increase absorption. Both together risk fatal opioid overdose. Remove heat source immediately, assess for signs of toxicity (pinpoint pupils, drowsiness, RR <8), have naloxone ready, and notify physician. Consider patch removal if toxicity suspected.

Q5.On epidural analgesia assessment, a patient's Bromage score is 2 and blood pressure has dropped from 128/76 to 95/55 mmHg. What is the most appropriate nursing action?

Bromage ≥2 = significant motor block. Combined with hypotension (SBP drop >20%), this indicates excessive sympathetic blockade from the epidural. Reduce or pause infusion, give IV fluid bolus (250–500ml), and notify physician. Ephedrine may be needed. Do NOT increase the rate — this would worsen the situation.

Q6.Which drug should NOT be included in a syringe driver due to incompatibility?

Diazepam should NOT be used in a syringe driver — it is an oily preparation that precipitates in aqueous solution and is incompatible. Prochlorperazine and chlorpromazine are also contraindicated. Midazolam is the benzodiazepine of choice for syringe driver use. Always check with the pharmacist before mixing any drugs.

Q7.A patient with pancreatic cancer has increasing confusion, constipation, and polyuria. Blood tests show corrected calcium of 3.2 mmol/L. Which is the correct initial treatment sequence?

Malignant hypercalcaemia management: First IV saline rehydration (restores GFR and promotes calciuresis), then zoledronic acid 4mg IV over 15 min. Zoledronic acid requires eGFR >35 and adequate rehydration before administration. Furosemide is no longer recommended as a first-line intervention. Onset of bisphosphonate effect is 48–72h — do not expect immediate improvement.

Q8.Pemberton's sign is positive in a patient with known lung cancer. What syndrome does this indicate and what is the immediate management?

Pemberton's sign (facial/neck congestion on arm elevation) is pathognomonic for SVC obstruction. Treatment: dexamethasone 8–16mg IV/oral to reduce tumour oedema, then urgent oncology review for SVC stenting (fastest — relief within 24h) or radiotherapy. Avoid arm/hand IV insertion. Lung cancer is the most common cause.

Q9.A patient on a syringe driver with morphine 30mg + midazolam 10mg + haloperidol 3mg over 24h reports their pain is not controlled. The nurse observes the SC site appears indurated and red. What is the most appropriate action?

SC site induration (hardening) and redness impair drug absorption significantly and may explain loss of symptom control. Remove the needle and re-site immediately. Administer a PRN rescue dose of morphine SC to bridge the gap while the new site is established. Notify the physician of the change in symptom control. Never apply heat (risk of increased/erratic absorption). Inspect SC sites every 4 hours.

Q10.Which statement about strong opioids and Islamic medical ethics is MOST accurate in the GCC palliative care context?

The majority position among Islamic scholars (including the OIC Islamic Fiqh Council) is that opioids for pain relief in terminal illness are permissible. The doctrine of double effect is accepted: if the primary intention is to relieve suffering (not hasten death), the use of opioids is ethically permissible (halal). Denying adequate pain relief to suffering patients may itself be considered unethical. Nurses should facilitate family/religious discussions to address misconceptions.
