Acute Pain Management MCQ Quiz

Welcome to the Acute Pain Management MCQ Quiz, specifically designed for MBBS students. This assessment will test your understanding of the essential principles and practices in managing acute pain, a fundamental skill in clinical medicine. The quiz covers a range of topics including the WHO analgesic ladder, pharmacology of common analgesics like opioids and NSAIDs, regional anesthesia techniques, patient-controlled analgesia (PCA), and the management of specific pain scenarios. Each of the 25 questions is crafted to reflect real-world clinical situations and core syllabus knowledge. After completing the quiz, you can submit your answers to see your score and review the correct responses. For your future reference and study, an option to download all questions and their correct answers in a PDF format is also available.

Q1: What is the first-line analgesic for mild acute pain according to the WHO analgesic ladder?

Non-opioids (e.g., Paracetamol, NSAIDs)

Weak opioids (e.g., Codeine, Tramadol)

Strong opioids (e.g., Morphine, Fentanyl)

Adjuvant therapies (e.g., Gabapentin)

Flumazenil

Naloxone

N-acetylcysteine

Atropine

Q3: What is the primary mechanism of action of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?

Inhibition of cyclooxygenase (COX) enzymes

Agonism at mu-opioid receptors

Blocking of sodium channels

Inhibition of substance P

Naloxone

N-acetylcysteine

Glucagon

Fomepizole

Q6: A 45-year-old post-operative patient describes his pain as “the worst imaginable.” Which score on the Numerical Rating Scale (NRS) does this correspond to?

Q7: Which of the following is a serious but rare complication of epidural analgesia?

Pruritus

Nausea and vomiting

Epidural hematoma

Urinary retention

Q8: The concept of multimodal analgesia aims to:

Rely solely on opioids for severe pain.

Use only non-pharmacological methods.

Target different pain pathways to reduce opioid consumption and side effects.

Administer one high-dose analgesic to block all pain.

Q9: Tramadol provides analgesia through which two primary mechanisms?

Strong mu-opioid agonism and COX-2 inhibition

NMDA receptor antagonism and sodium channel blockade

Weak mu-opioid receptor agonism and inhibition of serotonin/norepinephrine reuptake

Kappa-opioid agonism and calcium channel blockade

Q10: Which anaesthetic agent, when used in sub-anaesthetic doses, is effective for acute pain, particularly neuropathic or opioid-tolerant pain?

Propofol

Ketamine

Sevoflurane

Thiopental

Q11: A patient with a history of peptic ulcer disease and acute kidney injury requires analgesia for a fracture. Which class of drugs is relatively contraindicated?

Opioids

Paracetamol

NSAIDs

Local Anesthetics

Q12: What is the most common side effect associated with the use of opioid analgesics?

Respiratory depression

Constipation

Nausea

Sedation

Q13: For an ankle fracture, which regional nerve block would provide the most effective analgesia?

Femoral nerve block

Popliteal sciatic nerve block

Interscalene block

Axillary block

Q14: The administration of analgesics before a painful stimulus (e.g., surgical incision) is known as:

Reactive analgesia

Rescue analgesia

Pre-emptive analgesia

Multimodal analgesia

Q15: Compared to non-selective NSAIDs, selective COX-2 inhibitors (e.g., celecoxib) have a lower risk of:

Cardiovascular events

Renal dysfunction

Bronchospasm in asthmatics

Gastrointestinal bleeding

Q16: What is the cornerstone of management for acute pain in a vaso-occlusive sickle cell crisis?

High-dose NSAIDs

Aggressive hydration and opioid analgesics

Blood transfusion

Corticosteroids

Q17: Codeine is a prodrug that is metabolized into its active form, morphine, by which cytochrome P450 enzyme?

CYP3A4

CYP2D6

CYP2C9

CYP1A2

Q18: Gabapentin and pregabalin are primarily used in acute pain management for:

Providing immediate, potent analgesia for severe pain.

Reducing inflammation at the site of injury.

Treating opioid-induced constipation.

Preventing the transition to chronic post-surgical pain.

Q19: A patient receiving a continuous peripheral nerve block suddenly develops tinnitus, a metallic taste, and perioral numbness. These are early signs of:

Anaphylactic reaction

Opioid overdose

Local anesthetic systemic toxicity (LAST)

Hyperglycemia

Q20: Opioid use in the post-operative period is a major risk factor for which gastrointestinal complication?

Gastritis

Post-operative ileus

Pancreatitis

Cholecystitis

Q21: Which of the following is an example of a non-pharmacological intervention for acute pain management?

Administration of IV morphine

A peripheral nerve block

Application of ice packs

Prescribing oral celecoxib

Q22: A patient is being switched from oral morphine to intravenous morphine. The dose of intravenous morphine will be approximately:

The same as the oral dose

Double the oral dose

One-third of the oral dose

One-tenth of the oral dose

Q23: A patient on a regular opioid regimen for post-operative pain experiences a sudden, severe flare-up of pain. This is best managed with:

Increasing the dose of the long-acting opioid

Adding an NSAID

A short-acting “rescue” dose of an opioid

Administering naloxone

Q24: Besides its analgesic and anti-inflammatory effects, what unique property does low-dose aspirin possess that is not shared by other NSAIDs?

Reversible COX inhibition

Irreversible inhibition of platelet aggregation

Selective COX-2 inhibition

Potent antipyretic effect

Q25: For an average adult with normal liver function, what is the maximum recommended daily dose of paracetamol (acetaminophen)?

1 gram

2 grams

4 grams

6 grams
