FCPS IMM Anesthesia Regional Anaesthesia & Pain MCQs: High-Yield Practice Questions & Prep

Regional Anaesthesia & Pain is one of the subject blocks in the FCPS IMM Anesthesia QBank. It covers spinal and epidural anaesthesia, nerve blocks, local anaesthetic toxicity and chronic pain. Below is a sample set in the style of the bank, with the reasoning after each answer.

Sample MCQs

1. Acidic drugs such as thiopentone bind mainly to:

• A) Albumin ✅
• B) Alpha-1 acid glycoprotein
• C) Globulin
• D) Haemoglobin

Why: Basic drugs such as lidocaine bind alpha-1 acid glycoprotein.

2. Which is the anesthesia of choice in a daycare dental surgery?

• A) General anesthesia
• B) Spinal anesthesia
• C) Epidural anesthesia
• D) Infiltration anesthesia ✅

Why: This type of anesthesia is preferred for dental / minor procedures.

3. A 35-year-old man is set to undergo a hemorrhoidectomy, and the anaesthetist intends to utilise a saddle block for anaesthesia. Which of the following is the main benefit of employing a saddle block in this procedure?

• A) Provides deep sedation
• B) Longer duration of action
• C) Complete motor blockade.
• D) Rapid recovery of motion ✅

Why: Saddle block is a type of spinal anaesthesia achieved by keeping the patient in a sitting position for 3 to 5 minutes after the injection.

4. During resuscitation, a patient received a 20% intralipid injection. What could have been the most probable diagnosis?

• A) Local anaesthesia toxicity ✅
• B) Asphyxia due to drowning
• C) Electrocution
• D) Pulseless electrical activity

Why: Correct Option A-Local Anaesthesia Toxicity: Intralipid is a lipid emulsion commonly used to treat local anaesthetic systemic toxicity (LAST).

5. A 30-year-old male presents to the clinic with trauma to his lower jaw. He needs stitches on his lower lip near the incisors. Which nerve block will provide adequate anesthesia for suturing the lower lip and nearby gingiva?

• A) Infraorbital nerve block
• B) Mental nerve block ✅
• C) Inferior alveolar nerve block
• D) Supraorbital nerve block

Why: The mental nerve provides sensation to the lower lip, labial mucosa, and gingiva near the incisors and canines , making it the correct choice for anesthesia in this case.

6. Which of the following local anesthetics causes hypertension?

• A) Cocaine ✅
• B) Lignocaine
• C) Bupivacaine
• D) Prilocaine

Why: Cocaine, a potent local anesthetic, has vasoconstrictive properties that can lead to hypertension and cardiovascular complications.

7. Axillary block D. Blocks at the level of cords of the brachial plexus.

• A) 1A,2D,3C,4B
• B) 1C,2A,3D,4B ✅
• C) 1C,2A,3B,4D
• D) 1B,2C,3A,4D

Why: Greater auricular nerve block is preferred for pinna repair because it provides effective analgesia to the ear and surrounding areas, reducing the need for perioperative opioids.

8. Anesthetist decides to administer Lignocaine with adrenaline for epidural analgesia. Choose the correct pair of concentration of Lignocaine and the concentration ratio when used with adrenaline.

• A) 1% - 1:100,000
• B) 1% - 1:200,000 ✅
• C) 5% - 1:200,000
• D) 5% - 1:100,000

Why: Ideal concentration of Lignocaine when given epidurally is 1-2% and the concentration ratio with Adrenaline for Lignocaine/Bupivacaine/Prilocaine is 1:200,000 .

9. All among the following are true about adding Adrenaline with Lignocaine except:

• A) Increases the duration of action
• B) Decreases blood loss
• C) Contraindicated in patients with cardiovascular disease
• D) Increases the rate of systemic absorption ✅

Why: Adding Adrenaline (Epinephrine) with Lignocaine decreases the rate of systemic absorption of Lignocaine and thereby decreases the effects of systemic toxicity of Lignocaine.

10. Which nerve fibres are blocked first by local anaesthetic?

• A) Small myelinated B and A-delta fibres (autonomic and pain) ✅
• B) Large A-alpha fibres
• C) Large A-beta fibres
• D) Sensory touch fibres first

Why: Autonomic then pain then touch then motor are blocked in order.

How to Study This Block

• Know the dermatomal levels and the landmarks for spinal and epidural placement.
• Learn the signs and treatment of local anaesthetic systemic toxicity.
• Revise the contraindications to neuraxial blocks.

Each subject in the QBank can be filtered on its own, so you can drill regional anaesthesia & pain until your accuracy is stable. Confirm the exam format and syllabus against the current CPSP guidelines.

Frequently Asked Questions

Is ultrasound-guided technique tested?

The questions focus on anatomy, drugs and complications rather than machine settings.

Does it include chronic pain?

Yes, with the common pain syndromes and analgesic ladders.
