Sample SBA Practice Questions

Sample Question 1 (Paper B)

A patient suddenly develops acute anaphylaxis following LA injection. What is the immediate first-line drug and dose?

  1. IV adrenaline 0.5 mg (1:10,000) into a large forearm vein
  2. IM adrenaline 0.3 mg (1:10,000) into the anterolateral thigh
  3. IM adrenaline 0.5 mg (1:1000) into the anterolateral thigh
  4. IM chlorphenamine 10 mg into the deltoid muscle

Correct Answer: IM adrenaline 0.5 mg (1:1000) into the anterolateral thigh
Explanation: Anaphylaxis first-line treatment is immediate IM Adrenaline 0.5mg (1:1000) into anterolateral thigh.
Clinical Pearl: IM Adrenaline 0.5mg 1:1000 is first-line emergency drug for acute anaphylaxis.

Sample Question 2 (Paper B)

A patient with a history of angina experiences crushing retrosternal chest pain during treatment. What is the initial drug of choice?

  1. High-flow oxygen, 15 litres per minute
  2. Chewable aspirin tablet, 300 milligrams
  3. Sublingual glyceryl trinitrate spray, 400 micrograms
  4. Sublingual nifedipine capsule, 5 milligrams

Correct Answer: Sublingual glyceryl trinitrate spray, 400 micrograms
Explanation: Sublingual GTN spray (1-2 puffs) dilates coronary arteries and relieves angina pectoris symptoms.
Clinical Pearl: Sublingual GTN spray 400mcg (1-2 puffs) is first-line for acute angina pectoris.

Sample Question 3 (Paper B)

An asthmatic patient suffers an acute bronchospasm attack in the dental chair. Which inhaler should be administered immediately?

  1. Beclometasone (brown inhaler) 200 mcg/puff, up to 4 puffs via spacer
  2. Salmeterol (green inhaler) 25 mcg/puff, up to 2 puffs via spacer
  3. Ipratropium bromide (grey inhaler) 20 mcg/puff, up to 4 puffs via spacer
  4. Salbutamol (blue inhaler) 100 mcg/puff, up to 10 puffs via spacer

Correct Answer: Salbutamol (blue inhaler) 100 mcg/puff, up to 10 puffs via spacer
Explanation: Salbutamol is a short-acting beta-2 agonist administered via spacer (up to 10 puffs) during acute asthma attacks.
Clinical Pearl: Acute asthma bronchospasm is treated immediately with Salbutamol inhaler via spacer.
