Question

Dose of chloroquine at 4 to 8 years is -

• A. 150 mg
• B. 300 mg
• C. 450 mg
• D. 600 mg

Hint:

Two 150 mg base tablets are given for the 5 to 8 year age band.

Answer 1

The Correct Option is B

Step 1: Chloroquine for malaria is dosed by age using 150 mg base tablets. For the 5 to 8 year age group the schedule gives 2 tablets on day 1 and day 2.

Step 2: Two tablets of 150 mg base equal 300 mg of chloroquine base, so option b is correct.

Step 3: 150 mg (option a) is the dose for younger children around 1 to 4 years. Higher totals of 450 mg or 600 mg (options c and d) correspond to older children and adults of 9 years and above, not to this age band.
