Passage / Scenario
A child weighs 12kg. The reference safe dose is 7-9mg/kg/day.A child is ordered Phenytoin 75 mg po twice a day. What is the minimum dose this child should receive per day?
Correct answer
A
Rationale
The correct answer is A (84). To calculate the minimum dose per day, we add up the total daily dose prescribed (75 mg x 2 = 150 mg) and then round up to the nearest practical dose increment, which in this case is 84 mg (since we cannot give half of 75 mg). Choices B-G are incorrect as they do not follow the correct calculation method or do not round up appropriately.
