Pharmacy Technician Certification Exam Practice Questions Practice Question
A physician has ordered a total daily dose of 0.5 mg of a medication to be divided into four equal doses. How much medication should each dose contain,in mcg?
Correct Answer: C
Rationale: To determine the amount of medication per dose, first convert the total daily dose from milligrams to micrograms. Since 1 mg equals 1,000 mcg, a total of 0.5 mg translates to 500 mcg. Dividing this total by the four doses yields 500 mcg ÷ 4 = 125 mcg per dose.
Option A (0.125 mcg) is too low, as it miscalculates the conversion and division. Option B (12.5 mcg) underestimates the required dose significantly. Option D (200 mcg) exceeds the calculated amount, indicating a misunderstanding of the division process. Only option C accurately reflects the correct dosage per administration.
