A patient needs 100 mg of a psychotropic medication given PO TID. Tablets are supplied at a strength of 50 mg per tablet. How many tablets should the patient take per dose?

A. Taking only one tablet would provide 50 mg, which is only half of the required 100 mg dose. B. This would provide 200 mg per dose, which is double the prescribed amount and could lead to toxicity. C. This is a common "distractor" error where a student sees "TID" (3 times a day) and assumes the patient takes 3 tablets at once. This would provide 150 X mg. D. Step 1: Use the formula- Number of tablets = Desired dose ÷ Dose available. Step 2: Insert known values (Desired dose = 100 mg, Dose available = 50 mg/tablet). Number of tablets = 100 ÷ 50 = 2.
