A nurse is preparing to administer hydrochlorothiazide 25 mg PO every 8 hr. The amount available is hydrochlorothiazide 50 mg/tab. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To answer this question, the nurse needs to use the formula D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity of the dose form, and X is the amount to administer. In this case, D is 25 mg, H is 50 mg, Q is 1 tablet, and X is unknown. Plugging these values into the formula, we get:
25/50 x 1 = X
0.5 x 1 = X
X = 0.5
