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

Explanation
A. Colchicine is specific for gout and does not treat osteoarthritis.
B. Colchicine works by reducing inflammation and pain during a gout flare-up, but it does not prevent future attacks or lower the level of uric acid in the blood. Therefore, it is not a long-term solution for gout.
C. Colchicine does not affect the formation of uric acid crystals, which are the cause of gout. It only reduces the inflammation caused by the crystals in the joints.
D. Colchicine may take several days to weeks to reduce the swelling and pain of a gout attack, depending on the severity and duration of the flare-up. It is not a fast- acting medication.
