A nurse is preparing to administer levothyroxine 100 mcg PO daily. Available is levothyroxine 50 mcg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
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, and X is the amount to administer.
In this case, D is 100 mcg, H is 50 mcg, Q is 1 tablet, and X is unknown. Plugging in the values, we get:
100/50 x 1 = X
2 x 1 = X
X = 2
