Question 1 of 5
A nurse is preparing to administer levothyroxine 0.175 mg PO once a day. The amount available is levothyroxine 8 mcg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: D
Rationale:
To calculate the number of tablets needed, convert 0.175 mg to mcg (0.175 mg x 1000 = 175 mcg). Divide the total mcg needed by the mcg per tablet (175 mcg รท 8 mcg/tablet = 21.875). Rounding up to the nearest whole number, the nurse should administer 22 tablets per dose, making choice D the correct answer.
Choice A is incorrect as it is too low.
Choice B is incorrect as it does not account for the conversion and rounding.
Choice C is incorrect as it is too high.
