Infant prescribed levothyroxine 0.175 mg PO once a day, available as 88 mcg/tablet
Question 1 of 5
A nurse is preparing to administer levothyroxine 0.175 mg PO once a day. The amount available is levothyroxine 88 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: B
Rationale: The correct answer is B: 2 tablets.
To calculate the number of tablets needed, convert 0.175 mg to mcg (175 mcg).
Then, divide the total mcg needed (175 mcg) by the mcg per tablet (88 mcg). 175 mcg / 88 mcg per tablet = 1.988. Since we need to round to the nearest whole number, the nurse should administer 2 tablets per dose.
A: 1 tablet is incorrect because 1 tablet only provides 88 mcg, which is less than the required 175 mcg.
C: 3 tablets is incorrect because 3 tablets would provide 3 x 88 mcg = 264 mcg, exceeding the required 175 mcg.
D: 4 tablets is incorrect because 4 tablets would provide 4 x 88 mcg = 352 mcg, significantly exceeding the required 175 mcg.
