Extract:


Question 1 of 5

A nurse is preparing to administer sulfadiazine 150mg/kg PO to divide equally every 6 hr to an adolescent who weighs 88 lb. Available is sulfadiazine 500 mg/tab. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: B

Rationale:
To calculate the dose, first convert the weight from lb to kg: 88 lb / 2.2 = 40 kg.
Then calculate the total dose: 150mg/kg x 40 kg = 6000 mg. Next, determine the dose per administration by dividing the total dose by the number of administrations per day: 6000 mg / 4 doses = 1500 mg. Finally, calculate the number of tablets needed: 1500 mg / 500 mg/tab = 3 tablets per dose.
Therefore, the correct answer is B: 3 tablets.
Choice A is incorrect because it does not provide the required dose.

Choices C and D are incorrect as they exceed the calculated dose.
