A nurse is preparing to administer sulfadiazine 150mg/kg PO to divide equally every 6 hr to an adolescent who weighs 88 Ib.
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.).
1 tablet.
3 tablets.
4 tablets.
8 tablets.
The Correct Answer is B
Step 1: Convert weight from lb to kg.
88 lb ÷ 2.2 = 40 kg
Step 2: Calculate total daily dose in mg.
150 mg/kg × 40 kg = 6000 mg
Step 3: Calculate dose per administration (every 6 hr).
6000 mg ÷ 4 = 1500 mg
Step 4: Calculate number of tablets per dose.
1500 mg ÷ 500 mg/tab = 3 tablets
Answer:
3 tablets per dose.
