Question 2 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: 88 lb ÷ 2.2 = 40 kg; 150 mg/kg × 40 kg = 6000 mg/day; 6000 mg ÷ 4 doses = 1500 mg/dose; 1500 mg ÷ 500 mg/tab = 3 tablets.
Question 3 of 5
A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr. The client's weight is 121 lb. Available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: 121 lb ÷ 2.2 = 55 kg; 55 kg × 1 mg/kg = 55 mg; 60 mg/0.6 mL = 100 mg/mL; 55 mg ÷ 100 mg/mL = 0.55 mL, rounded to 0.6 mL.
