Practice Question
A nurse is preparing to administer digoxin 8 mcg/kg/day PO to divide equally every 12 hr for a preschooler who weighs 33 lb. Available is digoxin elixir 0.05 mg/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 use a trailing zero.)
Answer Choices:
Correct Answer:
1.2
Rationale:
Convert weight to kg:
33÷2.2=15 kg
Calculate total daily dose:
8×15=120 mcg
Divide by two doses per day:
120÷2=60
mcg per dose
120÷2=60 mcg per dose
Convert mcg to mg:
60 mcg=0.06 mg
Convert to mL:
0.06/0.05=1.2mL
