A nurse is preparing to administer digoxin 0.375 mg PO dally. Available is digoxin elixir 0.05 mg/mL. How many ml. should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
1. Determine the volume based on concentration and dosage:
Digoxin dosage (mg): 0.375 mg
Digoxin concentration (mg/mL): 0.05 mg/mL (from the available elixir)
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 0.375 mg / 0.05 mg/mL
2. Round the answer to the nearest tenth:
The calculated volume is 7.5 mL. Rounding to the nearest tenth:
Volume (mL) = 7.5 mL (rounded)
Therefore, the nurse should administer 7.5 mL of digoxin elixir.
