A nurse is preparing to administer digoxin 0.375 mg PO daily. 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.)

Determine the desired dosage: The nurse needs to administer 0.375 mg of digoxin. Determine the volume per dose: The digoxin elixir contains 0.05 mg per 1 mL. The nurse needs to administer 0.375 mg per dose. To find the volume per dose, we can set up a proportion: 0.05 mg / 1 mL = 0.375 mg / x mL Cross-multiplying gives us: 0.05x = 0.375 Dividing both sides by 0.05, we get: x = 7.5 mL
