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.)
The Correct Answer is ["7.5"]
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

Correct Answer is ["0.6"]
Explanation
Determine the desired dosage:
The nurse needs to administer 3 mg of haloperidol.
Determine the volume per dose:
The haloperidol injection contains 5 mg per 1 mL.
The nurse needs to administer 3 mg per dose.
To find the volume per dose:
5 mg / 1 mL = 3 mg / x mL
Cross-multiplying gives us:
5x = 3
Dividing both sides by 5, we get:
x = 0.6 mL
Correct Answer is ["1.6"]
Explanation
Determine the desired dosage:
The nurse needs to administer 480 mcg of filgrastim.
Determine the volume per dose:
The filgrastim injection contains 300 mcg per 1 mL.
The nurse needs to administer 480 mcg per dose.
To find the volume per dose:
300 mcg / 1 mL = 480 mcg / x mL
Cross-multiplying gives us:
300x = 480
Dividing both sides by 300, we get:
x = 1.6 mL
