A nurse is preparing to administer fluoxetine 40 mg PO daily. The available medication is fluoxetine 20 mg/mL. How many mL should the nurse administer? How many mL of fluoxetine should the nurse administer?
Correct answer
B
Rationale
To calculate the mL of fluoxetine to administer, use the formula: desired dose (40 mg) / stock dose (20 mg/mL) = mL to administer. Therefore, 40 mg / 20 mg/mL = 2 mL. This is why choice B (2 mL) is correct. Choice A (1 mL) is incorrect as it does not provide the full dose. Choices C (3 mL) and D (4 mL) are incorrect as they exceed the required dose.
