Question 1 of 5
A nurse is preparing to administer dextromethorphan 30 mg PO. The amount available is dextromethorphan oral liquid 7.5 mg/5mL. How many mL should the nurse administer?
Correct Answer: C
Rationale: The correct answer is C: 20 mL.
To determine this, first calculate how many mL are needed for 30 mg: 30 mg divided by 7.5 mg/5mL = 20 mL. This is the correct dosage based on the concentration of the oral liquid.
Choice A (10 mL) is incorrect because it is too low, not providing the full 30 mg dose.
Choices B (15 mL) and D (25 mL) are incorrect as they do not accurately reflect the calculation based on the concentration of the medication.
