Question 1 of 5
A nurse is preparing to administer gentamicin 2 mg/kg IV to a client who weighs 220 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number.)
Correct Answer: A
Rationale: The correct answer is A: 200 mg.
To calculate the dose, first convert the client's weight from pounds to kilograms: 220 lb ÷ 2.2 = 100 kg.
Then, multiply the weight in kg by the dose prescribed (2 mg/kg): 100 kg × 2 mg/kg = 200 mg. This is the correct dosage based on the client's weight.
Choice B (180 mg) is incorrect as it does not account for the correct weight-based calculation.
Choices C and D (400 mg and 440 mg) are incorrect as they are significantly higher doses that do not align with the weight-based dosing calculation.
