Question

a nurse is preparing to administer amikacin 7 mg/kg/day im to a client who weighs 165 pounds. available is amikacin 250 mg/ml solution for injection. how many ml should the nurse administer per dose? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert pounds to kilograms

Since 1 pound = 0.453592 kg, for a 165 - pound client, the weight in kg is $165\times0.453592\approx74.8427$ kg.

Step2: Calculate total daily dose in mg

The dosage is 7 mg/kg/day, so the total daily dose is $7\times74.8427\approx523.8989$ mg.

Step3: Calculate volume in mL

Using the formula $Volume=\frac{Dose}{Concentration}$, where the concentration is 250 mg/mL. So $Volume = \frac{523.8989}{250}\approx2.1$ mL.

Answer:

2.1
