A nurse is preparing to administer gentamicin 1 mg/kg IM to a client who weighs 154 lb. Available is gentamicin solution 40 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 ["1.8"]
Step 1: Convert pounds to kilograms.
154 lb * (1 kg / 2.20462 lb) = 70 kg
Step 2: Calculate the total dose of gentamicin.
1 mg/kg * 70 kg = 70 mg
Step 3: Calculate the volume of gentamicin solution to administer.
70 mg / 40 mg/mL = 1.75 mL
Therefore, the nurse should administer 1.8 mL of gentamicin solution.

Correct Answer is ["0.5"]
Explanation
To calculate the volume to be administered, the nurse should first divide the prescribed dose (100 mg) by the concentration of the available medication (200 mg/5 mL): 100 mg / (200 mg/5 mL) = 2.5 mL. Since there are 5 mL in a teaspoon, the parent should administer 2.5 mL / 5 mL/teaspoon = 0.5 teaspoons per dose.
Correct Answer is ["2"]
Explanation
To calculate the volume to be administered, the nurse should divide the prescribed dose (200 mg) by the
concentration of the available medication (300 mg/3 mL): 200 mg / (300 mg/3 mL) = 2 mL.
