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 mL"]
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 ["1.9 mL"]
Explanation
To calculate the number of mL the nurse should administer, you need to divide the dose of isoniazid (187 mg) by the concentration of the isoniazid injection (100 mg/mL). This gives you 187 mg / (100 mg/mL) =
1.87 mL. When rounded to the nearest tenth, this becomes 1.9 mL. So, the nurse should administer 1.9 mL of isoniazid injection.
Correct Answer is ["200"]
Explanation
To convert the client's weight from kilograms to pounds, you need to multiply the weight in kilograms by the conversion factor of 2.2 lb/kg. So, 91 kg * 2.2 lb/kg = 200.2 lb. When rounded to the nearest whole number, this becomes 200 lb.
