A nurse is preparing to administer gentamicin 5 mg/kg via intermittent IV bolus to a client who weighs 210 lb. The amount available is gentamicin 10 mg/mL. How many ml, should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["48"]

To calculate how many milliliters (ml) of gentamicin to administer, follow these steps:
    Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2 
    Weight in kilograms = 210 lb / 2.2 Weight in kilograms ≈ 95.45 kg
    
    Determine the dose based on the weight: Dose = 5 mg/kg × Weight in kilograms Dose = 5 mg/kg × 95.45 kg Dose ≈ 477.25 mg
    
    Check the concentration of the available gentamicin: Concentration = 10 mg/mL
    
    Calculate the volume (ml) to administer: Volume (ml) = Dose (mg) / Concentration (mg/ml) Volume (ml) = 477.25 mg / 10 mg/ml Volume (ml) ≈ 47.73 ml
    
Rounded to the nearest whole number, the nurse should administer approximately 48 ml of gentamicin.

Correct Answer is ["68"]

Explanation

To calculate the mL of acetaminophen to administer, follow these steps:
Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 99 lb / 2.2 ≈ 45 kg

Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 45 kg × 15 mg/kg = 675 mg

Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 1,000 mg / 100 mL = 10 mg/mL

Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 675 mg / 10 mg/mL = 67.5 mL

Round the answer to the nearest whole number:
The nurse should administer 68 mL of acetaminophen
