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 ["10"]

Explanation

To calculate the volume in milliliters (mL) of amoxicillin oral suspension needed to administer 775 mg, you can use the following formula:

Volume (mL) = (Desired dose in mg / Concentration in mg/mL)

Given:

  • Desired dose = 775 mg
  • Concentration = 400 mg/5 mL

First, calculate the concentration in mg/mL by dividing 400 mg by 5 mL:

Concentration = 400 mg / 5 mL = 80 mg/mL

Now, use the formula to calculate the volume in mL:

Volume (mL) = (775 mg / 80 mg/mL)

Volume (mL) ≈ 9.69 mL

Rounded to the nearest whole number, the nurse should administer approximately 10 mL of amoxicillin oral suspension to provide a dose of 775 mg.

Correct Answer is ["4.5"]

Explanation

To calculate the mL of ondansetron 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 = 132 lb / 2.2 ≈ 60 kg

Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 60 kg × 0.15 mg/kg = 9 mg

Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 2 mg / 1 mL = 2 mg/mL

Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 9 mg / 2 mg/mL = 4.5 mL

Round the answer to the nearest tenth:
The nurse should administer 4.5 mL of ondansetron.
