A nurse is preparing to administer ondansetron 0.15 mg/kg IV to a client who weighs 132 lb. Available is ondansetron 2 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.)

Answer and Explanation

The Correct Answer is ["4.5"]

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.

Correct Answer is ["6"]

Explanation

To calculate the volume (mL) needed to administer 300 mg of amiodarone using a concentration of 50 mg/mL, you can use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

In this case, the dose is 300 mg, and the concentration is 50 mg/mL:

Volume (mL) = 300 mg / 50 mg/mL = 6 mL

So, the nurse should administer 6 mL of amiodarone.

Correct Answer is ["48"]

Explanation

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.
