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 ["20.3"]

Explanation

To calculate the amount of acetaminophen liquid to administer, you can use the following formula:

Amount (mL) = (Desired Dose in mg) / (Concentration in mg/mL)

Amount (mL) = 650 mg / (160 mg/5 mL) = 20.31 mL

Rounded to the nearest tenth, the nurse should administer approximately 20.3 mL of acetaminophen liquid.

Correct Answer is ["5"]

Explanation

To calculate the volume of megestrol oral suspension (in milliliters, mL) that the nurse should administer, use the following formula:

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

In this case, the dose is 200 mg of megestrol, and the concentration of the oral suspension is 40 mg/mL.

Volume (mL) = 200 mg / 40 mg/mL

Volume (mL) = 5 mL

The nurse should administer 5 mL of megestrol oral suspension to the client.
