A cancer client who weighs 70 kg is scheduled for chemotherapy. A nurse has to administer ondansetron 0.34 mg/kg, 30 minutes prior. What is the dose of ondansetron this client should receive?

23 mg

6.8 mg

23.8 mg

20.59 mg

Answer and Explanation

The Correct Answer is C

To calculate the dose of ondansetron for this client, we need to use the client's weight and the prescribed dose of 0.34 mg/kg.

The formula to calculate the dose is:

Dose (in mg) = Weight (in kg) x Dose (in mg/kg) So, for this client:

Dose (in mg) = 70 kg x 0.34 mg/kg

Dose (in mg) = 23.8 mg (rounded to one decimal place)

Therefore, the client should receive a dose of 23.8 mg of ondansetron, 30 minutes prior to chemotherapy.

Correct Answer is C

Explanation

To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.

Total infusion time = Total volume to be infused / Infusion rate.

In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.

Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.

Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.

A. 0.65 mL/hr B. 9.6 mL/hr C. 10.1 mL/hr D. 14.8 mL/hr

Correct Answer is C

Explanation

We can use the following formula to calculate the infusion rate:

Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg

First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg

125,000 mcg/500 mL = 250 mcg/mL

Now we can plug in the values we have into the formula:

Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr

Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.

Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.
