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
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 B
Explanation
To calculate the infusion rate in mL/hr, we need to divide the total volume to be infused by the time for infusion and convert the units appropriately.
First, we need to convert the time of infusion from hours to minutes, since most IV pumps use minutes as the time unit.
2 hours x 60 minutes/hour = 120 minutes Next, we can calculate the infusion rate:
500 mL ÷ 120 minutes = 4.17 mL/minute
To convert mL/minute to mL/hour, we multiply by 60:
4.17 mL/minute x 60 minutes/hour = 250 mL/hour
Therefore, the correct answer is B. 250 mL/hr. The nurse should set the IV pump to deliver the LR infusion at a rate of 250 mL/hr to infuse 500 mL over 2 hours.
Correct Answer is B
Explanation
We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.
275/X = 500/2.
Cross-multiplying, we get:. 500X = 275 x 2.
X = (275 x 2)/500. X = 1.1 mL.
Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.
