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 answer, we can use the following formula:.
(mg of drug required / total mg in vial) x total volume in vial = mL to administer. First, let's convert the dose from mg to g:.
80 mg = 0.08 g.
Next, let's plug in the values:. (0.08 g / 1 g) x 8 mL = 0.64 mL.
Therefore, the nurse should administer 0.64 mL of Solu-Medrol.
Correct Answer is D
Explanation
First, we need to calculate the total dose of esmolol required per minute: Total dose = Weight x Dose x 60 minutes
Total dose = 65 kg x 200 mcg/kg/min x 60 minutes Total dose = 780,000 mcg/min
Next, we need to convert the dose to milligrams (mg):
780,000 mcg/min = 780 mg/min
The concentration of the esmolol solution is 2,500 mg in 250 mL or 10 mg/mL. To deliver 780 mg/min at a concentration of 10 mg/mL, we need to infuse: Infusion rate = Total dose / Concentration
Infusion rate = 780 mg/min / 10 mg/mL Infusion rate = 78 mL/min
Rounding to the nearest whole number, the answer is D. 78 mL/hr.
Therefore, the nurse should calculate an infusion rate of 78 mL/hr to deliver the required dose of esmolol to the patient.
