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
The correct answer is choice B. 2 bottles. To find the number of bottles required, use the formula: (dose x duration) / (bottle size x tablet strength). In this case, (600 mg/day x 7 days) / (7 tablets/bottle x 300 mg/tablet) = 2 bottles.
Correct Answer is B
Explanation
The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:
Amount of solution = Amount of medication needed / Concentration of medication in the solution.
In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:
Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL
Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.
