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 A
Explanation
The infusion was started at 06:57 and completed at 15:45, which is a total time of: 15 hours and 45 minutes - 6 hours and 57 minutes = 8 hours and 48 minutes
To calculate the flow rate, we need to know the total amount of fluid infused and divide it by the total time of infusion:
1 L = 1000 mL
Total time of infusion = 8 hours and 48 minutes = 528 minutes Flow rate = Total amount of fluid infused / Total time of infusion Flow rate = 1000 mL / 528 minutes
Flow rate = 1.89394 mL/min
To convert mL/min to mL/hr, we multiply by 60:
Flow rate = 1.89394 mL/min x 60 min/hr Flow rate = 113.6364 mL/hr
Therefore, the flow rate of infusion in this situation is approximately 114 mL/hr, which corresponds to option A.
Correct Answer is D
Explanation
Choice A:One tablet contains 500 mg, which is far below the prescribed dose of 15 g/day. Administering one tablet daily would only provide 500 mg/day, which is insufficient.
Choice B:Each dose of 2 tablets provides 1000 mg (1 g), and giving this dose three times daily totals 3000 mg (3 g/day). This is significantly less than the required 15 g/day.
Choice C:Half a tablet would provide 250 mg/day, which is far below the prescribed dose of 15 g/day. This is inadequate and does not meet the prescription requirements.
Choice D:
The provider ordered 15 g/day of niacinamide. 15g=15,000mg
Tablet strength: Each tablet contains 500 mg. 15,000mg÷500mg=30tablets/day
Dosing schedule: The order is for a daily dose, divided evenly across the day. If given every 8 hours (3 doses/day): 30tablets÷3doses=10 tablets/dose
