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 C
Explanation
We need to calculate the patient's BSA using one of the available formulas. The most widely used formula is the Du Bois formula, which is:.
BSA = 0.007184 × W^0.425 × H^0.725.
where W is weight in kg and H is height in cm.. Plugging in the patient's weight and height, we get:. BSA = 0.007184 × 94.5^0.425 × 185^0.725
BSA = 2.15 m².
Now, we can use the physician's order to find the daily dose and the total dose of Platinol for this patient. The daily dose is:.
Daily dose = 20 mg/m²/day × BSA Daily dose = 20 mg/m²/day × 2.15 m² Daily dose = 43 mg/day.
The total dose for 5 days is:.
Total dose = Daily dose × Number of days Total dose = 43 mg/day × 5 days
Total dose = 215 mg.
Therefore, the patient's dose of Platinol would be 215 mg in total, or 43 mg per day for 5 days.
Correct Answer is D
Explanation
The toddler is ordered to receive 25 mg/kg of Principen IV over 30 minutes. The toddler weighs 22 lb, which is equivalent to 10 kg. To calculate the total amount of Principen the toddler should receive, multiply the weight by the dosage:
10 kg x 25 mg/kg = 250 mg
The Principen dose arrives from the pharmacy prepared in 50 mL of IV solution, which means there is 250 mg of Principen in 50 mL of solution. To calculate how many milliliters per hour the nurse should administer, we can use the following formula:
50 mL / 0.5 hour = X mL per hour X = 100 mL per hour
Therefore, the nurse should administer 100 mL of Principen per hour to the toddler.
