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

Answer and Explanation

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

The ordered dose is 400 mcg, which is equal to 0.4 mg..

The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.

0.4 mg ÷ 0.1 mg/mL = 4 mL.

Therefore, the nurse should administer 4 mL of atropine sulfate.

A. 0.14 mL B. 0.136 mL C. 136 mL D. 300 mL

Correct Answer is B

Explanation

To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.

30 lb / 2.205 = 13.61 kg.

Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.

Dose (in mcg) = 136.1 mcg.

Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.

1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.

Cross-multiplying, we get:. 1X = 136.1 x 1.

X = 136.1 mL.

Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
