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?

A.

23 mg

B.

6.8 mg

C.

23.8 mg

D.

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 B

Explanation

Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)

Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)

Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL

So, the nurse should administer 64 mL to the patient.

The correct answer is B. 64 mL.

The correct answer is B. 64 mL.

Correct Answer is B

Explanation

We can use the following formula to calculate the infusion time:

Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)

First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:

19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:

Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours

To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:

9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)

Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).
