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).

A. 23 mg B. 6.8 mg C. 23.8 mg D. 20.59 mg

Correct Answer is C

Explanation

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.
