A nurse is infusing an IV fluid at 40 mL/hr, and 376 mL of fluid remains in the bag. The current time is 19:30. What is the infusion time in hr and min?

9 hr and 15 min

9 hr and 24 min

9 hr and 30 min

9 hr and 40 min

Answer and Explanation

The Correct Answer is B

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).

Correct Answer is B

Explanation

We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.

275/X = 500/2.

Cross-multiplying, we get:. 500X = 275 x 2.

X = (275 x 2)/500. X = 1.1 mL.

Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.

A. 250 mg B. 500 mg C. 1000 mg D. 1500 mg

Correct Answer is C

Explanation

To calculate the total amount of medication the client should receive, multiply the volume of the medication by its concentration:

500 mL x 2 mg/mL = 1000 mg

Therefore, the client should receive 1000 mg of the medication.
