A nurse is caring for a patient who has sepsis.

The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus.

How many mL/hr should the nurse set the IV pump to deliver?

Answer and Explanation

The Correct Answer is ["125"]

Step 1 is to understand the question. The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus. We need to calculate how many mL/hr the nurse should set the IV pump to deliver.

Step 2 is to calculate the rate. The total volume to be administered is 250 mL and the time for administration is 2 hours. So, the rate is 250 mL ÷ 2 hours = 125 mL/hr.

Correct Answer is ["24"]

Explanation

Step 1 is: To find out how many mL/hr the IV pump should be set to deliver, we need to set up a proportion with the prescribed units of heparin on one side and the available units of heparin on the other side. So, the calculation is: (1,200 units/hr ÷ 25,000 units) × 500 mL = 24 mL/hr.

Therefore, the IV pump should be set to deliver 24 mL/hr.

A. To remove gastric acid that might cause dyspepsia B. To identify delayed gastric emptying C. To determine the patient’s electrolyte balance D. To confirm the placement of the NG tube

Correct Answer is B

Explanation

Choice A rationale

While gastric acid can cause dyspepsia, measuring gastric residual is not primarily done to remove gastric acid.

Choice B rationale

Measuring gastric residual is primarily done to identify delayed gastric emptying. This is important because delayed gastric emptying can lead to complications such as aspiration pneumonia.

Choice C rationale

Gastric residual does not directly determine the patient’s electrolyte balance.

Choice D rationale

While confirming the placement of the NG tube is important, it is not the primary purpose of measuring gastric residual.
