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 ["31"]

Explanation

Step 1: Calculate the total volume to be infused. Total volume = 250 mL.

Step 2: Calculate the total time for the infusion in minutes. Total time = 2 hours × 60 minutes/hour = 120 minutes.

Step 3: Calculate the flow rate in mL/min. Flow rate = Total volume ÷ Total time = 250 mL ÷ 120 min = 2.08 mL/min.

Step 4: Calculate the flow rate in drops/min. Flow rate = 2.08 mL/min × 15 drops/mL = 31.25 drops/min. So, the nurse should adjust the flow rate to deliver approximately 31 drops per minute.

A. Measure bladder before the patient voids. B. Measure bladder with head of bed raised to 90 degrees. C. Measure bladder with head of bed raised to 60 degrees. D. Measure bladder within 15 minutes after the patient voids.

Correct Answer is D

Explanation

Choice A rationale

Measuring the bladder before the patient voids would not provide an accurate measurement of postvoid residual, which is the amount of urine left in the bladder after voiding.

Choice B rationale

The position of the head of the bed does not directly impact the measurement of postvoid residual. However, the patient should be in a comfortable position during the procedure.

Choice C rationale

Similar to Choice B, the position of the head of the bed does not directly impact the measurement of postvoid residual.

Choice D rationale

Measuring the bladder within 15 minutes after the patient voids allows for an accurate measurement of postvoid residual, which can help assess bladder function.
