The nurse is preparing to test a patient for postvoid residual with a bladder scan. Which action will the nurse take?

Measure bladder before the patient voids.

Measure bladder with head of bed raised to 90 degrees.

Measure bladder with head of bed raised to 60 degrees.

Measure bladder within 15 minutes after the patient voids.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is A

Explanation

Choice A rationale

A black pressure ulcer indicates necrotic tissue, which often requires surgical debridement.

Choice B rationale

Increased drainage from the wound is not typically associated with a black pressure ulcer.

Choice C rationale

While documenting the wound status daily is part of wound care, it is not a specific event anticipated when planning care for a patient with a black pressure ulcer.

Choice D rationale

Increased monitoring of the wound condition is part of wound care, but it is not a specific event anticipated when planning care for a patient with a black pressure ulcer.

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.
