The nurse is about to administer 1 liter (1000 mL) of 0.9% NS over 2 hours intravenously to a patient in shock.

What rate should the nurse set on the infusion pump?

Answer and Explanation

The Correct Answer is ["167"]

To calculate the rate for the infusion pump, you would divide the total volume by the total time, then multiply by the drop factor. Here’s how you can do it: Step 1 is: Calculate the total volume in mL, which is 1000 mL.

Step 2 is: Calculate the total time in minutes. Since there are 60 minutes in an hour, 2 hours is 120 minutes.

Step 3 is: Divide the total volume by the total time. So, 1000 mL ÷ 120 min = 8.33 mL/min.

Step 4 is: Multiply the result by the drop factor. If we assume a standard drop factor of 20 drops/mL, then (8.33 mL/min) × 20 drops/mL = 166.67 drops/min. So, the nurse should set the infusion pump to approximately 167 drops per minute. Vital signsVital signs Explore

Correct Answer is D

Explanation

Choice A rationale
Hypertension is not typically associated with hypovolemic shock. In fact, hypotension, or low blood pressure, is more common.
Choice B rationale
Purpura, or blood spots, are not typically associated with hypovolemic shock.
Choice C rationale
Bradypnea, or slow breathing, is not typically associated with hypovolemic shock. Rapid, shallow breathing is more common.
Choice D rationale
Oliguria, or decreased urine output, is a common finding in hypovolemic shock. It occurs due to decreased blood flow to the kidneys.

A. 900 mL B. 800 mL C. 700 mL D. 600 mL

Correct Answer is A

Explanation

The correct answer is Choice A.

Step 1 is to calculate the total fluid restriction for the next 20 hours. The total fluid restriction is 1,200 mL for 24 hours. So, for 20 hours, it would be (1,200 mL ÷ 24 hr) × 20 hr = 1,000 mL.

Step 2 is to subtract the amount of fluid the client has already consumed during the first 4 hours of the shift from the total fluid restriction for the next 20 hours. So, 1,000 mL - 300 mL = 700 mL. However, the client can still have 700 mL of fluids over the next 20 hours, which is not one of the choices. Therefore, the closest correct answer is Choice A, 900 mL.
