A client is currently receiving an infusion labeled Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 mL at 14 ml/hour. A prescription is received to change the rate of the Infusion to 900 units of heparin per hour. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["18"]

First, we need to find the concentration of Heparin per milliliter in the current infusion. We can do this by dividing the total number of Heparin units by the total volume of the infusion:

Heparin concentration (units/mL) = Total Heparin units / Total volume (mL) Heparin concentration = 25,000 units / 500 mL

Heparin concentration = 50 units/mL

Now, we know the desired rate of Heparin delivery (900 units/hour) and the concentration of Heparin per milliliter (50 units/mL). We can use this information to calculate the required flow rate in milliliters per hour:

Flow rate (mL/hour) = Desired Heparin rate (units/hour) / Heparin concentration (units/mL)

Flow rate = 900 units/hour / 50 units/mL Flow rate = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver 18 mL/hour.

Correct Answer is B

Explanation

A. Collaborating with a science teacher to prepare a health lesson may be beneficial for health education but does not directly address secondary prevention. Secondary prevention involves early detection and intervention to prevent the progression of disease or injury.

B. Initiating a hearing and vision screening program for first graders is an example of secondary prevention. This action aims to detect any hearing or vision problems early, allowing for timely intervention and management to prevent further complications or difficulties in learning and
development.

C. Preparing a presentation on how to prevent the spread of lice may be important for promoting hygiene and preventing infestations, but it falls more under the category of health education and primary prevention rather than secondary prevention.

D. Observing a person with type 1 diabetes mellitus self-administer a dose of insulin may be related to health education or management of a chronic condition, but it does not directly address secondary prevention for school-aged children.

A. Plan to observe the secured IV site after the insertion procedure. B. Remind the nurse to tape the gauze dressing securely in place. C. Confirm that the nurse has gathered the necessary supplies. D. Instruct the nurse to use a transparent dressing over the site.

Correct Answer is D

Explanation

A. Plan to observe the secured IV site after the insertion procedure.
This is a proactive step, but it does not address the immediate need to correct the new nurse’s choice of dressing.

B. Remind the nurse to tape the gauze dressing securely in place.
While securing the dressing is important, it is not the best practice to use a gauze dressing for IV sites as it obscures the view of the insertion site.

C. Confirm that the nurse has gathered the necessary supplies.
Confirming supplies is important, but this does not address the incorrect dressing choice.

D. Instruct the nurse to use a transparent dressing over the site.
This is the correct answer because a transparent dressing allows for continuous visual inspection of the IV site for signs of infection or infiltration, which is crucial for patient safety.
