The healthcare provider prescribes regular insulin 10 units/hr IV. The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline. How many mL/hr should the nurse program the infusion pump? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["10"]

To determine the mL/hr rate for the regular insulin infusion, we can set up a proportion: 10 units/hr (prescribed rate) = x mL/hr (unknown rate)

Since the IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline, we know that each mL of the solution contains 1 unit of regular insulin.

So, if 1 mL contains 1 unit, then x mL contains 10 units. x = 10 mL/hr

Correct Answer is A

Explanation

A. A high-pitched sound heard upon inspiration, known as a "stridor," can indicate airway obstruction or respiratory distress. In the postoperative period following an appendectomy, airway patency and adequate ventilation are essential for the client's oxygenation and recovery.
B. While a slightly elevated heart rate may be expected in the immediate postoperative period due to stress or pain, it does not typically require immediate action unless accompanied by other concerning symptoms.
C. Redness and edema at the incision site can be normal inflammatory responses following surgery.
D. Pain is common after surgery, and a pain rating of 8 on a scale of 0 to 10 indicates moderate to severe pain.

A. Auscultate lungs for unequal breath sounds. B. Continue to monitor the drainage system. C. Lift and clear drainage from the chest tube. D. Inspect the tube insertion site for leaking.

Correct Answer is B

Explanation

B. Tidaling is an expected finding in a functioning chest drainage system and indicates proper drainage of air or fluid from the pleural space. Continuously monitoring the drainage system allows the nurse to assess the volume, color, and consistency of drainage.
A. Rising water levels during inspiration and falling during expiration are indicative of proper chest tube function, therefore, auscultation for breath sounds may not provide additional relevant information related to the functioning of the chest tube.
C. Performing this action unnecessarily may disrupt the functioning of the drainage system and should only be done if specifically instructed by the healthcare provider.
D. While it is important to monitor for leaks, the observation of tidaling in the water-seal chamber does not necessarily indicate a leak at the insertion site.
