A client who weighs 176 pounds is admitted to the intensive care unit with a serum glucose level of 600 mg/dL (33.3 mmol/L). Regular insulin at a rate of 0.1 unit/kg/hour is prescribed. The pharmacy provides a solution of regular insulin 100 units/100 mL of normal saline.

The nurse should set the infusion pump to deliver how many mL/hours?

(Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["8"]

Step 1: Convert the client's weight from pounds to kilograms. 176 pounds ÷ 2.2 = 80 kg

Step 2: Determine the total units of insulin needed per hour. 80 kg × 0.1 unit/kg/hour = 8 units/hour

Step 3: Determine the volume of insulin solution needed per hour. (8 units) ÷ (100 units/100 mL) = (8 units) ÷ (1 unit/mL) = 8 mL/hour

So, the nurse should set the infusion pump to deliver 8 mL/hour.

Correct Answer is D

Explanation

Choice A reason: Applying drying agents on draining lesions every day is not recommended for clients with SLE. This approach can lead to excessive dryness and irritation of the skin, which can worsen the condition and cause additional discomfort. Moisturizing and protecting the skin are more appropriate measures.

Choice B reason: While avoiding contact with others can help prevent the spread of infections, it is not the most important aspect of skin care for SLE. SLE is an autoimmune condition, and managing skin care focuses more on protecting the skin from external triggers and minimizing inflammation.

Choice C reason: Tanning booths are not safe for clients with SLE. Exposure to UV light, whether from the sun or artificial sources, can exacerbate SLE symptoms and trigger flares. Therefore, it is important to avoid both direct sunlight and tanning booths.

Choice D reason: Using a very strong sunblock when out in the sun is crucial for clients with SLE. Sun exposure can worsen skin lesions and trigger flares, so it is essential to protect the skin with a high SPF sunblock, wear protective clothing, and seek shade whenever possible.

A. "Failure to keep your lungs working may result in pneumonia after surgery which could, in turn, result in death." B. "Incentive spirometry is conducted routinely after surgery and will be demonstrated when you return from surgery." C. "You will use the incentive spirometer for the first postoperative day until deep breathing and coughing can be done comfortably." D. "Deep breathing exercises are encouraged to maintain lung capacity and to strengthen respiratory muscles, which will help prevent complications."

Correct Answer is D

Explanation

Choice A reason: While it is important to communicate the risks of not using the incentive spirometer, this statement is overly alarming and may cause unnecessary anxiety for the client. It is better to focus on positive outcomes and preventive measures.

Choice B reason: This statement informs the client that incentive spirometry is routine and will be demonstrated postoperatively, but it does not provide specific details about its benefits or importance.

Choice C reason: This statement explains the use of the incentive spirometer on the first postoperative day, but it does not address the overall goal of preventing complications through lung exercises.

Choice D reason: This statement effectively explains the purpose and benefits of deep breathing exercises, including using the incentive spirometer. It emphasizes the importance of maintaining lung capacity and strengthening respiratory muscles to prevent complications, providing a clear rationale for the intervention.
