Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?

• A. 13 ml/hour.
• B. 63 ml/hour.
• C. 80 ml/hour.
• D. 125 ml/hour.

Correct answer: B

Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.

3. The client, who is newly diagnosed with arteriosclerosis and is obese, is being educated by the nurse on reducing the risk of a heart attack or stroke. Which health promotion brochure should the nurse provide to this client?

• A. Monitoring Your Blood Pressure at Home
• B. Smoking Cessation as a Lifelong Commitment
• C. Decreasing Cholesterol Levels Through Diet
• D. Stress Management for a Healthier You

Correct answer: C

Rationale: The most significant risk factor contributing to arteriosclerosis is excess dietary fat, particularly saturated fat and cholesterol. Therefore, the most crucial brochure for the nurse to provide to the client focuses on decreasing cholesterol levels through diet to help reduce the risk of heart attack or stroke.

4. An unlicensed assistive personnel (UAP) places a client in a left lateral position prior to administering a soap suds enema. Which instruction should the nurse provide the UAP?

• A. Position the client on the right side of the bed in reverse Trendelenburg.
• B. Fill the enema container with 1000 ml of warm water and 5 ml of castile soap.
• C. Reposition the client in the Sims' position.
• D. Raise the side rails on both sides of the bed and elevate the bed to waist level.

Correct answer: C

Rationale: The correct position for administering a soap suds enema is the Sims' position, not the left lateral position. The Sims' position allows the enema solution to follow the anatomical course of the intestines and provides the best overall results. By repositioning the client in the Sims' position, the weight is distributed to the anterior ilium, facilitating the enema administration process.

5. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?

• A. Superficial veins are more easily found in the feet and ankles.
• B. A decreased flow rate could lead to thrombosis formation.
• C. It is more challenging to move a cannulated extremity when using the leg or foot.
• D. Veins in the feet and ankles are located deep, making the procedure more painful.

Correct answer: B

Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
