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. 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.

3. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

4. The nurse observes an unlicensed assistive personnel (UAP) taking a client's blood pressure with a cuff that is too small, but the blood pressure reading obtained is within the client's usual range. What action is most important for the nurse to implement?

• A. Tell the UAP to use a larger cuff at the next scheduled assessment.
• B. Reassess the client's blood pressure using a larger cuff.
• C. Have the unit educator review this procedure with the UAPs.
• D. Teach the UAP the correct technique for assessing blood pressure.

Correct answer: B

Rationale: The most important action is to ensure that an accurate BP reading is obtained. The nurse should reassess the blood pressure with the correct size cuff (B) to obtain an accurate reading. Postponing reassessment (A) could lead to inaccurate results. While (C and D) are important actions for education and quality improvement, they are not as critical as obtaining an accurate blood pressure reading in this situation.

5. A client is admitted to the hospital with a diagnosis of pneumonia. Which laboratory test result should the nurse monitor to evaluate the client’s respiratory function?

• A. Arterial blood gases (ABGs)
• B. Complete blood count (CBC)
• C. Blood glucose levels
• D. Serum electrolyte levels

Correct answer: A

Rationale: Arterial blood gases (ABGs) are the most appropriate laboratory test to monitor respiratory function in a client with pneumonia. ABGs provide valuable information on oxygenation status, acid-base balance, and how well the lungs are exchanging gases. This information helps in assessing the effectiveness of ventilation and oxygenation, guiding treatment decisions, and evaluating the overall respiratory status of the client.
