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. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. What respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.

3. A client is receiving intravenous (IV) fluids postoperatively. Which assessment finding should prompt the nurse to stop the infusion and notify the healthcare provider?

• A. The client reports pain at the IV site
• B. The client’s blood pressure is elevated
• C. The client has swelling at the IV site
• D. The client’s heart rate is irregular

Correct answer: C

Rationale: Swelling at the IV site may indicate infiltration or phlebitis, which requires stopping the IV infusion and notifying the healthcare provider. Infiltration occurs when the IV fluid leaks into the surrounding tissue, causing swelling and potential damage. It is crucial to act promptly to prevent further complications and ensure the client's safety.

4. The healthcare provider is caring for a client diagnosed with type 2 diabetes mellitus. Which intervention should the healthcare provider implement to assess the client’s glycemic control?

• A. Monitor fasting blood glucose levels
• B. Check urine for ketones
• C. Evaluate hemoglobin A1c levels
• D. Assess the client’s dietary intake

Correct answer: C

Rationale: Evaluating hemoglobin A1c levels is the most appropriate intervention to assess glycemic control in a client with type 2 diabetes mellitus. Hemoglobin A1c levels reflect the average blood glucose control over the past 2-3 months, providing valuable information for monitoring and managing diabetes. Monitoring fasting blood glucose levels (Choice A) is important for daily management but does not provide a long-term view like hemoglobin A1c. Checking urine for ketones (Choice B) is more relevant for assessing diabetic ketoacidosis. Assessing dietary intake (Choice D) is crucial for overall diabetes management but does not directly assess glycemic control.

5. When assessing a male client, the nurse finds that he is fatigued and experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client’s laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client’s laboratory values for potassium levels will help confirm the presence of hypokalemia.
