Nursing Elites

1. While the client is receiving quinidine, the nurse should monitor the ECG for:

• A. Peaked P wave
• B. Elevated ST segment
• C. Inverted T wave
• D. Prolonged QT interval

Correct answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.

2. Following the change of shift report, when can or should the nurse alter or modify the plan?

• A. halfway through the shift
• B. at the end of the shift before handing over
• C. when needs change
• D. after the top-priority tasks have been completed

Correct answer: C

Rationale: The correct answer is 'when needs change.' The nurse should be flexible and adjust the plan as necessary when the needs of the patients change. This ensures that care is provided effectively and efficiently. Choices A, B, and D are incorrect because altering the plan based on time intervals, solely at the end of the shift, or after completing top-priority tasks may not align with the current needs of the patients.

3. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

4. The physician has ordered sodium warfarin (Coumadin) for the client with thrombophlebitis. The order should be entered to administer the medication at:

• A. 900
• B. 1200
• C. 1700
• D. 2100

Correct answer: C

Rationale: Sodium warfarin is typically administered in the late afternoon, around 1700 hours. This timing allows for accurate bleeding times to be drawn in the morning. Administering it at 0900 (choice A) would not align with this schedule and may affect the monitoring of bleeding times. Choice B (1200) is midday, which is not the recommended time for sodium warfarin administration. Choice D (2100) is in the evening, which is also not ideal. Therefore, the correct time for administering sodium warfarin is 1700 (choice C).

5. The nurse is caring for a client scheduled for a surgical repair of a sacular abdominal aortic aneurysm. Which assessment is most crucial during the preoperative period?

• A. Assessment of the client's level of anxiety
• B. Evaluation of the client's exercise tolerance
• C. Identification of peripheral pulses
• D. Assessment of bowel sounds and activity

Correct answer: C

Rationale: The most crucial assessment during the preoperative period for a client with a sacular abdominal aortic aneurysm scheduled for surgical repair is the identification of peripheral pulses. During surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Therefore, it is essential for the nurse to assess peripheral pulses and monitor the return of circulation to the lower extremities postoperatively. Assessing the client's level of anxiety (Choice A) is important but not as crucial as ensuring adequate circulation. Evaluating exercise tolerance (Choice B) is not recommended preoperatively for this situation. Assessing bowel sounds and activity (Choice D) is of lesser concern compared to the critical need to monitor peripheral circulation.
