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. A family member of a client with a diagnosis of Schizophrenia asks about the prognosis. The nurse's response is based on the knowledge that schizophrenia:

• A. affects both genders equally.
• B. is a chronic, deteriorating disease with periods of remission.
• C. is usually diagnosed in early adulthood.
• D. does not have a clear protective hormone effect delaying diagnosis.

Correct answer: B

Rationale: The correct answer is B: 'is a chronic, deteriorating disease with periods of remission.' While choices A, C, and D contain some truths about schizophrenia, they do not directly address the prognosis aspect of the question. Schizophrenia can affect both men and women equally, is typically diagnosed in early adulthood, and does not have a known protective hormone effect that delays diagnosis. Choice B accurately reflects the chronic and fluctuating nature of the disease, which is essential for understanding its long-term course.

3. Activities of effective supervisors can be task-related or people-related activities. An example of a task-related supervisory activity is:

• A. coaching.
• B. evaluating.
• C. delegating.
• D. facilitating.

Correct answer: C

Rationale: Delegating is the act of assigning work to those capable and competent to do the work, making it a task-related supervisory activity. Coaching, evaluating, and facilitating are people-related supervisory activities. Coaching involves guiding and developing individuals, evaluating entails assessing performance, and facilitating focuses on enabling tasks and processes. These activities are more centered on interacting with and supporting people rather than directly assigning tasks. Therefore, in the context of task-related activities, delegating stands out as the correct choice.

4. The nurse is preparing a client for mammography. To prepare the client for a mammogram, the nurse should tell the client:

• A. To omit creams, powders, or deodorants before the exam
• B. To restrict fat intake for 1 week before the test
• C. That mammography replaces the need for self-breast exams
• D. That mammography requires a higher dose of radiation than an x-ray

Correct answer: A

Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.

5. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.
