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

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.

2. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

3. 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?

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.

4. A client with schizophrenia says, 'I'm away for the day ... but don't think we should play "? or do we have feet of clay?' Which alteration in the client's speech does the nurse document?

Correct answer: D

Rationale: The correct answer is 'Associative looseness.' In the provided speech, the client shows associative looseness by making loose connections between phrases without a clear logical link. Clang association involves rhyming words without regard for their meaning. Neologism refers to made-up words with specific meaning to the client, and word salad is a jumble of words that lack coherence either to the listener or the client. Understanding these speech patterns associated with schizophrenia is crucial in identifying the specific alteration in speech displayed by the client in this scenario.

5. When teaching clients with a diagnosis of Schizophrenia nearing discharge from a residential care facility, what is an essential topic to include?

Correct answer: B

Rationale: When educating clients with Schizophrenia nearing discharge, it is crucial to focus on teaching them how to recognize and manage symptoms of relapse. Clients are usually aware of these symptoms, such as feeling anxious and overwhelmed, before the onset of psychosis. This early stage is vital for intervention, which involves finding a safe environment, seeking help, avoiding stressors, and reducing stimuli. Understanding and managing relapse symptoms empower clients to take proactive steps in their care. Choices A and C are not as immediate and practical as recognizing symptoms of relapse for client safety and well-being. While contact with follow-up care is important, it is not as urgent and specific as knowing how to manage relapse symptoms for immediate intervention.
