Nursing Elites

1. The licensed practical nurse is observing a graduate nurse as she assesses the central venous pressure. Which observation would indicate that the graduate needs further teaching?

• A. The graduate places the client in a supine position to read the manometer.
• B. The graduate turns the stop-cock to the off position from the IV fluid to the client.
• C. The graduate instructs the client to perform the Valsalva maneuver during the CVP reading.
• D. The graduate notes the level at the top of the meniscus.

Correct answer: C

Rationale: The correct answer is C because the client should breathe normally during a central venous pressure monitor reading. Placing the client in a supine position (Choice A) is correct if the client can tolerate it. Turning the stop-cock off (Choice B) and noting the level at the top of the meniscus (Choice D) are also correct actions during CVP monitoring. Instructing the client to perform the Valsalva maneuver is incorrect as it can artificially alter the CVP reading, indicating a need for further teaching.

2. The physician has prescribed tranylcypromine sulfate (Parnate) 10mg bid. The nurse should teach the client to refrain from eating foods containing tyramine because it may cause:

• A. Hypertension
• B. Hyperthermia
• C. Melanoma
• D. Urinary retention

Correct answer: A

Rationale: If the client eats foods high in tyramine, he might experience malignant hypertension. Tyramine is found in cheese, sour cream, Chianti wine, sherry, beer, pickled herring, liver, canned figs, raisins, bananas, avocados, chocolate, soy sauce, fava beans, and yeast. These episodes are treated with Regitine, an alpha-adrenergic blocking agent. Choices B, C, and D are unrelated to the question: Hyperthermia is excessive body temperature, melanoma is a type of skin cancer, and urinary retention is the inability to empty the bladder.

3. How should Lasix be administered to prevent hypotension?

• A. By administering it over 1-2 minutes
• B. By hanging it IV piggyback
• C. With normal saline only
• D. By administering it through a venous access device

Correct answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

4. 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 scheduled for surgical repair of a sacular abdominal aortic aneurysm is the identification of peripheral pulses. This is essential because during surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Monitoring peripheral pulses helps assess circulation to the lower extremities, ensuring adequate perfusion. While assessing the client's anxiety level (choice A) is important, it is not as critical as monitoring peripheral pulses in this case. Evaluating exercise tolerance (choice B) is not typically recommended preoperatively for this specific condition. Assessing bowel sounds and activity (choice D) is also relevant but takes a lower priority compared to identifying peripheral pulses in this scenario.

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.
