Nursing Elites

1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. Which assessment finding indicates to the nurse a client's readiness for pulmonary function tests?

• A. Expresses an understanding of the procedure.
• B. NPO for 6 hrs.
• C. No known drug allergies.
• D. Intravenous access intact.

Correct answer: A

Rationale: The correct answer is A: 'Expresses an understanding of the procedure.' This choice indicates that the client is mentally prepared for the pulmonary function tests, as understanding the procedure shows readiness and cooperation. Choices B, C, and D are incorrect. Choice B, 'NPO for 6 hrs,' pertains to fasting status and is not directly related to readiness for the test. Choice C, 'No known drug allergies,' is important information but does not specifically indicate readiness for pulmonary function tests. Choice D, 'Intravenous access intact,' is related to vascular access and not a direct indicator of readiness for the pulmonary function tests.

3. The nurse is assessing a client with right-sided heart failure. Which finding requires immediate intervention?

• A. Jugular venous distention
• B. Peripheral edema
• C. Crackles in the lungs
• D. Elevated liver enzymes

Correct answer: C

Rationale: In a client with right-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potential respiratory distress. Jugular venous distention (Choice A) and peripheral edema (Choice B) are common findings in right-sided heart failure but do not indicate acute deterioration requiring immediate intervention. Elevated liver enzymes (Choice D) may be seen in chronic heart failure but do not warrant immediate action compared to the urgent need to address pulmonary congestion indicated by crackles in the lungs.

4. A client with hyperthyroidism who has not been responsive to medications is admitted for evaluation. What action should the nurse implement?

• A. Notify the healthcare provider.
• B. Review the client's medication history.
• C. Prepare the client for thyroid function tests.
• D. Initiate seizure precautions.

Correct answer: A

Rationale: In a scenario where a client with hyperthyroidism is not responding to medications, the nurse's priority action should be to notify the healthcare provider. This is important because the client may require immediate intervention, such as adjusting the treatment plan or exploring alternative therapies. Reviewing the client's medication history (choice B) may be relevant but not as urgent as involving the healthcare provider. While preparing the client for thyroid function tests (choice C) may be necessary as part of the evaluation process, it is not the most immediate action to take. Initiating seizure precautions (choice D) is not directly related to the non-responsiveness of medications in hyperthyroidism and is not a priority in this situation.

5. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Chest X-ray
• B. Arterial blood gases (ABGs)
• C. Echocardiogram
• D. Electrocardiogram (ECG)

Correct answer: C

Rationale: The correct answer is C: Echocardiogram. An echocardiogram should be performed first to assess ventricular function and evaluate the cause of shortness of breath and crackles in a client with heart failure. An echocardiogram provides valuable information about the heart's structure and function, helping to identify potential issues related to heart failure. Chest X-ray (Choice A) may be done to assess for changes in heart size or fluid in the lungs but does not directly assess heart function. Arterial blood gases (Choice B) may provide information about oxygenation but do not directly evaluate heart function. An electrocardiogram (Choice D) assesses the heart's electrical activity but does not provide detailed information about ventricular function, which is crucial in heart failure management.
