Nursing Elites

1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Serum magnesium level

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.

2. A client with a history of congestive heart failure is admitted with shortness of breath. Which nursing intervention should the nurse implement first?

• A. Elevate the head of the bed.
• B. Administer prescribed diuretic therapy.
• C. Monitor the client's oxygen saturation.
• D. Assess the client's level of consciousness.

Correct answer: A

Rationale: The correct answer is to elevate the head of the bed. Elevating the head of the bed is crucial in improving oxygenation in clients with congestive heart failure and shortness of breath by reducing venous return to the heart and decreasing fluid overload in the lungs. This intervention helps to alleviate the client's breathing difficulty. Administering diuretic therapy (Choice B) may be necessary but is not the initial priority. Monitoring oxygen saturation (Choice C) is important but should come after ensuring proper positioning. Assessing the client's level of consciousness (Choice D) is essential but is not the first intervention needed for a client experiencing respiratory distress.

3. 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.

4. The nurse is assessing a female client's blood pressure because she reported feeling dizzy. The blood pressure cuff is inflated to 140 mm Hg and as soon as the cuff is deflated a Korotkoff sound is heard. Which intervention should the nurse implement next?

• A. Wait 1 minute and palpate the systolic pressure before auscultating again.
• B. Increase the inflation pressure by 20 mm Hg and measure again.
• C. Switch to a larger cuff and repeat the measurement.
• D. Document the finding as normal.

Correct answer: A

Rationale: If a Korotkoff sound is heard immediately upon deflation, it may indicate an inaccurate reading. Waiting and palpating the systolic pressure can help confirm the accuracy of the measurement. Choice A is the correct intervention because it allows the nurse to ensure the accuracy of the blood pressure reading. Choice B is incorrect as increasing the inflation pressure is not necessary in this situation. Choice C is also incorrect as switching to a larger cuff is not warranted based on the information provided. Choice D is incorrect because documenting the finding as normal without further verification could lead to inaccurate information.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Elevate the head of the bed.
• C. Assess the client's level of consciousness.
• D. Obtain a sputum culture.

Correct answer: A

Rationale: Administering oxygen therapy as prescribed is the initial priority when managing an exacerbation of COPD. In COPD exacerbations, the primary concern is hypoxemia due to impaired gas exchange. Administering oxygen helps to improve oxygenation and prevent further complications. Elevating the head of the bed can aid in breathing comfort but is not the priority over ensuring adequate oxygen supply. Assessing the client's level of consciousness is important but comes after ensuring oxygenation. Obtaining a sputum culture is relevant for identifying pathogens but is not the immediate priority in addressing hypoxemia.
