Nursing Elites

1. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

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

Correct answer: A

Rationale: Corrected Rationale: An electrocardiogram (ECG) should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify changes indicative of cardiac ischemia or infarction. Chest X-ray (Choice B) is not the initial diagnostic test for assessing chest pain related to myocardial infarction. Arterial blood gases (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for myocardial infarction. An echocardiogram (Choice D) may provide valuable information about cardiac structure and function, but it is not the first-line diagnostic test for acute chest pain in a client with a history of myocardial infarction.

2. A female client has been taking a high dose of prednisone, a corticosteroid, for several months. After stopping the medication abruptly, the client reports feeling 'very tired'. Which nursing intervention is most important for the nurse to implement?

• A. Measure vital signs
• B. Auscultate breath sounds
• C. Palpate the abdomen
• D. Observe the skin for bruising

Correct answer: A

Rationale: The correct answer is to measure vital signs. Abrupt withdrawal of exogenous corticosteroids can precipitate adrenal insufficiency, potentially leading to shock. Monitoring vital signs is crucial in identifying any signs of adrenal insufficiency, such as hypotension or tachycardia. Auscultating breath sounds (choice B) may be important in other situations, such as respiratory conditions, but it is not the priority in this case. Palpating the abdomen (choice C) and observing the skin for bruising (choice D) are not directly related to the potential complications of corticosteroid withdrawal and adrenal insufficiency.

3. Which nursing intervention is most important when caring for a client with myasthenia gravis?

• A. Encourage the client to rest frequently.
• B. Administer medication 30 minutes before meals.
• C. Maintain a patent airway.
• D. Monitor for signs of respiratory infection.

Correct answer: C

Rationale: Maintaining a patent airway is crucial for clients with myasthenia gravis because muscle weakness can affect the muscles responsible for breathing, potentially leading to respiratory compromise. Encouraging rest, administering medication, and monitoring for respiratory infections are important aspects of care but do not take precedence over ensuring a patent airway for adequate oxygenation.

4. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

• A. Frequency of laxative use for chronic constipation
• B. Dietary intake of magnesium-rich foods
• C. Use of magnesium-containing supplements
• D. History of alcohol use

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

5. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

• A. Anuria for the last 12 hours.
• B. Tachycardia and hypotension.
• C. Decreased urine output.
• D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.
