Nursing Elites

1. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

2. A client with portal hypertension who has developed ascites is scheduled for a paracentesis. What pre-procedure nursing intervention is essential?

• A. Encourage the client to empty the bladder
• B. Administer a laxative to clear the bowels
• C. Restrict the client's fluid intake
• D. Place the client in a supine position

Correct answer: A

Rationale: Emptying the bladder before a paracentesis is essential to prevent bladder injury during the procedure. A full bladder may be in the path of the needle insertion, increasing the risk of bladder puncture. Encouraging the client to empty the bladder ensures their safety and reduces the likelihood of complications.

3. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.

4. A client with cirrhosis of the liver is experiencing pruritus. Which intervention should the nurse implement to help relieve the client's symptoms?

• A. Administer acetaminophen (Tylenol).
• B. Apply lotion to the skin.
• C. Encourage a high-protein diet.
• D. Provide a warm bath.

Correct answer: B

Rationale: Pruritus is a common symptom in clients with cirrhosis due to bile salts accumulating in the skin. Applying lotion to the skin helps soothe the itching and can prevent skin breakdown. Acetaminophen can worsen liver damage in clients with cirrhosis as it is metabolized in the liver. Encouraging a high-protein diet is not directly related to relieving pruritus. Providing a warm bath may further dry the skin, exacerbating the itching. Therefore, the most appropriate intervention to help relieve pruritus in a client with cirrhosis is to apply lotion to the skin.

5. A 56-year-old white male complains of intermittent dysphagia for the past three months, particularly with the ingestion of meat. He has no difficulties swallowing liquids. He has no history of smoking, uses no medications, and has had no weight loss. What test would be best to evaluate him?

• A. Upper endoscopy
• B. Chest/abdominal CT scan
• C. Barium swallow
• D. Esophageal manometry

Correct answer: C

Rationale: For a patient presenting with intermittent dysphagia, especially with solids like meat, a barium swallow is the most appropriate initial test. In this case, the classic presentation suggests a Schatzki’s ring, which is best visualized through a barium study. Upper endoscopy may not always visualize Schatzki’s rings effectively. Chest/abdominal CT scan and esophageal manometry are not the preferred tests for diagnosing Schatzki’s rings. Treatment for Schatzki’s rings often involves bougie dilatation, and no further therapy may be necessary.
