Nursing Elites

1. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

2. A client with newly diagnosed hypertension is prescribed enalapril (Vasotec). Which instruction should the nurse provide to the client?

• A. Increase your intake of potassium-rich foods.
• B. Report any persistent cough to your healthcare provider.
• C. Take the medication with a full meal.
• D. Avoid grapefruit juice while taking this medication.

Correct answer: B

Rationale: The correct instruction for the nurse to provide the client taking enalapril (Vasotec) is to report any persistent cough to their healthcare provider. Enalapril can cause a side effect of a persistent cough, and it is essential for the healthcare provider to be notified if this occurs to evaluate the need for a medication adjustment or change. Choices A, C, and D are incorrect. Increasing potassium-rich foods is not specifically related to enalapril use; there is no requirement to take enalapril with a full meal, and avoiding grapefruit juice is more relevant for medications metabolized by the CYP3A4 enzyme, not typically for enalapril.

3. A patient with systemic lupus erythematosus (SLE) is prescribed hydroxychloroquine. What is the most important instruction the nurse should give?

• A. Report any vision changes immediately.
• B. Take the medication with milk.
• C. Avoid high-fat foods.
• D. Increase intake of green leafy vegetables.

Correct answer: A

Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications. Choices B, C, and D are incorrect because they do not address the significant adverse effect of hydroxychloroquine on vision. Taking the medication with milk, avoiding high-fat foods, or increasing intake of green leafy vegetables are not relevant to the primary concern of monitoring for visual changes.

4. A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?

• A. Hypotension
• B. Gingival hyperplasia
• C. Bradycardia
• D. Hyperkalemia

Correct answer: B

Rationale: Gingival hyperplasia, or overgrowth of the gums, is a common side effect of phenytoin. Patients should maintain good oral hygiene to minimize this effect.

5. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?

• A. Diverticular bleed
• B. Duodenal ulcer
• C. Inflammatory bowel disease
• D. Vascular ectasia (watermelon stomach)

Correct answer: B

Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.
