Nursing Elites

1. A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?

• A. Decreased peripheral edema.
• B. Elevated blood pressure.
• C. Increased heart rate.
• D. Decreased urine output.

Correct answer: A

Rationale: The correct answer is A: 'Decreased peripheral edema.' In a client with heart failure receiving furosemide, decreased peripheral edema indicates that the medication is effectively reducing fluid overload. Furosemide is a diuretic that helps the body eliminate excess fluid and salt through increased urine output, leading to a reduction in peripheral edema, which is a common symptom of heart failure. Monitoring and recognizing this improvement in edema are crucial in managing heart failure effectively.

2. A client with heart failure is prescribed digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse teach the client to report?

• A. Increased appetite.
• B. Yellow or blurred vision.
• C. Weight gain.
• D. Nasal congestion.

Correct answer: B

Rationale: Yellow or blurred vision is a hallmark sign of digoxin toxicity. Digoxin toxicity can affect various body systems, but visual disturbances, such as yellow or blurred vision, are important signs that the client should report immediately. Other signs like increased appetite, weight gain, or nasal congestion are not typically associated with digoxin toxicity. Prompt reporting of visual disturbances can help prevent further complications associated with digoxin toxicity.

3. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

4. 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.

5. A client with chronic renal failure is scheduled to receive epoetin alfa (Epogen). Which laboratory result should the nurse review before administering the medication?

• A. Blood urea nitrogen (BUN)
• B. Creatinine clearance
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is to review the hemoglobin level before administering epoetin alfa (Epogen) to assess its effectiveness in stimulating red blood cell production. Hemoglobin level is a crucial indicator to monitor in clients with chronic renal failure receiving this medication. Choice A (Blood urea nitrogen) and Choice B (Creatinine clearance) are commonly monitored in renal failure but are not specifically relevant to assessing the effectiveness of epoetin alfa. Choice D (Serum potassium) is important to monitor due to potential imbalances in renal failure, but it is not directly related to evaluating the effectiveness of epoetin alfa.
