Nursing Elites

1. 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.

2. A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: When a patient is prescribed lisinopril, an ACE inhibitor, the nurse should monitor for hyperkalemia. Lisinopril can cause hyperkalemia by decreasing aldosterone secretion, which leads to potassium retention in the body. Hyperkalemia is a potential side effect of ACE inhibitors and should be closely monitored, as it can have serious consequences such as affecting cardiac function.

3. The client has acute pancreatitis. Which nursing intervention is the highest priority?

• A. Administer pain medication as prescribed.
• B. Monitor the client's serum amylase and lipase levels.
• C. Encourage oral intake of clear liquids.
• D. Assess the client's bowel sounds every 4 hours.

Correct answer: A

Rationale: Administering pain medication as prescribed is the highest priority when caring for a client with acute pancreatitis. Acute pancreatitis is often associated with severe abdominal pain, and alleviating this pain is crucial for the client's comfort and well-being. Pain management can also help reduce stress on the pancreas and promote recovery. Monitoring serum amylase and lipase levels, encouraging oral intake of clear liquids, and assessing bowel sounds are important interventions but addressing the client's pain takes precedence to provide immediate relief and improve outcomes.

4. A 56-year-old woman with rheumatoid arthritis has severe joint pain and swelling in her hands. She has a history of peptic ulcer disease five years ago but presently has no GI symptoms. You elect to start her on an NSAID. Which of the following is correct?

• A. Proton-pump inhibitors and H2-blockers are equally effective in prophylaxis against NSAID-related GI toxicity.
• B. Misoprostol is superior to an H2-blocker in prophylaxis against NSAID-related GI toxicity.
• C. Sucralfate is not the drug of choice for prophylaxis in this patient.
• D. H. pylori infection can alter the risk for an NSAID-induced ulcer.

Correct answer: B

Rationale: In this scenario, the patient's history of peptic ulcer disease puts her at risk for NSAID-related GI toxicity. Misoprostol and proton-pump inhibitors have shown superiority over H2-blockers in preventing NSAID-related GI toxicity. H. pylori infection can indeed increase the risk of an NSAID-induced ulcer in infected patients who are starting NSAID therapy. Sucralfate has not been proven to be effective in prophylaxis against NSAID-related GI toxicity. Therefore, the correct choice is B, as misoprostol is the preferred option over an H2-blocker in this context.

5. A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?

• A. Stimulate white blood cell production
• B. Increase platelet count
• C. Promote red blood cell production
• D. Enhance clotting factor production

Correct answer: C

Rationale: Erythropoietin is a hormone that primarily stimulates the bone marrow to produce more red blood cells. By increasing red blood cell production, erythropoietin helps to improve oxygen delivery to tissues, which is essential in managing anemia. Choices A, B, and D are incorrect because erythropoietin specifically targets red blood cell production and does not have a direct effect on white blood cells, platelets, or clotting factors.
