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 client from a nursing home is admitted with urinary sepsis and has a single-lumen, peripherally-inserted central catheter (PICC). Four medications are prescribed for 9:00 a.m. and the nurse is running behind schedule. Which medication should the nurse administer first?

• A. Piperacillin/tazobactam (Zosyn) in 100 ml D5W, IV over 30 minutes q8 hours.
• B. Vancomycin (Vancocin) 1 gm in 250 ml D5W, IV over 90 minutes q12 hours.
• C. Pantoprazole (Protonix) 40 mg PO daily.
• D. Enoxaparin (Lovenox) 40 mg subq q24 hours.

Correct answer: A

Rationale: In a patient with urinary sepsis, administering Piperacillin/tazobactam first is crucial as it is an antibiotic that directly targets the infection. Addressing the infection promptly is essential to prevent its progression and complications. Vancomycin, Pantoprazole, and Enoxaparin are important medications for the patient's overall treatment plan, but in this scenario, the antibiotic should take precedence due to the urgency of managing the sepsis.

3. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

4. A client is admitted with suspected meningitis. Which assessment finding requires immediate intervention?

• A. Headache.
• B. Fever.
• C. Nuchal rigidity.
• D. Seizures.

Correct answer: D

Rationale: Seizures in a client with suspected meningitis indicate increased intracranial pressure or other complications requiring immediate intervention. Seizures can lead to further neurological damage and need prompt management to prevent adverse outcomes. Therefore, addressing seizures promptly is crucial in the care of a client with suspected meningitis.

5. A client with acute pancreatitis is admitted to the hospital. What is the priority nursing intervention for this client?

• A. Administering oral pancreatic enzymes
• B. Encouraging a high-protein diet
• C. Maintaining NPO status and administering IV fluids
• D. Providing a low-fat diet

Correct answer: C

Rationale: The priority nursing intervention for a client with acute pancreatitis is to maintain NPO (nothing by mouth) status and administer IV fluids. This approach helps rest the pancreas, decrease pancreatic stimulation, and prevent further exacerbation of the condition. By withholding oral intake and providing IV fluids, the pancreas is given the opportunity to recover and inflammation can be reduced. This intervention is crucial in the acute phase of pancreatitis to support the healing process and prevent complications.
