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 healthcare professional is interested in studying the incidence of infant death in a particular city and wants to compare that city's rate to the state's rate. What state resource is most likely to provide this information?

• A. Disease registry.
• B. Department of Health.
• C. Bureau of Vital Statistics.
• D. Census data.

Correct answer: C

Rationale: The Bureau of Vital Statistics collects data on births and deaths, including infant mortality rates. This data is crucial for healthcare professionals to analyze and compare rates between different regions.

3. A patient with type 2 diabetes is prescribed metformin. What instruction should the nurse provide regarding this medication?

• A. Take the medication on an empty stomach.
• B. Monitor for signs of hypoglycemia.
• C. Take the medication with meals.
• D. Increase intake of simple carbohydrates.

Correct answer: C

Rationale: The correct instruction for a patient prescribed metformin is to take the medication with meals. This helps reduce gastrointestinal side effects commonly associated with metformin. Patients should also be educated about the signs of lactic acidosis, a rare but serious side effect associated with metformin use.

4. A 40-year-old woman presents with a history of chronic constipation, bloating, and abdominal pain. She notes that the pain is relieved with defecation. She denies any weight loss, blood in her stools, or nocturnal symptoms. Physical examination and routine blood tests are normal. What is the most likely diagnosis?

• A. Inflammatory bowel disease
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Lactose intolerance

Correct answer: B

Rationale: The patient's symptoms of chronic constipation, bloating, abdominal pain relieved with defecation, absence of weight loss, blood in stools, or nocturnal symptoms, along with normal physical examination and routine blood tests, are indicative of irritable bowel syndrome (IBS). IBS is a functional gastrointestinal disorder characterized by abdominal pain or discomfort and altered bowel habits in the absence of any organic cause. It is a diagnosis of exclusion made based on symptom criteria, and the provided clinical scenario aligns with the typical presentation of IBS.

5. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.
