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 with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to improve absorption.
• B. Avoid foods high in vitamin K.
• C. Take the medication at the same time each day.
• D. Increase your intake of high-potassium foods.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching regarding dabigatran (Pradaxa) is to take the medication at the same time each day. This ensures a consistent blood level and effectiveness of the medication, which is crucial in managing atrial fibrillation and preventing complications. It helps maintain a steady therapeutic effect and reduces the risk of erratic drug levels in the body.

3. The preceptor is orienting a new graduate nurse to the critical care unit. The preceptor asks the new graduate to state symptoms that most likely indicate the beginning of a shock state in a critically ill client. What findings should the new graduate nurse identify?

• A. Warm skin, hypertension, and constricted pupils.
• B. Bradycardia, hypotension, and respiratory acidosis.
• C. Mottled skin, tachypnea, and hyperactive bowel sounds.
• D. Tachycardia, mental status change, and low urine output.

Correct answer: D

Rationale: Tachycardia, mental status change, and low urine output are early indicators of shock. In a critically ill client, these findings suggest a decrease in tissue perfusion. Prompt recognition and intervention are crucial to prevent the progression of shock and its complications.

4. An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?

• A. Corticosteroids
• B. Gamma globulin
• C. Hepatitis B vaccine
• D. Fresh frozen plasma

Correct answer: B

Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection. Therefore, the correct choice is Gamma globulin as it can provide immediate passive immunity against hepatitis B.

5. A 65-year-old white female with a history of arthritis, congestive heart failure, and osteoporosis complains of odynophagia for two weeks. A barium swallow shows a moderate-sized crater just above the gastroesophageal junction. What is the least likely contributor to this condition?

• A. NSAIDs
• B. Alendronate
• C. Iron sulfate
• D. Calcium channel blocker

Correct answer: D

Rationale: In this case, the least likely contributor to the condition described is the calcium channel blocker. NSAIDs, alendronate, and iron sulfate have been associated with pill-induced esophagitis, which can present with symptoms like odynophagia and erosions or ulcers on imaging studies. Pill-induced esophagitis is often due to factors like inadequate water intake with the medication, being in a supine position, or underlying motility disorders. Discontinuation of the offending medication typically leads to rapid resolution of esophageal injury. Acid-suppressive therapy may be used to prevent reflux-related damage.
