Nursing Elites

1. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.

2. A client with hypothyroidism is started on levothyroxine (Synthroid). Which statement by the client indicates a need for further teaching?

• A. I will take this medication every morning before breakfast.
• B. I should have my thyroid levels checked regularly.
• C. If I lose weight, I may need an increased dose.
• D. I can stop taking this medication once my symptoms improve.

Correct answer: D

Rationale: The correct answer is D. Levothyroxine is typically a lifelong therapy for hypothyroidism. It should not be discontinued even if symptoms improve because the medication helps replace the deficient thyroid hormone. Stopping the medication prematurely can lead to a recurrence of symptoms and potential complications. Patients must understand the importance of continuous levothyroxine therapy and the necessity of regular follow-up with their healthcare provider to monitor thyroid levels and adjust the dosage as needed.

3. What instruction should the nurse include in the discharge teaching for a patient with hypothyroidism prescribed levothyroxine?

• A. Take the medication with meals.
• B. Take the medication in the morning on an empty stomach.
• C. Discontinue the medication if you feel better.
• D. Double the dose if a dose is missed.

Correct answer: B

Rationale: The correct instruction for a patient with hypothyroidism prescribed levothyroxine is to take the medication in the morning on an empty stomach to enhance absorption. Taking it with meals can interfere with absorption. Patients should not discontinue the medication without consulting their healthcare provider as it can lead to adverse effects. Doubling the dose if a dose is missed can increase the risk of side effects and overdosage. It is crucial for patients to follow the prescribed dosing schedule and consult their healthcare provider for any concerns or missed doses.

4. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

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

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

5. 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.
