1. Which of the following statements is true about ischemic colitis?

• A. Typically requires colonic resection
• B. Affects the watershed areas of the colon, namely, the splenic flexure, right colon, and rectum
• C. Is only seen in the elderly
• D. Requires colonoscopic intervention

Correct answer: B

Rationale: Ischemic colitis most often results from low-flow states associated with hypotension or poor perfusion. As a result, the vascular watershed areas of the colon, including the splenic flexure, right colon, and rectum, are at highest risk of ischemic injury. Therefore, option B is correct as it accurately identifies the areas commonly affected by ischemic colitis.

2. What instruction should a patient with a history of hypertension be provided when being discharged with a prescription for a thiazide diuretic?

• A. Avoid foods high in potassium.
• B. Take the medication at bedtime.
• C. Monitor weight daily.
• D. Limit fluid intake to 1 liter per day.

Correct answer: C

Rationale: The correct instruction for a patient with a history of hypertension being discharged with a prescription for a thiazide diuretic is to monitor weight daily. This is important because thiazide diuretics can cause fluid imbalances, and monitoring weight daily can help detect significant changes early. Choice A, avoiding foods high in potassium, is not directly related to thiazide diuretics. Choice B, taking the medication at bedtime, may vary depending on the specific medication but is not a universal instruction. Choice D, limiting fluid intake to 1 liter per day, is not appropriate as adequate hydration is important to prevent complications like hypokalemia.

3. 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.

4. A patient with schizophrenia is prescribed olanzapine. What is an important side effect for the healthcare provider to monitor?

• A. Hypertension
• B. Weight gain
• C. Hypoglycemia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Weight gain. Olanzapine, an atypical antipsychotic, is known to cause significant weight gain and metabolic syndrome. It is crucial for healthcare providers to closely monitor patients for these side effects to prevent complications and provide appropriate interventions.

5. What instruction should be provided to a client with a history of myocardial infarction (MI) who is prescribed nitroglycerin?

• A. Take nitroglycerin with food to avoid stomach upset.
• B. Store nitroglycerin tablets in a dark, glass container.
• C. Swallow nitroglycerin tablets whole without chewing.
• D. Discontinue the medication if a headache occurs.

Correct answer: B

Rationale: Nitroglycerin is a medication that should be stored in a dark, glass container to protect it from light and moisture. Exposure to light and moisture can reduce its effectiveness. Storing it in a dark, glass container helps maintain the medication's stability and potency, ensuring that it remains safe and effective for use in emergencies, such as angina attacks.
