1. For a patient with asthma, what is the primary purpose of prescribing montelukast?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: Montelukast, a leukotriene receptor antagonist, is primarily prescribed to prevent asthma attacks. It works by reducing inflammation and bronchoconstriction in the airways, thereby helping to control asthma symptoms and prevent exacerbations.

2. 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.

3. During the initial assessment of a client with a history of substance abuse admitted for detoxification, which intervention is most important?

• A. Obtain a detailed substance use history.
• B. Establish a trusting nurse-client relationship.
• C. Evaluate the client's physical health status.
• D. Determine the client's readiness for change.

Correct answer: C

Rationale: Assessing the client's physical health status is the most critical intervention during the initial assessment of a client with a history of substance abuse admitted for detoxification. This evaluation helps identify and address any immediate health risks, such as withdrawal symptoms or medical complications, to ensure the client's safety and well-being during the detoxification process. Option A, obtaining a detailed substance use history, is important but not the most critical initially. Option B, establishing a trusting nurse-client relationship, is important but assessing physical health takes precedence. Option D, determining the client's readiness for change, is valuable but assessing physical health for immediate risks is the priority.

4. A client has been diagnosed with an esophageal diverticulum after undergoing diagnostic imaging. When taking the health history, the nurse should expect the client to describe what sign or symptom?

• A. Burning pain on swallowing
• B. Regurgitation of undigested food
• C. Symptoms mimicking a myocardial infarction
• D. Chronic parotid abscesses

Correct answer: B

Rationale: Regurgitation of undigested food is a typical symptom of esophageal diverticulum. This condition forms a pouch in the esophagus that can trap food, leading to regurgitation of undigested food. The other options are not typically associated with esophageal diverticulum.

5. While assessing a client with preeclampsia who is receiving magnesium sulfate, the nurse notes her deep tendon reflexes are 1+, respiratory rate is 12 breaths/minute, urinary output is 90 ml in 4 hours, and magnesium sulfate level is 9 mg/dl. What intervention should the nurse implement based on these findings?

• A. Continue the magnesium sulfate infusion as prescribed.
• B. Decrease the magnesium sulfate infusion by one-half.
• C. Stop the magnesium sulfate infusion immediately.
• D. Administer calcium gluconate immediately.

Correct answer: C

Rationale: The nurse should stop the magnesium sulfate infusion immediately in a client with preeclampsia exhibiting diminished reflexes, respiratory depression, and low urinary output, which indicate magnesium sulfate toxicity. This action is crucial to prevent further complications and adverse effects on the client.
