1. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

2. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?

• A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
• B. Absent peristalsis and elevated LES pressure
• C. Absent peristalsis and decreased LES pressure
• D. Vigorous peristalsis and decreased LES pressure

Correct answer: C

Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.

3. A client with a newly created ileostomy has not had ostomy output for the past 12 hours and reports worsening nausea. What is the nurse's priority action?

• A. Facilitate a referral to the wound-ostomy-continence (WOC) nurse
• B. Report signs and symptoms of obstruction to the health care provider
• C. Encourage the client to mobilize to enhance mobility
• D. Contact the health care provider to obtain a swab of the stoma for culture

Correct answer: B

Rationale: The nurse's priority action in this situation is to report signs and symptoms of possible obstruction to the healthcare provider. Lack of ostomy output and worsening nausea can indicate a potential obstruction, which requires immediate attention and intervention to prevent complications.

4. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching?

• A. Avoid alcohol while taking this medication.
• B. Take the medication with a full meal.
• C. Increase your intake of high-fiber foods.
• D. Avoid exposure to sunlight.

Correct answer: A

Rationale: The correct instruction for the client prescribed with methotrexate is to avoid alcohol while taking this medication. Methotrexate can cause liver toxicity, and alcohol consumption can further exacerbate this risk. It is crucial for patients to abstain from alcohol to prevent adverse effects on the liver. Therefore, instructing the client to avoid alcohol is a key component of safe medication use and management of rheumatoid arthritis.

5. A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?

• A. Hypotension
• B. Gingival hyperplasia
• C. Bradycardia
• D. Hyperkalemia

Correct answer: B

Rationale: Gingival hyperplasia, or overgrowth of the gums, is a common side effect of phenytoin. Patients should maintain good oral hygiene to minimize this effect.
