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 chronic pain is prescribed a fentanyl (Duragesic) patch. Which instruction should the nurse provide to the client?
- A. Apply the patch to a clean, dry, and hairless area of the skin.
- B. Use a heating pad over the patch to enhance absorption.
- C. Change the patch daily to maintain effectiveness.
- D. Place the patch on the same site with each application.
Correct answer: A
Rationale: The correct instruction for applying a fentanyl (Duragesic) patch is to place it on a clean, dry, and hairless area of the skin. This ensures proper adhesion of the patch and optimal absorption of the medication. Using a heating pad over the patch is contraindicated as it can increase drug absorption and lead to overdose. Changing the patch daily is necessary for some medications, but fentanyl patches are usually changed every 72 hours to maintain a steady blood level of the medication. Placing the patch on the same site with each application can lead to skin irritation, uneven drug absorption, and should be avoided to allow the skin to recover between applications.
4. 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.
5. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?
- A. Serum amylase.
- B. Serum sodium.
- C. Serum calcium.
- D. Serum potassium.
Correct answer: A
Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.
