Nursing Elites

1. 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.

2. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

3. A client with a severe head injury is admitted to the intensive care unit (ICU). Which finding should the nurse report to the healthcare provider immediately?

• A. Urine output of 100 mL/hour.
• B. Intracranial pressure (ICP) of 20 mm Hg.
• C. Respiratory rate of 12 breaths/minute.
• D. Mean arterial pressure (MAP) of 70 mm Hg.

Correct answer: B

Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.

4. Why is a client with ascites scheduled for a paracentesis procedure?

• A. To diagnose liver disease
• B. To relieve abdominal pressure
• C. To assess kidney function
• D. To reduce blood pressure

Correct answer: B

Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.

5. When teaching a client postoperative breathing techniques with an incentive spirometer (IS), what should the nurse encourage the client to do to maintain sustained maximal inspiration?

• A. Exhale forcefully into the tubing for 3 to 5 seconds.
• B. Inspire deeply and slowly over 3 to 5 seconds.
• C. Breathe into the spirometer using normal breath volumes.
• D. Perform IS breathing exercises every 6 hours.

Correct answer: B

Rationale: To maintain sustained maximal inspiration when using an incentive spirometer, the client should be encouraged to inspire deeply and slowly over 3 to 5 seconds. This technique aids in achieving the goal of sustained maximal inspiration, which is essential for postoperative respiratory recovery.
