Nursing Elites

1. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

2. A client who is 2 days postoperative reports severe pain and swelling in the right leg. The nurse notes that the leg is warm and red. What is the nurse's priority action?

• A. Apply a warm compress to the affected leg.
• B. Elevate the leg on pillows.
• C. Measure the circumference of the leg.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The nurse's priority action in this situation is to notify the healthcare provider immediately. These symptoms, including severe pain, swelling, warmth, and redness in the leg, are indicative of deep vein thrombosis (DVT), a potentially serious condition. Prompt notification of the healthcare provider is crucial to initiate appropriate diagnostic tests and interventions to prevent complications associated with DVT. Applying a warm compress (Choice A) could worsen the condition by increasing blood flow. Elevating the leg (Choice B) might be contraindicated in DVT as it can dislodge a clot. Measuring the circumference of the leg (Choice C) is not the priority at this time compared to promptly involving the healthcare provider.

3. When implementing patient teaching for a patient admitted with hyperglycemia and newly diagnosed diabetes mellitus scheduled for discharge the second day after admission, what is the priority action for the nurse?

• A. Instruct about the increased risk of cardiovascular disease.
• B. Provide detailed information about dietary glucose control.
• C. Teach glucose self-monitoring and medication administration.
• D. Give information about the effects of exercise on glucose control.

Correct answer: C

Rationale: The priority action for the nurse when time is limited is to focus on essential teaching. In this scenario, the patient should be educated on how to self-monitor glucose levels and administer medications to control glucose levels. This empowers the patient with immediate skills for managing their condition. Instructing about the increased risk of cardiovascular disease (choice A) is important but not as urgent as teaching self-monitoring and medication administration. Providing detailed information about dietary glucose control (choice B) can be beneficial but is secondary to ensuring the patient can monitor and manage their glucose levels. Teaching about the effects of exercise (choice D) is relevant but not as critical as immediate self-monitoring and medication administration education.

4. 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.

5. A patient with coronary artery disease (CAD) is prescribed a statin medication. What should the nurse include in the patient education?

• A. Take the medication with food.
• B. Report any muscle pain or weakness.
• C. Increase intake of grapefruit juice.
• D. Avoid foods high in potassium.

Correct answer: B

Rationale: Patients prescribed statin medications should be educated to report any muscle pain or weakness to their healthcare provider promptly. Muscle pain or weakness could be a sign of rhabdomyolysis, a serious side effect associated with statin use that requires medical attention. Choices A, C, and D are incorrect. Taking statins with food or increasing grapefruit juice intake are not necessary recommendations. Avoiding foods high in potassium is also not directly related to statin use.
