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. The community health nurse is working in a multi-ethnic health center. In what situation should the nurse intervene?

• A. An Asian-American mother reports using cupping to treat an infection, resulting in a pattern of red round marks on her toddler's back.
• B. A Hispanic pregnant client who is often late for appointments arrives late for today's appointment.
• C. A Native-American individual being interviewed will not make direct eye contact when asked about violence in the home.
• D. An African-American infant who is spitting up milk has lost 6 ounces since last week's clinic visit.

Correct answer: D

Rationale: The correct answer is D because losing weight in an infant, especially when combined with spitting up milk, requires immediate intervention to address potential health concerns. Choice A deals with a cultural practice that may not necessarily pose an immediate health risk. Choice B, while important, does not present an immediate health threat. Choice C relates to cultural differences in communication and does not necessarily indicate a need for immediate intervention in terms of health.

3. A client with type 2 diabetes mellitus presents to the clinic with a foot ulcer. Which instruction should the nurse provide to the client to promote healing of the ulcer?

• A. Apply a heating pad to the ulcer twice daily.
• B. Wear tight-fitting shoes to protect the ulcer.
• C. Keep the ulcer clean and dry.
• D. Limit walking to reduce pressure on the ulcer.

Correct answer: C

Rationale: The correct answer is C: "Keep the ulcer clean and dry." For clients with diabetes mellitus, it is crucial to maintain foot ulcers clean and dry to prevent infection and promote healing. Moist environments can lead to bacterial growth and delay healing. Applying a heating pad (Choice A) can increase the risk of burns and further damage the ulcer. Wearing tight-fitting shoes (Choice B) can cause friction and pressure on the ulcer, hindering the healing process. Limiting walking (Choice D) excessively can affect circulation and delay healing. Therefore, the nurse should instruct the client to keep the ulcer clean and dry for optimal wound care management.

4. A client receiving total parenteral nutrition (TPN) through a central line suddenly develops dyspnea, chest pain, and a drop in blood pressure. What should the nurse do first?

• A. Stop the TPN infusion.
• B. Notify the healthcare provider.
• C. Place the client in Trendelenburg position.
• D. Administer oxygen at 2 liters/minute.

Correct answer: C

Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.

5. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.
