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 65-year-old white female with a history of arthritis, congestive heart failure, and osteoporosis complains of odynophagia for two weeks. A barium swallow shows a moderate-sized crater just above the gastroesophageal junction. What is the least likely contributor to this condition?

• A. NSAIDs
• B. Alendronate
• C. Iron sulfate
• D. Calcium channel blocker

Correct answer: D

Rationale: In this case, the least likely contributor to the condition described is the calcium channel blocker. NSAIDs, alendronate, and iron sulfate have been associated with pill-induced esophagitis, which can present with symptoms like odynophagia and erosions or ulcers on imaging studies. Pill-induced esophagitis is often due to factors like inadequate water intake with the medication, being in a supine position, or underlying motility disorders. Discontinuation of the offending medication typically leads to rapid resolution of esophageal injury. Acid-suppressive therapy may be used to prevent reflux-related damage.

3. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

4. A client with type 1 diabetes mellitus is experiencing nausea and vomiting. What advice should the nurse give regarding insulin administration?

• A. Skip your insulin dose until you can eat.
• B. Take your insulin as prescribed, but monitor your blood glucose closely.
• C. Reduce your insulin dose by half.
• D. Only take your long-acting insulin.

Correct answer: B

Rationale: The correct advice for a client with type 1 diabetes mellitus experiencing nausea and vomiting is to take insulin as prescribed but monitor blood glucose closely. It is essential to continue insulin therapy even if not eating normally to prevent complications from high blood sugar levels. Skipping insulin doses can lead to dangerous fluctuations in blood glucose levels. Reducing the insulin dose without proper guidance can also result in uncontrolled blood sugar. Taking only long-acting insulin may not provide adequate coverage for mealtime blood sugar elevation. Therefore, the best course of action is to take prescribed insulin doses while closely monitoring blood glucose levels.

5. A male client in the day room becomes increasingly angry and aggressive when denied a day-pass. Which action should the nurse implement?

• A. Tell him he can have a day pass if he calms down.
• B. Put the client's behavior on extinction.
• C. Decrease the volume on the television set.
• D. Instruct the client to sit down and be quiet.

Correct answer: D

Rationale: Instructing the client to sit down and be quiet is a direct and assertive approach that can help de-escalate the situation safely. It sets clear boundaries and expectations for the client's behavior, which may help reduce agitation and aggression in this scenario. Offering a day pass if the client calms down (Choice A) might reinforce the aggressive behavior. Putting the client's behavior on extinction (Choice B) involves not reinforcing the behavior, but it may not directly address the immediate safety concern. Decreasing the volume on the television set (Choice C) does not address the client's behavior directly and may not effectively manage the escalating situation.
