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 with a history of myocardial infarction (MI) is prescribed nitroglycerin (Nitrostat) for chest pain. Which instruction should the nurse provide?

• A. Take the medication with food.
• B. Swallow the tablet whole.
• C. Take the medication at bedtime.
• D. Place the tablet under your tongue.

Correct answer: D

Rationale: The correct instruction for a client prescribed nitroglycerin (Nitrostat) for chest pain is to place the tablet under the tongue. This route allows for rapid absorption of the medication, providing quick relief for chest pain associated with myocardial infarction.

3. A client with coronary artery disease (CAD) is prescribed atorvastatin (Lipitor). Which laboratory value requires immediate intervention?

• A. Total cholesterol of 180 mg/dL.
• B. Low-density lipoprotein (LDL) of 200 mg/dL.
• C. Triglycerides of 150 mg/dL.
• D. High-density lipoprotein (HDL) of 40 mg/dL.

Correct answer: B

Rationale: An LDL level of 200 mg/dL is significantly elevated and requires immediate intervention to reduce the risk of cardiovascular events in a client with coronary artery disease (CAD). High LDL levels contribute to the development and progression of atherosclerosis, which can lead to complications like heart attacks and strokes. Lowering LDL levels is a key goal in managing CAD and preventing further cardiovascular damage. Total cholesterol of 180 mg/dL, triglycerides of 150 mg/dL, and HDL of 40 mg/dL are within acceptable ranges and do not pose an immediate risk that necessitates urgent intervention.

4. The healthcare provider is caring for a client with a chest tube. Which assessment finding requires immediate intervention?

• A. Intermittent bubbling in the water seal chamber.
• B. Drainage of 75 ml in the first hour post-insertion.
• C. Crepitus around the insertion site.
• D. Fluctuation of the water level in the water seal chamber with respiration.

Correct answer: C

Rationale: Crepitus (subcutaneous emphysema) around the insertion site can indicate air leakage, requiring immediate intervention to prevent complications such as pneumothorax. This assessment finding suggests that there may be a break in the chest tube system, leading to air entering the pleural space. Prompt intervention is crucial to prevent respiratory compromise and further complications.

5. What nursing intervention can help alleviate pruritus in a client with cirrhosis?

• A. Administering antihistamines
• B. Providing a high-protein diet
• C. Applying emollients to the skin
• D. Encouraging frequent baths with hot water

Correct answer: C

Rationale: Applying emollients to the skin can help alleviate pruritus in clients with cirrhosis. Emollients help soothe and moisturize the skin, reducing the discomfort associated with itching.
