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 male client is admitted to the neurological unit. He has just sustained a C-5 spinal cord injury. Which assessment finding of this client warrants immediate intervention by the nurse?

• A. Is unable to feel sensation in the arms and hands.
• B. Has flaccid upper and lower extremities.
• C. Blood pressure is 110/70 and the apical pulse is 68.
• D. Respirations are shallow, labored, and 14 breaths/minute.

Correct answer: D

Rationale: Respirations that are shallow, labored, and at 14 breaths/minute indicate potential respiratory compromise, which is a critical situation requiring immediate intervention to maintain adequate oxygenation and prevent respiratory failure.

3. A client with cirrhosis of the liver is experiencing pruritus. Which intervention should the nurse implement to help relieve the client's symptoms?

• A. Administer acetaminophen (Tylenol).
• B. Apply lotion to the skin.
• C. Encourage a high-protein diet.
• D. Provide a warm bath.

Correct answer: B

Rationale: Pruritus is a common symptom in clients with cirrhosis due to bile salts accumulating in the skin. Applying lotion to the skin helps soothe the itching and can prevent skin breakdown. Acetaminophen can worsen liver damage in clients with cirrhosis as it is metabolized in the liver. Encouraging a high-protein diet is not directly related to relieving pruritus. Providing a warm bath may further dry the skin, exacerbating the itching. Therefore, the most appropriate intervention to help relieve pruritus in a client with cirrhosis is to apply lotion to the skin.

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 28-year-old woman presents with abdominal pain, bloating, and diarrhea. She notes that her symptoms improve with fasting. She has a history of iron deficiency anemia. What is the most likely diagnosis?

• A. Irritable bowel syndrome
• B. Celiac disease
• C. Lactose intolerance
• D. Crohn's disease

Correct answer: B

Rationale: The symptoms of abdominal pain, bloating, diarrhea improving with fasting, and a history of iron deficiency anemia are characteristic of celiac disease. Celiac disease is an autoimmune disorder triggered by gluten consumption, leading to damage in the small intestine. The improvement with fasting may be due to the temporary avoidance of gluten-containing foods. Irritable bowel syndrome, lactose intolerance, and Crohn's disease do not typically present with improvement of symptoms with fasting or have a clear association with iron deficiency anemia.
