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. An older adult with a diagnosis of Alzheimer's disease has been experiencing fecal incontinence, with no recent change in stool character noted by the nurse. What is the nurse's most appropriate intervention?

• A. Keep a food diary to identify foods that worsen the client's symptoms
• B. Provide the client with a bland, low-residue diet
• C. Toilet the client on a frequent, scheduled basis
• D. Collaborate with the primary provider to secure an order for loperamide

Correct answer: C

Rationale: The most appropriate intervention for an older adult with Alzheimer's disease experiencing fecal incontinence and no change in stool character is to toilet the client on a frequent, scheduled basis. Scheduled toileting can help manage incontinence by establishing a routine for bowel movements, which may aid in reducing episodes of fecal incontinence.

3. A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: Patients prescribed methotrexate should be advised to take folic acid supplements as prescribed. Methotrexate can deplete folic acid levels, leading to side effects. By taking folic acid supplements as directed, the patient can reduce the risk of experiencing adverse effects associated with methotrexate therapy. It is important to note that the effects of methotrexate may not be immediate, so realistic expectations should be set with the patient. Alcohol should be avoided while taking methotrexate due to potential interactions and increased risk of liver toxicity. There is no specific recommendation to limit fluid intake to 1 liter per day in relation to methotrexate therapy.

4. A 35-year-old male patient presents with right upper quadrant pain, fever for the past 48 hours, preceded by new onset jaundice over the past few weeks. He states that he has had diarrhea on and off for several years but never had this investigated. A liver ultrasound is negative for gallstones or evidence of cholecystitis. His lab tests reveal total bilirubin 6.2, alkaline phosphatase 450, AST 150, ALT 120, albumin 2.6. The next diagnostic test of choice would be

• A. Liver biopsy
• B. Magnetic resonance cholangiopancreatography
• C. Hepatitis B surface antigen and hepatitis C RNA assay
• D. Colonoscopy with biopsies

Correct answer: B

Rationale: The patient's presentation with right upper quadrant pain, fever, and jaundice, along with abnormal liver function tests, suggests a biliary tract problem. Given the suspicion of obstructed bile flow and the negative liver ultrasound for gallstones, magnetic resonance cholangiopancreatography (MRCP) is the next appropriate step to evaluate the biliary system and pancreatic ducts. MRCP is non-invasive and can provide detailed images for diagnosis. Liver biopsy is not the preferred initial diagnostic test in this context. Testing for hepatitis B and C would not address the current clinical scenario, and colonoscopy is not indicated for the presenting symptoms.

5. A client is receiving chemotherapy and is at risk for neutropenia. Which precaution should the nurse implement?

• A. Encourage regular visitors to boost morale.
• B. Ensure the client receives live vaccines.
• C. Place the client in a private room.
• D. Provide a diet high in fresh fruits and vegetables.

Correct answer: C

Rationale: Placing the client in a private room is crucial to protect them from infections due to their compromised immune system. Neutropenia, a common side effect of chemotherapy, decreases white blood cell count, making the client more susceptible to infections. By placing the client in a private room, exposure to pathogens from other individuals is minimized, reducing the risk of infection and helping maintain the client's health during this vulnerable period.
