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 in acute renal failure has a serum potassium level of 6.3 mEq/L. What intervention can the nurse expect the healthcare provider to prescribe?

• A. Nitrofurantoin (Macrodantin) orally.
• B. Erythropoietin (Epogen) intravenously.
• C. Kayexalate retention enema.
• D. Azathioprine (Imuran) orally.

Correct answer: C

Rationale: In acute renal failure with high serum potassium levels, the healthcare provider is likely to prescribe a Kayexalate retention enema. Kayexalate is a medication used to lower elevated potassium levels by promoting potassium excretion through the gastrointestinal tract, thus aiding in the management of hyperkalemia in clients with renal failure.

3. What should the nurse include in patient teaching for a patient prescribed ceftriaxone for bacterial pneumonia?

• A. Take the medication as prescribed.
• B. Expect urine color changes.
• C. Complete the full course of the antibiotic.
• D. Avoid dairy products during treatment.

Correct answer: C

Rationale: When educating a patient prescribed ceftriaxone for bacterial pneumonia, it is crucial to emphasize completing the full course of the antibiotic. Completing the full course helps ensure the infection is completely eradicated and reduces the risk of antibiotic resistance. Incomplete courses of antibiotics can lead to treatment failure and the development of resistant bacterial strains. Therefore, it is essential for patients to adhere to the prescribed treatment regimen to achieve optimal outcomes.

4. A patient is admitted with a diagnosis of myasthenia gravis. What symptom should the nurse expect to find during the assessment?

• A. Joint pain
• B. Muscle weakness
• C. Loss of sensation
• D. Severe headache

Correct answer: B

Rationale: Myasthenia gravis is a neuromuscular disorder characterized by muscle weakness and fatigue, especially in the voluntary muscles. Patients with myasthenia gravis commonly experience weakness in muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. This weakness typically worsens with activity and improves with rest. Joint pain, loss of sensation, and severe headaches are not typical symptoms of myasthenia gravis. Therefore, the correct answer is muscle weakness (choice B) as it aligns with the characteristic symptom of myasthenia gravis.

5. When a client expresses, 'I don't know how I will go on' while discussing feelings related to a recent loss, the nurse remains silent. What is the most likely reason for the nurse's behavior?

• A. The nurse is indicating disapproval of the statement.
• B. The nurse is showing respect for the client's loss.
• C. Silence is mirroring the client's sadness.
• D. Silence enables the client to contemplate what was expressed.

Correct answer: D

Rationale: In therapeutic communication, silence can offer the client an opportunity to process their emotions and thoughts. By remaining silent, the nurse provides a space for the client to reflect on their own words, facilitating deeper exploration and understanding of their feelings.
