Nursing Elites

1. A client with a new diagnosis of myasthenia gravis is prescribed pyridostigmine (Mestinon). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to prevent gastrointestinal upset.
• B. Take the medication 30 minutes before meals.
• C. Avoid dairy products while taking this medication.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct instruction for a client with myasthenia gravis prescribed pyridostigmine (Mestinon) is to take the medication 30 minutes before meals. This timing is crucial as it helps improve muscle strength for eating and swallowing. By taking the medication before meals, the client can experience enhanced muscle function during mealtime, which is especially important for managing the symptoms of myasthenia gravis. Choices A, C, and D are incorrect. Taking the medication with food may decrease its effectiveness, avoiding dairy products is not necessary, and taking the medication at bedtime does not coincide with the optimal timing for enhancing muscle function during meals.

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. 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.

4. A client with chronic obstructive pulmonary disease (COPD) is experiencing respiratory distress. Which intervention should the nurse implement first?

• A. Administer bronchodilators as prescribed.
• B. Encourage pursed-lip breathing.
• C. Position the client in a high Fowler's position.
• D. Obtain a stat arterial blood gas (ABG) sample.

Correct answer: C

Rationale: In a client with COPD experiencing respiratory distress, the priority intervention should be to position the client in a high Fowler's position. This position helps optimize lung expansion, improve oxygenation, and reduce the work of breathing. Administering bronchodilators and encouraging pursed-lip breathing are important interventions but positioning the client to enhance respiratory function takes precedence in this situation. Obtaining an ABG sample may provide valuable information but is not the initial priority when addressing respiratory distress.

5. A 35-year-old woman presents with abdominal pain, diarrhea, and weight loss. She has a history of recurrent mouth ulcers and a perianal fistula. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Crohn's disease
• D. Diverticulitis

Correct answer: C

Rationale: The combination of symptoms including recurrent mouth ulcers, perianal fistula, abdominal pain, diarrhea, and weight loss strongly suggests Crohn's disease. These extra-intestinal manifestations are characteristic of Crohn's disease, a chronic inflammatory condition that can affect any part of the gastrointestinal tract. Ulcerative colitis primarily involves the colon, while irritable bowel syndrome is a functional disorder without the inflammatory component seen in Crohn's disease. Diverticulitis typically presents with localized left lower quadrant pain and is less likely to cause mouth ulcers and perianal fistulas.
