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. A client with myelogenous leukemia is receiving an autologous bone marrow transplantation (BMT). What is the priority intervention that the nurse should implement when the bone marrow is repopulating?

• A. Administer sargramostim (Leukine, Prokine).
• B. Infuse PRBC and platelet transfusions.
• C. Give parenteral prophylactic antibiotics.
• D. Maintain a protective isolation environment.

Correct answer: D

Rationale: Maintaining a protective isolation environment is crucial during the repopulation of bone marrow post-transplant to reduce the risk of infections. The client's immune system is compromised during this period, making them highly susceptible to infections. By implementing protective isolation measures, the nurse can help prevent exposure to pathogens, safeguarding the client's health and supporting the success of the transplantation.

3. A client with Addison's disease is being treated with fludrocortisone (Florinef). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypernatremia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Fludrocortisone, such as Florinef, is a mineralocorticoid that promotes sodium retention and potassium excretion, which can lead to hypernatremia. Therefore, the nurse should closely monitor for hypernatremia when a client with Addison's disease is being treated with fludrocortisone. Hyperkalemia (Choice A) is incorrect because fludrocortisone promotes potassium excretion, leading to hypokalemia rather than hyperkalemia. Hyponatremia (Choice B) is incorrect as fludrocortisone promotes sodium retention. Hypocalcemia (Choice D) is unrelated to the action of fludrocortisone.

4. 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.

5. A 75-year-old patient is admitted for pancreatitis. Which tool would be the most appropriate for the nurse to use during the admission assessment?

• A. Drug Abuse Screening Test (DAST-10)
• B. Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar)
• C. Screening Test-Geriatric Version (SMAST-G)
• D. Mini-Mental State Examination

Correct answer: C

Rationale: The most appropriate tool for the nurse to use during the admission assessment of a 75-year-old patient admitted for pancreatitis is the Screening Test-Geriatric Version (SMAST-G). Since alcohol abuse is a common factor associated with pancreatitis, screening for alcohol use is crucial. The SMAST-G is a validated short-form alcoholism screening instrument tailored for older adults. If the patient screens positively on the SMAST-G, then the CIWA-Ar would be useful for further assessment. The Drug Abuse Screening Test (DAST-10) provides information on substance use in general, not specific to alcohol. The Mini-Mental State Examination is used to assess cognitive function, not alcohol abuse.
