1. For a patient with asthma, what is the primary purpose of prescribing montelukast?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: Montelukast, a leukotriene receptor antagonist, is primarily prescribed to prevent asthma attacks. It works by reducing inflammation and bronchoconstriction in the airways, thereby helping to control asthma symptoms and prevent exacerbations.

2. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?

• A. Wilson's disease
• B. Hemochromatosis
• C. Alpha-1 antitrypsin deficiency
• D. Autoimmune hepatitis

Correct answer: B

Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.

3. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching?

• A. Avoid alcohol while taking this medication.
• B. Take the medication with a full meal.
• C. Increase your intake of high-fiber foods.
• D. Avoid exposure to sunlight.

Correct answer: A

Rationale: The correct instruction for the client prescribed with methotrexate is to avoid alcohol while taking this medication. Methotrexate can cause liver toxicity, and alcohol consumption can further exacerbate this risk. It is crucial for patients to abstain from alcohol to prevent adverse effects on the liver. Therefore, instructing the client to avoid alcohol is a key component of safe medication use and management of rheumatoid arthritis.

4. A patient with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium. What is the primary purpose of this medication?

• A. Reduce mucus production
• B. Relieve bronchospasm
• C. Suppress cough
• D. Thin respiratory secretions

Correct answer: B

Rationale: Tiotropium is a long-acting bronchodilator used to relieve bronchospasm and improve airflow in patients with chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles around the airways, leading to bronchodilation and improved breathing, making it an essential treatment in managing COPD symptoms.

5. 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.
