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. What is the primary action of a short-acting beta2-agonist (SABA) prescribed to a patient with an acute asthma exacerbation?

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

Correct answer: B

Rationale: The correct answer is B: Relieve bronchospasm. The primary action of short-acting beta2-agonists (SABAs) is to relieve bronchospasm. These medications are bronchodilators that work by opening the airways, making breathing easier for patients experiencing asthma exacerbations. By relieving bronchospasm, SABAs help improve airflow and alleviate symptoms of asthma such as wheezing and shortness of breath. Choices A, C, and D are incorrect because SABAs do not primarily reduce inflammation, thin respiratory secretions, or suppress cough. While these actions may be part of asthma management, the immediate goal of using a SABA during an acute exacerbation is to quickly relieve bronchospasm and improve airflow.

3. A 45-year-old woman with occasional indigestion has had episodes of chest pain and dysphagia to both solids and liquids. An upper GI series and EGD fail to disclose any structural abnormalities. What is the most appropriate initial therapy?

• A. Sucralfate
• B. Proton pump inhibitor
• C. Prokinetic agent
• D. Benzodiazepine

Correct answer: B

Rationale: The patient's symptoms of chest pain and dysphagia suggest esophageal spasm, often related to underlying gastroesophageal reflux. The initial therapy should focus on acid suppression. Proton pump inhibitors are the preferred choice to reduce acid production and alleviate symptoms. If proton pump inhibitors are ineffective, other options like smooth muscle relaxants or antidepressants may be considered. A Heller myotomy is not indicated in this case as the patient does not have achalasia.

4. For a patient with asthma, what is the primary purpose of prescribing salmeterol?

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

Correct answer: B

Rationale: Salmeterol is classified as a long-acting beta2-agonist, which is used to prevent asthma attacks by providing extended bronchodilation. It is not typically used for immediate relief of acute bronchospasm or for suppressing cough. Additionally, salmeterol does not have the primary purpose of thinning respiratory secretions.

5. Which client's laboratory value requires immediate intervention by a nurse?

• A. A client with GI bleeding who is receiving a blood transfusion and has a hemoglobin of 7 grams.
• B. A client with pancreatitis who has a fasting glucose of 190 mg/dl today and had 160 mg/dl yesterday.
• C. A client with hepatitis who is jaundiced and has a bilirubin level that is 4 times the normal value.
• D. A client with cancer who has an absolute neutrophil count < 500 today and had 2,000 yesterday.

Correct answer: D

Rationale: The correct answer is D. A sudden drop in neutrophil count to below 500 indicates severe neutropenia, putting the client at high risk for infections. Neutrophils are essential for fighting off infections, and a significant decrease in their count can compromise the client's immune response. Immediate intervention is necessary to prevent the development of serious infections in the client with neutropenia.
