1. Which of the following is a chronic inflammatory disease of the airways that causes episodes of wheezing, breathlessness, chest tightness, and coughing?

• A. Asthma
• B. Bronchitis
• C. Pneumonia
• D. Emphysema

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic inflammatory disease of the airways characterized by episodes of wheezing, breathlessness, chest tightness, and coughing. These symptoms are often triggered by allergens or exercise. Bronchitis is an inflammation of the bronchial tubes, but it is not typically chronic or involve the same triggers as asthma. Pneumonia is an infection of the lungs, and emphysema is a type of chronic obstructive pulmonary disease (COPD) often caused by smoking.

2. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?

• A. Corticosteroid
• B. Bronchodilator
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.

3. The nurse is giving digoxin to a client. What is the most important parameter to check before administration?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, an abnormally slow heart rate. Monitoring the heart rate is essential to prevent potential complications associated with digoxin therapy. Choices B, C, and D are less critical parameters to assess before administering digoxin. While blood pressure is also important to monitor during digoxin therapy, the most crucial parameter to check due to the medication's potential effect on heart rate is the heart rate itself.

4. Which medication is used to lower high blood pressure and reduce the risk of heart attacks and strokes?

• A. ACE inhibitor
• B. Beta-blocker
• C. Diuretic
• D. Calcium channel blocker

Correct answer: A

Rationale: The correct answer is an ACE inhibitor. ACE inhibitors are medications specifically designed to lower high blood pressure and reduce the risk of heart attacks, strokes, and other cardiovascular events. Beta-blockers, diuretics, and calcium channel blockers are also used to treat high blood pressure, but ACE inhibitors are particularly effective in reducing the risk of heart attacks and strokes.

5. What is a severe and often sudden allergic reaction that can lead to breathing difficulties and anaphylactic shock?

• A. Anaphylaxis
• B. Allergic rhinitis
• C. Bronchospasm
• D. Asthma attack

Correct answer: A

Rationale: Anaphylaxis is the correct answer. It is a severe allergic reaction that can result in difficulty breathing, a drop in blood pressure, and even anaphylactic shock if not treated promptly. Choice B, allergic rhinitis, is characterized by symptoms such as a runny or stuffy nose, sneezing, and itching. Choice C, bronchospasm, refers to the sudden constriction of the muscles in the walls of the bronchioles, leading to breathing difficulties. Choice D, asthma attack, involves the inflammation and narrowing of the airways, resulting in symptoms like wheezing, coughing, and chest tightness.
