Question 1 of 5
A client who suffers from severe persistent allergic asthma is prescribed omalizumab (Xolair). Which statement below correctly describes the mechanism of action associated with omalizumab (Xolair)?
Correct Answer: C
Rationale: Omalizumab binds to immunoglobulin E (IgE), preventing it from attaching to mast cells and basophils, thus reducing the release of allergic mediators that contribute to asthma attacks.
Question 2 of 5
A client presents to the healthcare setting with a diagnosis of emphysema. Which of the following medications below would be contraindicated with the client's allergy to soybeans?
Correct Answer: C
Rationale: Ipratropium bromide contains soy lecithin, which is contraindicated for clients with soybean allergies.
Question 3 of 5
A client frequently takes diphenhydramine (Benadryl) to alleviate his upper respiratory symptoms associated with allergies. Which of the following mechanism of actions applies to diphenhydramine (Benadryl)?
Correct Answer: B
Rationale: Diphenhydramine is an antihistamine that competes with histamine for binding to H1 receptor sites, effectively reducing symptoms of allergies, such as sneezing, itching, and nasal congestion.
Question 4 of 5
The nurse is preparing to administer albuterol to a client experiencing an acute asthma attack. Which medication on the client's medical record is a direct contraindication to albuterol administration?
Correct Answer: A
Rationale: Beta-blockers antagonize the bronchodilatory effects of albuterol, a beta-agonist, potentially worsening asthma symptoms.
Question 5 of 5
A client is being discharged with a cromolyn (Intal) inhaler to assist in the treatment of asthma. The nurse should include which information in the discharge teaching for this medication?
Correct Answer: A
Rationale: Cromolyn is a mast cell stabilizer that helps prevent asthma symptoms by inhibiting the release of inflammatory mediators. Using it before physical activity can help minimize exercise-induced bronchospasm.
