A client with suspected asthma is discussing diagnostic tests with a nurse. The client asks about the purpose of a bronchial provocation test. What should the nurse explain?

"This test measures oxygen levels in your blood."

"It assesses your lung function and airflow response to various substances."

"It helps to visualize your airways using a special camera."

"This test checks for the presence of specific antibodies related to asthma."

Answer and Explanation

The Correct Answer is B

A) Incorrect. Measuring oxygen levels in the blood is typically done using pulse oximetry or arterial blood gas tests, not a bronchial provocation test.

B) Correct. A bronchial provocation test evaluates how the airways respond to substances that can trigger bronchoconstriction, helping to diagnose asthma.

C) Incorrect. Visualizing airways using a special camera is usually done through bronchoscopy, not a bronchial provocation test.

D) Incorrect. Checking for specific antibodies related to asthma is not a primary diagnostic test for asthma; it is more commonly associated with allergies.

Correct Answer is B

Explanation

A) Incorrect. Bronchial smooth muscle is involved in asthma, particularly in airway constriction.

B) Correct. In asthma, bronchial smooth muscle contracts and narrows the airways, contributing to symptoms like wheezing and shortness of breath.

C) Incorrect. Bronchial smooth muscle's primary role in asthma is not to clear mucus from the airways.

D) Incorrect. Bronchial smooth muscle does not release antibodies to protect against asthma attacks.

A. "You should use your rescue inhaler once a day to prevent symptoms." B. "Use it only when you have difficulty breathing during exercise." C. "Use your rescue inhaler when you experience asthma symptoms or as directed by your healthcare provider." D. "It's best to use your rescue inhaler before bedtime for a good night's sleep."

Correct Answer is C

Explanation

A) Incorrect. Rescue inhalers are typically not used as a daily preventive measure but are reserved for acute symptom relief.

B) Incorrect. While exercise-induced asthma is a valid reason to use a rescue inhaler, it should also be used when experiencing other asthma symptoms.

C) Correct. Rescue inhalers are meant for quick relief during asthma symptoms or exacerbations, and their use should be guided by symptoms or healthcare provider instructions.

D) Incorrect. There is no specific benefit to using a rescue inhaler before bedtime unless asthma symptoms are present at that time.
