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."
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.
