Answer 1

In preparation for Pulmonary Function Tests (PFTs), patients are typically required to refrain from using bronchodilators and smoking for 4-6 hours to ensure accurate results.

Step-by-step explanation:

Before going for Pulmonary Function Tests (PFTs), a patient's bronchodilators will generally be withheld, and they are advised not to smoke for at least 4-6 hours prior to the test. These restrictions are important to ensure that the test results accurately reflect the patient's lung function without the influence of medications or recent smoking, which could alter lung function and lead to inaccurate test results.
