Question

Prior to undergoing Pulmonary Function Tests (PFTs), it is essential to:

a) Fast for 12 hours
b) Perform deep breathing exercises
c) Avoid caffeine consumption
d) Administer a bronchodilator

Answer 1

To ensure accurate results in Pulmonary Function Tests (PFTs), it is important to avoid caffeine consumption.

Step-by-step explanation:

Prior to undergoing Pulmonary Function Tests (PFTs), it is essential to avoid caffeine consumption. This is because caffeine can stimulate the central nervous system and affect respiratory function, which may interfere with the accuracy of the test results. By avoiding caffeine, the patient ensures that their respiratory function is not artificially altered, allowing the PFTs to provide an accurate assessment of their lung health.
