Standardized procedures with validation and audits ensure data remains accurate, consistent, and trustworthy.

Question 12: A peak flow meter shows readings 15% below the lab spirometer for the same patient. What is the most appropriate first action?

Document the discrepancy and proceed
Recalibrate or replace the peak flow meter (Correct answer)
Retest the patient on the spirometer
Attribute the difference to patient effort

Correct answer: Recalibrate or replace the peak flow meter

A consistent 15% discrepancy suggests instrument error; the peak flow meter should be checked against a reference or replaced before relying on its readings.
