Explanation
Choice D is correct. The child's highest reading out of three times should be recorded (not the average). It is important that between each measurement, a 30-second rest is taken by the child.
Choice A is incorrect. Before the child measures their peak flow, the device should be reset by sliding the marker (or arrow) on the meter by placing it at the bottom of the numbered scale.
Choice B is incorrect. The child should not be sitting for this measurement; rather, they should be standing upright to allow for maximum chest expansion.
Choice C is incorrect. The peak flow meter measures expiratory volume, so the child should be instructed to blow as hard and quickly as possible.

Additional Info
✓ Use of a Peak Expiratory Flow Meter
1. Before each use, make certain the sliding marker or arrow on the peak expiratory flow meter is at the bottom of the numbered scale.
2. Stand up straight.
3. Remove gum or food from your mouth.
4. Close your lips tightly around the mouthpiece. Be certain to keep your tongue away from the mouthpiece.
5. Blow out as hard and as quickly as you can, a “fast, hard puff.”
6. Note the number by the marker on the numbered scale.
7. Repeat entire routine three times, but wait at least 30 seconds between each routine.
8. Record the highest of the three readings, not the average.
9. Measure your peak expiratory flow rate (PEFR) close to the same time and same way each day (e.g., morning and evening; before and 15 minutes after taking medication).
10. Keep a record of your PEFRs.
✓ Emphasize the importance of regularly monitoring peak flow as part of the child's asthma management plan. This helps track changes in lung function and enables timely intervention.
✓ Reinforce the importance of medication adherence as prescribed by the healthcare provider. Proper use of controller and rescue medications is crucial for maintaining asthma control.
