A nurse is teaching an adolescent how to use a peak expiratory flow meter (PEFM). The nurse should identify that which of the following statements by the child indicates an understanding of the teaching?
"I will breathe in through the mouthpiece, hold my breath for 5 seconds, and then exhale."
"If I get a reading in the green zone, I will tell my parents right away so they can call the doctor."
"I will slowly exhale through the mouthpiece over a 10-second interval."
"I will record the highest reading of the three attempts."
The Correct Answer is D
A. "I will breathe in through the mouthpiece, hold my breath for 5 seconds, and then exhale.": Incorrect because the child should exhale forcefully and quickly into the device, not inhale or hold their breath.
B. "If I get a reading in the green zone, I will tell my parents right away so they can call the doctor.": Incorrect because a green zone reading indicates controlled asthma, and no immediate action is required.
C. "I will slowly exhale through the mouthpiece over a 10-second interval.": Incorrect because the exhalation should be rapid and forceful to measure peak flow effectively.
D. "I will record the highest reading of the three attempts." Recording the highest reading ensures accurate monitoring of airway status and helps the child track their progress over time.
