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.

Correct Answer is A
Explanation
A. "Maintain aseptic technique during the child's dressing changes." Aseptic technique reduces the risk of infection, which is critical for children with burns as their immune response may be compromised.
B. "Provide low-calorie snacks for the child several times each day." Children with burns require a high-calorie, high-protein diet to promote healing and compensate for increased metabolic demands.
C. "Apply continuous passive motion devices to the child's lower extremities during periods of rest." Passive motion devices are not typically indicated for burn injuries unless there is joint involvement requiring physical therapy for mobility restoration.
D. "Administer pain medication to the child 30 min following physical therapy." Pain medication should be administered before physical therapy to improve tolerance and participation.
Correct Answer is A
Explanation
A. Accompany verbal instructions with visual references. Children with ADHD benefit from multimodal teaching strategies. Combining verbal instructions with visual aids helps reinforce understanding and keeps the child focused.
B. Vary the classroom routine to keep the children interested: Children with ADHD thrive on consistency; frequent changes in routine can increase confusion and distractibility.
C. Limit presentation of subjects of interest to the afternoons: This is not evidence-based. Children’s ability to focus varies throughout the day, and important content should not be restricted to a specific time.
D. Increase classroom assignments to stimulate learning: Increasing workload can overwhelm a child with ADHD, leading to frustration and reduced engagement.
