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 D
Explanation
A. Administer IV antibiotics: While urgent, antibiotics can be administered after precautions are in place to ensure safety.
B. Monitor vital signs: Important but not the first action. Vital signs can be monitored after precautions are initiated.
C. Encourage oral fluids: Incorrect because IV fluids are usually required due to the severity of the illness and risk of shock.
D. Initiate droplet precautions. Protecting others from transmission is the highest priority in managing bacterial meningitis, a highly contagious condition.
Correct Answer is C
Explanation
A. Educate the infant's caregiver about the feeding: While important, education should occur after ensuring the prescription is correct.
B. Flush the feeding tube before the feeding: This ensures patency but should only be done after verifying the prescription.
C. Clarify the feeding prescription with the provider. Bolus feedings are typically contraindicated with nasojejunal tubes because the jejunum cannot handle large volumes at once. Continuous feedings are usually prescribed. The prescription should be clarified before proceeding.
D. Place a label on the feeding bag and tubing: Labeling is necessary for safety but is not the priority when the prescription may be inappropriate.
