A nurse is instructing a school-age child who has asthma about the use of a peak expiratory flow meter.
Which of the following instructions should the nurse include in the teaching?
Maintain a semi-Fowler’s position during testing
Place tongue on the mouthpiece of the meter
Blow into the meter as hard and quickly as possible
Record the average of the readings
The Correct Answer is C
The correct answer is choice C. Blow into the meter as hard and quickly as possible.
This is because a peak flow meter measures how fast you can push air out of your lungs when you blow out as hard and as fast as you can.
This is called peak expiratory flow rate (PEFR) or peak expiratory flow (PEF). It shows how open the airways are in the lungs and can help detect early signs of worsening asthma.
Choice A is wrong because maintaining a semi-Fowler’s position during testing is not necessary. You can sit or stand up straight, but make sure you do it the same way each time.
Choice B is wrong because placing tongue on the mouthpiece of the meter can block the air flow and affect the accuracy of the measurement. You should close your lips tightly on the mouthpiece instead.
Choice D is wrong because recording the average of the readings is not recommended.
You should record the highest of the three readings on a sheet of paper, calendar or in your asthma diary. This is your daily peak flow.
Normal ranges for peak flow vary depending on age, height, gender and race. You can use a chart or calculator to find out your predicted normal peak flow based on these factors. However, it is more important to find out your personal best peak flow by performing peak flow testing twice a day for two weeks when your asthma is under good control. Your personal best peak flow will be used to create your asthma action plan with your healthcare provider.

Correct Answer is D
Explanation
Hypertonicity is a sign of increased muscle tone and stiffness, which can indicate that the newborn is experiencing withdrawal from methadone exposure in utero. Methadone is an opioid medication that can cross the placenta and cause neonatal abstinence syndrome (NAS) in the newborn.
Choice A, acrocyanosis, is wrong because it is a normal finding in newborns.
Acrocyanosis is a bluish discoloration of the hands and feet due to immature peripheral circulation. It usually resolves within the first 24 to 48 hours of life.
Choice B, bradycardia, is wrong because it is not a typical sign of withdrawal.
Bradycardia is a slow heart rate, usually less than 100 beats per minute in newborns. It can be caused by hypoxia, hypothermia, hypoglycemia, or vagal stimulation.
Choice C, bulging fontanels, is wrong because it is a sign of increased intracranial pressure, not withdrawal. Bulging fontanels can be caused by meningitis, hydrocephalus, or hemorrhage.
Normal ranges for newborn vital signs are as follows:
- Heart rate: 120 to 160 beats per minute
- Respiratory rate: 30 to 60 breaths per minute
- Temperature: 36.5 to 37.5°C (97.7 to 99.5°F)
- Blood pressure: 60 to 80 mm Hg systolic and 40 to 50 mm Hg diastolic
Correct Answer is B
Explanation
Choice A reason
Administering naloxone to the newborn is not appropriate. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose in adults. It is not typically used for newborns with neonatal abstinence syndrome. The management of NAS is primarily supportive, and medications may be prescribed to help manage specific withdrawal symptoms, but naloxone is not a standard treatment for NAS.
Choice B reason:
Minimizing noise in the newborn's environment is a crucial action in the plan of care is the correct action to be included. Newborns experiencing NAS can be easily overstimulated, and loud noises can exacerbate their withdrawal symptoms and distress. Creating a calm and quiet environment helps reduce agitation and promotes better sleep and overall comfort.
Choice C reason
Swaddling the newborn with his leg extended is not appropriate in this case. Swaddling can be beneficial for some newborns, but the specific positioning and swaddling techniques should be individualized based on the newborn's needs and preferences. Extending the newborn's legs may not necessarily be the best approach, as it may not provide comfort or address the symptoms associated with NAS.
Choice D reason:
Maintaining eye contact with the newborn during feedings is not appropriate in this case. While maintaining eye contact during feedings is an essential aspect of bonding and promoting parent-newborn attachment, it may not be the primary focus in managing neonatal abstinence syndrome. The plan of care for a newborn with NAS would primarily involve managing withdrawal symptoms, providing comfort measures, and addressing the newborn's unique needs during this challenging period.
