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 A
Explanation
The correct answer is choice A. The nurse should ensure the state health department has been notified of the child’s Lyme disease, as it is a reportable disease in most states.
Reporting helps to monitor the incidence and prevalence of Lyme disease and to implement prevention and control measures.
Choice B is wrong because antitoxin is not used to treat Lyme disease.
Antitoxin is a substance that neutralizes the effects of a toxin, such as botulism or tetanus. Lyme disease is caused by a bacterium called Borrelia burgdorferi, which can be treated with antibiotics.
Choice C is wrong because Lyme disease is not transmitted by sharing personal belongings. Lyme disease is spread to humans by the bite of infected ticks that carry the
bacterium. The risk of getting Lyme disease can be reduced by avoiding tick-infested areas, wearing protective clothing, using insect repellent, and removing ticks promptly.
Choice D is wrong because skin necrosis is not a common complication of Lyme disease.
Skin necrosis is the death of skin tissue due to lack of blood supply or infection. Lyme disease can cause a characteristic skin rash called erythema migrans, which is usually circular or oval and expands over time. Other possible signs and symptoms of Lyme disease include fever, headache, fatigue, joint pain, and neurological problems.
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.
