A nurse is reinforcing teaching with a parent of a 4-month-old infant during a home visit.

Which of the following statements by the parent indicates an understanding of the teaching?

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.

The correct answer is choice B. Using an electronic messaging system to remind clients when to take medications. Tertiary prevention in healthcare involves measures taken to reduce the impact of an ongoing illness or injury that has lasting effects. This is done by helping people manage long-term, often-complex health problems and injuries in order to improve as much as possible their ability to function, their quality of life, and their life expectancy. In the context of an HIV clinic, reminding clients to take their medications can help manage the disease effectively and prevent complications.

Choice A rationale:

Educating clients about contraindications to specific immunizations is incorrect because this is more aligned with primary prevention, which aims to prevent the onset of an illness or injury before the disease process begins.

Choice C rationale:

Providing clients with information about the benefits of exercise is incorrect as this is generally considered a part of primary prevention, promoting general health to prevent various diseases.

Choice D rationale:

Helping clients understand health screenings covered by their insurance plans is incorrect because this is typically associated with secondary prevention, which involves screening to identify diseases in the earliest stages.
