A nurse is admitting an adolescent who has rubella.

Which of the following actions should the nurse take?

The correct answer is choice B. Use an ibuterol inhaler.

Choice A rationale:

Completing oral hygiene is important for overall health, but it is not specifically related to the preparation for postural drainage in cystic fibrosis patients. Postural drainage is a technique used to clear mucus from the lungs, and oral hygiene does not directly affect this process.

Choice B rationale:

Using a bronchodilator, such as an ibuterol inhaler, is recommended before postural drainage because it helps to open the airways, making the drainage process more effective. Bronchodilators are often used to relax the muscles around the airways, which can become constricted in conditions like cystic fibrosis.

Choice C rationale:

Taking pancrelipase is related to aiding digestion in cystic fibrosis patients who have pancreatic insufficiency. While it is an important part of the overall management of cystic fibrosis, it is not directly related to the preparation for postural drainage.

Choice D rationale:

Eating a meal before postural drainage is not recommended because a full stomach can make the process uncomfortable and less effective. It is generally advised to perform postural drainage on an empty stomach to ensure that the mucus can be cleared from the lungs more easily.

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.
