A nurse is caring for a child who has cystic fibrosis and requires postural drainage.
Which of the following actions should the nurse take?
Hold hand flat to perform percussions on the child.
Perform the procedure twice each d
Perform the procedure prior to meals.
Administer a bronchodilator after the procedure
The Correct Answer is C
The correct answer is choice C. Perform the procedure prior to meals.
This is because postural drainage involves positioning the child in different ways to help drain the mucus from the lungs.
If the child has a full stomach, this can cause nausea, vomiting, or aspiration. Therefore, the nurse should perform the procedure before meals or at least 1 hour after meals.
Choice A is wrong because the nurse should not hold the hand flat to perform percussions on the child.
Percussions are rhythmic clapping on the chest wall to loosen the mucus. The nurse should use a cupped hand to create a small air pocket that enhances the vibrations and prevents bruising.
Choice B is wrong because the nurse should not perform the procedure twice a day. The recommended frequency of postural drainage is 3 to 4 times a day, or more if needed, depending on the child’s condition and tolerance.
Choice D is wrong because the nurse should not administer a bronchodilator after the procedure.
A bronchodilator is a medication that relaxes and widens the airways, making it easier to breathe. The nurse should administer a bronchodilator before the procedure to enhance the effectiveness of postural drainage.

Correct Answer is C
Explanation
The correct answer is choice C. “Perform chest percussion and postural drainage at least twice daily.” This is because chest percussion and postural drainage are airway clearance techniques that help remove thick mucus from the lungs of children who have cystic fibrosis. This can prevent respiratory infections and improve lung function.
Choice A is wrong because a bronchodilator should be administered before airway clearance therapy, not after. A bronchodilator helps open up the airways and make it easier to cough up mucus.
Choice B is wrong because pancreatic enzymes should be administered with meals and snacks, not on an empty stomach.
Pancreatic enzymes help digest fats, proteins, and carbohydrates in children who have cystic fibrosis. This can prevent malnutrition and growth failure.
Choice D is wrong because there is no need to restrict gluten intake for children who have cystic fibrosis, unless they also have celiac disease.
Gluten is a protein found in wheat, barley, and rye that can cause intestinal damage in people who have celiac disease. Cystic fibrosis does not affect the ability to tolerate gluten.
Correct Answer is C
Explanation
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.
