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 C
Explanation
The correct answer is choice C. Administering potassium via IV bolus is an example of malpractice in nursing.
This is because potassium is a medication that can cause cardiac arrest if given too quickly or in high doses. A nurse who administers potassium via IV bolus is not providing the standard of care that a similarly trained nurse would have offered under the same circumstances.
This could result in harm or death to the patient.
Choice A is wrong because placing a yellow bracelet on a client who is at risk for falls is not malpractice, but rather a safety measure.
A yellow bracelet indicates that the client needs assistance with mobility and should not be left alone. This is a common practice in many health care facilities to prevent falls and injuries.
Choice B is wrong because leaving a nasogastric tube clamped after administering oral medication is not malpractice, but rather a mistake.
A nasogastric tube is a tube that goes through the nose and into the stomach to deliver nutrition or medication.
It should be unclamped after giving oral medication to allow the medication to enter the stomach and prevent reflux or aspiration. However, this error does not rise to the level of malpractice unless it causes harm to the patient, such as vomiting, choking, or infection.
Choice D is wrong because documenting communication with a provider in the progress notes of the client’s medical record is not malpractice, but rather a good practice. A nurse
Correct Answer is B
Explanation
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.
