A patient is undergoing oxygen therapy through a nasal cannula.If the patient inquires about the reason for having oxygen tubing in their nose, what explanation about the cannula should the nurse provide?

Choice A rationale
The prone position, which involves lying flat on the stomach, is not typically recommended for a child with respiratory failure due to pneumonia. While prone positioning can be beneficial in

certain cases of severe acute respiratory distress syndrome, it does not generally allow for maximal lung expansion.
Choice B rationale
The supine position, which involves lying flat on the back, is not typically recommended for a child with respiratory failure due to pneumonia. This position can make it more difficult for the lungs to expand fully, potentially worsening respiratory distress.
Choice C rationale
The side-lying position is not typically recommended for a child with respiratory failure due to pneumonia. While this position can be comfortable for resting, it does not generally allow for maximal lung expansion.
Choice D rationale
The upright position is typically recommended for a child with respiratory failure due to pneumonia. Sitting upright can help to maximize lung expansion and improve oxygenation.

Choice A rationale
Vibration is a technique used in chest physiotherapy to increase the turbulence of the client’s exhaled air. It involves the use of manual or mechanical techniques to create vibrations in the chest wall during exhalation. This helps to loosen mucus in the airways and improve clearance of secretions.
Choice B rationale
Percussion, also known as chest clapping, is a technique used in chest physiotherapy to help loosen and mobilize secretions in the lungs. However, it does not specifically increase the turbulence of exhaled air.
Choice C rationale
Postural drainage involves positioning the client in specific ways to use gravity to assist in the removal of secretions from the lungs. While it can be beneficial in managing respiratory infections, it does not directly increase the turbulence of exhaled air.
Choice D rationale

Nebulization involves the use of a machine to create a mist of medication that the client inhales into the lungs. While it can be used to deliver medications to help manage respiratory infections, it does not increase the turbulence of exhaled air.
