RH has a history of COPD. The CNA checks his vital signs at the beginning of the shift and tells you that his pulse ox reading is 91%. What should the nurse advise the CAN does next:

An Incentive Spirometer is a device that helps patients take deep breaths and improve their lung function. It encourages patients to take deep breaths and to hold them for a few seconds. The device also helps to monitor and measure lung volume. By using an incentive spirometer, MA can expand her lung volume as much as possible and allow for proper oxygen blood exchange within the alveoli. This is an important technique to help prevent pneumonia and other respiratory complications.

The other options mentioned, 4L of oxygen via Nasal Cannula, Fluter Valve, and Abdominal Binder, are not appropriate devices to help MA achieve proper breathing techniques and expand lung volume. 4L of oxygen via Nasal Cannula is used to provide supplemental oxygen to patients who have difficulty breathing. Fluter Valve is a handheld device used for airway clearance in patients with chronic obstructive pulmonary disease (COPD) or cystic fibrosis. An abdominal binder is a wrap that is placed around the abdomen to support the abdominal muscles and help reduce pain after surgery or injury. These devices do not help improve lung function and are not appropriate for MA's condition.

Stridor is a high-pitched, inspiratory sound that indicates partial obstruction of the upper airway. It is a common finding in newborns and can occur due to the presence of mucus, fluid, or a small airway that has not yet fully developed. It is important to note that while stridor is an expected finding in newborns, it should still be assessed and monitored closely by healthcare professionals.

Bruits are abnormal sounds heard over blood vessels and are not related to breath sounds. Crackles are a series of brief, discontinuous, nonmusical sounds heard during inspiration or expiration, indicating fluid in the lungs. Wheezing is a high-pitched, musical sound heard during expiration and can indicate the narrowing of the airways. These sounds are not typically expected in the breath sounds of a newborn.
