What method of observation should a CNA use when witnessing a resident coughing and wheezing?

The correct answer, which focuses on hearing, reflects the importance of auditory observation in a clinical setting. When a resident is coughing and wheezing, these sounds can provide crucial information about their respiratory condition. By actively listening, a CNA can assess the severity of the wheezing, which may indicate an underlying issue such as asthma, an allergic reaction, or another respiratory concern.

Vigilant auditory observation helps the CNA determine whether the resident is experiencing difficulty breathing, which necessitates prompt action or reporting to a nurse or other healthcare professional. This aspect of observation is critical in maintaining the health and safety of residents, allowing for timely interventions when respiratory distress is noticeable.
