How can CNAs recognize changes in a patient’s condition?

Recognizing changes in a patient’s condition is primarily achieved through direct observation of physical signs and symptoms. This method allows CNAs to monitor and assess the patient’s health on a continuous basis. For instance, changes in vital signs like temperature, pulse, or respiration rates, as well as observable signs such as changes in skin color, mobility, or behavior, provide essential information about the patient's status. By being attentive to these changes, CNAs play a critical role in identifying when a patient may require further medical evaluation or intervention.

In contrast, while reading patient history documents can provide background information, it does not allow for real-time assessment of the current condition. Relying solely on a doctor's observations ignores the importance of the CNA's own assessments, which are vital for continuous care. Conducting formal patient interviews, although useful, may not always capture immediate changes that are observable and can reflect the patient’s current state more effectively. Therefore, direct observation is the most effective way for CNAs to recognize and respond to changes in a patient’s condition.
