How did the PCA demonstrate self-starting behavior in the ED?

The correct choice highlights the PCA's proactive approach in the Emergency Department (ED) by taking the initiative to observe and assist. This behavior illustrates self-starting because it reflects the PCA's drive to engage in their work, anticipate needs, and contribute positively to the patient care environment without waiting for specific instructions or assignments.

In a fast-paced setting like the ED, being able to seamlessly integrate into the workflow and offer help where it's needed is crucial for delivering efficient care. By observing and assisting, the PCA demonstrates awareness of the dynamics of the department and a willingness to support the healthcare team and patients in a meaningful way.

On the other hand, conducting inventory checks, reporting to the charge nurse, and managing paperwork are important tasks but may not necessarily indicate self-starting behavior. These actions might be part of an assigned duty or routine responsibilities that do not require the same level of initiative that observing and assisting does. Thus, the best representation of self-starting behavior in this context is taking the initiative to engage actively with the team and the patients.
