Final answer:
The statement identifying that a client showing agitation is at greater risk for violent behavior is true. Agitated clients may become unpredictable and it is critical for healthcare providers to use de-escalation techniques to ensure safety.
Step-by-step explanation:
The statement 'A client is at the greatest risk for violent behavior as evidenced by the client's agitation' can be considered true. Clients who are displaying signs of agitation may become unpredictable and have an increased risk for violent behavior. This is often due to underlying issues such as mental health disorders, substance abuse, or situational stress.
When a client is agitated, it is crucial for healthcare providers to approach the situation with caution, implementing de-escalation techniques and safety interventions as necessary. However, not all agitated clients will become violent; the risk depends on individual factors and the specific circumstances surrounding the agitation.
