What action must be taken by the nurse when treating a client with a stab wound?

Notifying the police due to the nature of the injury is essential when treating a client with a stab wound. This action aligns with legal requirements and protocols, particularly in cases involving potential criminal activity or violence. When a patient presents with a stab wound, there is a clear obligation for the healthcare provider to ensure the safety of the individual and the community. Reporting such incidents can help prevent further violence and allow law enforcement to take appropriate action. This step also helps ensure documentation and investigation into the circumstances surrounding the injury, which is critical for both legal and medical records.

Other options, while they may relate to patient care, do not directly address the immediate responsibilities associated with treating injuries from violence or potential crime. Ensuring the involvement of law enforcement allows for comprehensive care that includes addressing the psychosocial aspects of trauma and safety considerations.
