If a suicidal client begins to bang her head against the wall after administration of lorazepam, what should the nurse do next?

In a situation where a suicidal client exhibits self-harm behaviors, such as banging her head against the wall, the priority is to ensure the safety and well-being of the client. Placing the client in leather restraints is a response aimed directly at preventing further harm that the client may inflict on herself. This intervention is necessary when a client's behavior poses an immediate risk to her physical safety and cannot be managed by less restrictive means.

Using restraints should always be considered a last resort after other interventions have been attempted. However, in this specific scenario where the client’s actions indicate a high risk of serious injury, the immediate action to ensure safety is crucial. In conjunction with this measure, it is also important for healthcare professionals to engage in ongoing evaluation and monitoring of the client’s condition and to re-evaluate the need for restraints frequently.

Other options may not adequately address the client's immediate needs. Simply telling the client to stop doesn't provide the necessary intervention for self-harm. Calling for additional medication may delay urgent action needed to contain the situation. Instructing another staff member to sit with the client, while supportive, does not directly prevent the client from harming herself and is therefore not the most effective immediate response.
