Final answer:
A nurse should explain to the family member that a Posey vest restraint was applied because the client's actions placed them at high risk for self-harm, and it is part of an individualized care plan to ensure their safety.
Step-by-step explanation:
The appropriate response to the family member's question about the use of a Posey vest restraint (safety reminder device) is to explain that the client's actions place them at high risk for self-harm. Restraints such as the Posey vest are typically used in healthcare settings to prevent patients from injuring themselves or others, especially when they are prone to falls, wandering, or removing life-sustaining medical devices.
It is important to communicate that the decision to apply the restraint was made based on a thorough assessment by the healthcare provider and is part of the client's individualized care plan. Use of a restraint is often a last resort, after other measures to ensure safety are considered, such as increased supervision or the use of less restrictive interventions. The healthcare team's goal is to protect the client's physical safety while respecting their dignity and rights.
