When caring for a client who has a new prescription for wrist restraints, which action is necessary for the nurse?

Padding the client's wrist before applying the restraints is a crucial step in ensuring the client's comfort and preventing injury. Restraints can cause skin breakdown, pressure injuries, or other complications if they are too tight or applied directly onto the skin. By padding the wrists, the nurse helps to distribute pressure more evenly and protects the skin from abrasion, which is essential for maintaining the dignity and safety of the client.

The context provided by the other options highlights common practices related to the use of restraints, but they do not primarily address the immediate need for safety and comfort that padding provides. Evaluating circulation every 8 hours could lead to potential delays in identifying circulation issues, as assessments should typically occur more frequently. Removing restraints every 4 hours is important for evaluating the client's status, but the necessity of ensuring comfort during the initial application and preventing harm takes priority. Securing restraint ties to the bed's side rails is a standard procedure, but it does not contribute to the immediate safety and comfort of the client's wrists. Therefore, padding the wrists is the most critical action to take when using wrist restraints for the first time.
