Which is the least restrictive measure to maintain safety in a confused patient trying to grasp their IV?

Using a safety "mitt" on the patient's right hand is the least restrictive measure for maintaining safety in a confused patient attempting to grasp their IV. This approach minimizes physical restraint while still allowing for some freedom of movement. It specifically restricts the movement of the hand that poses a risk to the IV line while enabling the patient to use their other hand and facilitating easier interaction with staff.

This option is particularly beneficial as it balances the need for safety with the patient's dignity and comfort. A safety mitt can help prevent accidental dislodgment of the IV while not completely immobilizing the patient, which is important for reducing agitation and empowering the patient.

In contrast, full body restraints, while effective in preventing movement, can significantly increase feelings of confinement, distress, and may lead to other complications such as pressure injuries or increased agitation. Soft wrist restraints provide a bit more freedom than full body restraints but still may provoke distress or fear in a confused patient. Verbal redirection, though supportive, may not be sufficient to keep the patient safe from grasping their IV when confusion is prevalent. Thus, the safety mitt option stands out for its balance of safety with a less invasive approach.
