What action can provide benefits such as relaxation and increased interaction with patients?

The action that can provide benefits such as relaxation and increased interaction with patients is backrubs. This practice is known for its therapeutic effects, as it promotes physical comfort and emotional well-being. Backrubs can ease muscle tension, reduce stress, and create a calming atmosphere, allowing for a stronger connection between the patient and the caregiver. Engaging in such a comforting activity can lead to improved communication and trust, making patients feel valued and cared for.

In contrast, the other options do not provide the same therapeutic benefits. Alcohol and drugs can adversely affect a patient's health and wellbeing, leading to potential risks and complications. While extra snacks may offer some comfort, they do not provide the same level of relaxation or foster the intimate interactions that backrubs can facilitate.
