Proper body mechanics for lifting a patient include which two of the following options?

Standing with your feet shoulder-width apart is crucial for maintaining proper body mechanics while lifting a patient. This position provides a wider base of support, which enhances stability and balance during the lift. It helps distribute the weight more evenly across your body, reducing the risk of injury to your lower back and other muscles. A stable stance is key when performing any physical task involving lifting or moving a patient to prevent falls and ensure safety.

The other options involve poor body mechanics. Lifting with your back can lead to significant strain and injury, particularly to the lower back. Slightly bending your knees is not adequate support for a strong lift, and twisting at the waist places undue stress on the spine, increasing the risk of injury during the lift. Therefore, option B is the best choice for safe and effective lifting practices in patient care.
