Texas Certified Nursing Assistant (CNA) Practice Exam

The technique of keeping the back straight and bending the knees is essential for safe patient lifting. This method helps to distribute the weight more evenly and reduces the risk of injury to the caregiver's back. By bending the knees, the CNA engages their leg muscles, which are stronger than the back muscles, providing a more powerful and safe lifting motion. This alignment ensures that the spine remains in a neutral position during the lift, minimizing strain and potential damage to the back.

Using only the arms for lifting can lead to overexertion and increase the risk of injury, as the back is still required to support the weight. Twisting the body while lifting is unsafe, as it puts undue stress on the spine, increasing the likelihood of injury. Lifting quickly may seem efficient, but it can lead to improper form and greater risk of muscle strain or other injuries. Therefore, maintaining a proper lifting posture is crucial for both the safety of the CNA and the patient.
