A staff education nurse is evaluating a group of nurses during a new employee orientation on the use of proper body mechanics when lifting. Which of the following images indicates the appropriate use of ergonomic principles?
A.
B.
C.
D.
A
B
C
D
The Correct Answer is A
Using proper body mechanics is vital to prevent injury and ensure safe lifting. Key principles include keeping the back straight and neutral to reduce spinal stress and bending at the knees and hips to engage stronger leg muscles rather than the lower back. Maintaining a shoulder-width stance provides stability, while holding objects close to the body decreases spinal strain. Lifting with the legs, not the back, further protects the spine. Twisting should be avoided—pivoting with the feet maintains alignment and reduces injury risk. Keeping the head and neck aligned with the spine improves posture and visual focus. Using smooth, controlled movements prevents muscle strain and dropped objects. Assessing an object’s weight before lifting helps determine if help or equipment is needed, preventing overexertion. Supportive footwear with a good grip ensures balance and minimizes fall risk. These ergonomic practices promote safety, reduce injuries, and are essential in both clinical and everyday environments.

Correct Answer is D
Explanation
A. Position the client's knee slightly higher than the hips when up in a chair: This position can cause hip flexion greater than 90 degrees, increasing the risk of dislocation. Postoperative clients should keep their hips higher than their knees when sitting.
B. Raise the head of the client's bed to a high-Fowlers position: High-Fowlers positioning creates excessive hip flexion, which places strain on the new prosthesis and increases the likelihood of dislocation following hip replacement surgery.
C. Elevate the client's affected leg on a pillow when in bed: Elevating the leg can be appropriate for reducing swelling, but it does not prevent dislocation. Proper leg alignment is more critical than elevation in this context.
D. Keep an abduction pillow between the client's legs: An abduction pillow maintains the hip in proper alignment by preventing adduction and internal rotation, which are common causes of hip prosthesis dislocation in the early postoperative period.
Correct Answer is C
Explanation
A. “Use an indoor tanning bed instead of outside.”: Indoor tanning exposes the skin to concentrated ultraviolet radiation, which significantly increases the risk of developing skin cancer, including melanoma. It is not a safe alternative to outdoor sun exposure.
B. “Plan to spend time tanning between 10 am and 2 pm.”: This time frame represents peak UV radiation hours, and sun exposure should be minimized during this period to reduce the risk of skin damage and cancer.
C. “Apply sunscreen before and after swimming.”: Sunscreen should be applied 15–30 minutes before sun exposure and reapplied after swimming or sweating. Water can wash off sunblock, so reapplication helps maintain effective protection against UV rays.
D. “Use sunblock with an SPF of 10 when I am outdoors.”: An SPF of 10 provides minimal protection and is inadequate for preventing skin damage. A minimum SPF of 30 is recommended for effective protection against both UVA and UVB radiation.
