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
None
None
The Correct Answer is C
A. This is incorrect since the load should be held as close to the nurse's center of gravity (the pelvis) as possible.
B. This is incorrect since the back should remain straight or in its natural "S" curve throughout the lift. The power for the lift should come from the gluteal and femoral muscles, not the back.
C. This is correct since the nurse is squatting and bending at the knees, keeping the back straight. Bending at the knees and hips to engage stronger leg muscles rather than the lower back. The object should also be kept close to the torso, not held at arm’s length, shoulders aligned, no twisting of the trunk, and the eyes forward, head aligned with the spine.
D. This is incorrect since the feet placement should be a wide base of support, one foot slightly ahead of the other. The back alignment includes the spine kept straight, no twisting or bending at the waist. Knees should be bent to lower the body, rather than bending forward.

Correct Answer is C
Explanation
A. Grilled hot dog with French fries: Hot dogs may contain fillers with gluten, and cross-contamination in fries is common if shared fryers are used, making this choice unsafe.
B. Oatmeal cookie with raisins: Unless the oats are certified gluten-free, they may be contaminated with gluten during processing, posing a risk for children with celiac disease.
C. Baked sweet potato with cinnamon: Sweet potatoes are naturally gluten-free, and cinnamon is safe as well. This option provides a nutritious and safe food for a child with celiac disease.
D. Hazelnut butter on wheat toast: Wheat toast contains gluten and should be strictly avoided in individuals with celiac disease, even if the topping is gluten-free.
Correct Answer is C
Explanation
A. Systemic lupus erythematosus: SLE primarily affects connective tissue and organs through inflammation but rarely impacts the neuromuscular coordination needed for swallowing. It does not significantly raise aspiration risk during enteral feeding.
B. Increased gastric motility: Increased gastric motility helps clear stomach contents more quickly, decreasing the chance of regurgitation and aspiration. It is not typically considered a risk factor for aspiration.
C. Parkinson's disease: Parkinson’s disease impairs muscle coordination, including muscles used for swallowing. This dysphagia increases the risk of aspiration, especially with liquid feedings via a nasogastric tube.
D. Celiac disease: Celiac disease affects the small intestine’s ability to absorb nutrients but does not interfere with the swallowing reflex. It does not increase the risk of aspiration with tube feedings.
