Choice A reason: This is incorrect. With aging, the trunk actually shortens due to intervertebral disc compression, vertebral changes such as kyphosis, and loss of muscle tone. The upper extremities may appear relatively longer, but there is no true increase in trunk length. Degenerative changes in the spine contribute to a stooped posture, not elongation. Choice B reason: This is correct. A backward tipping of the head is a common postural change in older adults. It often compensates for thoracic kyphosis, allowing the individual to maintain horizontal gaze. This adaptation is due to musculoskeletal changes such as weakened neck extensors and altered spinal curvature, particularly increased thoracic flexion. Choice C reason: This is incorrect. Range of motion typically decreases with age due to joint stiffness, cartilage degeneration, and reduced elasticity of connective tissues. Elderly individuals often experience limitations in mobility, especially in weight-bearing joints like hips and knees. Choice D reason: This is incorrect. Bony prominences become more visible in older adults due to loss of subcutaneous fat and muscle mass. Areas such as the elbows, knees, and spine may appear more pronounced, increasing the risk for pressure injuries.
