An elderly female patient is admitted to the hospital with a fractured hip. Which statement best describes the relationship between osteoporosis and the occurrence of pathological fractures related to aging?
There is an imbalance between formation of new bone and the resorption of existing bone.
An Invasion of a pathogen leads to infection: causing destruction and weakening of the bone.
A decrease in blood supply to the bone results in bony necrosis or the death of bone cells.
Increased amounts of estrogen in postmenopausal women contribute to bone loss.
The Correct Answer is A
A. There is an imbalance between the formation of new bone and the resorption of existing bone: Osteoporosis occurs when bone resorption outpaces bone formation, leading to decreased bone density and increased susceptibility to fractures.
B. An invasion of a pathogen leads to infection, causing destruction and weakening of the bone: This describes osteomyelitis, a bone infection, not osteoporosis.
C. A decrease in blood supply to the bone results in bony necrosis or the death of bone cells: This describes avascular necrosis, not osteoporosis.
D. Increased amounts of estrogen in postmenopausal women contribute to bone loss: In fact, decreased estrogen levels after menopause contribute to bone loss and osteoporosis.

Correct Answer is B
Explanation
A. Elevating the head of the bed promotes venous return and helps increase the ICP: This is incorrect. Elevation of the head of the bed helps to decrease intracranial pressure (ICP) by promoting venous drainage rather than increasing it.
B. Elevation of the head of the bed aids in maintaining cerebral perfusion: Elevating the head of the bed helps to decrease ICP, which in turn aids in maintaining adequate cerebral perfusion pressure.
C. Elevation of the head of the bed will increase intracranial pressure (ICP): This is incorrect. Elevation of the head of the bed is intended to reduce ICP, not increase it.
D. The nurse should keep the head of the bed flat to ensure adequate arterial circulation: This is incorrect. Keeping the head of the bed flat can increase ICP, which is counterproductive in managing intracranial pressure.
