A 70 year old female presents with a hip fracture secondary to osteoporosis. This condition is caused by an increase in bone:
density
formation
resorption
mineralization
The Correct Answer is C
A. Density: Osteoporosis is characterized by decreased bone density rather than an increase. Loss of bone mass makes bones more fragile and susceptible to fractures. Increased density would be protective against fractures.
B. Formation: Bone formation by osteoblasts is reduced or outpaced in osteoporosis. The imbalance favors bone loss rather than new bone production. Increased formation would strengthen bone, not weaken it.
C. Resorption: Osteoporosis results from increased bone resorption by osteoclasts relative to bone formation. This imbalance leads to thinning of bone structure and reduced strength. The accelerated breakdown of bone tissue increases fracture risk.
D. Mineralization: Mineralization refers to the deposition of calcium and phosphate in bone matrix. Osteoporosis does not involve increased mineralization; instead, overall bone mass is reduced. Increased mineralization would not explain bone fragility.

Correct Answer is A
Explanation
Diabetes insipidus is characterized by a deficiency of antidiuretic hormone (ADH) or a renal resistance to its effects. In central diabetes insipidus, the posterior pituitary fails to produce sufficient ADH, leading to lower-than-normal blood levels. This results in excessive urine output and risk of dehydration. Low ADH levels reduce water reabsorption in the kidneys, causing dilute urine and increased thirst as the body attempts to maintain fluid balance.
