The most common component of renal calculi is:
Cystine
Uric acid
Calcium oxalate
Struvite
The Correct Answer is C
A. Cystine stones are rare and occur due to a genetic disorder called cystinuria. They are not the most common type of renal calculi.
B. Uric acid stones are also relatively common, especially in individuals with gout or those with high levels of uric acid in the urine. However, calcium oxalate is more common.
C. Calcium oxalate is the most common type of renal calculi, accounting for about 70-80% of kidney stones. These stones form when calcium combines with oxalate in the urine.
D. Struvite stones are associated with urinary tract infections caused by urease-producing bacteria. They are less common than calcium oxalate stones.

Correct Answer is A
Explanation
A. Dehydration is a major risk factor for renal calculi (kidney stones). When there is insufficient fluid intake, urine becomes concentrated, allowing substances like calcium, oxalate, and uric acid to crystallize and form stones.
B. A sedentary lifestyle can contribute to weight gain and other health issues, but it is not directly linked to the formation of kidney stones.
C. Drinking 32 ounces of milk per day is not a significant risk factor for kidney stones. In fact, moderate calcium intake from food can help prevent certain types of stones. Excessive calcium intake from supplements, however, can increase the risk.
D. Running 5 miles does not directly increase the risk of kidney stones. Regular physical activity, in general, helps promote overall health and hydration, which can reduce the risk of stone formation.
Correct Answer is A
Explanation
A. The absence of chronic disease is not a strict requirement for effective perfusion. While chronic diseases can impact perfusion, such as through the effects of diabetes or hypertension on the cardiovascular system, effective perfusion can still occur in individuals with chronic conditions if other factors are managed appropriately.
B. Adequate blood volume is essential for effective perfusion because without enough blood, oxygen and nutrients cannot be delivered to tissues.
C. An open airway is crucial for effective perfusion because it allows for proper oxygenation, which is necessary for the delivery of oxygen to tissues via the bloodstream.
D. Functional systemic circulation is required for effective perfusion, as it ensures that blood can flow throughout the body to deliver oxygen and nutrients to tissues and remove waste products.
