Which of the following is the most common substance found on analysis of a renal stone?
Calcium Oxalate
Potassium phosphate
Magnesium-ammonium phosphate
Uric Acid
The Correct Answer is A
A. Calcium Oxalate
The most common substance found in the analysis of renal stones is calcium oxalate. Calcium oxalate stones are the most prevalent type of kidney stones, accounting for the majority of cases. These stones can form when there is an excess of calcium or oxalate in the urine, and they can vary in size and shape. Other types of kidney stones include uric acid stones, struvite stones (magnesium-ammonium phosphate), and cystine stones, but calcium oxalate stones are the most common.

Correct Answer is A
Explanation
A. Sedentary lifestyle - Lack of weight-bearing exercise and physical activity is a significant risk factor for the development of osteoporosis. Weight-bearing exercises help maintain bone density and strength. Sedentary individuals are more prone to osteoporosis.
B. Long-term use of diuretics - Long-term use of certain medications, such as corticosteroids, can increase the risk of osteoporosis. Diuretics are not typically associated with osteoporosis risk, although some medications can affect bone health.
C. Prolonged stress - Chronic stress can have negative effects on overall health, but it is not a direct risk factor for osteoporosis.
D. Obesity - Obesity is generally considered a protective factor against osteoporosis. Individuals with higher body weight tend to have stronger bones due to the mechanical load placed on the bones, reducing the risk of osteoporosis.
Correct Answer is C
Explanation
A. Malignant hypothermia: This is a rare but life-threatening reaction to certain medications used during anesthesia. It doesn't typically manifest with calf edema.
B. Pulmonary embolism: While pulmonary embolism can occur as a complication in some cases, it is characterized by symptoms like sudden shortness of breath, chest pain, and may not directly cause calf edema.
C. Acute compartment syndrome
Increasing edema in the calf of a client with multiple fractures of the leg is a manifestation of acute compartment syndrome. Acute compartment syndrome occurs when there is increased pressure within a muscle compartment, which can lead to reduced blood flow, nerve damage, and tissue hypoxia. The edema and increased pressure can compress blood vessels, nerves, and muscle tissue within the compartment, resulting in symptoms such as severe pain, edema, and potential vascular compromise.
D. Fat embolism syndrome: This syndrome can occur in clients with long bone fractures, but it is characterized by respiratory and neurologic symptoms, not isolated calf edema.
