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 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.
