The most common component of renal calculi is:

A. Adjusting thirst sensation is not the primary focus of treatment for Diabetes Insipidus. The condition is more concerned with fluid balance and preventing dehydration due to excessive urination.

B. Hydration is crucial in the management of Diabetes Insipidus, as patients experience excessive urination and fluid loss. Proper hydration helps prevent dehydration and its associated complications.

C. A 24-hour urine collection is used to assess the extent of polyuria but is not a primary treatment strategy. Treatment focuses on managing fluid balance rather than just monitoring urine output.

D. While increasing Antidiuretic Hormone (ADH) or using synthetic ADH (desmopressin) can be part of treatment, the key treatment focus is maintaining adequate hydration to counteract the effects of polyuria.

A. Meconium ileus is a common early sign of cystic fibrosis in newborns. It occurs when the meconium, which is the first stool of a newborn, becomes thick and sticky, leading to a blockage in the intestines. This is often one of the first signs of cystic fibrosis in infants.

B. Cyanosis, while indicative of oxygenation problems, is not a specific sign of cystic fibrosis in newborns. It may be seen in many respiratory or cardiac conditions.

C. Yellow, seedy, loose stools are more commonly associated with normal newborn digestion or conditions like lactose intolerance or gastrointestinal infections, not specifically cystic fibrosis.

D. Coughing is a symptom of cystic fibrosis, but it typically develops later as the disease progresses and affects the lungs, rather than being an early sign in newborns.
