The diagnosis of Cushing syndrome is often based on:
Obesity
A 24-hour urine collection
Chronic renal failure
Alcoholism
The Correct Answer is B
A. Obesity is a common symptom of Cushing syndrome but is not the primary diagnostic criterion. Other tests are needed to confirm the diagnosis.
B. A 24-hour urine collection for cortisol is one of the most common and reliable methods for diagnosing Cushing syndrome. Elevated cortisol levels in the urine are indicative of the syndrome.
C. Chronic renal failure is not related to the diagnosis of Cushing syndrome. While Cushing syndrome may affect renal function, it is not the primary diagnostic tool.
D. Alcoholism can cause symptoms similar to those of Cushing syndrome, but it is not used as a diagnostic criterion. The diagnosis of Cushing syndrome requires specific tests, such as urine cortisol measurement.

Correct Answer is A
Explanation
A. Desmopressin (DDAVP) is the correct treatment for Diabetes insipidus. This medication is a synthetic form of vasopressin, which helps the kidneys to retain water, thereby reducing the symptoms of excessive urination and thirst in individuals with Diabetes insipidus.
B. Furosemide is a loop diuretic used to treat fluid retention, not Diabetes insipidus. It increases urine output, which would worsen the condition in patients with Diabetes insipidus.
C. Diuretics are used to increase urine output and are not used in the treatment of Diabetes insipidus, as they could exacerbate dehydration.
D. Corticosteroids are not used to treat Diabetes insipidus. They are typically used to treat inflammatory conditions, such as rheumatoid arthritis, but not Diabetes insipidus.
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.
