Answer to Question 1

B
In SIADH, the increased levels of circulating ADH are unrelated to the serum sodium concentration. Aldosterone production from the adrenal glands is also suppressed.

Answer to Question 2

B, C, F
Circulating myoglobin can lead to the development of kidney failure by three mechanisms: decreased renal perfusion, cast formation with tubular obstruction, and direct toxic effects of myoglobin in the kidney tubules. Dark teacolored urine suggests myoglobinuria. The most rapid screening test is a serum creatine kinase level. Urine output and serial creatine kinase levels should be monitored. Alkalinization of the urine and administration of diuretics have been studied, but their roles in the prevention or management of rhabdomyolysis are not firmly established.
