Answer to Question 1

C
Psychogenic diabetes insipidus (DI) is a rare form of the disease that occurs with compulsive drinking of more than 5 L of water a day. Long-standing psychogenic DI closely mimics nephrogenic DI because the kidney tubules become less responsive to antidiuretic hormone as a result of prolonged conditioning to hypotonic urine.

Answer to Question 2

A
Thoracotomy may be necessary for patients who require persistent blood transfusions or who have significant bleeding (200 mL/hr for 2 to 4 hours or more than 1500 mL on initial tube insertion) or when there are injuries to major cardiovascular structures.
