Answer to Question 1

Ans:
B

Feedback:

A unique form of lactic acidosis, called D-lactic acidosis, can occur in persons with intestinal disorders that involve the generation and absorption of D-lactic acid. D-lactic acidosis can occur in persons with jejunoileal bypass, in which there is impaired reabsorption of carbohydrate in the small intestine. Persons with D-lactic acidosis experience episodic periods of metabolic acidosis often brought on by eating a meal high in carbohydrates. Manifestations include confusion, cerebellar ataxia, slurred speech, and loss of memory. They may complain of feeling (or may appear) intoxicated.

Answer to Question 2

Ans:
D

Feedback:

Young women as well as persons with diabetes are at high risk of UTIs. Neither postsurgical recovery nor renal failure is necessarily a direct risk for UTI development, and high urine output would prevent decrease rather than increase in UTI risk.
