Answer to Question 1

ANS: C
Neomycin is an ammonia-detoxifying drug because it kills ammonia-producing bacteria in the GI tract. For this reason, it can also be used to decrease the bacterial count in the GI tract before bowel surgery.

Answer to Question 2

ANS: D
Lactulose reduces blood ammonia levels in patients, which leads to improved mental status.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
