Answer to Question 1

ANS: B
The Snellen Eye Chart tests visual acuity. A vision evaluation of 20/40 means that the patient can see at 20 feet what the person with normal vision can see at 200 feet.

Answer to Question 2

ANS: A
The amount of hormone released is controlled by a negative feedback system. When the level of the particular hormone is appropriate, the target organ signals the pituitary to stop the stimulation of the target organ.
