Answer to Question 1

2
Other neurosensory elements located in the retina are cones, which mediate color vision. Rods mediate black-and-white vision. The optic disc and iris are not responsible for color vision.

Answer to Question 2

3
Serevent is a long-acting agent and is not to be used as rescue medication during acute episodes. Albuterol (also sold under the brand names Proventil and Ventolin) is a short-acting agent used as a rescue medication.
