Answer to Question 1

B
The pressure of the pleural space has less than the pressure of outside air, which prevents the lungs from collapsing on exhalation.

Answer to Question 2

A
Feedback:
The client likely did not clean the lenses properly. This likely caused both an infection and an abrasion in the eye. People who are not conscientious about following a routine for contact lens care are at a risk for infection, eye abrasion, and permanent damage to the cornea. New, rigid, and colored contact lenses are not causes of eye infection. Any type of lenses should be cleaned properly and thoroughly.
