Answer to Question 1

ANS: A
Glaucoma is caused when the intraocular pressure becomes too high and stays high long enough to cause tissue ischemia and death. At that point, vision loss is permanent. Glaucoma does not have to cause blindness. Trauma can cause glaucoma but is not the most common cause. Glaucoma is not an infection.

Answer to Question 2

ANS: D
Clopidogrel is an antiplatelet aggregate and could increase bleeding. The surgeon should be notified immediately. The nurse should find out when the last dose of the drug was, but the priority is to notify the provider. This drug is not monitored with PT and INR. Documentation should occur but is not the priority.
