When teaching a client about glaucoma, the nurse explains that both open-angle and closed-angle glaucoma can result in blindness because:
 
  1. pressure is applied to the optic chiasm.
  2. the retina hemorrhages.
  3. the optic nerve is irreversibly damaged.
  4. the retina detaches.

Question 2

The nurse explains to a client with open-angle glaucoma that the purpose of using betaxolol (Betoptic), a selective beta-adrenergic blocker, is to:
 
  1. decrease the production of aqueous humor.
  2. promote the flow of aqueous humor.
  3. reduce the redness and irritation associated with glaucoma.
  4. protect the optic nerve from the increased blood supply that could occur.

Answer to Question 1

Correct Answer: 3
Rationale 1: Glaucoma is not characterized by pressure to the optic chiasm.
Rationale 2: Retinal hemorrhage does not occur with glaucoma.
Rationale 3: The persistence of increased intraocular pressure damages the optic nerve.
Rationale 4: Retinal detachment does not occur with glaucoma.
Global Rationale: The persistence of increased intraocular pressure damages the optic nerve. There is no pressure on the optic chiasm and retinal hemorrhage or detachment does not occur.

Answer to Question 2

Correct Answer: 1
Rationale 1: Beta blockers decrease the production of aqueous humor.
Rationale 2: Beta blockers do not promote the flow of aqueous humor.
Rationale 3: Beta blockers are not given to clients with open-angle glaucoma to reduce redness and irritation.
Rationale 4: Beta blockers are not given to those with glaucoma to protect the optic nerve from an increased blood supply.
Global Rationale: Beta blockers decrease the production of aqueous humor. They do not promote the flow of aqueous humor. They are not given to reduce redness and irritation or to protect the optic nerve from an increased blood supply.
