Prior to administering a beta blocker to a client with glaucoma, the nurse should assess for which coexisting health problem that would place the client at increased risk of adverse events?
 
  1. Type 2 diabetes mellitus
  2. Sleep apnea
  3. Cardiovascular disorders
  4. Rheumatoid arthritis

Question 2

A client with glaucoma is prescribed latanoprost (Xalatan). The nurse instructs the client that this medication, a prostaglandin analog, is used for glaucoma because it:
 
  1. is thought to protect neurons from injury.
  2. enhances the outflow of aqueous humor.
  3. decreases the production of aqueous humor by the ciliary body.
  4. has a relatively short duration of action, and adverse effects can be limited.

Answer to Question 1

Correct Answer: 3
Rationale 1: A client with diabetes would not be adversely affected if prescribed a beta blocker for treatment of glaucoma.
Rationale 2: A client with sleep apnea would not necessarily be adversely affected by beta blockers.
Rationale 3: Beta blockers used to treat glaucoma are minimally absorbed but could cause adverse cardiovascular events such as bradycardia or heart failure and asthma if the beta blocker is not cardioselective.
Rationale 4: Beta blockers would not adversely affect clients with rheumatoid arthritis.
Global Rationale: Beta blockers used to treat glaucoma are minimally absorbed but could cause adverse cardiovascular events such as bradycardia or heart failure and asthma if the beta blocker is not cardioselective. Clients with diabetes, sleep apnea or rheumatoid arthritis will not necessarily be adversely affected by these beta blockers.

Answer to Question 2

Correct Answer: 2
Rationale 1: This medication does not protect neurons from injury.
Rationale 2: Prostaglandin analogs are used to treat open-angle glaucoma because they assist the flow of aqueous humor.
Rationale 3: This medication does not decrease the production of aqueous humor by the ciliary body.
Rationale 4: This medication does not have a short duration of action and limited adverse effects.
Global Rationale: Prostaglandin analogs are used to treat open-angle glaucoma because they assist the flow of aqueous humor. This medication does not protect neurons from injury and does not decrease production of aqueous humor by the ciliary body. It does not have a short duration of action or limited adverse effects.
