Instructions: Choose the best answer for each question. Questions are based on
content from Week 3 readings and accompanying study materials.
1. A nurse is teaching a client about a new prescription of topical beta-
blockers for open-angle glaucoma. The nurse explains that these medications
work by which of the following mechanisms?
A. Increasing the outflow of aqueous humor
B. Decreasing the production of aqueous humor
C. Dilating the corneal pores
D. Lubricating the surface of the eye
The Correct Answer Is B. According to the study guide, topical beta-blockers
like Timolol treat open-angle glaucoma by lowering intraocular pressure (IOP).
They achieve this specifically by decreasing the production of aqueous humor,
which can slow or even stop the progression of the disease.

2. A client has been prescribed Betaxolol for the treatment of glaucoma. The
nurse understands that this specific beta-blocker was chosen for which of the
following reasons?
A. It is the most potent beta-blocker available.
B. It is the only beta-blocker that can be taken orally.
C. It is a beta-1 selective blocker, making it safer for clients with asthma.
Ascorers
,D. It has fewer local adverse effects like stinging and blurred vision.
The Correct Answer Is C. The study guide specifies that for a client with
glaucoma who also has asthma or COPD, Betaxolol is the treatment of choice. This
is because Betaxolol is a beta-1 selective blocker, which means it has a lower risk
of causing bronchospasms compared to non-selective beta-blockers.
...
3. A nurse is monitoring a client who has just started taking topical Timolol
for glaucoma. Which of the following adverse reactions is the client most at
risk for experiencing?
A. Tachycardia and hypertension
B. Blurred vision and bradycardia
C. Diarrhea and abdominal cramping
D. Ringing in the ears (tinnitus)
The Correct Answer Is B. The study guide lists the adverse reactions of beta-
blocker use for glaucoma. These include local effects such as blurred vision, as
well as systemic effects like bradycardia and AV heart block, which is why the
client's pulse should be monitored.
...
4. A client with glaucoma and a history of heart failure is prescribed a topical
beta-blocker. Which of the following nursing actions is most important to
include in the plan of care?
A. Monitoring the client for bronchospasms
B. Monitoring the client's pulse rate
C. Ensuring the client takes the medication with food
D. Instructing the client to avoid all physical activity
Ascorers
, The Correct Answer Is B. The study guide states that when using beta-blockers
for glaucoma, bradycardia and AV heart block can occur, so the pulse should be
monitored. This is especially important in a client with a history of heart failure to
prevent further cardiac decompensation.
...
5. A client with open-angle glaucoma and a history of severe COPD has a new
prescription for eye drops. Which of the following medications would the
nurse expect the provider to order?
A. Carteolol
B. Levobunolol
C. Timolol
D. Betaxolol
The Correct Answer Is D. The study guide explicitly states that for treating
someone with glaucoma and either asthma or COPD, the provider should use only
Betaxolol. This is because it is a beta-1 selective blocker, which minimizes the risk
of bronchospasms that could worsen the client's COPD.
...
6. A nurse is providing discharge teaching to a client with a new prescription
for Timolol eye drops. Which of the following statements by the client
indicates a need for further teaching?
A. "I will apply pressure to the corner of my eye after putting in the drops."
B. "I should expect some local stinging and blurred vision when I first use the
drops."
C. "I need to monitor my pulse regularly while on this medication."
D. "This medication will cure my glaucoma by increasing the fluid in my eye."
