Question

A client is prescribed timolol ophthalmic drops to decrease the intraocular eye pressure associated with glaucoma. Which comorbidity should the nurse notify the health care provider about? Select all that apply.

Answers

  1. Cataracts
    • Rationale:

      This answer is not correct because cataracts and the treatment of cataracts is not a condition severely affected by the use of timolol ophthalmic solution. Timolol, if absorbed systemically, can have a negative impact on comorbidities of asthma, severe COPD, severe heart failure, bradycardia, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

  2. Diabetes
    • Rationale:

      This answer is not correct because diabetes is not a condition severely affected by the use of timolol ophthalmic solution. Timolol, if absorbed systemically, can have a negative impact on comorbidities of asthma, severe COPD, severe heart failure, bradycardia, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

  3. Asthma
    • Rationale:

      This answer is correct because timolol ophthalmic solution is a beta blocker and, if absorbed systemically, can cause further narrowing of bronchioles of a person with asthma. Other conditions negatively impacted by the use of this solution are severe COPD, severe heart failure, bradycardia, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

  4. Heart failure
    • Rationale:

      This answer is correct because timolol ophthalmic solution is a beta blocker and, if absorbed systemically, can cause worsen heart failure and cause an unsafe drop of the heart rate and blood pressure when combined with medications often used to treat heart failure (e.g., digoxin). Other conditions negatively impacted by the use of this solution are severe COPD, asthma, bradycardia, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

  5. Bradycardia
    • Rationale:

      This answer is correct because timolol ophthalmic solution is a beta blocker and, if absorbed systemically, can cause worsen bradycardia. Other conditions negatively impacted by the use of this solution are severe COPD, asthma, severe heart failure, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

Overview

Timolol ophthalmic solution is used as a beta-blocker to lower intraocular pressure in the eyes of the person with glaucoma.. These eye drops can enter the bloodstream and have systemic actions on the body.

Explanation

Learning Outcomes

Timolol ophthalmic drops are utilized to decrease the elevated intraocular eye pressure of a person with glaucoma. can easily enter the bloodstream and impose a systemic effect on the body. When beta blocker medications enter the body systemically, they lower the heart rate, blood pressure, and can narrow the bronchioles. This can cause a negative outcome if a client has asthma, severe COPD, severe heart failure, bradycardia, and other serious heart conditions (e.g., 2nd and 3rd degree heart block).

Test Taking Tip

The suffix, “-olol” is often associated with beta blockers. Remember, beta blockers will block the sympathetic nervous system effects on the body and cause a decreased heart rate, blood pressure, and bronchoconstriction.
