Answer to Question 1

Correct Answer: 4
Rationale 1: Beta blockers are used to treat hypertension and would not be contraindicated for this reason.
Rationale 2: A deep-vein thrombosis would not be a concern when administering timolol.
Rationale 3: Beta blockers can be used to reduce the heart rate. This history would not be a concern when administering timolol.
Rationale 4: Nonselective beta blockers can cause bronchospasm. Clients with asthma are at risk for this adverse effect.
Global Rationale: Nonselective beta blockers can cause bronchospasm. Clients with asthma are at risk for this adverse effect. Beta blockers are used to treat hypertension and would not be contraindicated for this reason. A deep-vein thrombosis would not be a concern when administering timolol. Beta blockers can be used to reduce the heart rate. This history would not be a concern when administering timolol.

Answer to Question 2

Correct Answer: 4
Rationale 1: Acute eye pain is seen with closed-angle glaucoma.
Rationale 2: Floaters are not a major symptom of either type of glaucoma.
Rationale 3: A bulging iris is a manifestation of acute obstruction that is more likely seen with closed-angle glaucoma.
Rationale 4: Both open-angle and closed-angle glaucoma are the result of an accumulation of aqueous humor in the anterior cavity.
Global Rationale: Both open-angle and closed-angle glaucoma are the result of an accumulation of aqueous humor in the anterior cavity. Acute eye pain is seen with closed-angle glaucoma. Floaters are not a major symptom of either type of glaucoma. A bulging iris is a manifestation of acute obstruction that is more likely seen with closed-angle glaucoma.
