MULTIPLE CHOICE
| a. | Asthma |
| b. | Atrioventricular heart block |
| c. | Pulmonary hypertension |
| d. | Sinus bradycardia |
ANS: A
Timolol is a beta blocker and can precipitate bronchoconstriction when absorbed systemically. Patients with asthma will develop shortness of breath and wheezing. These symptoms are not associated with AV block, pulmonary hypertension, or sinus bradycardia.

| a. | “Angle-closure glaucoma may be asymptomatic until irreversible damage has occurred.” |
| b. | “Both types are more common in African American patients.” |
| c. | “Drug therapy is the definitive treatment for angle-closure glaucoma.” |
| d. | “Early treatment with prostaglandin analogs can stop the progression of POAG.” |
ANS: D
Prostaglandin analogs are first-line agents for treating POAG, and early treatment can stop the progression. Angle-closure glaucoma has a rapid onset of painful symptoms. POAG is more common in African Americans but angle-closure glaucoma is not. Surgery, not drugs, is the definitive treatment for angle-closure glaucoma.

| a. | Monitor the patient’s heart rate, respiratory rate, and blood pressure. |
| b. | Notify the provider that the patient shows signs of angle-closure glaucoma. |
| c. | Reassure the patient that these are localized, reversible effects of the drug. |
| d. | Request an order for an antihistamine to treat this allergic response to the drug. |
ANS: C
Local effects of timolol and other beta blockers are generally minimal, but transient ocular stinging can occur. There is no need to monitor vital signs, because this does not represent a systemic reaction. This is not a sign of angle-closure glaucoma. Antihistamines will not help.

| b. | Report this toxic effect to the patient’s provider. |
| c. | Tell the patient that this indicates an increased risk of migraine headaches. |
| d. | Tell the patient that this effect will reverse when the medication is withdrawn. |
ANS: A
Latanoprost can cause a harmless, heightened brown pigment of the iris that stops when the medication is discontinued but does not regress. It is not a sign of a toxic reaction. It does not indicate an increased risk of developing migraines. It will not reverse.
