A client is prescribed a beta blocker as treatment for glaucoma. What should the nurse instruct this client about this medication?
A) Occlude the lacrimal duct after administration.
B) Expect the fingers and toes to tingle.
C) Measure weight daily.
D) Expect to have eye pain.
Answer: A
Since systemic absorption may occur with beta blockers, the nurse should teach the client to close the eyes and occlude the lacrimal duct after administration to help reduce systemic absorption. Carbonic anhydrase inhibitors may cause tingling in the fingers and toes and may affect electrolyte balance, so the client should measure body weight daily. Eye pain is an adverse effect of prostaglandin analogs.
