A nurse is caring for a client who has a new diagnosis of primary open-angle glaucoma and a prescription for timolol ophthalmic drops. For which of the following adverse effects should the nurse monitor the client?

a) Pilocarpine (Ocusert Pilo-20, Ocusert Pilo-40): Pilocarpine is a cholinergic agent used to treat glaucoma, and its use is generally safe for this condition.
b) Atropine sulfate (Isopto Atropine): Atropine is an anticholinergic medication that can increase intraocular pressure, which is contraindicated in glaucoma.
c) Betaxolol (Betoptic): Betaxolol is a beta-blocker that is commonly prescribed to treat glaucoma by decreasing intraocular pressure.
d) Pilocarpine hydrochloride (Isopto Carpine): Pilocarpine is also used to reduce intraocular pressure in glaucoma patients.

a) Allergic rhinitis: Allergic rhinitis typically causes symptoms like sneezing, itchy eyes, and nasal congestion, but it does not typically present with the toothache-like pain or the fullness in the head seen in sinusitis.
b) Impacted wisdom teeth: Impacted wisdom teeth may cause pain in the jaw or gums, but they would not be associated with the fullness in the head or symptoms specific to sinus pressure.
c) Nasal polyps: Nasal polyps can cause nasal congestion or a runny nose, but they usually don't cause the specific symptoms of headache, facial pain, or fullness seen in sinusitis.
d) Sinusitis: The symptoms described (morning headaches, fullness in the head, and pain similar to a toothache under the eye) are indicative of sinusitis, an inflammation of the sinuses, which can cause these specific types of discomfort.
