After presentation of age-related macular degeneration (AMD) content by the nurse, which patients' statements indicates understanding? Select all that apply. "Family history is a major risk factor for AMD." "Age-related macular degeneration is related to retinal aging." "People with dark-colored eyes have a higher risk for AMD." "Long-term exposure to ultraviolet light is a risk factor for AM D." "Supplementing with vitamins C and E, beta-carotene, and zinc restores lost vision."

"Family history is a major risk factor for AMD." "Age-related macular degeneration is related to retinal aging." "Long-term exposure to ultraviolet light is a risk factor for AMD." Age-related macular degeneration 黄斑病变is the most common cause of irreversible central vision loss in people above 60 years of age. Some patients with AMD may benefit from supplements of vitamins C and E, beta-carotene, and zinc, which delay progression; however, the supplements do not reverse the disease. People with light-colored eyes, not dark-colored eyes, are more at risk for AMD because light eyes have less pigment, which makes them sensitive to light and can cause AMD; the patient making this statement requires further teaching. AMD is related to retinal视网膜 aging because changes in astrocytes in retinal aging cause retinal ischemia, which leads to AMD. Genetic factors play a major role in AMD; family history is a major risk factor for AMD because multiple genetic variants are involved in AMD. Longterm exposure to ultraviolet light is a risk factor for AMD because long-term exposure may cause retinal detachment.

For the 52-year-old African American patient, which statement reflects understanding of content taught by the nurse on glaucoma prevention?

"I will visit my eye doctor every one to two years."

Which interventions would the nurse perform when administering acetazolamide (Diamox) to a patient with chronic glaucoma? Select all that apply. - Monitor the patient's electrolyte levels. - Ask if the patient is allergic to sulfa drugs. - Avoid use if the patient has a history of asthma. - Caution the patient about decreased visual acuity. - Avoid use if the patient is on high-dose aspirin therapy.

- Monitor the patient's electrolyte levels. - Ask if the patient is allergic to sulfa drugs. - Avoid use if the patient is on high-dose aspirin therapy. Acetazolamide is used to decrease production of aqueous humor. The drug may cause allergic reactions in patients sensitive to sulfa drugs; therefore the nurse should ask the patient if he or she has a history of allergy to sulfa drugs. The drug has a diuretic effect and requires the nurse to monitor the patient's electrolyte levels.

Which statement would the nurse include when teaching a patient the pathophysiology of their open-angle glaucoma? -"The retinal nerve is damaged by an abnormal increase in the production of aqueous humor." -"There is decreased draining of aqueous humor in the eye, causing pressure damage to the optic nerve." -"The lens enlarges with normal aging, pushing the iris forward, which then covers the outflow channels of the eye." -"There is a decreased flow of aqueous humor into the anterior chamber caused by the lens of the eye blocking the papillary opening."

-"There is decreased draining of aqueous humor in the eye, causing pressure damage to the optic nerve." With primary open-angle glaucoma, there is increased intraocular pressure because the aqueous humor cannot drain from the eye. This leads to damage to the optic nerve over time.

The patient with acute glaucoma has a history of high-dose aspirin therapy and has a new prescription for acetazolamide (Diamox). Which medication change would the nurse expect when notifying the provider of the concomitant issue? -The dose of acetazolamide will be decreased by half the dose. -There will not be a prescription change for either of the medications. -Due to potential gastric disturbances, the acetazolamide will be changed. -Administration times will be rescheduled to avoid taking the two medications at the same time.

-Due to potential gastric disturbances, the acetazolamide will be changed.

While performing a medication reconciliation with a newly admitted patient's home medications, the nurse notes the patient is taking pilocarpine eye drops. Which desired effects would the nurse associate with this medication? Select all that apply. -Facilitates aqueous humor outflow -Reverses damage to the optic nerve -Improves the patient's vision in dim light -Lessens the amount of pupillary dilation -Decreases the amount of fluid within the eye

-Facilitates aqueous humor outflow -Lessens the amount of pupillary dilation Pilocarpine is a cholinergic (parasympathomimetic) medication used to treat chronic openangle glaucoma. It causes miosis (pupillary constriction), which improves the flow of the fluid (aqueous humor) within the trabecular meshwork of the eye. This keeps the pressure within the eye low and decreases likelihood of optic nerve damage. Damage to the optic nerve from glaucoma cannot be reversed with treatment. Miotic effects of the medication do not allow for pupil dilation that normally occurs in dim light. Pilocarpine does not decrease the amount of aqueous humor production as do some other medications (β-adrenergic blockers) used to treat glaucoma.

Application of a warm, moist compress four times a day

For which contributing factor would the nurse closely monitor in the patient experiencing retinal hemorrhages, anoxic cotton-wool spots, and macular swelling in the eye? Glucose level BP Intraocular pressure Thyroid hormone levels

BP Hypertensive retinopathy is caused by high BP that creates blockages in retinal blood vessels. The eye examination of a patient with hypertensive retinopathy reveals retinal hemorrhages, anoxic cotton-wool spots, and macular swelling. If the eye examination shows capillary microaneurysms, retinal swelling, and hard exudates, then the nurse will suspect nonproliferative retinopathy and high blood glucose level.

The health care provider's assessment identified optic nerve atrophy and peripheral visual field loss in the patient reporting sudden, severe eye pain accompanied by nausea and vomiting. When providing the patient's discharge instructions, which medication would the nurse correlate with this disorder? Betaxolol (Betoptic) Besifloxacin (Besivance) Tropicamide (Mydriacyl) Ranibizumab (Lucentis)

Betaxolol (Betoptic) Betaxolol is an antiglaucoma drug that decreases intraocular pressure. Besifloxacin is an antibiotic that is used to treat acute bacterial conjunctivitis.
