A nurse in an ophthalmology clinic is interviewing a client who was referred by his primary care provider for suspicion of cataracts. Which of the following findings is consistent with manifestations of cataracts?
Loss of peripheral vision
A decreased ability to perceive colors
Loss of central vision
Seeing bright flashes of light and floaters
The Correct Answer is B
Choice A reason: This is incorrect because loss of peripheral vision is not a manifestation of cataracts, but of glaucoma. Glaucoma is a condition that causes increased pressure inside the eye and damage to the optic nerve, which can lead to loss of vision in the outer edges of the visual field. The nurse should assess the client's intraocular pressure and visual field test results to rule out glaucoma.
Choice B reason: This is correct because a decreased ability to perceive colors is a manifestation of cataracts. Cataracts are a condition that causes clouding or opacity of the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataracts can reduce the clarity and contrast of vision and make colors appear faded or yellowish. The nurse should ask the client about any changes in color perception or brightness of objects.
Choice C reason: This is incorrect because loss of central vision is not a manifestation of cataracts but of macular degeneration. Macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field. The nurse should assess the client's visual acuity and fundoscopic examination results to rule out macular degeneration.
Choice D reason: This is incorrect because seeing bright flashes of light and floaters is not a manifestation of cataracts but of retinal detachment. Retinal detachment is a condition that occurs when the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses, separates from its underlying support tissue. Retinal detachment can cause sudden flashes of light, floaters, or shadows in the visual field. The nurse should refer the client to an ophthalmologist immediately if retinal detachment is suspected.

Correct Answer is ["C","E","F"]
Explanation
Choice A reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not drive home after glaucoma surgery, as they will have reduced vision and increased sensitivity to light in the operated eye. The nurse should advise the client to arrange for someone else to drive them home.
Choice B reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not lie on the right side when going to bed, as this can put pressure on the operated eye and increase the risk of bleeding or infection. The nurse should advise the client to sleep on their back or on their left side.
Choice C reason: This is correct because the nurse should include this in the postoperative education to
the client. The client should report flashing lights, as this can indicate a complication such as retinal detachment or vitreous hemorrhage. The nurse should instruct the client to call the provider immediately if they see flashing lights.
Choice D reason: This is incorrect because the nurse should not include this in the postoperative education to the client. The client should not nap on their left side when they get home, as this can cause fluid accumulation and increased intraocular pressure in the operated eye. The nurse should advise the client to elevate their head at least 30 degrees when resting.
Choice E reason: This is correct because the nurse should include this in the postoperative education to
the client. The client should avoid housework like vacuuming, as this can cause bending, lifting, or straining that can increase intraocular pressure and affect wound healing. The nurse should advise the client to limit physical activity and follow the provider's instructions on when to resume normal activities.
Choice F reason: This is correct because the nurse should include this in the postoperative education to
the client. The client may see flashes of light in the operated eye, as this is a normal phenomenon caused by stimulation of the retina by gas bubbles or fluid shifts. The nurse should reassure the client that flashes of light are normal and will subside over time.
Correct Answer is A
Explanation
Choice A Reason: Sweating and pallor are early signs and symptoms of dumping syndrome, which is a condition where food moves too quickly from the stomach to the small intestine, causing rapid fluid shifts and hormonal changes. Sweating and pallor are caused by hypoglycemia, which occurs when the high concentration of food in the small intestine stimulates insulin secretion.
Choice B Reason: Abdominal cramping and pain are late signs and symptoms of dumping syndrome, which occur about one to three hours after eating. Abdominal cramping and pain are caused by intestinal distension, spasms, and gas formation.
Choice C Reason: Double vision and chest pain are not signs and symptoms of dumping syndrome, but may indicate other serious conditions, such as stroke or heart attack. Double vision and chest pain should be reported to the provider immediately.
Choice D Reason: Bradycardia and indigestion are not signs and symptoms of dumping syndrome, but may be related to other gastrointestinal disorders, such as gastritis or peptic ulcer disease. Bradycardia and indigestion should be evaluated by the provider for further diagnosis and treatment.
