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?
A. Loss of peripheral vision
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.
B. A decreased ability to perceive colors
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.
C. Loss of central vision
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.
D. Seeing bright flashes of light and floaters
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.

Similar Questions
A client who is suffering from an allergic reaction asks the nurse what can be done about the itching. Which of the following will the nurse provide to the client?
A. Try to avoid scratching
Choice A Reason: This is a correct choice. Trying to avoid scratching is an advice that the nurse will provide to the client, as it prevents further damage and infection of the skin. Scratching can break the skin barrier and introduce bacteria or fungi into the wound, leading to inflammation and complications.
B. Apply a moist cool compress
Choice B Reason: This is a correct choice. Applying a moist cool compress is an advice that the nurse will provide to the client, as it soothes and relieves itching and swelling. A moist cool compress can reduce inflammation and histamine release, which are responsible for allergic symptoms.
C. Use alcohol to cleanse the area
Choice C Reason: This is an incorrect choice. Using alcohol to cleanse the area is not an advice that the nurse will provide to the client, as it irritates and dries out the skin. Alcohol can strip away the natural oils and moisture from the skin, making it more prone to cracking and itching.
D. Use a wooden stick to scratch lesions
Choice D Reason: This is an incorrect choice. Using a wooden stick to scratch lesions is not an advice that the nurse will provide to the client, as it causes more harm than good. A wooden stick can injure or infect the skin, as well as spread the allergen or irritant to other areas.
E. Avoid hot air
Choice E Reason: This is a correct choice. Avoiding hot air is an advice that the nurse will provide to the client, as it aggravates itching and inflammation. Hot air can increase blood flow and histamine release, which are responsible for allergic symptoms. The client should also avoid hot water or showers, as they can have the same effect.

A nurse reviewing a client's chart reads that the client was observed having a complex partial seizure with automatisms of the face. What does the nurse understand this to mean?
A. During a seizure, the client lost bladder control
Reason: This choice is incorrect. Losing bladder control is not a feature of complex partial seizures, but rather of generalized tonic-clonic seizures. Complex partial seizures are a type of focal seizures that affect a specific area of the brain and cause impaired awareness and automatisms. Automatisms are repetitive and involuntary movements or behaviors that occur during a seizure.
B. During a seizure, the client's eyes remained fixed and dilated
Reason: This choice is incorrect. Having fixed and dilated eyes is not a feature of complex partial seizures, but rather of brain death or severe brain injury. Complex partial seizures do not affect the pupils or eye movements, but rather the level of consciousness and motor activity.
C. During a seizure, the client made involuntary groaning sounds
Reason: This choice is incorrect. Making involuntary groaning sounds is not a feature of complex partial seizures, but rather of simple partial seizures. Simple partial seizures are a type of focal seizures that affect a specific area of the brain and do not impair awareness or cause automatisms. They can cause sensory, motor, or psychic symptoms, such as auditory or visual hallucinations, tingling sensations, or emotional changes.
D. During a seizure, the client had involuntary facial movements, such as lip-smacking
Reason: This is the correct choice. Having involuntary facial movements, such as lip-smacking, is a feature of complex partial seizures. Complex partial seizures often originate from the temporal lobe of the brain, which is involved in memory, language, and emotion. They can cause automatisms that affect the mouth, face, or hands, such as chewing, swallowing, picking, or fidgeting.

A nurse is assisting a client with a visual impairment to use the restroom. Which of the following actions will the nurse take to prevent complications?
A. Increase her voice when speaking to the client
reason: This is incorrect because increasing her voice when speaking to the client may not prevent complications, but rather annoy or offend the client. The nurse should not assume that a client with a visual impairment has a hearing impairment as well unless it is confirmed by assessment or history. The nurse should speak in a normal tone and volume and identify herself by name and role.
B. Lower the bed rails before lowering the bed
reason: This is incorrect because lowering the bed rails before lowering the bed may increase the risk of complications, such as falls or injuries. The nurse should keep the bed rails up until the client is ready to get out of bed and lower them only when necessary. The nurse should also lock the wheels of the bed and adjust it to a comfortable height for the client.
C. Use hand gestures to point to where the client will walk
reason: This is incorrect because using hand gestures to point to where the client will walk may not prevent complications, but rather confuse or frustrate the client. The nurse should not use visual cues or gestures that are meaningless to a client with a visual impairment. The nurse should use verbal directions and descriptions instead, such as "The restroom is on your left, about 10 steps away."
D. Stand slightly in front and to one side of the client
reason: This is correct because standing slightly in front and to one side of the client can prevent complications, such as collisions or falls. The nurse should guide the client by offering her arm or shoulder for support and walking slightly ahead of him or her. The nurse should also warn the client about any obstacles or changes in terrain, such as stairs, doors, or rugs.
