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 A
Explanation
Choice A Reason: The client needs total nursing care is the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which is a tool that measures the level of consciousness based on eye opening, verbal response, and motor response. A score of 6 indicates severe brain injury and coma, meaning that the client is unresponsive and dependent on others for all activities of daily living.
Choice B Reason: Indicates stable neurologic status is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. A stable neurologic status means that there are no changes in the level of consciousness, vital signs, or neurological signs.
Choice C Reason: The client has a decline in level of consciousness but is able to protect his airway is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. A decline in level of consciousness means that the client is less alert and responsive than normal, but still able to respond to stimuli and maintain airway patency.
Choice D Reason: The client is alert and oriented is not the expected outcome for a client who has a score of 6 on the Glasgow Coma Scale, which indicates severe brain injury and coma. Alert and oriented means that the client is fully awake and aware of person, place, time, and situation.
Correct Answer is A
Explanation
Choice A Reason: "I ate shellfish about 2 weeks ago at a local restaurant." supports the medical diagnosis of hepatitis A, which is an infection of the liver caused by the hepatitis A virus (HAV). HAV is transmitted by fecal-oral route, meaning that it can be contracted by ingesting contaminated food or water, such as raw or undercooked shellfish from polluted waters. The incubation period for hepatitis A is about two to six weeks.
Choice B Reason: "I was an intravenous drug abuser in the past and shared needles." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by sharing needles, syringes, or other injection equipment with infected people.
Choice C Reason: "I had a blood transfusion in 1980 after major abdominal surgery." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by receiving blood transfusions or organ transplants from infected donors. However, since 1992, all donated blood in the United States has been screened for HBV and HCV.
Choice D Reason: "I have had unprotected sex with multiple partners." does not support the medical diagnosis of hepatitis A, but may indicate exposure to hepatitis B or C, which are infections of the liver caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). HBV and HCV are transmitted by blood or body fluids, meaning that they can be contracted by having unprotected sex with infected people. However, sexual transmission of HAV is rare, unless there is contact with fecal matter.
