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
Explanation
Choice A Reason: Reporting itching if it becomes bothersome is part of client teaching, as it may indicate inflammation or infection of the ear canal. External otitis is also known as swimmer's ear, as it can be caused by water trapped in the ear after swimming or bathing.
Choice B Reason: Using earplugs when swimming is part of client teaching, as it can prevent water from entering and irritating the ear canal. External otitis can be prevented by keeping the ear dry and avoiding trauma or foreign objects.
Choice C Reason: This is the correct choice. Inserting a cotton-tip applicator to remove excess wax is not part of client teaching, as it can damage or scratch the ear canal and increase the risk of infection. Wax helps protect and lubricate the ear canal and should not be removed unless it causes hearing impairment or discomfort.
Choice D Reason: Using a hairdryer set to low, 6 inches away from ear is part of client teaching, as it can help dry the ear canal after swimming or bathing. External otitis can be treated by applying warm compresses, using topical antibiotics or antifungals, and taking pain relievers or anti-inflammatory drugs.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because airway obstruction is the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Airway obstruction can occur due to edema, inflammation, or inhalation injury of
the upper airway structures. It can compromise oxygenation and ventilation, and lead to respiratory failure or cardiac arrest. The nurse should assess for signs of airway obstruction, such as stridor, hoarseness, dyspnea, or cyanosis, and provide oxygen therapy, humidification, or intubation as needed.
Choice B reason: This is incorrect because fluid imbalance is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Fluid imbalance can occur due to fluid loss from damaged skin and capillaries, as well as increased capillary permeability and fluid shifts. It can cause dehydration, hypovolemia, shock, or electrolyte imbalances. The nurse should monitor fluid status, vital signs, urine output, and laboratory values, and provide fluid resuscitation as prescribed, but only after ensuring airway patency.
Choice C reason: This is incorrect because paralytic ileus is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Paralytic ileus is a condition where there is decreased or absent bowel motility due to nerve damage or decreased blood flow to
the gastrointestinal tract. It can cause abdominal distension, nausea, vomiting, or constipation. The nurse should assess bowel sounds, abdominal girth, and stool characteristics, and provide nasogastric suction or laxatives as prescribed, but only after ensuring airway patency and fluid balance.
Choice D reason: This is incorrect because infection is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Infection can occur due to loss of skin barrier, exposure to microorganisms, or impaired immune system. It can cause fever, increased pain, purulent drainage, or sepsis. The nurse should assess for signs of infection, obtain wound cultures, and administer antibiotics as prescribed, but only after ensuring airway patency, fluid balance, and pain control.
