A nurse in an ophthalmology clinic is interviewing a client who was referred by his primary care provider for suspicion of cataracts. The nurse should expect the client to report:
Having a decreased ability to perceive colors.
Having a loss of peripheral vision.
Seeing bright flashes of light and floaters.
Loss of central vision.
The Correct Answer is A
Choice A rationale
Cataracts cause the lens of the eye to become cloudy, leading to a decreased ability to perceive colors. This is due to the scattering of light as it passes through the cloudy lens, which reduces the clarity and vibrancy of colors.
Choice B rationale
Loss of peripheral vision is more commonly associated with glaucoma, a condition where increased intraocular pressure damages the optic nerve.
Choice C rationale
Seeing bright flashes of light and floaters is typically a symptom of retinal detachment, a serious condition where the retina pulls away from its normal position.
Choice D rationale
Loss of central vision is often linked to macular degeneration, a condition that affects the central part of the retina responsible for sharp, detailed vision.

Correct Answer is ["A","B","C","D"]
Explanation
Choice A rationale
A nagging cough is one of the seven warning signs of cancer. Persistent coughing or hoarseness can indicate lung cancer or other cancers affecting the respiratory system. It is important to investigate any chronic cough that does not resolve with standard treatment.
Choice B rationale
A non-healing sore is another warning sign of cancer. Sores that do not heal, especially in the mouth or on the skin, can be indicative of skin cancer or oral cancer. These sores may bleed, ooze, or become crusty and should be evaluated by a healthcare provider.
Choice C rationale
A change in moles is a significant warning sign of skin cancer, particularly melanoma. Changes in size, shape, color, or texture of a mole, or the appearance of new moles, should be assessed by a healthcare provider. Early detection of skin changes can lead to prompt treatment and better outcomes.
Choice D rationale
A change in bowel pattern is a warning sign of colorectal cancer. Symptoms such as persistent diarrhea, constipation, or changes in stool consistency or color can indicate an underlying malignancy in the digestive tract. It is important to seek medical evaluation for any unexplained changes in bowel habits.
Choice E rationale
Bloating is not typically included in the seven warning signs of cancer. While bloating can be a symptom of various conditions, including ovarian cancer, it is not one of the primary warning signs used to identify cancer. The focus should be on the more specific signs listed above.
Correct Answer is C
Explanation
Choice A rationale
Applying a non-pressure patch to the affected eye can help protect the eye from further irritation or injury. However, it does not address the underlying issue of purulent drainage, which could indicate an infection that requires immediate medical attention.
Choice B rationale
Cleaning the eye from inner to outer canthus is a standard practice to prevent the spread of infection. However, in this case, the presence of purulent drainage suggests a possible infection that needs to be evaluated by a surgeon.
Choice C rationale
Notifying the surgeon is the priority action because purulent drainage from the eye can indicate a serious infection or complication following surgery. Immediate medical evaluation and intervention are necessary to prevent further complications and ensure proper treatment.
Choice D rationale
Instilling an antibiotic solution in both eyes may be part of the treatment plan for an infection. However, the nurse should first notify the surgeon to get appropriate orders and ensure that the correct antibiotic and treatment plan are followed.
