A nurse is caring for a client who reports a decrease in central vision. The nurse should identify that this is a manifestation of which of the following visual impairments?
Macular degeneration
Glaucoma
Diabetic retinopathy
Cataract
The Correct Answer is A
Choice A Reason: This is correct because 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.
Choice B Reason: This is incorrect because glaucoma is a condition that affects the optic nerve, which is the nerve that connects the eye to the brain and carries visual signals. Glaucoma can cause increased pressure inside the eye, damage to the optic nerve, and loss of peripheral vision.
Choice C Reason: This is incorrect because diabetic retinopathy is a condition that affects the blood vessels in the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses. Diabetic retinopathy can cause bleeding, swelling, or leakage of fluid in the retina, and loss of vision in any part of the visual field.
Choice D Reason: This is incorrect because cataract is a condition that affects the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataract can cause clouding or opacity of the lens, and reduced vision in all parts of the visual field.

Correct Answer is C
Explanation
Choice A Reason: This is incorrect because a blister-like pustule on the face that oozes clear fluid may indicate impetigo, which is a bacterial skin infection, not basal cell carcinoma. Basal cell carcinoma is a type of skin cancer that arises from the basal layer of the epidermis, which is the outermost layer of the skin. Basal cell carcinoma lesions are usually not blistered or pustular, but rather smooth, shiny, or waxy.
Choice B Reason: This is incorrect because a dark brown lesion that is flat may indicate a mole, which is a benign growth of melanocytes, which are cells that produce pigment, not basal cell carcinoma. Basal cell carcinoma lesions are usually not dark brown or flat, but rather flesh-colored, pink, or red, and may have a raised or indented center.
Choice C Reason: This is correct because a small scaly, dry lesion on the elbow may indicate basal cell carcinoma. Basal cell carcinoma lesions are often small, scaly, and dry, and may bleed or crust over. They can occur anywhere on the body, but are more common on areas that are exposed to the sun, such as the face, neck, arms, or legs.
Choice D Reason: This is incorrect because location on the top of the head where exposed frequently to sunlight may indicate squamous cell carcinoma, which is another type of skin cancer that arises from the squamous layer of the epidermis, not basal cell carcinoma. Squamous cell carcinoma lesions are usually rough, scaly, or crusted, and may have a firm or hard texture. They can also occur anywhere on the body, but are more common on areas that are exposed to the sun.
Correct Answer is B
Explanation
Choice A Reason: This is correct because eating frequent small meals can help the client with IBS to avoid overloading the digestive system and triggering diarrhea. The nurse should advise the client to eat slowly and chew well, and avoid foods that are spicy, fatty, or gas-producing.
Choice B Reason: This is incorrect because increasing the intake of leafy greens and other sources of dietary fiber can worsen diarrhea by increasing stool bulk and motility. The nurse should advise the client to limit or avoid high-fiber foods, such as whole grains, fruits, vegetables, nuts, and seeds, during acute flare-ups of IBS. The client can gradually reintroduce fiber when the symptoms subside.
Choice C Reason: This is correct because increasing fluids can help the client with IBS to prevent dehydration and electrolyte imbalance caused by diarrhea. The nurse should advise the client to drink at least 8 glasses of water per day and avoid caffeinated, alcoholic, or carbonated beverages that can irritate the bowel or cause gas.
Choice D Reason: This is correct because taking prescribed medications on schedule can help the client with IBS to regulate bowel patterns and reduce diarrhea. The nurse should instruct the client on how to use medications, such as antidiarrheals, antispasmodics, or probiotics, as ordered by the provider. The nurse should also monitor the client for any adverse effects or interactions of the medications.
