When assessing a client diagnosed with basal cell carcinoma, which of the following findings will the nurse expect?

Choice A Reason: This is incorrect because full vision loss in one eye does not necessarily mean that the person is legally blind. Legal blindness depends on the visual acuity and visual field of both eyes.

Choice B Reason: This is correct because legal blindness is defined by the World Health Organization (WHO) as having a visual acuity of 20/200 or worse in the better eye with the best possible correction, such as glasses or contact lenses. This means that the person can see at 20 feet what a normal person can see at 200 feet.

Choice C Reason: This is incorrect because inability to see clearly from 200 feet away without corrective lenses may indicate nearsightedness or myopia, but not legal blindness. Nearsightedness can be corrected with lenses or surgery.

Choice D Reason: This is incorrect because bilateral visual impairment of 20/60 or greater does not meet the criteria for legal blindness. Visual impairment is defined by WHO as having a visual acuity of less than 20/60 but better than 20/200 in the better eye with the best possible correction.

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.
