A nurse is completing an assessment of a 78-year-old client's face, ears, nose, and mouth. Which of the following is an unexpected finding in an older adult client during a physical assessment?

A. "My eyes have been feeling dry and itchy, especially in the morning" reflects dry eye syndrome or allergic conjunctivitis. These conditions are generally chronic and manageable with interventions such as artificial tears or allergy medications and do not pose an immediate threat to vision.

B. "I've noticed a few floaters and a sudden blind spot in my vision" indicates a potential retinal tear or retinal detachment, which is an ophthalmic emergency. Sudden floaters, flashes of light, or blind spots suggest the retina may be tearing or detaching. If not treated urgently, this can lead to permanent vision loss. Immediate ophthalmologic evaluation and possible surgical intervention are required, making this statement the priority concern.

C. "My eyes feel discomfort after using my contact lenses all day" usually reflects minor irritation, dryness, or corneal abrasions caused by prolonged contact lens wear. While it needs attention, it is not immediately vision-threatening and can typically be managed by adjusting lens use or providing lubricating drops.

D. "I have been getting mild headaches when I read for long periods" is most likely caused by eye strain, uncorrected refractive errors, or poor lighting. This condition is non-urgent and does not indicate acute ocular pathology.

A. Acne develops primarily due to overactive sebaceous glands, hormonal fluctuations, and bacterial colonization of the skin, particularly Propionibacterium acnes. While acne may occur in people of all skin types, genetically high melanin density does not predispose an individual to developing acne. Therefore, it is not a complication specifically associated with increased melanin levels.

B. Contact dermatitis is an inflammatory reaction caused by exposure to irritants or allergens. It is not directly related to melanin density. People with high melanin may experience contact dermatitis similarly to others, but having more melanin does not inherently increase the risk of developing this condition.

C. Darker skin contains higher levels of melanin, which reduces the skin’s ability to synthesize vitamin D from sunlight. While this is a known risk factor for vitamin D deficiency, the question asks specifically about a skin-related complication, not a nutritional or systemic condition. Therefore, vitamin D deficiency is not the most appropriate answer here.

D. Keloids are excessive overgrowths of scar tissue that develop at the site of skin injury, often extending beyond the original wound margins. People with genetically higher melanin density, particularly individuals of African, Hispanic, or Asian descent, have a higher predisposition to keloid formation. The increased melanin is associated with more active fibroblast proliferation and excessive collagen deposition, which contributes to abnormal scarring. Keloids can result from minor skin injuries, surgical incisions, piercings, or even acne lesions.
