Which findings would be expected for an 80-year-old patient? (Select all that apply)

Olfactory and gustatory decline in the elderly results from a reduction in the number of sensory neurons and regenerative capacity. The olfactory bulb undergoes atrophy, while the number of functional taste buds on the tongue diminishes. These changes contribute to nutritional deficiencies as food becomes less palatable. Protective reflexes against spoiled food or environmental hazards are compromised. A. A decreased ability to identify odors: Hyposmia is a common finding in the geriatric population due to a decrease in the number of olfactory receptor neurons. This can affect the enjoyment of food and the ability to detect dangerous smells like smoke or leaking gas. It is an expected age-related change. B. Finer and less prominent nose hair: In the aging adult, nose hairs actually become coarser and stiffer. In men, they may increase in length and prominence. This change can interfere with the filtration of inhaled air and may cause itching or obstruction, rather than becoming finer. C. An increased production of saliva: Aging is typically associated with xerostomia, or decreased saliva production, rather than an increase. This is often exacerbated by medications and systemic conditions. Reduced saliva leads to difficulties in bolus formation, swallowing, and maintains a higher risk for dental decay. D. Hypertrophy of the gums: Gums in the older adult tend to undergo recession rather than hypertrophy. The gingival margin moves toward the root of the tooth, often exposing the cementum. Hypertrophy is usually a pathological finding associated with specific medications or poor oral hygiene, not normal aging. E. A decreased ability to taste differences in food: The decline in both taste bud sensitivity and olfactory function leads to a reduced ability to distinguish flavors. Older adults often find that food tastes bland and may over-compensate by adding excessive salt or sugar. This is a physiological consequence of sensory senescence.
