Final answer:
Normal physiological changes in older adults include a decline in visual acuity, memory, increased susceptibility to urinary tract infections, and more frequent awakenings after sleep onset.
Step-by-step explanation:
When the nurse is collecting data from the older adult, normal physiological changes include decline in visual acuity, decline in long-term memory, increased susceptibility to urinary tract infections, and increased incidence of awakening after sleep onset. These changes are a part of the aging process. As individuals enter into late adulthood, they experience a host of biological changes, including sensory declines, reduced muscle strength, slower reflexes, and diminished efficiency in the immune system. Consequently, they are more susceptible to certain health issues like infections and sleep disturbances.
