Final answer:
Radiographers should recognize that gerontologic patients often experience a loss of muscle mass and bone calcium, leading to reduced bone density and increased risk of osteoporosis, as well as potential changes in mental alertness. These factors necessitate adaptations in imaging techniques and safety measures.
Step-by-step explanation:
Gerontologic Changes in Radiography
When working with gerontologic patients, radiographers should be aware of several physical changes that are common with aging. These patients often experience a loss of muscle mass, which is part of the natural process of atrophy where tissues, including those in muscles, lose mass. Additionally, there is a decrease in bone calcium content, contributing to reduced bone density and conditions such as osteoporosis, where bones become thinner, lose strength, and are more susceptible to fractures. Cognitive changes may also occur; however, a decrease in mental alertness can vary greatly among individuals and can be influenced by a range of factors, including neurodegenerative diseases like Alzheimer's, represented in brain imaging that uses radiopharmaceuticals to enhance certain features.
Overall, gerontologic patients present unique challenges due to these changes, and radiographers must adapt their techniques to account for decreased bone density, muscle mass, and possible cognitive changes. This includes implementing shielding and limiting exposure to reduce the risks associated with irradiation, as well as possibly adjusting imaging techniques to accommodate physical frailties.
