Final answer:
A CNA must understand that elderly individuals have a diminished ability to regulate body temperature due to aging and are more susceptible to temperature-related health problems such as heat stroke or hypothermia. Close monitoring of body temperature is vital to provide timely medical intervention.
Step-by-step explanation:
A Certified Nursing Assistant (CNA) needs to have a good understanding of how the body temperature regulation is affected in the elderly due to aging, homeostatic imbalance, and disease. As people age, the efficiency of their body's homeostats diminishes, making them less capable of regulating their body temperature. This can result in the elderly being more susceptible to heat-related illnesses like heat stroke, as well as more serious difficulty when trying to fend off infectious diseases and cancer. Furthermore, due to reduced energy reserves, when faced with cold, elderly individuals might experience detrimental health impacts such as hypothermia or even frostbite if blood flow to extremities is heavily reduced. Therefore, CNAs must carefully monitor the body temperature of elderly patients to detect any signs of fever, infection, or other temperature-related health issues, ensuring rapid and appropriate medical intervention when necessary.
