Study Notes
Vital Signs
- Four main vital signs monitored include temperature, pulse, respiration rate, and blood pressure.
- Pain is often considered the fifth vital sign due to its significance in patient assessment.
Body Temperature
- Core body temperature reflects the temperature of deep tissues, typically measured rectally or via other internal methods.
Hormones and Metabolism
- Thyroid gland secretes thyroxine (T4), which significantly increases metabolic rate.
- Increased metabolic rate is also influenced by physical activity, specifically through muscle contractions.
Pain as a Vital Sign
- Recognizing pain as a vital sign enhances patient focus and management, allowing for comprehensive health assessments.
Monitoring Additional Indicators
- Oxygen saturation is commonly monitored alongside traditional vital signs to assess respiratory function.
Role of Fever
- Fever plays a crucial role in the immune response, helping to fight infections by enhancing body temperature.
Heat Transfer Processes
- Conduction results in direct heat transfer, exemplified when a warm hand touches cold metal and heat moves to the metal surface.
Mechanism of Cooling
- Evaporation, through the process of sweating, cools the body as moisture evaporates from the skin surface, dissipating heat.
Factors Influencing Body Temperature in Elderly
- Low-normal body temperature in elderly individuals may arise from factors such as decreased metabolic rate, altered thermoregulation, or chronic health conditions.
Thyroxine and Cellular Metabolism
- Increased thyroxine output boosts cellular metabolism, leading to enhanced utilization of nutrients and energy production.
Insulin's Role
- Insulin directly affects liver and muscle cells, promoting glucose uptake and contributing to an overall increase in metabolic activity.
