Study Notes
Vital Signs Overview
- Vital signs reflect the body's physiological status and are essential for evaluating homeostasis.
- Key vital signs include body temperature (T), pulse rate (PR), respiratory rate (RR), and blood pressure (BP).
Body Temperature
- Measurement of internal heat, indicating health status and homeostatic balance.
- Core temperature refers to deep tissue temperature; surface temperature involves the skin and subcutaneous tissue.
Heat Transfer Mechanisms
- Conduction: Direct heat transfer, minimal heat loss unless immersed in cold water.
- Convection: Heat dispersion through air currents, e.g., using an electric fan.
- Radiation: Indirect heat transfer without contact; primarily through infrared rays.
- Vaporization: Evaporation of moisture from the respiratory tract and skin.
Purposes of Measuring Vital Signs
- Monitor body functions and detect changes that may not be immediately observable.
- Establish baseline data for patient conditions.
- Aid in diagnosing health issues.
- Guide therapeutic interventions following nursing assessments.
Timing for Vital Signs Assessment
- Upon admission to capture baseline data.
- When a patient’s health status changes or they report symptoms like chest pain.
- Pre- and post-surgery or invasive procedures.
- Before and after administering medications affecting respiratory or cardiovascular systems.
- As per nursing or medical orders and health institution policy.
Temperature Measurement Considerations
- Oral temperature is typically around 37°C (98.7°F).
- Wait 20-30 minutes after eating hot/cold food or drinks before measuring temperature.
- Typically about 1°F higher than core body temperature.
Contraindications for Oral Temperature Measurement
- Not suitable for children under 7 years old.
- Patients who are delirious, mentally ill, or uncooperative.
- Patients in severe pain or those who have had mouth surgery.
