Observation: Nurses must continually observe patients for any signs of changes in their condition. This includes physical, emotional, and behavioral changes. Measurement: Regular measurement of vital signs, such as blood pressure, temperature, pulse, and respiratory rate, helps in assessing the patient's current status. Documentation: Accurate and timely documentation of all observations and measurements is crucial. This ensures that all healthcare providers have access to the most recent information. Communication: Effective communication with the patient and the healthcare team is essential to ensure that any changes are promptly addressed. Evaluation: Continuous evaluation of the patient's response to interventions helps to determine their effectiveness and the need for any modifications in the care plan.
