What type of data can nurses collect through direct observation?

Nurses can collect data through direct observation, which refers to the ability to see, hear, and assess a patient's physical condition without relying on what the patient or others report. Signs of physical health conditions are objective findings that can be observed and measured, such as swelling, skin color, breathing patterns, or mobility issues. This type of data is crucial for assessing a patient’s health status and determining the appropriate care needed.

In contrast, symptoms reported by patients, personal histories shared by relatives, and patient preferences regarding treatment options involve subjective information obtained through communication rather than direct observation. While these inputs are essential for comprehensive patient care, they do not fall under the category of data that can be collected through direct observation like physical signs do.
