What is the difference between subjective and objective data in nursing care?

Subjective data is information that is derived from the patient’s personal experiences, perceptions, and feelings. It includes statements such as, "I feel dizzy" or "I am in pain." This type of data cannot be measured or quantified directly; rather, it reflects the patient's perspective and relies on their own input.

Objective data, on the other hand, consists of information that can be observed, measured, and verified. This includes vital signs, laboratory results, physical examinations, and any observable evidence of health conditions. Objective data provides a more concrete basis for assessment because it relies on factual information that healthcare providers can gather through various tests and evaluations.

This distinction is fundamental in nursing, as it allows healthcare professionals to gather comprehensive information about a patient's condition. Both subjective and objective data are essential for holistic assessment and guiding patient care, with subjective data providing context to objective findings. In this way, the correct choice effectively encapsulates the definitions and importance of these two types of data in nursing practice.
