A nurse is gathering data during a health assessment. Which of the following is an example of subjective data?

Rationale: A. Blood pressure is objective data because it is measurable, observable, and quantifiable. The nurse can obtain this information using a blood pressure cuff and verify it independently. Objective data are considered factual and can be used to track changes over time or compare against established norms. While critical for patient care, it does not reflect the patient’s personal experience or perception. B. Respiratory rate is also objective data because it can be counted and observed. It provides a concrete measure of physiological function and is not influenced by the patient’s subjective feelings. Objective data like vital signs are crucial for detecting trends, assessing baseline health, and identifying early signs of deterioration. C. The patient reporting feeling nausea is subjective data, meaning it is based on the patient’s personal experience and cannot be directly measured by the nurse. Subjective data include symptoms such as pain, fatigue, dizziness, anxiety, or nausea. This type of information is essential for understanding the patient’s perception of illness, guiding interventions, and planning individualized care. Without eliciting subjective data through careful interviewing, a nurse might miss symptoms that are not apparent through objective measurements alone.
