The observation regarding a loose bowel movement that is black in color is considered objective data because it is based on measurable and observable facts that can be documented and verified. Objective data consists of information that is not influenced by personal feelings or opinions and can be assessed by anyone through observation or testing.

In this case, the color and consistency of the bowel movement are clear findings that can be seen and recorded accurately. This type of data is important for healthcare professionals to monitor a patient's condition and make informed decisions regarding further assessment or treatment.

Other observations, like the client mentioning feelings of sadness, refusing medication, or reporting a headache, are subjective data. These statements reflect the client’s personal experiences and perceptions, which are valid but not directly observed or measured by the nursing assistant. This distinction helps clarify the difference between the internal experiences of patients and the external, observable signs that healthcare professionals use for clinical assessments.
