Final answer:
Vital signs, such as body temperature and heart rate, are objective data. However, complaints, pain, and bowel sounds can be subjective or objective depending on the method of measurement.
Step-by-step explanation:
Vital signs are considered objective data as they are measurable and can be directly observed by a clinician. They include body temperature, heart rate, breathing rate, and blood pressure. Any changes in vital signs may indicate a disease.
On the other hand, complaints and pain are subjective and cannot be clinically confirmed or objectively measured. Complaints are symptoms reported by the patient, while pain is felt by the patient and can be quantified using a pain-rating scale or other methods.
Bowel sounds are also objective data as they can be auscultated using a stethoscope to assess the state of a patient's bowel movement and detect any abnormalities.
