Final answer:
Objective data in the initial interview includes the patient's heart rate and occupation. Subjective data includes the patient's chief complaint and pain rating.
Step-by-step explanation:
Objective data refers to measurable and observable characteristics of a patient. In the initial interview, the nurse would document the patient's heart rate as objective data because it can be measured using a stethoscope or other instruments. The patient's occupation would also be documented as objective data because it is a factual piece of information that can be confirmed. The patient's chief complaint, on the other hand, is considered subjective data as it is based on the patient's own experience or perception. Lastly, the patient's pain rating would be categorized as subjective data since it is the patient's personal perception of their pain.
