Final answer:
The process of data collection should begin with a client interview, where the nurse gathers information directly from the patient.
Step-by-step explanation:
The process of data collection should begin with the nurse performing a client interview. This allows the nurse to gather information directly from the patient, which is essential for accurate data collection. Interviewing the patient provides an opportunity to ask questions, gather subjective data, and understand the patient's perspective.
While other steps such as a physical exam, review of medical records, and discussion with other health team members are important in the data collection process, the client interview is the most crucial step as it provides firsthand information from the patient.
