A nurse is meeting with a new client at a substance use disorder clinic. During the meeting, the client states that they have been using cocaine at least once daily for the past 6 months. The nurse is collecting which of the following types of data from the client's account?

Rationale: A. Historical data refers to information about past medical history, previous diagnoses, treatments, or events. While the client’s cocaine use over 6 months includes a time frame, the key aspect here is that the information is self-reported, not independently verified, so it is considered subjective rather than strictly historical data. B. Objective data are measurable, observable, or verifiable signs, such as vital signs, laboratory results, or physical exam findings. The client’s self-reported cocaine use is not independently observable, so it is not objective data. C. Secondary data are obtained from sources other than the patient, such as family members, medical records, or healthcare providers. The client’s personal account is a primary source, not secondary. D. Subjective data are information reported by the patient, reflecting their perceptions, experiences, or feelings. The client’s statement about daily cocaine use is self-reported and not directly measurable, making it subjective data.
