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?

A. Historical: Historical data refers to past medical or substance use history but does not specifically relate to the client’s current account of their substance use. While this information is relevant, it is not the primary type of data being collected in this instance. B. Objective: Objective data consists of measurable and observable information, such as vital signs, physical examination findings, or laboratory results. The client's account of their cocaine use is not an objective measure but rather a personal statement reflecting their experience. C. Subjective: The client's statement about using cocaine daily for the past 6 months is subjective data. It is based on the client's personal experiences and perceptions, which are important for understanding their substance use pattern and informing treatment planning. D. Secondary: Secondary data refers to information obtained from sources other than the client, such as family members, previous medical records, or other healthcare providers. Since the information is coming directly from the client, it does not qualify as secondary data.
