What is the main feature of subjective data?

  1. A. Pathogen characteristics

  2. B. Personal impressions and feelings

  3. C. Blood vessel blockages

  4. D. Restlessness

The correct answer is: B. Personal impressions and feelings

Subjective data refers to information that is derived from an individual's personal experiences, impressions, and feelings. This data is inherently personal and cannot be directly measured or observed. For instance, subjective data might include a patient's report of pain, fatigue, or emotional distress, as they express their personal feelings about their situation or health. This concept contrasts with objective data, which includes facts and measurements such as laboratory results or observations made by healthcare professionals. Therefore, the main feature of subjective data is its reliance on the individual's perspective, making personal impressions and feelings the key characteristic that defines it. The other options represent specific types of data that are generally considered objective or factual rather than subjective. Pathogen characteristics and blood vessel blockages pertain to observable and measurable medical conditions, while restlessness can be observed but does not reflect an individual's personal feelings or impressions directly, making it more of an observed behavior rather than subjective data.
