Final answer:
Subjective assessment data best supporting an anxiety diagnosis include reports of needing to leave and feeling something is terribly wrong, as they reflect personal distress. Objective signs like elevated heart rate offer important clues but lack the personal context provided by subjective symptoms.
Step-by-step explanation:
Subjective assessment data most supportive of a client's diagnosis of anxiety are those which capture the client's personal experience of distress. While vital signs such as an apical pulse rate (which can be objectively measured) provide important clues, the subjective report of needing to leave and feeling that something is terribly wrong are direct expressions of the client's psychological state. These subjective statements reveal the client's internal feelings of fear, unease, and urgency, characteristic of anxiety disorders.
Patients like the one mentioned, expressing symptoms such as weight loss, profuse sweating, increased heart rate, and difficulty sleeping, demonstrate physiological responses that align with anxiety. However, the most indicative of these would likely be the reports of needing to leave and a pervasive sense that something is wrong, as they cannot be quantified but deeply reflect the individual's psychological state.
When considering objective versus subjective data, it's crucial to acknowledge that objective signs can be directly observed and measured, such as heart rate and sweating (diaphoretic skin), whereas subjective symptoms are reported by the patient and cannot be directly confirmed, as seen in both clinical vignettes provided.
