Final answer:
The Pain Intensity Measurement (PIM) scale is a subjective measure, which is based on the individual's personal assessment of their pain level.
Step-by-step explanation:
The Pain Intensity Measurement (PIM) scale is an example of a subjective measure. This type of measure is used to quantify symptoms that are felt or experienced by the patient, like pain, but cannot be clinically confirmed or objectively measured. Since pain is a symptom that the patient experiences, and different individuals have varying pain thresholds and perceptions, the PIM scale relies on the patient's personal assessment to rate the intensity of their pain. Objective measures, on the other hand, are based on observable and measurable factors such as heart rate, blood pressure, or skin conductance fluctuations, which can indicate pain through physiological changes.
