Final answer:
Quality describes the characteristics of a symptom, injury, or disease, such as the type of pain experienced. Duration is considered quantitative continuous data, and fever is not a cardinal sign of inflammation.
Step-by-step explanation:
​Quality describes the characteristics of the symptom, injury, or disease. For example, when dealing with pain, the quality might refer to whether it is sharp, dull, throbbing, or shooting. Clinicians may use various scales like the Wong-Baker Faces pain-rating scale or measure skin conductance fluctuations to help determine the quality of a symptom such as pain. These methods attempt to provide a more objective measure of symptoms that are inherently subjective and difficult to quantify.
Duration (amount of time) is quantitative continuous data because it can be measured along a continuum and does not have a finite number of values. As for the stage of disease when a patient begins to show general signs and symptoms, it is referred to as the prodromal period. Lastly, fever is not a cardinal sign of inflammation; the cardinal signs are redness, heat, swelling, and pain.
