Final answer:
The correct answer to the question is 'c) 2+' on the edema scale, which indicates an easily identified depression with a rebound time of 1-15 seconds.
Step-by-step explanation:
The question pertains to the grading of edema, which is the swelling caused by fluid accumulation in the body's tissues. On the edema scale, 'c) 2+' represents an edema where an easily identified depression is present, and the skin takes 1-15 seconds to rebound to its normal appearance after being pressed. This condition is significant as the presence of edema can be a sign of various underlying health issues, which may require medical attention. It can often be observed in individuals with conditions that affect the heart, kidney, or liver, and can also result from localized injury.
