A nurse is assessing a client with a history of heart failure who presents with severe edema in the lower extremities. The nurse would document the presence of +4 pitting edema after noting which finding?

A. +4 pitting edema is characterized by severe pitting that creates a deep indentation (greater than 8 mm) that remains for a prolonged period. This description matches the findings in option A. B. This describes +1 pitting edema, which is not consistent with +4 edema. C. This option describes +2 or +3 pitting edema, as the indentation subsides rapidly, which does not align with +4. D. Although this describes deep pitting, the depth is less than 8 mm, which is not consistent with +4 edema.
