The first statement is false; the second is true.It is not necessary to observe palpation of skin through light magnification.Note that edema is the presence of fluid in interstitial spaces,which means that fluid has leaked from blood vessels into the spaces between cells.This results in swelling that should be differentiated from fat.A patient with congestive heart failure often has edematous lower legs,and a simple sprained ankle will appear large because of edema.
