网考网试题解析：
Pitting edema is documented as +1 when depression is barely detectable on release of thumb pressure and when foot and leg contours are normal. A detectable depression of less than 5 mm accompanied by normal leg and foot contours warrants a +2 rating. A deeper depression (5 to 10 mm) accompanied by foot and leg swelling is evaluated as +3. An even deeper depression (more than 1 cm) accompanied by severe foot and leg swelling rates a +4. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
