Quizplus · Accepted Answer

Blood levels of Coumadin will be monitored by checking daily PT and INR (in some places,only INR).The INR is critically high.The K⁺ is normal and is not monitored for Coumadin therapy.The PT is used in some facilities to monitor Coumadin therapy.Hemoglobin would be important to assess because a side effect of Coumadin is bleeding,and a dropping hemoglobin level would indicate that bleeding was occurring.PT and hemoglobin are within the normal range.
