NR324 ADULT HEALTH ROK 2

Name: _______________________________________________ Date: ___________________ 1.Describe the purpose, normal range, significance of results, and nursing responsibilities for these hematological diagnostic and clotting studies: (hemoglobin, Hematocrit, WBC, Total RBC, Platelet count, activated clotting time (ACT), PT, and INR, Lipid profile (cholesterol, LDL, HDL), BUN and Creatine (How abnormal values relate to HTN and Heart failure), Troponin, BNP. Specific Tests Hemoglobin Hematocrit WBC Total RBC Platelet count Activated clotting time (ACT) Normal Ranges F: 11.7-16.0 g/dl (117-160 g/dl) M: 13.2-17.3 (132-173) F: 35%-47% M: 39%- 50% 4,000- 11,000 F: 3.8-5.1 x 10^6 M: 4.3-5.7 x 10^6 150,000- 400,000 70-120 sec SignificanceResults of Nursing Responsibilities Measurement of gas-carrying capacity ofRBC Measure of packed cell volume of RBCsexpressed as a percentage of the total blood voume Measurement of total number of leukocytes Number of circulating RBCs Reduced in cases of anemia, hemorrhage, and hemodilution Increases in Hgb are found in polycythemia or in states of hemoconcentration, which can occur from dehydration Determined by spinning clood in a centrifuge which causes the RBC to settle to the bottom and the plasma to go on top. Hct is the % of red blood cells in it Counts over 11,000 is sign of infection, inflammation, tissue injury or death and malignancies. RBC is altered by the same things that raise and lower the Hgb and Hct levels Number of patelets available to maintain platelet clotting functions Evaluation of intrinsic coagulation status. More accurate than aPTT. Used during dialysis, Counts below 100,000 signify thrombocytopenia which may cause bleeding. Spontaneous hemorrhage may occur if counts get below 10,000. Thrombocytosis is excessive platelets, occurring with inflammation and excessive clotting
