Which lab test is used to monitor the intrinsic pathway? – answer PTT (partial
prothrombin time)
Which lab test is used to monitor the extrinsic pathway? - answerPT (prothrombin time)
aPTT (activated partial thromboplastin time) - answer30-40 seconds
INR - answer1 or less
PTT (partial prothrombin time) - answer60-70 seconds
PT (prothrombin time) - answer10-13 seconds
What drug does PT (prothrombin time) monitor? - answer Warfarin (Coumadin)
What drug does PTT and aPTT monitor? - answer Heparin
Red Blood Cell (RBC) Count - answerFemales: 3.61 - 5.11 million/mm3 (4)
Males: 4.21 - 5.81 million/mm3 (5)
Hematocrit - answerFemales: 36% - 48% (39)
Males: 42% - 52% (45)
Hemoglobin - answerFemales: 11.7 - 15.5 g/dL (13)
Males: 14 - 17.3 g/dL (15)
White Blood Cell (WBC) Count - answer4.50 - 11.1 103/mm3
Absolute Neutrophil Count (ANC) - answer1.5 to 8.0 (1,500 to 8,000/mm3)
Platelets - answer150,000 - 450,000/µL
What does a WBC shift to the left mean? - answer-Indicates that more immature cells
are present in the blood than normal
-Occurs with acute infection, inflammation, or some other significant physical stress
What is anemia? - answerOccurs when there is a reduction in the oxygen-carrying
capacity through either fewer RBCs or a reduction in hemoglobin
, What are symptoms of decreased hematocrit? - answer-Shortness of breath
-Tachypnea
-Tachycardia
-Pallor
-Fatigue
-Dizziness
What are dietary sources of iron? - answer-Meat (especially red meat)
-Dark green leafy vegetables (spinach, broccoli, peas)
-Beets
-Dried beans
-Iron-fortified breakfast cereals and breads
-Cream of Wheat
-Ingesting citrus fruits such as oranges or grapefruits increases the vitamin C intake and
may improve iron absorption
What are clinical manifestations of iron-deficiency anemia? - answer-Fatigue
-Pallor
-Tachycardia
-Tachypnea
-Glossitis (smooth, shiny tongue)
-Koilonychia (spoon-shaped nails)
How is iron-deficiency anemia diagnosed? - answer-A complete blood count (CBC)
demonstrates decreased hemoglobin and hematocrit levels
-Serum ferritin levels less than or equal to 100 ug/L indicate IDA 100% of the time
-Additional diagnostic studies to confirm IDA include serum iron, total iron-binding
capacity (TIBC), serum transferrin receptors, and mean corpuscular volume (MCV)
