Hematocrit - correct answer ✔✔Females: 36% - 48% (39)
Males: 42% - 52% (45)
,Hemoglobin - correct answer ✔✔Females: 11.7 - 15.5 g/dL (13)
Males: 14 - 17.3 g/dL (15)
White Blood Cell (WBC) Count - correct answer ✔✔4.50 - 11.1 103/mm3
Absolute Neutrophil Count (ANC) - correct answer ✔✔1.5 to 8.0 (1,500 to 8,000/mm3)
Platelets - correct answer ✔✔150,000 - 450,000/µL
What does a WBC shift to the left mean? - correct 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? - correct answer ✔✔Occurs 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? - correct answer ✔✔-Shortness of breath
-Tachypnea
-Tachycardia
-Pallor
-Fatigue
-Dizziness
What are dietary sources of iron? - correct 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? - correct answer ✔✔-Fatigue
-Pallor
-Tachycardia
-Tachypnea
-Glossitis (smooth, shiny tongue)
-Koilonychia (spoon-shaped nails)
How is iron-deficiency anemia diagnosed? - correct 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)
What teaching do you need to provide to a client with iron-deficiency anemia? - correct answer ✔✔-
Dietary sources of iron
-Immediately report any signs of bleeding, increasing fatigue, or shortness of breath.
-Daily iron supplements must be taken as prescribed.
-Dangers of lead exposure
-Prenatal teaching about iron intake
