Nursing Lab Values: CBC, Hgb, Hct, WBC

• A True or False quiz based on nursing lab values is presented.

CBC (Complete Blood Count)

• The CBC includes measurements of white blood cells, red blood cells, and platelets.

Hgb (Hemoglobin)

• Measuring hemoglobin assesses the oxygen-carrying capacity of the blood.
• Normal levels vary based on gender and age.

Hct (Hematocrit)

• Hematocrit is the percentage of red blood cells in the total blood volume.

WBC (White Blood Cell Count)

• The normal range for WBC is typically between 4,000 to 11,000 cells/µL.

Neutrophils

• Neutrophils are a type of white blood cell that help fight bacterial infections.

Lymphocytes

• Lymphocytes are responsible for producing antibodies and defending the body against viral infections.

Monocytes

• Monocytes are involved in fighting viral infections and in the removal of dead or damaged cells.

Eosinophils

• Eosinophils are primarily involved in allergic reactions and parasitic infections.

Basophils

• Basophils play a role in inflammatory reactions and release histamine in allergic responses.

RBC (Red Blood Cell Count)

• The RBC count measures the number of red blood cells in a volume of blood and helps determine anemia.

MCV (Mean Corpuscular Volume)

• MCV measures the average size of red blood cells.

MCH (Mean Corpuscular Hemoglobin)

• MCH measures the average amount of hemoglobin inside each red blood cell.

MCHC (Mean Corpuscular Hemoglobin Concentration)

• MCHC measures the average concentration of hemoglobin in a given volume of red blood cells.

RDW (Red Cell Distribution Width)

• RDW is used to determine the variation in the size of red blood cells.

Platelet Count

• Platelet count is used to evaluate the blood’s ability to clot.

BMP (Basic Metabolic Panel)

• The BMP tests for electrolyte levels, kidney function, and glucose levels.

BUN (Blood Urea Nitrogen)

• BUN measures the amount of urea nitrogen in the blood, which reflects kidney function.

Creatinine

• Creatinine is a byproduct of muscle metabolism and is used to assess kidney function.

KCL (Potassium Chloride)

• Potassium chloride is a medication used to treat low potassium levels, not a lab test.

CL (Chloride)

• Chloride levels in the blood help maintain proper hydration, blood volume, and acid-base balance.

Blood Glucose

• The normal fasting blood glucose level is between 70-100 mg/dL.

Na (Sodium)

• Sodium levels help regulate fluid balance and blood pressure.

Calcium

• Calcium is important for bone health, nerve function, and muscle contraction.
