Top Mark Questions and Correct Verified Answers
Advanced Pathophysiology Exam #2
Questions and Correct Verified Answers
Overview of the Blood
✓ •Blood
✓ •5000ml
✓ •Plasma
✓ •3000ml
Hematocrit defined
✓ - % of RBCs
✓ [higher value = higher viscosity = thicker blood)
✓ - Example: Polycythemia may have Hct of 60-70%
Types of Blood Cells
- Erythrocytes [RBCs)
Top Mark !!!
, Top Mark Questions and Correct Verified Answers
✓ - Transport O2
✓ - Small disc shape
✓ - Lifespan = 120 days
✓ - Carry Hgb [ferrous oxide, also an acid/base buffer)
✓ - Made in the bone marrow - Iliac crest for sample in leukemia
✓ [after age 20 in the vertebrae, sternum, ribs, iliac)
✓ - Hgb Levels: 14-16g/dL in males / 12-14g/dl females
Cytic vs Chromic
✓ Cytic = Size of RBCs
✓ Chromic = Amount of Hgb
MCV and MCHC
✓ MCV: Mean corpuscular volume - [average size rbc]
✓ MCHC: normal Mean corpuscular Hgb concentration - [average amount of
hemoglobin in the RBCs compared to the average size of the RBCs. The amount
of hemoglobin that was there
Morphology Size or Erythrocyte Volume Cytic Values

, Top Mark Questions and Correct Verified Answers
✓ - Normocytic: Normal RBC size
✓ [MCV = 83-99)
✓ - Microcytic: Small RBC size
✓ [MCV = 50-82)
✓ - Macrocytic: Large RBC size
✓ [MCV is > 100)
Chromic Values
[Hgb content)
✓ - Normochromic: Normal amount of Hgb [MCHC -Average amount of
hemoglobin in the RBCs compared to the average size of the RBCs.
✓ [MCHC = 32-36)
✓ - Hypochromic: Low amount of Hgb
✓ [MCHC is < 32)
✓ - Hyperchromic: Increased amount of Hgb
✓ [MCHC is > 36)
Leukocytes
[WBCs)
Top Mark !!!
, Top Mark Questions and Correct Verified Answers
✓ - Defend the body against foreign proteins
✓ - Made in the bone marrow
✓ - 9,000/mm^3
✓ - CBC w/ Diff shows: Leukocytes broken down into:
✓ Neutrophils, Basophils, PMNs [polymorphonulcear), Bands
Bands - {Infective process
✓ -Immature Leukocytes
✓ - Indicate an infective process
✓ - Increase in bands = 12 to 20 or more = shift to the left indicating a bacterial
infection
✓ - If bands are not increased it is a shift to the right and a viral infection
Alterations of Leukocytes
Quantitative:
1. Bone marrow dysfunction
2. Premature destruction of cells
a. May originate in lymphoid organs secondary to infectious process
✓ Leukocytosis equals increase WBC's
✓ Leukopenia Equals decreased wbc's
