White Blood Cells Flashcards
(51 cards)
Forms the first line of defense of the body from invading microorganisms
White Blood Cells (Leukocytes)
- Lab tests for these are common
- During infections and inflammation, changes in these directly or indirectly reflect the patients condition
White blood cells are distinguished from RBC’s by the presence of a ________
-What are the two main groups of WBCs?
Nucleus
1) Granulocytes = Neutrophils, Eosinophils, and Basophils
2) Agranulocytes = Lymphocytes and Monocytes
Process by which WBC differentiation and prolifation occurs.
-Most take place in the bone marrow, except lymphocytes which take place in the bone marrow and in __________
Leukopoiesis
-Thymus
T/F It takes 14 days from blast stafe to release of the mature granulocyte into peripheral blood
True
__Function to combat pyogenic infection
__Function to fight allergies and parastic infections
__Function is to fight hypersensitivity reactions and parasitic infections
__Function to fight viral infections
__Functions to help neutrophils
a) Monocytes
b) Basophils
c) Neutrophils
d) Eosinophils
e) Lymphocytes
c) Neutrophils = pyogenic infections
d) Eosinophils = allergies and parastic infections
b) Basophils = hypersensitivity and parastici infections
e) Lymphocytes = viral infections
a) Monocytes = help neutrophils
T/F Leukocytosis is a decrease in total WBCs
FALSE
- Leukocytosis = increase WBC
- Leukopenia = decrease WBC
Neutrophilic leukocytosis a.k.a. ____________
Neutrophilia
Monocytic leukocytosis a.k.a. ______
Monocytosis
Leukocytosis >10,000 usually indicates what
- Infection
- Inflammation
- Leukemoid reactions
- Leukemia
Occurs when WBC falls below 5,000. What are some causes?
Leukopenia
- Viral infections
- Overwhelming bacterial infections
- Bone marrow disorders
- Antibiotics
WBC counts of __________ indicates infection/inflammation, the body is responding to something with an increase in WBCs.
10,000-18,000
Fever with high white count usually indicates __________
Bacterial infection
Low to moderate fever with decrease in WBC’s is usually a _________
Viral infection
-Antibiotics do the same
Patient presents with RUQ pain, accentuated with fatty foods, etc, indicating gall bladder inflammation. WBC count of 13,000 suggests ___________
Bacterial cholecystitis
Patient presents with sore throat, pus pockets in the tonsillar crypts with a white count of 14,500 likely has a ________ and might be
Bacterial pharyngitis
Streptococcal infection
4 causes of an increased RPI
BPTE
- Blood
- Pus
- Tumor
- Edema
Patient presents with RLQ pain, fever, pain over McBurney’s point, rebound tenderness, etc. White count of 17,000 likely has ________
Appendicitis
Patient presents with difficulty breathing, brown rusty sputum, rales/crackles and increased fremitus/vocal vibrations, etc. with a 14,000 white count. Suggestive of ___________
Bacterial pneumonia
25,000 white count with abdominal signs and symptoms with muscle guarding, hurts so bad can’t straighten up indicates a _________
Hot Abdomen (Acute)
T/F Viral infections are generally worse than bacterial infections
FALSE
- Bacterial are worse than viral (generally)
- Look at Differentials to help determine what the body is reacting to
Patient presents with difficulty breathing, chest pain, opacification in lung fields with a white count of 3,800, consider a ___________
Viral pneumonia
Patient presents with sore throat and a white count of 4,200 think _________
Viral pharyngitis
For the white count differential, the lab tech will smear the blood and count ______ to arrive at the differential
100 cells
White blood cells differential (in order)
- Neutrophils = 50-70%
- Lymphocytes = 20-40%
- Monocytes = 2-10%
- Eosinophils = 3-6%
- Basophils = 0-1%
- Bands = 0-6%
Everything else is zero
