Question 2.
diagnostic testing
Correct Answer: lab testing- blood, urine, stool, body fluids, biopsy
Question 3.
CBC- complete blood count
Correct Answer: looks at plasma, leukocytes, erythrocytes, hemoglobin A1C,
platelet count, blood
chemistries, comprehensive panel, serum sodium, potassium, chloride, BUN,
creatinine, blood
glucose, serum calcium, TSH, blood culture (cx), drug screens, vitamins and
minerals, allergy panels,
lipids, pregnancy, liver enzymes, HIV and hepatitis screen, rheumatological
labs, cardiac enzymes,
genetic testing, blood type and screen
Question 4.
plasma liquid component of blood,
Correct Answer: made up of mostly water and electrolytes; contains albumin
the major protein component
Question 5.
albumin protein in blood,
Correct Answer: helps maintain the osmotic pressure in the blood, serum levels
gives a rough estimate of overall health and nutritional status
Question 6.
leukocytes white blood cells (5 kinds),
, Correct Answer: all involved with immune response of the body, nucleated
cells, normal WBC count --> 3500-10000
Question 7.
high leukocyte count
Correct Answer: infection (bacterial) and any stress to the system (allergic
reaction), in certain
leukemias
Question 8.
low leukocyte count
Correct Answer: viral infection, immunosuppression (HIV disease)
Question 9.
types of leukocytes
Correct Answer: neutrophils- primary response in bacterial infection, fungal
infection;
lymphocytes- T cells and B cells, B makes antibodies, T fight viruses;
eosinophils- parasites, immune
response (worms, wheezes, and weird diseases);
basophils- histamine release in allergic response (dilates blood vessels);
monocytes- leave
bloodstream and become macrophages (to engulf foreign items)

hemoglobin male 14-18 g/dl and female 12-16 g/dl, hematocrit red cell
volume male 40-54 and female 36-48
Question 11.
high RBC
Correct Answer: count eyrthocytosis, in smokers, CO2 poisoning, high altitude
Question 12.
