1. What role do lymphocytes play in the blood?: the produce
antibodies by creating memory cells
2. What role do monocytes play in the body?: they find and destroy
germs and eliminate infected cells
3. What role do eosinophils play in the body?: protect the body from
parasites, allergens, and bacteria. Too many cause inflammation in
specific areas of your body
4. What role do basophils play in the body?: defend the body from
allergens/parasites. work closely with the immune system by
releasing enzymes to improve blood flow
5. How long do red blood cells live in the body?: 2-3 months
6. Which diagnostic study tests the life of a red blood cell?: A1c
NUR 204
,7. What are the electrolytes in the blood?: sodium, potassium,
calcium, magnesium, chloride, and bicarbonate
8. What is plasma?: -fluid portions of blood
-transports electrolytes to and from cells
-contains nutrients and proteins
-transports hormones throughout the body
-transports waste products
9. A patient comes into the office for a yearly physical and
complains of persistent fatigue over the last several months.
What test is likely to be ordered for this patient?: CBC to test for
anemia
10. What are the different types of blood samples?: venous, arterial,
and capillary
11. When is an arterial blood sample taken?: to determine
arterial blood gas levels
12.When is a capillary blood sample taken?: glucose, cholesterol
levels, clotting times, hgb, and hct
, 13.What information does a complete blood count (CBC)
provide?: oxygen and carbon dioxide transport and
immune/inflammatory response
14.A patient comes into the ED and the nurse notices several
large hematomas. The patient tells the nurse they are taking
heparin. What test does the nurse expect to be ordered?:
PTT/aPTT
15.A new patient comes in for his first visit. When reviewing

hemoglobin and hematocrit levels are low. What condition
might the nurse suspect?: hemorrhage

Average size of red blood cells

average amount of hgb in an individual RBC
20.What does mean corpuscular hemoglobin concentration
(MCHC) measure?: proportion of an individual erythrocyte occupied
by hemoglobin (relative to the size of the erythrocyte)
21.What is fibrinogen used to monitor?: bleeding disorders and
live disease 31. A patient has a glucose level of 214. What other
laboratory test may be ordered?: liver function tests - excess
glucose is converted to glycogen and stored in the liver
32. What can high levels of BUN indicate?: renal dysfunction,
dehydration, or high protein diet
