Unit 5-8 Exam 2 Flashcards
CBC
Complete Blood Count
RBC
-Transport O2 and Co2
HGB
-Iron rich proteins blinds O2
HCT
-% of RBC
WBC
-Measures # and % of WBC
PLTs
-# in body, for normal blood clotting
Electrolytes
K+
-transmission of nerve impulses, smooth and skeletal muscle contraction and maintenance OF CARDIAC RHYTHMS
Hyperkalemia: fatigue, muscle weakness, leg cramps, nausea, vomiting, weak/irrgular pulse, hyperglycemia
Hypokalemia: Irritality, anxiety, abdominal cramping, diarrhea, weakness in lower extremities, irregular pulse cardiac standstill if sudden or sever
Electrolytes
Mg
essential for cellular processes (protein synthesis, blood glucose and blood pressure regulation)
Electorlytes
Na+
Concentration and volume of ECF, water loss/ no Na gain
BUN
Blood Urine Nitrogen
-Measures the amount of urea nitrogen in blood
-commonly use the evaluate kidney function
Fasting Blood Glucose (A1C)
-diagnose DM or pre-DM
Nursing consideration: NPO for 8-10 hours before test
INR/PTT
-measures clotting factors, checks for bleeding problems, assess anticoagulant therapies
-High: risk for bleeding
-Low: risk for clotting
HDL cholesterol
High-density lipoprotein
Good
High numbers decreased risk for atherosclerotic disease
LDL cholesterol
Low-density Lipoprotein
Bad
Elevated levels indicate an increased risk for atherosclerotic
Diagnostic Tests
X ray
ECG
MRA
MRI
Biopsy
WBC
-routine screening, infection, inflammation, blood or bone marrow disorders, monitor treatment that affects WBC count prn
DIFF
describes how many of each type of WBC are in the blood (eosinophils, neutrophils, basophils, monocytes, lymphocytes) to detect specific infections. disorders
RBC
Erythrocyte count
-suspected anemia, polycythemia, routine, prn
HgB
hemoglobin
suspected anemia, polycythemia, routine, prn
Hgb A1c/A1c
glycosylated hemoglobin
-diagnose diabates mellitus or pre diabates mallitus
(reflects how much hgb is saturated with glucose over the past 60-90 days)
