Q

hematocrit (Hct) or packed cell volume (PCV)

A
  • measures the amount of space RBC take up in the blood by separating plasma and blood cells
  • results expressed as 1% of RBC in a volume of blood

21
Q

hemoglobin (Hgb)

A

consists of a protein (globin) and an iron (heme)

-O2 carrying capacity of blood depends on hemoglobin level rather than RBC count

22
Q

means corpuscular volume (MCV)

A
  • measure the average size of RBC
  • macrocytic, or normocytic
  • helps to differentiate between types of anemia
23
Q

mean corpuscular hemoglobin (MCH)

A

the amount of hemoglobin in an average RBC

24
Q

red cell distribution width (RDW)

A

shows how much variability there is in RBC size and shape

25
Q

platelet (thrombocyte) count

A

measures the number of platelets in each mm3 of blood

26
Q

thrombocytopenia

A

low platelet count

27
Q

thrombocytosis

A

elevated platelet count

28
Q

prothrombin time (PT)

A

measures how long it takes blood to clot

29
Q

INR (international normalized ratio)

A

for warfarin, standardized results of PT test, no matter testing method
-PT and INR used to make decisions for Coumadin dosing

30
Q

PTT (partial thromboplastin time)

A

used to evaluate the response to heparin

31
Q

fasting blood glucose

A

diagnosis and monitoring of diabetes mellitus

32
Q

calcium and phosphorus

A

tests used to evaluate calcium physiology

33
Q

sodium and potassium

A

electrolyte balance tests. important in people with kidney disease and in people taking diuretics

34
Q

total protein and albumin

A

provide information about liver function, kidney disease, infection, nutrition, and certain disorders of the antibody producing cells

35
Q

liver function tests

A
  • bilirubin
  • alkaline phosphate
  • aspartate amino transferase
  • gamma glutamyl transpeptidase
36
Q

BUN (blood urea nitrogen)

A
  • used as an index of glomerular function

- rises in dehydration and acute and chronic renal failure, lowers fluid overload and liver disease

37
Q

creatinine

A
  • normal by product of muscle metabolism, excreted by kidneys at fairly constant level.
  • provides a more sensitive indicator of renal function than BUN
  • increase indicates disorder of kidney function.
38
Q

hemoglobin a1c

A

checks amount of glucose bound to hemoglobin in RBC cells

  • used to diagnose prediabetes or diabetes
  • checks long term control of blood glucose levels in people with diabetes
39
Q

HDL high density lipoprotein

A

good cholesterol

40
Q

LDL low density lipoprotein

A

bad cholesterol

41
Q

microbiology

A
  • used to determine what is causing an infection and how best to treat it
  • testing employs swabs, blood, urine and faces
  • keep inside of containers sterile
  • document that the sample was taken
42
Q

R&M routine and microscopic urinalysis

A

includes colour, clarity, odour, specific gravity, pH, protein, glucose, ketones, red or white blood cells, casts, crystals, bacteria

43
Q

C&S culture and sensitivity urinalysis

A

detect and identify organisms growing in the urine and detect which antibiotics the bacteria is sensitive or resistant to

44
Q

Urine specimens

A

preferably the first voiding of the day

-instruct client to cleanse area around genitals

45
Q

mid stream urine

A

have patient void small amount of urine before beginning to collect sample

46
Q

stool ova and parasites

A

determines the presence of a parasite infection of the intestine

47
Q

fecal occult blood

A
  • detects the presence of blood in the stool
  • used routinely to test for colorectal cancer
  • specifically prepared card is used to certain sample
48
Q

sputum sample specimens

A
  • collect in the morning
  • have patient cough deeply
  • instruct them to expectorate directly into the sterile container
49
Q

wound specimen sample

A
  • cleanse wound

- swab surface (granulation tissue)

50
Q

magnesium test

A

measures the level of magnesium in blood (or sometimes urine)
