Exam Questions and Answers
urgency (urinary) - ANSWER-the immediate need to urinate
What does the physical examination of urine include? - ANSWER-color, appearance,
and specific gravity
What substance gives urine it's color? - ANSWER-urochrome
When is it necessary to obtain a clean-catch midstream sample? - ANSWER-if the
urine will be cultured and examined for bacteria
What is a 24-hour urine specimen used for? - ANSWER-for quantitative
measurements of specific urinary components and to for the diagnosis of the cause
of kidney stone formation
How is the chemical examination of urine used? - ANSWER-it is used to assist in the
evaluation and diagnosis of kidney function, UTI, carbohydrate metabolism, and liver
function; can also be used to detect the presence of substances that don't normally
appear in urine
leukocyturia - ANSWER-the presence of leukocytes in the urine; accompanies
inflammation of the kidneys and the lower urinary tract
bilirubin - ANSWER-a yellow pigment that is released from the breakdown of red
blood cells
When would an arterial puncture be performed? - ANSWER-in a hospital setting to
assess the oxygen level, carbon dioxide level, and acid-base balance of arterial
blood
Two types of venipuncture performed in medical office? - ANSWER-vacuum tube
method and butterfly method
venous reflux - ANSWER-the backflow of blood (from an evacuated tube) into the
patient's vein
venous stasis - ANSWER-stagnation of normal blood flow
order of venipuncture removal - ANSWER-tourniquet, tube, needle
What is the optimal selection site for a venipuncture? - ANSWER-the median cubital
vein
, Why is the basilic vein the least desirable for venipuncture? - ANSWER-both the
brachial artery and nerve lie underneath the basilic vein and could lead to injury of
either or both during a venipuncture
royal blue stoppered tube - ANSWER-used for the detection of trace elements such
as lead, zinc, arsenic, and copper; contain either EDTA or no additive at all
What is the order of draw? - ANSWER-1. Yellow (sodium polyanetholsulfonate) -
blood culture
2. Light blue (sodium citrate) - coagulation tests
3. Red (none) - chemistries, serology, blood bank
4. Marbled red and gray (serum separator) - most chemistry testing
5. Marbled green and gray (plasma separator gel) - potassium determinations
6. Green (sodium/lithium/ammonium heparin) - blood gas determination or pH
assays
7. Lavender (EDTA) - whole blood hematology/CBC
8. Gray (sodium fluoride and potassium oxalate) - blood glucose and alcohol tests
What are the needle lengths and Gauges for venipuncture? - ANSWER-Gauge: 21-
23 G
Needle length: 1/2-3/4 inch
What is the function of hemoblobin? - ANSWER-to transport oxygen to the tissues of
the body
Tests included in a CBC? - ANSWER-1. WBC
2. RBC
3. Platelet count
4. Hgb
5. Hct

7. Red blood cell indices
polycythemia - ANSWER-a disorder characterized by an abnormal increase in the
number of red blood cells in the blood
Reference range for Hgb? - ANSWER-Female: 12-16 g/dL
Male: 14-18 g/dL
What does the hematocrit test usually screen for? - ANSWER-the hematocrit can be
used as a screening measure for the early detection of anemia
Normal range for hematocrit? - ANSWER-Female: 37%-47%
Male: 40%-54%
What are the five WBCs accounted for in a CBC w/diff? - ANSWER-1. neutrophil
2. eosinophil
3. basophil
4. lymphocyte
