NHA CCMA ANSWERS AND QUESTIONS SET A+
✔✔3 skills of the phlebotomist - ✔✔social, clerical, technical
✔✔Analytical errors during collection of blood - ✔✔extended tourniquet time, hemolysis,
wrong order of draw, failure to invert tubes, faulty technique under filling tubes
✔✔Analytical errors before collection of blood - ✔✔Patient misidentification, improper
time, wrong tube, not fasting, exercise (cortisol levels), PT posture, poor coordination
with other treatments, improper side prep, medication interference
✔✔Analytical errors after blood collection - ✔✔Failure to separate serum from cell
(glycolisis), improper use of serum separator (not inverting tubes or not spinning tubes)
delays in processing, exposure to light, improper storage conditions, dimming clots
✔✔Fistula - ✔✔Permanent surgical connection between an artery and a vein, never
used for venipuncture
✔✔Edima - ✔✔Accumulation of fluid in tissue
✔✔Thrombophlebitis - ✔✔Inflammation of a vein with a clot formation
✔✔Explanation of Hemoconcentration - ✔✔The increase in proportion of formed
elements to plasma caused by leaving on the tourniquet for more than two minutes
✔✔Consequence of insufficient pressure applied after withdrawal of needle -
✔✔Thrombus
✔✔additives in green top tube - ✔✔heparin, sodium, litium, ammonium
✔✔Why is the green top tube never used for hematology - ✔✔Green tops additive
heparin interferes with the Wright's stained blood test
, ✔✔Common tests for the lifht blue sodium citrate tube - ✔✔Coagulation studies, PT
(extrinsic, warfarin) APTT, PTT (intrinsic, heparin) TT, BT, FDP
✔✔Common tests for the lavendar edta tube - ✔✔CBC, differential or diff., ESR, sickle
cell screening
✔✔Common tests for this color tube are chemistry tests performed on plasuma such as
Ammonia, carboxyhemoglobin and STAT electrolytes - ✔✔Green top tube (heparin)
Tests
✔✔How long does it take for blood to clot by normal coagulation process in the red top
tube? - ✔✔30-60 mins
✔✔The primary purpose is to provide reliable data about a patients health status by
ensuring the accuracy of a test while detecting and eliminating error - ✔✔What is quality
control
✔✔Common test for the red topped tube - ✔✔Serum chemistry tests, serology tests,
blood bank (glass only)
✔✔Order of draw for cappilary specimens - ✔✔lavender first, then tubes with other
additives, then tubes with out additives
✔✔Antiseptic not used on a dermal puncture site - ✔✔Betadine (because it interferes
with several tests like bilirubin, uric acid, phosphorus and potassium
✔✔For which procedure would you warm the site for a minimum of 3-4 minutes to
increase blood flow? - ✔✔dermal punctures (heel sticks)
✔✔Which are the preferred sites for dermal punctures - ✔✔the distal segment of the
third or fourth finger of the non-dominant hand
✔✔heel sticks are performed on which patients? - ✔✔infants less than 1 year old
✔✔Where on the foot is the dermal puncture made on patients less than a year old -
✔✔the medial and lateral areas of the plantar surface of the foot
✔✔dermal puncture is made in - ✔✔the fleshy portion of the finger slightly to the side of
the center perpendicular to the lines of the fingerprints
✔✔What will occur if you puncture the heel too deep? more than 2 mm -
✔✔osteomyalitis
