NHA Exam
A phlebotomy technician is preparing to perform a venipuncture for a patient who has pneumonia.
Besides gloves, what other pieces of PPE should the technician wear? - ANSWER-Face mask;
PPE must be removed and disposed of in the room.
(The tech should wear a face mask when performing a venipuncture for a patient who has a condition
that requires droplet precautions, such as pneumonia.)
While collecting a blood specimen, a phlebotomy tech notices the glass collection tube is cracked. What
action should the technician take? - ANSWER-Dispose of the tube in a sharps container.
(The tech should discard broken glass in a sharps container to reduce the risk of injury.)
A phlebotomy tech is performing a glucometer reading for a young adult patient. The patient's parent is
in the room and asks about the patient's glucose level. What action should the technician take? -
ANSWER-Ask the patient for permission to disclose the results with the parent present.
(The tech should not give the results directly to the patient's parent. Bc the patient is an adult, the tech
should first ask the pt for permission to disclose results.)
A phlebotomy tech is preparing to perform the third set of blood draws for a GTT. The patient starts to
cry and refuses to extend her arm for the draw. What statement should the technician make? -
ANSWER-"May I please perform the draw?"
(The GTT is a timed test that requires multiple blood draws performed at set intervals to adequately
determine values and ranges. The tech should ask the patient for permission to perform the draw, but
should recognize the patient's right to refuse the procedure.)
A phlebotomy tech is preparing to complete the glucose monitor quality control record. Which
information should the technician record in the quality control record? - ANSWER-Date of battery
change.
(The tech should perform daily quality control checks and record the results of these checks and any
other maintenance in the quality control record.)
A phlebotomy tech observes a glucometer reading of 250 mg/dL. A second test is performed and returns
a reading within the expected reference range. What is a circumstance that could have caused the first
result to be inaccurate? - ANSWER-Too much blood was used.
,(If too much blood is applied to a test strip, it can cause false high glucose level readings.)
What solution should be used to clean a cerebral spinal specimen spill? - ANSWER-Chlorine Bleach;
(The tech should use a 1:10 solution of bleach and water to clean a biohazard spill. Chlorine bleach is a
disinfectant and will kill all pathogens.)
A phlebotomy tech experiences a needlestick injury while performing a venipuncture. What information
should the technician include in the online sharps injury log? - ANSWER-The department where the
injury occurred.
(The tech should include the type and brand of the device involved in the injury, the department where
the injury occurred, and a brief explanation of how the injury occurred.)
When testing a pt. for streptococcal pharyngitis, a phlebotomy technician should implement what type
of transmission-based precautions? - ANSWER-Droplet
(The tech should use droplet precautions to prevent the transmission of large-particle droplets, such as
streptococcal pharyngitis.)
What actions should a phlebotomy tech take when performing a blood culture collection? - ANSWER-Use
70% isopropyl alcohol to cleanse the site.
(The tech should scrub the site with 70% isopropyl alcohol. Refer to the study guide addendum on the
NHA website for details on CLSI guidelines for cleansing a venipuncture site.)
What is the current procedure for medical professionals performing CPR on an infant? - ANSWER-30
compressions, 3.8 cm (1.5 in) deep
(A medical professional who is performing CPR on an infant should use two fingers to deliver 30 rapid
compressions at a rate of 100 to 120 compressions per minute that are each 3.8 cm (1.5 in) deep,
followed by two rescue breaths.)
A phlebotomy tech collects a specimen in a microcollection container after two failed venipuncture
attempts. For what reasons should the technician write on the medical requisition form that the blood
was collected in this manner? - ANSWER-To alert the laboratory of the presence of capillary blood.
(In order to obtain correct test results, the lab should be notified as to whether the specimen is capillary
or venous blood.)
, While a phlebotomy tech is using a centrifuge, the device catches on fire. The tech should identify a
centrifuge fire as what class of fire? - ANSWER-Class C
(A Class C fire involves electrical equipment, such as appliances, wiring, and electronics.)
A phlebotomy tech finishes performing a blood draw in an isolation room. What pieces of ppe should the
technician remove first? - ANSWER-Gloves
(The technician should remove the most contaminated piece of PPE first. Therefore, the tech should
remove gloves first.)
A phlebotomy tech is preparing to aliquot a blood specimen. What pieces of PPE are the minimum
requirements for the technician to wear? - ANSWER-Face shield and gloves.
(When aliquoting a blood specimen, the tech should wear protective eyewear, a protective mouth
covering, and gloves. A face shield covers the eyes, nose, and mouth.)
A phlebotomy tech experiences a needlestick injury while performing a draw. The technician is at
greatest risk for exposure to what bloodborne pathogens? - ANSWER-Hepatitis B virus (HBV)
(The tech is at the greatest risk for exposure to HBV. The CDC estimates that the risk of infection is
approximately between 6% to 30%.)
A phlebotomy tech receives a splash of blood to the eyes while transferring serum into an isolator tube.
What action should the technician take first? - ANSWER-Rinse the eyes with water.
(The tech should rinse his eyes with water for 15 min immediately following the incident.)
A phlebotomy tech is collecting a sample for cholesterol, troponin, and HDL blood results. What
department is responsible for processing these tests? - ANSWER-Chemistry
(The chemistry department processes tests related to body chemistry.)
A phlebotomy tech is performing a blood alcohol test (BAL). What antiseptic should the technician use? -
ANSWER-Chlorhexidine gluconate
(The tech should use chlorhexidine gluconate to perform a blood alcohol test bc it does not contain
alcohol.)
A phlebotomy technician is preparing to perform a venipuncture for a patient who has pneumonia.
Besides gloves, what other pieces of PPE should the technician wear? - ANSWER-Face mask;
