1) Which of the following is not a phlebotomist's duty?
A. Collecting blood specimens
B. Performing laboratory computer operations
C. Starting
... [Show More] intravenous (IV) lines
D. Transporting specimens to the laboratory CORRECT ANSWER 1. C - In the case of intravenous drugs, most cases require a licensed individual to administer this type of therapy. A medical assistant can assist by laying out supplies and equipment necessary for the infusion or injection being administered.
2) A national organization that sets standards for phlebotomy procedures is the:
A. ASCP
B. NAACLS
C. NCA
D. NCCLS CORRECT ANSWER 2. D - All phlebotomy programs are subject to standards which are set by The National Committee for Clinical Laboratory Standards. (NCCLS)
3) Which type of contact infection transmission involves transfer of an infective microbe to the mucous membranes of a susceptible individual by means of a cough or sneeze?
A. Direct
B. Droplet
C. Fomites
D. Indirect CORRECT ANSWER 3. B - Direct transmission occurs through contact with an infected person's mucous membranes. Indirect transmission occurs through contact with a fomite - an inanimate object that is a reservoir for the transmission of microorganisms. For example, a drinking glass.
The droplets from a sneeze are a common way for an infection to be transmitted.
4) Which of the following is a test of the respiratory system?
A. ABGs
B. CSF
C. TSH
D. UA CORRECT ANSWER 4. A - ABG or Arterial blood gas deals directly with the respiratory system. CSF is cerebrospinal fluid and TSH is thyroid stimulating hormone. UA is a distracter.
5) Urine C & S is typically ordered to detect:
A. Abnormal urine pH
B. Glucose spillage into the urine
C. Kidney damage
D. Presence of UTI CORRECT ANSWER 5. D - C&S testing is used for UTI symptoms -must be a mid-stream clean catch specimen.
6) Which statement describes proper centrifuge operation?
A. Centrifuge serum specimens before they have a chance to clot
B. Never centrifuge both serum and plasma specimens in the same centrifuge
C. Place tubes of equal size and volume opposite one another
D. Remove stoppers before placing tubes in the centrifuge CORRECT ANSWER 6. C - Tubes should be balanced in the centrifuge - tubes of the same size and volume are placed opposite one another in the centrifuge holders
7) What type of motion would a phlebotomist use when cleaning a site for a routine venipuncture?
A. Vertical
B. Horizontal
C. Crossing
D. Concentric CORRECT ANSWER 7. D - concentric or circular is the motion necessary for performing phlebotomy.
8) The heart valve that is situated between the right atrium and the right ventricle is called?
A. The pulmonic valve
B. The mitral valve
C. The aortic valve
D. The tricuspid valve CORRECT ANSWER 8. D - see diagram
9) The third step of analyzing an ECG rhythm is:
A. Evaluate the QRS complex
B. Determine the heart rate
C. Determine the regularity
D. Evaluate the P-wave CORRECT ANSWER 9. D- The five steps in analyzing an ECG are: heart rate, regularity, P-waves, QRS complex, and P-R interval.
10) Mrs. Rogers was experiencing a successful venipuncture when petechiae arose on her forearm. This was the result of:
A. Allergy to the antiseptic used to cleanse the area
B. The needle puncturing completely through the vein
C. The tourniquet being applied too tightly
D. A rare genetic disorder CORRECT ANSWER 10. C - When placing the tourniquet on the arm, it is important to not tie too tightly as a petechiae may result. Petechiae are small, red, smooth hemorrhagic spots appearing on a patient's skin. A hematoma occurs when the needle has gone completely through the vein.
11) The PR intervals get progressively longer in:
A. 1st-degree AV heart block
B. 2nd-degree AV heart block, Type I
C. 3rd-degree AV heart block
D. Sinus dysrhythmia CORRECT ANSWER 11. B - Longer P-R intervals indicate the impulse was slowed down more than it should have been usually in the AV node. The PR intervals get progressively longer in a 2nd degree heart block, Type 1. Absent P-R intervals indicate that there are too many impulses in the atria to signify a P-R interval (i.e. atrial fibrillation or flutter).
12) The fifth step of analyzing an ECG rhythm is to:
A. Determine the regularity
B. Examine the P waves
C. Evaluate the PR intervals
D. Determine the heart rate CORRECT ANSWER 12. C- The five steps in analyzing an ECG are: heart rate, regularity, P-waves, QRS complex, and P-R interval.
13) Normal QRS complexes are those that:
A. Look different
B. Are inverted
C. Are wide and bizarre
D. Are upright and narrow CORRECT ANSWER 13. D- Normal ORS complex should be .06 to .12 sec. in duration and 5mm to 30mm in amplitude. A normal QRS complex indicates the impulse originated above the ventricles and traveled through the ventricles in a normal fashion. Normal QRS complexes are those that are upright and narrow.
14) The dysrhythmia that always produces an irregularly irregular rhythm is called:
A. Sinus arrest
B. Ventricular tachycardia
C. Atrial fibrillation
D. 2nd-degree AV heart block, Type I CORRECT ANSWER 14. C- Atrial fibrillation:
Rate: atrial rate over 350bpm, ventricular rate can vary
Regularity: irregularly (totally) irregular;
P-wave: absent (chaotic baseline);
QRS-complex: normal; PR-interval: absent
15) The muscular wall that separates the right side from the left side of the heart is called the:
A. Chordae tendineae
B. Syncytium
C. Septum
D. Skeleton of the heart CORRECT ANSWER 15. C- See diagram [Show Less]
