QUESTIONS AND DETAILED CORRECT ANSWERS
A+ GRADE
Which of the following on an ECG reflects ventricular heart depolarization?
A) T wave
B) U wave
C) P-R interval
D) QRS wave - (answers)D) QRS wave
Depolarization is the contraction of the heart chambers. During the QRS wave, the
ventricles depolarize, and the atria are repolarized in order to receive blood from
the pulmonary vein and the inferior as well as the superior vena cava
What is the universal standard speed for recording an ECG?
A) 20 mm/second
B) 25 mm/second
C) 30 mm/second
D) 35 mm/second - (answers)B) 25 mm/second
25 mm/second is the "normal" rate of speed that ECG paper moves while passing
the heated stylus to record the cardiac cycles of the patient
What is the purpose of performing a specific gravity on a urine sample?
A) It determines whether the patients diet is high in fat
B) It measures its density when compared with distilled water
C) It screens for glomerulonephritis
,D) It detects the presence of nitrate in the urine - (answers)B) It measures its
density when compared with distilled water
A specific gravity would have an especially high reading because of the WBC
concentration seen in glomerulonephritis
All of the following demonstrate quality control. What is the exception?
A) Proper documentation
B) Testing with control samples
C) Calibrating equipment
D) Treating every customer properly - (answers)D) Treating every customer
properly
The purpose of quality control is to ensure that all services performed, equipment
used, and products used are of adequate quality to give accurate test results
What is the pacemaker of the heart?
A) (SA) sinoatrial node
B) (LB) Left bundle branch
C) (BH) Bundle of His
D) (AV) Atrioventricular node - (answers)A) (SA) sinoatrial node
The SA nose specializes in electrical impulse creation and sets the rhythm of the
hearts contractions.
Which of the following commonly used disinfectants is used in the medical field
and found to be effective against bloodborne pathogens?
A) Radiation
,B) Bleach
C) Dry heat
D) Ethylene oxide - (answers)B) Bleach

water
Which of the following is the most appropriate method for disposing of

C) Place it in a biohazard sharps container located in the room where used
D) Disengage the needle from the syringe, and then dispose of it in the biohazard
sharps container - (answers)C) Place it in a biohazard sharps container located in
the room where used
The sharps container must be puncture-proof, leak-resistant, and rigid. There
should be 1 container located in each examination room and the office laboratory
to avoid transporting sharps
What is the most important step in achieving medical asepsis?
A) Washing hands
B) Using surgical soap to scrub hands
C) Cleaning patient examination rooms with disinfectant
D) Placing soiled linens in an appropriate bag as soon as possible - (answers)A)
Washing hands
Transmission by touching is the most common means of transmitting pathogens
, Which of the following solutions will help prevent the transmission of hepatitis?
A) Fluconazole
B) Household bleach
C) Hydrogen peroxide
D) Isopropyl alcohol - (answers)B) Household bleach
This commonly used chemically approved disinfectant is effective on instruments
and equipment that have direct contact with mucous membrane, their secretions,
and other nonsterile surfaces. Using this solution does not destroy pathogen spores;
however it is effective in inactivating hepatitis B
How often should quality control tests to be done for procedures performed in the
office?
A) Yearly
B) Every 6 months
C) Monthly
D) Daily - (answers)D) Daily
A daily check on the accuracy of the test is performed. Expiration dates are noted,
and testing results are verified to ensure that patients' test results will be accurate
and not in error because of inaccurate equipment
Which organization developed the guidelines for universal precautions?
A) EPA
B) FDA
C) CDC
