NHA CCMA Study Guide Questions & Answers Graded A+What filing method is used when patient information is highly confidential? Correct Answer: Numerical
1:10 Correct Answer: What is the ratio of bleach and water to use as a disinfectant
The 4 D's of Negligence Correct Answer: Duty, Dereliction, Damages, Direct Cause
The average amount of blood in the human body Correct Answer: 5-6 liters
The number of QRS complexes between 6 sec. marks on the EKG paper is multiplied by 10. Used
generally for estimation slow or irregular rhythms. Correct Answer: 6 second method
The running speed of an EKG machine Correct Answer: 25mm/sec
Boiling water at what temperature is considered a form of disinfected Correct Answer: 212 F
ABO blood group system Correct Answer: a system used to classify human blood by antigens found on
the surface of red blood cells
Abrasion Correct Answer: Scrape of the skin due to something abrasive
absolute refractory period Correct Answer: Is the first phase of repolarization in which a myocardial cell
is unable to react to any electrical stimulus
AD Correct Answer: right ear
Adjustment Correct Answer: the amount the provider would have to write off
Adult pulse range Correct Answer: 60-100 beats/minute
Agents Correct Answer: Are infectious microorganisms that can be classified into groups namely:
viruses, bacteria, fungi, and parasites.
Airborne precautions Correct Answer: Methods of infection control that must be used for patients
known or suspected to be infected with pathogens transmitted by airborne droplet nuclei.
Angina or angina pectoris Correct Answer: Acute Chest Pain
ante Correct Answer: before
antecubital fossa Correct Answer: interior depression of the elbow; blood pressure site and most
common site for drawing blood
Anuria Correct Answer: Little or no urine output
aortic valve Correct Answer: Located between left ventricle and aorta
,Apnea Correct Answer: This is a temporary complete absence of breathing which may be a result of a
reduction in the stimuli to the respiratory centers of the brain
Arterial Blood Gas Studies (ABG's) Correct Answer: Are valuable tools in the treatment of critically ill
patients; used to monitor critically ill patients.
Artifact Correct Answer: an unwanted interference or jitter on the EKG recording. This makes the EKG
reading difficult or impossible, as well as can lead to a misdiagnosis.
AS Correct Answer: left ear
Asystole (cardiac Arrest, Standstill) Correct Answer: the absence of a heartbeat, total absence of
ventricular electrical activity.
Asystole Correct Answer: flat line, absence of a heartbeat
Atrial Depolarization Correct Answer: P wave
Atrial Fibrillation (A-Fib) Correct Answer: common type of heart arrhythmia that is irregular and often
rapid, can exceeds 350 bpm. These rapid impulses cause quivering (fibrillation) of the muscular fibers,
which result in a drastic decrease in the cardiac output, blood stagnation and the form of a clot.
Atrial Flutter Correct Answer: Is characterized by rapid depolarization of a single atrial focus at a rate of
250-350 bpm.
-b/c the AV node cannot transmit every impulse at excessive rates, there is typically a slower ventricular
rate (often appearing at a 2:1, 3:1, 4:1, etc, conduction ratio).
It is an emergency. Notify the Doctor.
Atrial Tachycardia Correct Answer: is caused by an irritable focus in the atria that fires electrical
impulses after the normal firing of the SA node pacemaker HR is between 100-150 bpm
Atrioventricular Blocks Correct Answer: Defined as a delay or interruption of the electrical impulse
conduction beyond the AV node. It is evaluated by measuring the PR interval in EKG traces. The PR
interval is the key of differentiation and classification of the AV blocks
atrioventricular valves Correct Answer: valves between the atria and ventricles
AU Correct Answer: both ears
Augmented Unipolar Leads Correct Answer: record the heart electricity from one limb and compare it
with a zero voltage lead in the center of the heart.
Augmented Voltage Correct Answer: What does the aV in such leads as aVR, aVL and aVF stand for?
Auscultation Correct Answer: listening to sounds within the body
Automaticity Correct Answer: The ability to spontaneously trigger electrical impulses without being
stimulated by another source
,AV node (atrioventricular node) Correct Answer: This node is located at the posterior septal wall of the
right atrium just above the tricuspid valve. There is normally a .12-.20 second delay of electrical activity
at this level to allow blood flow from the atria and fill the ventricles with blood
Avulsion Correct Answer: An injury in which soft tissue is torn completely loose or is hanging as a flap.
Bacteriology Correct Answer: study of bacteria
Barrier protection Correct Answer: Refers to placing a physical barrier between the patients body fluids
(such as blood and saliva) and the healthcare personnel (HCP) to prevent disease transmission.
basilic vein Correct Answer: The third choice for venipunctures. It is the least firmly anchored and
located near the brachial artery. If the needle is inserted too deep, this artery may be punctured.
Basophils Correct Answer: Account for 0-1% of WBC's in the blood. They carry histamines to be released
in case of an allergic reaction.
Battery Correct Answer: The basis of tort in this case the unprivileged touching of one person by
another.
Bicuspid (Mitral Valve) Correct Answer: Is located between the left atrium and the left ventricle. It has
two cusp (or leaflets)
Bipolar leads Correct Answer: Leads I, II, and III
Bloodborne pathogens Correct Answer: Disease-causing microorganisms carried in the body by blood or
body fluids, such as hepatitis and HIV.
Bloodborne Pathogen Standard Correct Answer: -Revision and updating of the exposure control plan
-Solicitation of employee input in selecting engineering and work practice controls
-Modification of definitions relating to engineering controls
-New record keeping requirements
Blood Cultures Correct Answer: They are ordered to detect presence
of microorganisms in the patient's
blood.
Blood Pressure Correct Answer: This is the measurement of the amount of force exerted by the blood
on the peripheral arterial walls and is expressed in millimeters (mm) of mercury (Hg)
Blood Pressure Formula Correct Answer: (cardiac output) x (vascular resistance)
Brachial Pulse Correct Answer: the pulse felt in the upper arm, pulse area of an infant
Bradypnea Correct Answer: Decrease in the number of respirations. This occurs during sleep. It may
also be due to certain diseases
, Bundle Branches Correct Answer: Located at the interventricular septum, the Bundle of His divides the
right and left bundle branches, the function of which is to conduct the electrical impulse to the Purkinje
fibers throughout the ventricles.
Bundle of HIS Correct Answer: Found at the superior portion of the interventricular septum, it is the
pathway that leads out of the AV node and connects to the Bundle Branches.
Capitation Correct Answer: System of payment used by managed care plans in which physicians and
hospitals are paid a fixed, per capita amount for each patient enrolled over a stated period regardless of
the type and number of services provided; reimbursement to the hospital on a per-member/per-month
basis to cover costs for the members of the plan.
Cardiac cell properties Correct Answer: automaticity, excitability, conductivity, contractility
Cardiac output Correct Answer: The volume of blood ejected from the left side of the heart in one
minute.
cardiopulmonary resuscitation Correct Answer: Most healthcare institutions require their professionals
to be certified in CPR.
cephalic vein Correct Answer: The 2nd choice. It is usually more difficult to locate and has a tendency to
move, however, it is often the only vein that can be palpated in the obese patient.
Chambers of the Heart Correct Answer: right atrium, right ventricle, left atrium, left ventricle
Chemical Sterilization Correct Answer: Uses the same chemical used for disinfection, but exposure time
is longer.
Cheyne-Stokes Correct Answer: Regular pattern of irregular breathing rate
Chilled Specimens Correct Answer: Some tests require that the specimen collected by chilled
immediately after collection in crushed ice or ice and water mixture.
Chilled Specimen Tests Correct Answer: Arterial Blood Gases, Ammonia, Lactic Acid, Pyruvate, ACTH,
Gastrin, Parathyroid Hormone
Chlorhexidine Correct Answer: Antiseptic agent used to clean the skin before a blood culture draw

and debris up and out of the airways.
Closed Fracture Correct Answer: broken bone with no open wound
CMS Correct Answer: Centers for Medicare and Medicaid Services
CMS-1500 Correct Answer: most common health insurance claim form used to file claims for physicians'
services
