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 eje [Show Less]
