MEDICAL ASSISTANT CERTIFICATION EXAM LATEST 2026
UPDATED QUESTIONS AND VERIFIED 100% SOLUTIONS
(2026/2027) GRADE: A+|STATUS: GUARANTEED PASS
what is ischemia? - Answers -insufficient blood supply to the myocardium
what is myocardial infarction (MI) - Answers -sudden death of myocardial tissue due to an
abrupt cessation of blood flow
What are the 2 ischemic EKG characteristics? - Answers -1. subendocardial ischemic injury is
manifest by ST segment depression
2. subepicardial and transmural injury is manifested by ST segment elevation
myocardial infarction EKG - Answers -Notice ST segment depression in aVL leads on the trace;
note that changes in ST segments and T wave inversion are the early signs of myocardial
infarction
the World Health Organization (WHO) criteria for diagnosis of myocardial infarction are
presence of at least two of the following? - Answers --clinical history of ischemic-type of chest
discomfort
-changes on serial EKG tracings
-rise and fall in serum cardiac markers

,what is artifact? - Answers -unwanted interference or jitter on the EKG rcording
what are the 4 common artifacts? - Answers -1. somatic tremor
2. wandering baseline
3. 60-cycle interference
4. broken recording
somatic tremor - Answers -notice jittering pattern on the aVR and aVL leads
wandering baseline - Answers -the iso-electric line moved up and down strip
60-cycle interference - Answers -caused by improperly grounded electrical equipment
broken recording artifact - Answers -caused by a damaged wire or loose electrodes
What are two methods of stress testing? - Answers --exercise stress test
-pharmacologic stress test

,what is ambulatory EKG monitoring used for? - Answers -diagnosis of cardiac dysrhythmias and
can evaluate the HR, rhythm and function during daily activites using a Holter monitor
what is a Holter monitor - Answers -ambulatory EKG where 5 electrodes are attached to
patient's trunk instead of arms and leg to prevent muscle artifact
What are the 10 cardiovascular agents? - Answers -1. oxygen
2. epinephrine
3. isoproterenol (Isuprel)
4. Dopamine (intropin)
5. Beta Blockers
6. Lidcocaine
7. Verapamil
8. Digitalis
9. Morphine sulfate
10. nitroglycerin
what is the cardiovascular agent given to all paitents with angina pectoris (acute severe chest
pains) - Answers -oxygen
what sympathetic drug is used to manage cardiac arrest by increasing heart contractibility? -
Answers -epinephrine
3|Page
, what do beta blockers do? - Answers -reduce heart rate, blood pressure, myocardial
contractility, and myocardial oxygen consumption
what cardiovasular agent produces an overall increase in heart rate and myocardial
contractility? - Answers -isoproterenol
which drug is used in cases with hypotension that causes vasoconstriction? - Answers -
dopamine
what is the drug of choice for the suppression of ventricular ectopy contractions? - Answers -
lidocaine
what is Verapamil used to treat? - Answers -paroxysmal supraventricular tachycardia (PSVT)
digitalis increases the force of what? - Answers -cardiac contraction as well as cardiac output
morphine sulfate is the traditional drug of choice for what? - Answers -pain and anxiety
what is nitroglycerin? - Answers -powerful smooth muscle relaxant
