MULTIPLE CHOICE.
SECTION 1: CARDIAC PHYSIOLOGY & EKG (Questions 1–25)
Question 1: The SA node is observed by what wave on the EKG?
A) T wave
B) QRS complex
C) P wave
D) U wave
Correct answer: C) P wave
Rationale: The SA node initiates the impulse that causes atrial contraction,
represented by the P wave on an EKG. The P wave indicates atrial
depolarization. The QRS complex represents ventricular depolarization, the T
wave represents ventricular repolarization, and the U wave is sometimes seen
in hypokalemia .
Question 2: Depolarization results in which physiological effect?
A) Cardiac contraction
B) Return of chambers to resting state

C) Slowing of heart rate
D) Decreased cardiac output
Correct answer: A) Cardiac contraction
Rationale: Depolarization is the electrical activation of cardiac muscle cells
that results in cardiac contraction. Repolarization, in contrast, is the return of
the chambers to a resting state .
Question 3: Repolarization results in which physiological effect?
A) Cardiac contraction
B) Return of the chambers to a resting state
C) Increased heart rate
D) Increased cardiac output
Correct answer: B) Return of the chambers to a resting state
Rationale: Repolarization is the process by which cardiac muscle cells return
to their resting electrical state after depolarization, allowing the heart to
prepare for the next cardiac cycle .
Question 4: What is normal cardiac output?
A) 2-3 L/min
B) 4-8 L/min
C) 10-12 L/min
D) 15-20 L/min
Correct answer: B) 4-8 L/min
Rationale: Normal cardiac output ranges from 4 to 8 L/min. Cardiac output is
calculated as stroke volume multiplied by heart rate and represents the
amount of blood pumped by the heart per minute .
Question 5: Average stroke volume is:
A) 30-50 mL
B) 60-130 mL
, Page 3 of 39
C) 140-180 mL
D) 200-250 mL
Correct answer: B) 60-130 mL
Rationale: Average stroke volume is approximately 60-130 mL. Stroke volume
is the amount of blood ejected from the left ventricle with each contraction .
Question 6: S1 heart sound is the closing of which valves?
A) Pulmonic and aortic valves
B) Atrioventricular (AV) valves
C) Semilunar valves
D) Tricuspid valve only
Correct answer: B) Atrioventricular (AV) valves
Rationale: S1, the first heart sound ("lub"), is the closing of the
atrioventricular (AV) valves—the mitral and tricuspid valves—at the beginning
of ventricular systole .
Question 7: S2 heart sound is the closing of which valves?
A) Atrioventricular (AV) valves
B) Pulmonic and aortic valves (semilunar valves)
C) Mitral valve only
D) Tricuspid valve only
Correct answer: B) Pulmonic and aortic valves (semilunar valves)
Rationale: S2, the second heart sound ("dub"), is the closing of the semilunar
valves—the pulmonic and aortic valves—at the beginning of ventricular
diastole .
Question 8: Stimulation of the parasympathetic nervous system results in:
A) Increased heart rate
B) Slowing of heart rate
C) Increased cardiac output
D) Vasoconstriction
, Page 4 of 39
Correct answer: B) Slowing of heart rate
Rationale: The parasympathetic nervous system causes vagal nerve
innervation and slowing of heart rate through the vagus nerve (cranial nerve X).
This is part of the body's "rest and digest" response .
Question 9: Blood flow through the right atrium comes from:
A) The pulmonary veins
B) The inferior and superior vena cava
C) The coronary arteries
D) The aorta
Correct answer: B) The inferior and superior vena cava
Rationale: Blood flow through the right atrium is delivered via the inferior and
superior vena cava, which return deoxygenated blood from the systemic
circulation to the heart .
Question 10: The T wave on an EKG represents:
A) Atrial depolarization
B) Ventricular depolarization
C) Ventricular repolarization
D) Early ventricular repolarization
Correct answer: C) Ventricular repolarization
Rationale: The T wave represents ventricular repolarization (the recovery
phase of the ventricles). The P wave represents atrial depolarization, the QRS
complex represents ventricular depolarization, and the ST segment
represents early ventricular repolarization .
Question 11: The QRS complex on an EKG represents:
A) Atrial depolarization
B) Ventricular depolarization
C) Ventricular repolarization
D) SA node firing
