PART I · PRACTICE QUESTIONS (70 Questions)
Chapter 1: Cardiovascular System
Q1.
The SA node is considered the heart's pacemaker because:
A) It has the largest cells
B) It spontaneously depolarizes at the fastest rate (60-100 bpm), initiating each cardiac cycle
C) It is located in the left ventricle
D) It receives direct sympathetic input only
Q2.
During systole, the mitral valve is:
A) Open · allowing blood to flow from LA to LV
B) Closed · high ventricular pressure keeps it shut, preventing backflow into the LA
C) Partially open
D) Located in the right side of the heart
Q3.
Cardiac output (CO) is calculated as:
A) Heart rate × Blood pressure
B) Heart rate × Stroke volume
C) Stroke volume / Heart rate
D) End-diastolic volume · End-systolic volume
Q4.
The Frank-Starling law of the heart states that:
A) Heart rate determines cardiac output entirely
B) Within physiological limits, increased ventricular stretch (preload) increases force of contraction
and stroke volume
C) The heart pumps the same volume regardless of filling
D) Afterload is the primary determinant of stroke volume
Q5.
Atherosclerosis primarily affects which layer of the arterial wall?
A) The adventitia
B) The intima · endothelial dysfunction and plaque form in the subintimal space
C) The media
D) The external elastic lamina
Q6.
Which vessel carries deoxygenated blood from the right ventricle to the lungs?
A) Pulmonary vein
B) Pulmonary artery
C) Aorta
D) Superior vena cava

Q7.
Mean arterial pressure (MAP) is calculated as:
A) (Systolic + Diastolic) / 2
B) Diastolic + 1/3 (Systolic · Diastolic) · accounts for diastole being longer than systole
C) Systolic · Diastolic
D) Cardiac output × Heart rate
Q8.
The right coronary artery (RCA) typically supplies:
A) The anterior wall of the LV
B) The inferior wall of the LV, RV, SA node (60%), and AV node (90%)
C) The lateral wall of the LV
D) The interventricular septum (anterior portion)
Q9.
Which electrolyte abnormality would WIDEN the QRS complex on ECG?
A) Hypokalemia
B) Severe hyperkalemia >7 mEq/L · depolarizes resting membrane potential, slowing conduction through
the His-Purkinje system
C) Hyponatremia
D) Hypocalcemia
Q10.
What is the primary role of baroreceptors in cardiovascular regulation?
A) Detect blood oxygen levels
B) Detect stretch in arterial walls (aortic arch and carotid sinus), signaling the medulla to regulate
HR and vascular tone via the ANS
C) Control myocardial contractility directly
D) Regulate blood volume through ADH release
Q11.
Coronary arteries fill primarily during:
A) Systole, when ventricular pressure is highest
B) Diastole · high systolic myocardial wall tension compresses intramural vessels, allowing perfusion
only during diastole
C) Both equally
D) Only during exercise
Q12.
In heart failure with reduced ejection fraction (HFrEF), pathological remodeling includes:
A) Concentric hypertrophy only
B) Eccentric hypertrophy · sarcomeres added in series, ventricular dilation, wall thinning, spherical
remodeling
C) Decreased ventricular wall motion only
D) Pericardial fibrosis
