PART I · PRACTICE QUESTIONS (30 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

Q1.
Surfactant is produced by which cells in the lung and what is its primary function?
A) Type I pneumocytes · gas exchange
B) Type II pneumocytes · reduces alveolar surface tension, preventing alveolar collapse at end-
expiration
C) Goblet cells · mucus production
D) Macrophages · immune defense
Q2.
Oxygen is transported in the blood primarily by:
A) Dissolved in plasma (~1.5%)
B) Bound to hemoglobin (~98.5%) · each Hb molecule carries up to 4 O2 molecules
C) Bound to albumin
D) In bicarbonate form
Q3.
The primary muscle of inspiration is the:
A) External intercostals
B) Diaphragm · innervated by the phrenic nerve (C3, C4, C5)
C) Sternocleidomastoid
D) Internal intercostals
Q4.
Carbon dioxide is transported in the blood primarily as:
A) Dissolved CO2 gas in plasma
B) Bicarbonate ion (HCO3·) · about 70% of total CO2 transport
C) Carbaminohemoglobin (~23%)
D) Carbonic acid
Q5.
Residual volume (RV) is:
A) Air inspired in a normal tidal breath
B) Air remaining in the lungs after maximum forced expiration · cannot be expelled and cannot be
measured by spirometry alone
C) Maximum air inspired after normal tidal inspiration
D) Total lung capacity minus tidal volume
Q6.
In pulmonary embolism, V/Q mismatch occurs because:
A) Alveoli are filled with fluid
B) The occluded pulmonary artery stops blood flow to ventilated alveoli · high V/Q (dead space)
C) Bronchospasm reduces ventilation
D) There is perfusion without ventilation
