SECTION I: HUMAN ANATOMY & PHYSIOLOGY — CARDIOVASCULAR &
LYMPHATIC
• 1. A patient presents with peripheral edema, jugular venous distension, and hepatomegaly.
Echocardiography reveals reduced ejection fraction. Which of the following hemodynamic
parameters would most likely be elevated in this patient's pathophysiology?
• A) Pulmonary capillary wedge pressure
• B) Central venous pressure
, • C) Both A and B
• D) Arterial blood pressure
Rationale: This patient is exhibiting signs of right-sided and left-sided heart failure. Elevated
central venous pressure (CVP) indicates right-sided failure, while elevated pulmonary capillary
wedge pressure (PCWP) indicates left-sided failure. Both are elevated in biventricular failure.
• 2. A researcher isolates a population of cells from the atrioventricular (AV) node. Which
electrophysiological property would these cells MOST prominently demonstrate?
• A) Rapid automaticity
• B) Slow conduction velocity with decremental conduction
• C) Fast upstroke velocity
• D) Absence of spontaneous depolarization
Rationale: The AV node exhibits slow conduction velocity and decremental conduction, which
provides a physiological delay between atrial and ventricular contraction. This property protects
the ventricles from rapid atrial rates.
• 3. Which of the following correctly describes the Frank-Starling mechanism of the heart?
• A) Increased heart rate leads to decreased stroke volume
• B) Increased ventricular end-diastolic volume leads to increased
stroke volume
• C) Decreased afterload leads to decreased cardiac output
• D) Increased contractility leads to decreased stroke volume
Rationale: The Frank-Starling law states that stroke volume increases with increased
ventricular end-diastolic volume (preload) due to optimal overlap of actin and myosin filaments,
resulting in greater force of contraction.
• 4. A patient with liver cirrhosis has decreased synthesis of albumin. Which of the following
compensatory mechanisms would MOST directly maintain oncotic pressure?
• A) Increased aldosterone secretion
• B) Increased ADH secretion
, • C) Increased hepatic synthesis of other plasma proteins
• D) Decreased capillary hydrostatic pressure
Rationale: When albumin synthesis decreases, the liver may increase synthesis of other
plasma proteins (e.g., globulins, fibrinogen) to help maintain plasma oncotic pressure. However,
this compensation is limited, and edema often develops.
• 5. Which of the following correctly describes the relationship between the lymphatic system
and the cardiovascular system?
• A) The lymphatic system produces red blood cells
• B) The lymphatic system returns interstitial fluid and plasma
proteins to the bloodstream
• C) The lymphatic system directly transports oxygen to tissues
• D) The lymphatic system filters arterial blood
Rationale: The lymphatic system is a one-way system that returns interstitial fluid (lymph) and
plasma proteins that have leaked from capillaries back to the bloodstream via the thoracic duct
and right lymphatic duct.
• 6. A patient with a heart murmur is diagnosed with aortic stenosis. Which of the following
pressure gradients would be MOST diagnostic of this condition?
• A) Decreased pressure gradient between left atrium and left ventricle
• B) Increased pressure gradient between left ventricle and aorta
during systole
• C) Decreased pressure gradient between right ventricle and pulmonary artery
• D) Increased pressure gradient between right atrium and right ventricle
Rationale: Aortic stenosis causes obstruction at the aortic valve, creating a significant pressure
gradient between the left ventricle and aorta during systole, which must be overcome to eject
blood.
• 7. Which of the following correctly describes the action potential conduction velocity through
the His-Purkinje system?
• A) 0.5-1.0 m/s
