,Question 1
Which of the following correctly outlines the physiological pathway of blood flow through
the heart?
A) Superior/inferior vena cava -> right atrium -> bicuspid valve -> right ventricle ->
pulmonic valve -> pulmonary vein -> lungs -> pulmonary artery -> left atrium -> tricuspid
valve -> left ventricle -> aortic valve -> aorta
B) Superior/inferior vena cava -> right atrium -> tricuspid valve -> right ventricle ->
pulmonic valve -> pulmonary artery -> lungs -> pulmonary vein -> left atrium -> bicuspid
valve -> left ventricle -> aortic valve -> aorta -> tissues and rest of body
C) Aorta -> left atrium -> tricuspid valve -> left ventricle -> pulmonic valve -> lungs ->
pulmonary artery -> right atrium -> bicuspid valve -> right ventricle -> aortic valve ->
vena cava
D) Superior/inferior vena cava -> left atrium -> bicuspid valve -> left ventricle ->
pulmonic valve -> lungs -> pulmonary artery -> right atrium -> tricuspid valve -> right
ventricle -> aortic valve -> aorta
Answer: B) Superior/inferior vena cava -> right atrium -> tricuspid valve -> right
ventricle -> pulmonic valve -> pulmonary artery -> lungs -> pulmonary vein -> left
atrium -> bicuspid valve -> left ventricle -> aortic valve -> aorta -> tissues and rest
of body
Rationale: Deoxygenated blood returns from systemic circulation via the vena cava to
the right side of the heart, passes through the pulmonary system for oxygenation, and
returns to the left side of the heart to be pumped back out to systemic tissues.
Question 2
The left side of the heart receives what kind of blood?
A) Deoxygenated blood
B) Mixed oxygenated and deoxygenated blood
C) Oxygenated blood
D) Portal blood
Answer: C) Oxygenated blood
Rationale: The left atrium receives freshly oxygenated blood from the lungs via the
pulmonary veins, which is then moved to the left ventricle to be distributed throughout
the body.
Question 3
Which of the following correctly describes the electrical impulse pathway of the heart?
A) AV, SA, Bundle of His, Purkinje fibers
B) SA, AV, Bundle of His, Purkinje fibers
,C) Purkinje fibers, Bundle of His, AV, SA
D) SA, Bundle of His, Purkinje fibers, AV
Answer: B) SA, AV, Bundle of His, Purkinje fibers
Rationale: The electrical impulse originates in the Sinoatrial (SA) node, travels to the
Atrioventricular (AV) node, moves down the Bundle of His, and spreads out into the
ventricular walls via the Purkinje fibers.
Question 4
What is considered a normal resting cardiac output (CO) for an adult?
A) 1–2 L/min
B) 4–8 L/min
C) 10–12 L/min
D) 15–20 L/min
Answer: B) 4–8 L/min
Rationale: Normal adult cardiac output—calculated as stroke volume multiplied by heart
rate—typically ranges between 4 and 8 liters of blood per minute.
Question 5
What is the expected normal value for a resting adult's stroke volume?
A) 25 mL/beat
B) 50 mL/beat
C) 70 mL/beat
D) 120 mL/beat
Answer: C) 70 mL/beat
Rationale: Stroke volume represents the volume of blood pumped from a ventricle with
each contraction, with a normal average resting volume of approximately 70 mL per
beat.
Question 6
Which description best defines the cardiac concept of preload?
A) The resistance the left ventricle must overcome to circulate blood.
B) The amount of blood left in the ventricles after a complete contraction.
C) Amount of blood in ventricles before systole/amount of blood sitting the ventricles at
the end of diastole.
D) The overall force and strength of the myocardial muscular contraction.
Answer: C) Amount of blood in ventricles before systole/amount of blood sitting
the ventricles at the end of diastole.
, Rationale: Preload refers to the stretch or volume of blood inside the ventricles at the
maximum point of filling at the end of diastole, immediately prior to ventricular
contraction (systole).
Question 7
Which term refers to the resistance that the ventricles must overcome to eject blood
during a contraction?
A) Preload
B) Afterload
C) Stroke volume
D) Contractility
Answer: B) Afterload
Rationale: Afterload is the systemic vascular resistance or pressure against which the
heart must pump to open the aortic and pulmonic valves and eject blood.
Question 8
A nurse is evaluating a patient with severe chronic hypertension. The nurse should
understand that hypertension directly increases which component of cardiac workload?
A) Preload
B) Afterload
C) Stroke volume
D) Heart rate
Answer: B) Afterload
Rationale: High systemic blood pressure creates greater resistance in the arteries,
meaning the left ventricle must work much harder to open the aortic valve and push
blood out, directly increasing afterload.
Question 9
A patient is experiencing severe dehydration due to vomiting and diarrhea. Which
impact on cardiac hemodynamics should the nurse anticipate?
A) Increased afterload
B) Increased preload
C) Decreased preload
D) Decreased myocardial contractility
Answer: C) Decreased preload
Rationale: Dehydration results in hypovolemia (reduced blood volume). A lower volume
of circulating blood means less venous return to the heart, which directly decreases
ventricular filling at the end of diastole (preload).
