CVRN-BC / CARDIAC VASCULAR NURSING CERTIFICATION (CV-
BC™ Questions With Answers
START OF EXAM
1. The American Nurses Credentialing Center (ANCC) awards which credential upon
successful completion of the cardiac-vascular nursing certification exam?
A) CVRN-BC
B) CV-BC™
C) CCRN
D) CMC
ANSWER Key:
1. B) CV-BC™
Rationale: The ANCC awards the Cardiac Vascular Nurse-Board Certified (CV-BC™)
credential. Other credentials, like CVRN-BC, are offered by other bodies.
2. What is a primary function of the vascular endothelium in a healthy state?
A) Promoting platelet aggregation
B) Vasoconstriction
C) Maintenance of vascular tone and barrier function
D) Synthesizing clotting factors
ANSWER Key:
, 2. C) Maintenance of vascular tone and barrier function
Rationale: The endothelium is a dynamic organ that regulates vascular tone,
maintains a non-thrombogenic surface, and controls the passage of substances
between blood and tissues.
3. The cardiac cycle's phase of ventricular relaxation and filling is known as:
A) Systole
B) Diastole
C) Ejection
D) Isovolumic Contraction
ANSWER Key:
3. B) Diastole
Rationale: Diastole is the period when the heart muscle relaxes and the ventricles
fill with blood.
4. Which of the following best defines cardiac preload?
A) The resistance the ventricle must overcome to eject blood
B) The volume of blood in the ventricles at the end of diastole
C) The force of contraction independent of stretch
D) The amount of blood ejected with each heartbeat
ANSWER Key:
4. B) The volume of blood in the ventricles at the end of diastole
Rationale: Preload is the degree of myocardial fiber stretch at the end of diastole,
directly related to the volume of blood returning to the heart.
5. Which heart chamber has the thickest myocardium to generate the highest pressure?
A) Right Atrium
B) Right Ventricle
C) Left Atrium
D) Left Ventricle
ANSWER Key:
, 5. D) Left Ventricle
Rationale: The left ventricle must pump blood against the high resistance of the
systemic circulation, requiring the thickest muscular wall.
6. The coronary arteries fill with blood during which phase of the cardiac cycle?
A) Atrial systole
B) Ventricular systole
C) Ventricular diastole
D) Isovolumic relaxation
ANSWER Key:
6. C) Ventricular diastole
Rationale: During ventricular systole, the coronary ostia are partially occluded by
the aortic valve leaflets. Most coronary blood flow occurs during diastole when the
myocardium relaxes.
7. Jugular venous distention (JVD) above 5 cm H₂O is a classic sign of:
A) Left-sided heart failure
B) Right ventricular failure
C) Aortic stenosis
D) Hypovolemia
ANSWER Key:
7. B) Right ventricular failure
Rationale: Elevated JVD indicates increased central venous pressure, most
commonly due to right ventricular failure.
8. A patient presents with bilateral leg edema, an S3 gallop, and jugular venous distention.
These findings are most consistent with:
A) Unstable angina
B) Constrictive pericarditis
C) Heart failure
D) Deep vein thrombosis
ANSWER Key:
, 8. C) Heart failure
Rationale: These classic signs indicate fluid overload and decreased cardiac
output, hallmark findings in heart failure exacerbation.
9. A systolic murmur that is loudest at the 2nd right intercostal space and radiates to the
carotid arteries is characteristic of:
A) Mitral Regurgitation
B) Aortic Stenosis
C) Pulmonic Stenosis
D) Mitral Valve Prolapse
ANSWER Key:
9. B) Aortic Stenosis
Rationale: The aortic valve is best auscultated at the 2nd right intercostal space.
The murmur of aortic stenosis is systolic and often radiates to the neck.
10. You auscultate a high-pitched, blowing diastolic murmur at the 3rd left intercostal
space. This is most likely:
A) Aortic Regurgitation
B) Mitral Stenosis
C) Tricuspid Regurgitation
D) Aortic Stenosis
ANSWER Key:
10. A) Aortic Regurgitation
Rationale: Aortic regurgitation produces a diastolic murmur, often heard best at the
left sternal border.
11. An S4 heart sound (atrial gallop) is heard during:
A) Early diastole
B) Atrial contraction
C) Ventricular systole
D) Mid-diastole
ANSWER Key:
