CCRN PRACTICE QUESTIONS and Answers
Latest Update 2024
A patient in the ED with complaints of chest pain. The 12-lead
EKG shows ST elevation in leads V3 and V4. Occlusion of the
affected coronary artery most likely would affect perfusion to
which portion of the conduction system?
A. Sinoatrial (SA) node
B. Bachmann's bundle
C. Atrioventricular (AV) node
D. Bundle of His - Correct Answer ✅ LAD so D. bundle of
his
Which of the following is the preferred lead for ST segment
monitoring for a patient with a suspected RCA occlusion?
A.I
B. aVR
C. III
D. V1 - Correct Answer ✅ c. III
Which of the following is not a manifestation of hypertrophic
cardiomyopathy?
,CCRN PRACTICE QUESTIONS and Answers
Latest Update 2024
A. Syncope
B. Murmur that increases with squatting
C. Chest pain
D. Sudden cardiac death - Correct Answer ✅ *B
Classic manifestations of hypertrophic cardiomyopathy are
chest pain, syncope, and an aortic stenosis type of murmur
that decreases when the patient is in a squatting position.
The first manifestation of this condition is occasionally
sudden cardiac death during exercise.
In which quadrant is the mean QRS complex axis located if
the QRS complex is predominantly positive in lead I and
negative in lead aVF?
A. Normal quadrant
B. Left axis deviation quadrant
C. Right axis deviation quadrant
D. Indeterminant quadrant - Correct Answer ✅ *B
,CCRN PRACTICE QUESTIONS and Answers
Latest Update 2024
Because the positive of lead I is the left arm, if the QRS
complex is upright in lead I, the mean QRS axis is to the left.
Because the positive of lead aVF (a unipolar lead) is at the
foot, if the QRS complex is negative in lead aVF, the mean
QRS axis is upward away from the foot. This axis would be in
the upper left quadrant, described as left axis deviation.
A patient becomes apneic and pulseless. CPR has been
initiated, and the monitor shows asystole in two leads. Which
of the following drugs would be used initially?
A. Calcium gluconate
B. Atropine
C. Epinephrine
D. Amiodarone (Cordarone) - Correct Answer ✅ C
After CPR is initiated and an intravenous access is
established, epinephrine should be given. Calcium was used
in the past in asystole but is used today only for
hypocalcemia, calcium channel blocker toxicity,
hyperkalemia, and hypermagnesemia. Atropine is no longer
recommended for asystole. Amiodarone is not indicated in

asystole because asystole is the absolute absence of
irritability.
What is associated w/ Mitral Stenosis
A. Pinkish discoloration of the cheeks
B. Systolic murmur
C. Widened pulse pressure
D. Narrow pulse pressure - Correct Answer ✅ A
Patients with mitral stenosis may exhibit a pinkish
discoloration of the cheeks (i.e., malar blush). Mitral stenosis
causes a diastolic murmur. Widened pulse pressure is
associated with aortic regurgitation. Narrowed pulse pressure
is associated with mitral regurgitation.
Four days after a mitral valve replacement, the patient
develops atrial fibrillation. The nurse initially would:
A. order a 12-lead EKG
B. evaluate the patient for clinical indications of
hypoperfusion.
