CCRN PREP EXAM |ACTUAL QUESTIONS AND
VERIFIED ANSWERS 2026-2027 UPDATED
EDITION|GRADED A+
Question 1
A patient is admitted complaining of chest pain and dizziness. A second-degree AV heart
block, Type ll is noted on the ECG. This is most likely the result of occlusion to which
coronary artery?
left circumflex
left anterior descending
Right coronary artery
posterior descending
CORRECT ANSWER
Right coronary artery
Recall that the RCA is the dominant supply to the AV node in 90% of the population. You
would therefore most likely observe ST changes in leads II, III and AVF.
Question 2
The nurse knows that which of the following is contraindicated for a patient requiring
Intra-aortic balloon pump?
ventricular aneurysm
aortic valve insufficiency
ventricular septal defect
mitral valve regurgitation
CORRECT ANSWER
aortic valve insufficiency
Recall the anatomy of the heart valves and the direction and flow of blood.

,Question 3
The nurse is performing a 12-lead EKG for a patient having chest pain. The nurse knows
that lead V4 is placed in which of the following areas:
4th intercostal space, right sternal border
5th intercostal space, left sternal border
5th intercostal space, mid clavicular line
5th intercostal space, mid axillary line
CORRECT ANSWER
5th intercostal space, mid clavicular line
Question 4
A patient is admitted with complaints of severe chest pain. ST elevation in leads V3-V4 is
seen on the ECG. During the PCI procedure, a stent was placed to the LAD. 4 hours later
the patients urine output is oliguric and crackles are auscultated bilaterally. Which of the
following hemodynamic profiles would the nurse expect:
Question 5
CO: 5.1 BP:84/52 SVR:1100 PAP:31/12
CO: 6.7 BP: 92/62 SVR:510 PAP:17/5
CO: 2.9 BP:84/57 SVR:655 PAP:21/15
CO:3.6 BP:83/49 SVR:2180 PAP:42/25
CORRECT ANSWER
CO:3.6 BP:83/49 SVR:2180 PAP:42/25
This patient is presenting with an MI to the anterior/septal wall. First recall the normal
values for these parameters: CO = 4-8L/min. SVR= 700-1500 dynes/sec/cm-5. PAP=

, 25/10. (You MUST memorize these!) Then, recall that conditions causing low SVR
(vasodilation) generally involve septic shock, anaphylaxis, or neurogenic shock. Elevated
SVR (vasoconstriction) generally occurs due to hypovolemia, low cardiac output, or
cardiogenic shock. PA systolic pressures generally reflect lung function, and PA diastolic
pressures generally reflect heart (left-sided) function.
Question 6
Which of the following 12-lead ECG changes should be expected in a patient with acute
coronary syndrome with inferior wall involvement?
ST segment elevation in leads V4 - V6 and deeply inverted T waves in I and aVL
ST segment elevation in leads Il, Ill and all the precordial leads
ST segment elevation in leads II, III and aVF
ST segment depression and T wave elevation in leads Il, Ill and aVL
CORRECT ANSWER
ST segment elevation in leads II, III and aVF
Memorize the lead to vessel correlations: Leads I, aVL, V5, V6 = Lateral Wall = Left
Circumflex Artery Leads II, III, aVF= Inferior wall = Right Coronary Artery Lead V1=
Ventricular Septum = Left Anterior Descending V2, V3, V4= Anterior Wall V1-V4=
Anterior/septal wall
Question 7
A patient was admitted for hypertensive crisis and Nipride was started. The nurse knows
to assess for which of the following:
Thiocyanate toxicity
Uremic encephalopathy
Hyperkalemia
Flash pulmonary edema
CORRECT ANSWER
3

, Thiocyanate toxicity
Question 8
The most effective treatment for patients with acute mitral regurgitation is which of the
following:
Lay the patient flat and elevate the feet
Lasix drip
Epinephrine drip
Intraortic Balloon pump
Nicardipine drip
CORRECT ANSWER
Intraortic Balloon pump
Acute mitral regurgitation is often caused by papillary muscle rupture and usually
presents as a cardiac emergency with the sudden onset and rapid progression of
pulmonary edema, hypotension, and signs and symptoms of cardiogenic shock.
Intraaortic balloon counterpulsation has been used as a temporizing measure prior to
emergency valve surgery in patients with acute MR. TIP: Any test questions with the
word "acute" should point you to the most "acute" or urgent intervention.
Question 9
On the fourth day post-admission, a patient with Q waves in V1, V2 and V3 develops
hypotension, tachycardia and a pansystolic murmur that is loudest at the lower left sternal
border. The patient most likely has:
idiopathic hypertrophic cardiomyopathy.
inferior wall myocardial infarction.
cardiac tamponade.
a ruptured interventricular septum.
