100 % GUARANTEED SUCCESS
,MS: CARDIOVASCULAR SYSTEM
1. A nurse is assessing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular.
The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64
beats per minute. The nurse assesses the cardiac rhythm as:
A. Normal sinus rhythm
B. Sinus bradycardia
C. Sick sinus syndrome
D. First-degree heart block
2. A nurse notices frequent artifacts on the ECG monitor for a client whose leads are connected by cable
to a console at the bedside. The nurse examines the client to determine the cause. Which of the following
items is unlikely to be responsible for the artifact?
A. Frequent movement of the client.
B. Tightly secured cable connections.
C. Leads applied over hairy areas.
D. Leads applied to the limbs.
3. A nurse is watching the cardiac monitor and notices that the rhythm suddenly changes. There are no P
waves, the QRS complexes are wide, and the ventricular rate is regular but over 100. The nurse
determines that the client is experiencing:
A. Premature ventricular contractions
B. Ventricular tachycardia
C. Ventricular fibrillation
D. Sinus tachycardia
4. A nurse is viewing the cardiac monitor in a client’s room and notes that the client has just gone into
ventricular tachycardia. The client is awake and alert and has good skin color. The nurse would prepare
to do which of the following?
A. Immediately defibrillate.
B. Prepare for pacemaker insertion.
C. Administer amiodarone (Cordarone) intravenously.
D. Administer epinephrine (Adrenaline) intravenously.
5. A nurse is caring for a client with unstable ventricular tachycardia. The nurse instructs the client to do
which of the following, if prescribed, during an episode of ventricular tachycardia?
A. Breathe deeply, regularly, and easily.
B. Inhale deeply and cough forcefully every 1 to 3 seconds.
C. Lie down flat in bed.
D. Remove any metal jewelry.
6. A client is having frequent premature ventricular contractions. A nurse would place a priority on the
assessment of which of the following items?
A. Blood pressure and peripheral perfusion.
B. Sensation of palpitations.
C. Causative factors such as caffeine.
D. Precipitating factors such as infection.
,7. A client has developed atrial fibrillation, which has a ventricular rate of 150 beats per minute. A nurse
assesses the client for:
A. Hypotension and dizziness
B. Nausea and vomiting
C. Hypertension and headache
D. Flat neck veins
8. A nurse is watching the cardiac monitor, and a client’s rhythm suddenly changes. There are no P waves;
instead, there are wavy lines. The QRS complexes measure 0.08 second, but they are irregular, with a
rate of 120 beats a minute. The nurse interprets this rhythm as:
A. Sinus tachycardia
B. Atrial fibrillation
C. Ventricular tachycardia
D. Ventricular fibrillation
9. A client with rapid rate atrial fibrillation asks a nurse why the physician is going to perform carotid
massage. The nurse responds that this procedure may stimulate the:
A. Vagus nerve to slow the heart rate.
B. Vagus nerve to increase the heart rate; overdriving the rhythm.
C. Diaphragmatic nerve to slow the heart rate.
D. Diaphragmatic nerve to overdrive the rhythm.
10. A nurse notes that a client with sinus rhythm has a premature ventricular contraction that falls on the T
wave of the preceding beat. The client’s rhythm suddenly changes to one with no P waves or definable
QRS complexes. Instead, there are coarse wavy lines of varying amplitude. The nurse assesses this
rhythm to be:
A. Ventricular tachycardia
B. Ventricular fibrillation
C. Atrial fibrillation
D. Asystole
11. While caring for a client who has sustained an MI, the nurse notes eight PVCs in one minute on the
cardiac monitor. The client is receiving an IV infusion of D5W and oxygen at 2 L/minute. The nurse’s
first course of action should be to:
A. Increase the IV infusion rate.
B. Notify the physician promptly.
C. Increase the oxygen concentration.
D. Administer a prescribed analgesic.
12. The adaptations of a client with complete heart block would most likely include:
A. Nausea and vertigo
B. Flushing and slurred speech
C. Cephalalgia and blurred vision
D. Syncope and slow ventricular rate
13. A client with a bundle branch block is on a cardiac monitor. The nurse should expect to observe:
A. Sagging ST segments.
B. Absence of P wave configurations.
C. Inverted T waves following each QRS complex.
D. Widening of QRS complexes to 0.12 second or greater.
, 14. When ventricular fibrillation occurs in a CCU, the first person reaching the client should:
A. Administer oxygen.
B. Defibrillate the client.
C. Initiate CPR.
D. Administer sodium bicarbonate intravenously.
15. What criteria should the nurse use to determine normal sinus rhythm for a client on a cardiac monitor?
Select all that apply.
A. The RR intervals are relatively consistent.
B. One P wave precedes each QRS complex.
C. Four to eight complexes occur in a 6-second strip.
D. The ST segment is higher than the PR interval.
E. The QRS complex ranges from 0.12 to 0.20 second.
16. When auscultating the apical pulse of a client who has atrial fibrillation, the nurse would expect to hear
a rhythm that is characterized by:
A. The presence of occasional coupled beats.
B. Long pauses in an otherwise regular rhythm.
C. A continuous and totally unpredictable irregularity.
D. Slow but strong and regular beats.
17. Atherosclerosis impedes coronary blood flow by which of the following mechanisms?
A. Plaques obstruct the vein.
B. Plaques obstruct the artery.
C. Blood clots form outside the vessel wall.
D. Hardened vessels dilate to allow blood to flow through.
18. A paradoxical pulse occurs in a client who had a coronary artery bypass graft (CABG) surgery two (2)
days ago. Which of the following surgical complications should the nurse suspect?
A. Left-sided heart failure
B. Aortic regurgitation
C. Complete heart block
D. Pericardial tamponade
19. After cardiac surgery, a client’s blood pressure measures 126/80. The nurse determines that the mean
arterial pressure (MAP) is which of the following?
A. 46 mm Hg
B. 80 mm Hg
C. 95 mm Hg
D. 90 mm Hg
20. A woman with severe mitral stenosis and mitral regurgitation has a pulmonary artery catheter inserted.
The physician orders pulmonary artery pressure monitoring, including pulmonary capillary wedge
pressures. The purpose of this is to help assess the:
A. Degree of coronary artery stenosis.
B. Peripheral arterial pressure.
C. Pressure from fluid within the left ventricle.
D. Oxygen and carbon dioxide concentration is the blood.
21. The nurse is preparing to teach a client with microcytic hypochromic anemia about the diet to follow
after discharge. Which of the following foods should be included in the diet?
