1) 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 2) 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. 3) 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. 4) 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 5) 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 6) 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 7) The adaptations of a client with complete heart block would most likely include: a) Nausea and vertigo b) Flushing and slurred speech c) headache and blurred vision d) Syncope and slow ventricular rate 8) When ventricular fibrillation occurs in a ED, the first person reaching the client should a) Administer oxygen. b) Defibrillate the client. c) Initiate CPR. d) Administer sodium bicarbonate intravenously. 9) 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. 10) 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.
