4 | Page C. Ventricular tachycardia D. Premature ventricular contractions 46. The patient soon stabilized. However, after administration of a drug, the client has frequent bursts of ventricular tachycardia on the cardiac monitor. What should the nurse be most concerned about with this dysrhythmia? A. It can develop into ventricular fibrillation at any time. B. It is almost impossible to convert to a normal rhythm. C. It is uncomfortable for the client, giving a sense of impending doom. D. It produces a high cardiac output that quickly leads to cerebral and myocardial ischemia. 47. Marinelle, who is receiving digitalis, is having frequent premature ventricular contractions. A nurse would place priority on assessment of which of the following? A. Sensation of palpitations B. Causative factors, such as caffeine C. Precipitating factors, such as infection D. Blood pressure and oxygen saturation 48. Jen is a patient who was admitted for thyrotoxicosis. She has developed atrial fibrillation, with a ventricular rate of 153 beats/ min. The nurse should assess the client for which associated signs or symptoms? A. Flat neck veins B. Nausea and vomiting C. Hypotension and dizziness D. Hypertension and headache 49. Amari has been diagnosed with Brugada Syndrome. Nurse Tere has been monitoring Amari’s ECG. There are no P waves; instead, there are fibrillatory waves before each QRS complex. How should the nurse correctly interpret the client’s heart rhythm? A. Atrial fibrillation B. Sinus tachycardia C. Ventricular fibrillation D. Ventricular tachycardia 50. Nurse Venice is monitoring a patient with severe hypokalemia. At first, the patient developed premature ventricular complexes until the patient 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. 51. Nurse Rene is caring for an acidotic patient 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. 52. Petra C is currently experiencing atrial fibrillation. The SO 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. 53. Nurse Marian is currently monitoring a critically ill patient. She notes that although the client has a sinus rhythm, he has 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 54. Protacio S ws admitted to the Central ICU due to a posterior wall myocardial infarction. Nurse Fiona had been monitoring his ECG tracing and 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. 55. Teresita was diagnosed with complete heart block and is currently undergoing pacemaker insertion. Which of the following adaptations would you expect to see in her patient history? A. Nausea and vertigo B. Flushing and slurred speech C. Cephalalgia and blurred vision D. Syncope and slow ventricular rate 56. Gerry X has a right sided heart failure and is currently being monitored for a bundle branch block. The nurse should monitor 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. 57. Nurse Coleen is currently 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. 58. Lola Flora came to the clinic today for a regular check-up. It was found out that she has a high cholesterol in the blood. The physician informed her of being at risk for atherosclerosis which can prevent 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. 59. Martin has undergone a coronary artery bypass graft surgery. The nurse monitors his blood pressure and observed that patient's during inspiration his blood pressure falls to greater than 10 mm Hg. 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 60. 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 61. Celine came to the clinic with fever, cough, and colds. No history of cardiovascular disease. However her chest pain prompted her to consult. Which of the following questions would best help a nurse to discriminate pain caused by a non- cardiac problem? A. "Have you ever had this pain before?" B. "Can you describe the pain to me?" C. "Does the pain get worse when you breathe in?" D. "Can you rate the pain on a scale of 1-10, with ten (10) being the worst?" 62. Lourdes, a patient with anterior wall myocardial infarction has been transferred from a coronary care unit to a general medical unit with cardiac monitoring. A nurse plans to allow for which of the following client activities? A. Strict bed rest for 24 hours after transfer. B. Bathroom privileges and self-care activities. C. Unsupervised hallway ambulation with distances under 200 feet. D. Ad lib activities because the client is monitored. 63. Carmen is a patient with chronic heart failure. Upon assessment, a 2+ bilateral edema in the lower extremities of a client is present. The nurse would plan to do which of the following next?
