Start chest compressions of at least 100 per min. You are evaluating a 58 year old man with chest pain. The BP is 92/50 and a heart rate of 92/min, non-labored respiratory rate is 14 breaths/min and the pulse O2 is 97%. What assessment step is most important now? Obtaining a 12 lead ECG. Identification of Chest Discomfort Suggestive o...

4TH SEMESTER URDEN 1. Which of the following structures is the primary pacemaker of the heart? a. Ventricular tissue c. Sinoatrial node b. Atrioventricular node d. Purkinje fibers ANS: C With an intrinsic rate of 60 to 100 beats/min, the sinoatrial node is the primary pacemaker in a healthy heart. The atrioventricular node beats 40 to 60 beats/min. Ventricular tissue must have an electrical impulse to contract. Purkinje fibers beat 15 to 40 beats/min. 2. The atrioventricular (AV) nod...

MEDSURG 2 FINAL EXAM. Medsurg 2 FINAL EXAM Cardiac Assessment Cardiac Conduction System ⦁ Generates and transmits electrical impulses that stimulate contraction of the myocardium ⦁ SA node  AV node  Bundle of his (branches into right and left)  purkinjie fibers ⦁ SA node which is the primary pacemaker of the heart ⦁ A patient has a HR of 90. Means The SA node is working because normal HR is 60-100 ⦁ If the HR falls below the normal value, there is a problem! ⦁ AV ...

NURS 621 MEd Challenger Cardio Exam Questions VALVULAR HEART DISEASE 1) A 71-year-old woman with chronic aortic regurgitation complains of worsening dyspnea on exertion, orthopnea, fatigue, and angina. She is anxious because of an unpleasant awareness of her heartbeat. Her cardiac silhouette is enlarged, with uncoiling and enlargement of the aortic root seen on chest x-ray. She has a widened pulse pressure, rapidly rising and falling carotid pulse, spontaneous nail-bed pulsations, and a ...
