Question 1 of 5
In the client with a diagnosis of coronary artery disease, the nurse would anticipate the complication of bradycardia with occlusion of which coronary artery?
Correct Answer: A
Rationale: Sinus bradycardia and atrioventricular (AV) heart block are usually a result of right coronary artery occlusion. The right coronary artery perfuses the sinoatrial and AV nodes in most individuals. Occlusion of the left main coronary artery causes bundle branch blocks and premature ventricular contractions. Occlusion of the circumflex artery does not cause bradycardia. Sinus tachycardia occurs primarily with left anterior descending coronary artery occlusion because this form of occlusion impairs left ventricular function.
