57.ID: 383720806A client who experiences frequent episodes of chest pain is admitted to the hospital for cardiac monitoring. The client suddenly complains of chest pain, and the nurse obtains a 12-lead electrocardiogram (ECG). Which of the following findings would the nurse expect to note in the event of an ischemic episode? Peaked T waves ST-segment depression Correct
Widened QRS complex An isolated premature ventricular contraction (PVC) Rationale: An ECG taken in the presence of pain may reveal ischemic changes with ST-segment elevation or depression. Peaked T waves may indicate hyperkalemia. PVCs are caused by the firing of an irritable pacemaker in the ventricle. A widened QRS complex indicates a delay in intraventricular conduction, such as bundle branch block.Test-Taking Strategy: Knowledge regarding the effects of ischemia on myocardial tissue and how it is reflected on an ECG is needed to answer this question. Remember that ST-segment elevation or depression indicates myocardial ischemia. Review the effects of myocardial ischemia if you had difficulty with this question.Reference: Ignatavicius, D., & Workman, M. (2010).
