I remember being taught in school that after an MI if the pt has PVC it could result in ventricular tachycardia. This is why I chose this answer, but now I'm second guessing my knowledge. Am I right in my thinking or perhaps not remembering things right.
The client in normal sinus rhythm with a peaked t wave.-a. (correct) a client with a peaked wave could be experiencing hyperkalemia. changes in potassium levels can initiate cardiac dysrhythmias and instability.b. (incorrect) fluctuations in rate are expected in clients diagnosed with atrial fibrillation, and a heart rate of 100 is at the edge of a normal rate.c. (incorrect) most people experience an occasional premature ventricular contraction (pvc); this would not warrant the nurse assessing this client first.d. (incorrect) a first-degree block is not an immediate problem.test-taking hint: the test taker must know the normal data so that the abnormal will be apparent. normal heart rate is 60-100. the nurse should assess the client who has an abnormal or life-threatening condition.
