The nurse is caring for a patient who has had an acute MI. The patient is receiving lidocaine IV. What is the most relevant factor to administration of this medication?
A) Decrease in arterial oxygen saturation (SaO2) when measured with a pulse oximeter
B) Increase in systemic blood pressure
C) Presence of premature ventricular contractions (PVCs) on cardiac monitor
D) Increase in intracranial pressure (ICP)
Ans: C
Feedback: Lidocaine (xylocaine) may be used in the patient with acute MI. Patients with acute MI who did not receive thrombolytics and had more than 10 PVCs per hour and those who did receive thrombolytics and had more than 25 PVCS per hour were found to be at the greatest risk for sudden cardiac death. SaO2, blood pressure, and ICP are important factors but aren't as significant as PVCs in this situation.
