The nurse is caring for a 65-year-old male client with a history of
ischemic heart disease who has been admitted to the ICU
following a myocardial infarction. The client is currently receiving
lidocaine I.V. to manage his ventricular ectopy, which has been
persistent. Which of the following factors would be most
important for the nurse to consider in relation to the
administration of this medication?
o A. Decrease in arterial oxygen saturation (SaO2) when
measured with a pulse oximeter
o B. Increase in systemic blood pressure
o C. Presence of premature ventricular contractions
(PVCs) on a cardiac monitor
o D. Increase in intracranial pressure (ICP)
o E. A drop in serum potassium levels as indicated in the
latest lab results
o F. Observation of a widening QRS complex on the
ECG
Incorrect
Correct Answer: C. Presence of premature ventricular
contractions (PVCs) on a cardiac monitor.
In the context of acute myocardial infarction, the priority is to
manage life-threatening arrhythmias. Lidocaine is specifically
indicated for the treatment of ventricular arrhythmias, such as
PVCs, which can be indicative of an increased risk for more
serious arrhythmias like ventricular tachycardia or ventricular
fibrillation. The presence of PVCs on a cardiac monitor would be
the most immediate concern that lidocaine can address in this
scenario. While the other factors listed are important to monitor,
they are not the primary indications for lidocaine administration
in the context of arrhythmia management.
