Question 1 of 5
A nurse in a coronary care unit is admitting a client who has had CPR following a cardiac arrest. The client is receiving lidocaine IV at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
Correct Answer: A
Rationale: The correct answer is A: Prevents dysrhythmias. Lidocaine is a class Ib antiarrhythmic medication commonly used to treat and prevent ventricular dysrhythmias. It works by stabilizing the cardiac cell membrane and reducing the automaticity of the ventricular muscle, thus preventing abnormal heart rhythms. The other choices are incorrect because lidocaine does not dissolve blood clots (
B), slow intestinal motility (
C), or relieve pain (
D). It is important for the nurse to educate the client on the purpose of the medication to ensure understanding and compliance with the treatment plan.
