Which of the following medications is NOT considered critical care?

Lidocaine is frequently used for the management of certain arrhythmias, particularly ventricular arrhythmias, but it is not classified as a critical care medication. Critical care medications typically refer to those that are essential for the immediate stabilization of patients in life-threatening situations, such as epinephrine for anaphylaxis or cardiac arrest, norepinephrine for severe hypotension and shock, and adenosine for acute supraventricular tachycardia. These medications are integral in emergency and critical care settings due to their roles in rapidly reversing life-threatening conditions.

In contrast, lidocaine's use is often in less acute settings or as part of a routine treatment protocol, rather than being a primary agent for immediate resuscitation or stabilization in critical situations. Thus, its absence from the critical care category reflects its more targeted and situational use compared to the other agents listed.
