Quiz: Anesthesia Pharmacology Exam! - Quiz

Anaesthesia pharmacology exam! Different drugs exhibit different results on a patient, and this is why nurses need to evaluate a patient's vitals and reaction to various drugs and analyze whether the differences are acceptable or not. How conversant are you with gases when it comes to anaesthesia? This quiz will help refresh your memory on some techniques and knowledge you should have as an anaesthetist. Check it out!
