Final answer:
It is true that a medical assistant needs to understand the category and primary use of drugs to follow physician orders, as this enables them to handle medications safely and inform patients appropriately.
Step-by-step explanation:
As a medical professional, it is true that a medical assistant needs to know the category and primary use of a particular drug in order to follow the physician's orders correctly. This knowledge is essential to understand the intended effects of the medication, to recognize its potential side effects, and to educate the patient about the medication they are receiving. Additionally, understanding the class of a drug, such as whether Prozac is a psychoactive drug (which it is, as it is classified as an antidepressant), helps the assistant in managing and understanding the treatment plan. It is also true that anxiolytics, which are prescribed to alleviate anxiety, may be directly related to drugs that affect GABA receptors and usually have a depressant effect because of their impact on slowing down brain activity.
