Fundamentals of Nursing: drug classifications Exam #1 Questions
with Correct Answers
Drug Classifications- 20 questions on this chapter
Know drug classifications, examples of each, mechanism of action and nursing
implications.
For the test, you will be given both the generic and trade name.
Example: metoprolol (Lopressor) 25 mg PO daily, is a beta blocker which is used
to lower a patient's BP and heart rate. Nursing implication would be to check the
patient's BP and HR prior to giving it. The critical thinking is what to do with that
information. You check the patient's HR and it is 48 and the BP is 110/68. Normal
HR is 60-100 so the patient's HR is very low. BP is ok. What's going to happen to
the patient if you give this medication? The HR will drop even more and the
patient could medically crash. The nursing implication would then be to hold the
medication and notify the healthcare provider if indicated. - ✔✔A drug may be
classified by the chemical type of the active ingredient or by the way it is used to
