Hello, I am a RN of almost 2 years in January. I currently work on a Cardiac Telemetry Floor/Intermediate care unit, so i work with different drips: nitro, dopamine, primacor, dobutamine, etc. During my internship I feel as if i wasn't really oriented the way i should have but i realize it is up to me to gain the knowledge that is needed bc this is my license on the line. Does any one know of any books that help with explaining cardiac medications, what when and how they are used in easy to comprehend language? I am trying to get a really good knowledge base of the basics and grow from there? How about any really good cardiac books explaining how these medications act on the heart, any suggestions will be greatly appreciated!
