As a nursing student, pharmacology will help you understand how drug actions affect biological systems within the human body. This study guide has been designed to help nursing students master the commonly encountered and commonly tested topics associated with antibiotic use, and how you will use them to treat your patients. These include the high-yield concepts such antibiotic indications, mechanism of action, contraindications, routes of administration, side effects, nursing considerations, and more, giving you the exam prep boost you need to dominate your classes and the NCLEX®.
