Nursing pharmacology is a class that nurses are required to take before they receive their licenses. The course teaches nurses how various drugs interact in a patient's body and allows these professionals to administer drugs and educate patients on their medications. Nurses can gain an understanding of the medications that they must use on their patients as they are healing. They can use their knowledge to discuss side effects that certain drugs have and make suggestions on how patients can minimize them. Nurses also learn about the toxicity of drugs and may suggest adjustments when drugs are causing a negative reaction in patients.
