The usage of medications is greatly influenced by nurses. It is crucial for them to understand the Mechanism of Actions, Indications, Contraindication/Precaution, Adverse Effects and Interactions of drug dispensed as well as Nursing Responsibilities because it is they who are responsible for administering the drug, observing the patient's acceptance of the drug, and noting any untoward reactions to the drug. This book was written with nurses' needs for pharmacological expertise in mind.
