Self-Study Module: Medication Drug Calculations

Despite all recent advances in medication administration, drug-related adverse events and error rates remain a concern. Many medication errors are related to administering incorrect dosages.

Medication administration must be performed in accordance with legislation, regulatory standards, CLPNA policies, and employer policies. Licensed Practical Nurses are responsible to ensure they possess the required knowledge, skill, and judgment to administer medications safely and competently. 

Often calculations are required prior to medication administration. Drug calculations can be simple or complex. Regardless of the drug to be administered, careful and accurate calculations are necessary to assist in preventing medication errors. Practicing calculations can enhance confidence and accuracy with medication calculation.
