Improving medication calculation skills of practicing nurses and senior nursing students: a pilot study.

Medication administration is an essential nursing competency as calculation difficulties can lead to serious medication errors. Nurses involved in staff education need to be aware of methods to assess for computation difficulty and develop strategies for nurses to improve their computation abilities. The purposes of this quasi-experimental pilot study were to assess the medication calculation skills of nurses and nursing students and to determine the effectiveness of teaching strategies aimed at improving these skills.
