Medication errors occur throughout health care settings. These errors can be caused by a multitude of factors, one of the most important being mathematical calculation. The purpose of this study was to replicate an earlier study by Bindler and Bayne (1991) examining the mathematical calculation ability of registered nurses. Utilizing a model of skill acquisition suggested by Dreyfus and Dreyfus (1980) and applied to nursing by Benner (1986), it was hypothesized that years of experience and frequency of calculation would have a significant interactive effect on the score of a medication calculation test.; A descriptive correlational design was utilized. A convenience sample of registered nurses (n = 92) was tested. The hypothesis was not supported as being statistically significant.
