The relationship between nursing students' mathematics ability and their performance in a drug calculation test.

Nurses and nursing students need good mathematics skills to do drug calculations correctly. As part of their undergraduate education, Norwegian nursing students must take a drug calculation test, obtaining no errors in the results. In spite of drug calculation tests, many adverse events occur, leading to a focus on drug administration skills both during students' courses and afterwards. Adverse events in drug administration can be related to poor mathematics skills education. The purpose of this study was to investigate the relationship between students' mathematics experiences in school (primary, secondary and high school) and their beliefs about being able to master the drug calculation test. A questionnaire was given to 116 first-year Bachelor of Nursing students. Those students who assessed their mathematics knowledge as poor found the requirement to obtain no errors in the drug calculation test more stressful than students who judged their mathematics knowledge as good. The youngest students were most likely to find the test requirement stressful. Teachers in high school had the most positive influence on mathematics interest, followed by teachers in secondary and primary school.
