Nurse Education and Mathematical Competency: Implementation of an Online, Self-Directed, Prerequisite Model.

Mathematical competency in the profession of nursing has increasingly become a central focus as more nursing students appear to struggle with basic concepts of arithmetic, mental estimation, and critical reasoning. This paper highlights how one School of Nursing in Ontario, Canada implemented a Dosage Calculation Competency Test model which involved an online, self-directed, prerequisite approach to improve student mathematical competency and confidence. The purpose of this research case study was to document, through shared participant perceptions, the creation, implementation, and subsequent modifications to a Dosage Calculation Competency Test model in light of student needs and advances in online learning and assessment.

Implications of Clinical Shift Length on Nursing Student Learning Outcomes.

Background: One area of clinical education that requires further understanding is the role clinical shift lengths play in nursing student learning outcomes.

Method: This study used a mixed-methods design. Collaborative nursing students were randomly placed into clinical groups.

The dose-dependent effects of chronic iron overload on the production of oxygen free radicals and vitamin E concentrations in the liver of a murine model.

Genetic disorders of iron metabolism such as primary and secondary hemochromatosis affect thousands of individuals worldwide and are major causes of liver dysfunction, morbidity, and mortality. Although the exact mechanism of hepatic injury associated with these genetic disorders is not fully understood, the propagation of excess concentrations of iron-catalyzed oxygen free radicals (OFRs) may play a role. The authors hypothesized that chronic iron burden would result in dose-dependent (a) increases in hepatic iron stores, (b) increases in hepatic OFR-mediated hepatic cellular injury as quantified by the cytotoxic aldehydes malondialdehyde (MDA) and hexanal, and (c) decreases in protective antioxidant reserve status as quantified by plasma vitamin E (alpha-tocopherol) levels in a murine model.
