Research Interest:
Background: Accurate and secure medication calculation is critical in nursing care, as errors can lead to serious adverse events. Identifying effective methods to enhance medication dosage calculation skills during nursing education is essential.
Aim: This study examined the impact of incorporating visual images of medications or syringes into drug dosage calculation exams on nursing students’ performance, perceived ease of learning (EOL), and calculation precision. Methods: In this prospective comparative study, 120 nursing students were randomly assigned to either a control group (no images) or a study group (with images embedded in the exam). A validated questionnaire, including demographics, EOL assessment, and calculation questions, was administered. Three outcome measures were compared between groups: test performance, EOL level, and precision of calculations.
Results: The study group (with images) scored significantly higher on the exam (mean = 7.25, SD = 1.80) compared to the control group (mean = 6.00, SD = 1.18). The EOL was also significantly higher in the image group (mean = 87.71, SD = 14.41) than in the control group (mean = 73.37, SD = 15.31), suggesting that visual aids improved comprehension and perceived exam ease. BSN track students outperformed those in the academic retraining track (7.03 vs. 6.20, p < 0.01). The calibration index showed significant differences only in two questions (2 and 7), indicating limited influence of images on overall judgment accuracy.
Conclusions: Incorporating images into dosage calculation exams significantly improves students’ performance and perceived ease of learning, suggesting a 15% performance increase. However, the effect on calculation precision across all questions was limited. Visual tools may be a valuable strategy for enhancing drug calculation proficiency in nursing education.
