Objective: to analyze the effectiveness of an educational intervention on knowledge related to pressure injuries among nursing students. Methods: a quasi-experimental study with a before-and-after design. Participants completed the following stages: assessment of prior knowledge, educational intervention, and post-intervention reassessment. The final sample consisted of 30 students. A validated instrument was used to measure knowledge about pressure injuries. The analysis included comparisons between time points, the McNemar test for item-by-item evaluation, and calculation of effect size. Results: before the intervention, only 20 items presented a percentage of correct answers considered satisfactory, increasing to 38 items after the intervention. Statistically significant changes (p<0.05) were observed in 16 items, as well as a significant increase in the mean number of correct answers and a reduction in errors post-intervention, with a large effect size (r = 0.874), indicating a robust educational impact. Conclusion: the educational intervention was effective in increasing nursing students’ knowledge. Contributions to practice: the findings support the adoption of well-planned and well-executed educational interventions as a strategy to improve nursing education, strengthening competencies essential to patient safety and quality of care.
