EFFECT OF THE ASSOCIATION OF TWO EDUCATIONAL INTERVENTIONS ON STUDENTS’ KNOWLEDGE ABOUT HYPODERMOCLYSIS: A QUASI-EXPERIMENTAL STUDY

Abstract

ABSTRACT Objective: to ass the effect of associating the problematization methodology with practical demonstration on nursing students’ knowledge about hypodermoclysis. Method: this is a quasi-experimental study with 20 students in their final year of the undergraduate course in nursing at a public higher education institution, located in Viçosa, Minas Gerais, Brazil. Students participated in two educational interventions focused on teaching hypodermoclysis, one using problematization methodology and the other the practical demonstration of the puncture technique. The effect of the interventions on students’ knowledge was assessed using a previously validated questionnaire applied before the first intervention and after the second intervention. The results were compared using the McNemar test. Results: students’ mean age was 24.7 (±1.7) years, with a predominance of females (75.0%). It was found that, of the 12 questions assessed about theoretical and practical knowledge of hypodermoclysis, 10 (83.3%) showed an increase in correct answers after educational interventions (p<0.05). Students’ mean score in self-assessment on their ability to explain the procedure (before: 0.9 points; after: 7.7 points) and perform the technique (before: 2.1 points; after: 8.1 points) was significantly higher after educational interventions (p<0.001). Conclusion: the number of correct answers by nursing students on theoretical and practical questions about hypodermoclysis and self-assessment was greater after participating in educational interventions, which demonstrates a positive effect of the association of problematization methodology and practical demonstration as a teaching strategy on this topic.
