The effect of audio-visual video with korotkoff sounds on anxiety levels and blood pressure measurement skills of nursing students: A randomized controlled study

Aim: This study was aimed to determine the effect of the audio-visual video created with korotkoff sounds on the anxiety levels and blood pressure measurement skills of nursing students.Background: Blood pressure measurement is the basis of nursing care and clinical decision. For this reason, it is stated that nursing students should specialize in this skill.Design: This research was conducted as a randomized controlled experimental study.Method: This research was conducted with 130 (intervention group: 67, control group: 63) nursing students in the nursing department of a university in March 2022. Before the skill practice, the students in the intervention group listened to the korotkoff sounds using an audio-visual video containing the korotkoff sounds and then the practice was made. Data of the study were collected using the short version of the State-Trait Anxiety Inventory, the student introduction form and the blood pressure measurement evaluation form.Results: The mean age of the students was 19.41 (SD 1.75) in the intervention group and 19.20 (SD 1.04) in the control group. The State-Trait Anxiety Inventory mean scores of both groups were similar before the skill practice. At the end of the skill practice, the state anxiety score of the intervention group 0.56 (SD 1.03) was lower than the control group 1.30 (SD 1.81) and the difference was statistically significant (p < 0.05). When the blood pressure measurements of the students in both groups were compared, the rate of hearing korotkoff sounds and measuring blood pressure correctly was higher in the students in the intervention group and the difference was statistically significant (p < 0.05).Conclusion: The korotkoff sounds presented with audio-visual video increased the skill levels of the students and reduced the anxiety level. In this direction; it is recommended to use audio-visual video containing korotkoff sounds for students to gain blood pressure measurement skills.
