Student nurses' knowledge in relation to blood pressure measurement by sphygmomanometry and auscultation.

A 20-item questionnaire was used to explore student nurses' knowledge in several areas of blood pressure measurement by sphygmomanometry and auscultation. Questions were asked about factors that might influence blood pressure; on resting the subject before BP measurement; which arm should be used; the interval between repeat readings; the markings of the mercury column; on the details of sphygmomanometry technique and recording of the result. The questionnaire was administered to a group of Project 2000 students nearing the end of their common foundation programme. Out of 93 students, 78 consented to take part, representing 84% of the cohort. Deficits were evident in students' background knowledge-90% had not heard of either Korotkoff sounds or auscultatory gap. Major deficits were also evident in the students' knowledge of correct measurement techniques. The results suggest that more attention is required in preparing students to carry out this basic nursing activity.
