The first step in the nursing precess is assessment of patients, their conditions and health problems. Objective data to be gethered include vital signs. Blood pressure is a basic nursing art students usually learn and apply early in clinical practice. Do they use the technique taught in the practice laboratory?. Do influences in the practice setting modify their technique? Does their technique affect the accuracy of their blood pressure measurement? This study investigated nursing students' technique in taking blood pressures of patients in the clinical setting.
The purpose was to contribute to the improvement of blood pressure measuring technique instruction and application in the clinical setting and thus the accuracy of one kind of objective data used in nursing assessment.
The sample consisted of the 76 first year and 64 second year students of a rural college of nursing in the Republic of Korea. The patients were from the various wards in two general hospitals where the students were assigned for functionally organized nursing care.
The investigator defined from the literature a list of 21 criteria with which the students' technique were compared by direct observation. Students were instructed to use the technique learned in the laboratory. Lacking a teaching stethoscope, the investigator, using the creteria, measured the patients' blood pressures. Results were analysed by discriptive statistics, mean, ratio, and a z test of significance.
Ommitting items on the criteria list not studied, of the remaining 14 criteria, average accuracy of first year students was 80 per cent, and of second year students, 74 per cent. Both years ranged from 7 to 13 points out of 14, with an average of 11.2 for first year, and 10.4 for second year students. The investigator hypothesized that with a longer period of influence from the clinical environment, second year students, according to field theory, would score less than first year students. This hypothesis was not supported statistically by a z test. A further hypothesis, that student score would be related to the accuracy of blood pressure readings, as recorded by the investigator, was abandoned because no statistically significant difference could be shown between the students' and investigator's measurements.
Although first year students' score were higher than second year students, second year students' reading were closer to the investigator's. Variables not measured may be influencing the accuracy of blood pressure measurement: first year students ahd problems with recognition of sounds and readings.
Recommendations were made related to student instruction, laboratory experience and in-serve education of nursing models in the clinical setting. Further research should explore the use of a teaching stethoscope, weighting of criteria, and the accurate measurement of other influencing variables, and the application of influential statistics.
