Effect of left- or right-handedness on nursing practice.

The aim of the present study was to evaluate the association of hand preference of nursing and the success of the nursing practice. The study included 24 students, all of whom attend different classes in the School of Nursing. The status of left- or right-handedness of the students included in the research was determined using Oldfield (Edinburgh Handedness Inventory) Index. The students were divided into two equal groups according to their right or left hand use. Then the students were categorized in four groups (Very good: 81-100, Average: 61-80, Pass: 50-60, and Fail: <50) according to the scores they received from the practice and theory tests of the lesson "Fundamentals of Nursing" the lesson requiring hand skills most. The test for the difference between two population proportions was used for statistical analysis. Left-handed nurses were found to be more successful than right-handed nurses in nursing practice. The difference between them was found significant (p < .01). It was concluded that left-handed nurses should never be forced to convert into right-handedness; instead they should be supported both verbally and in terms of equipment, and they should be motivated, because the data obtained proved that left-handedness means success.
