Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Objective:

to assess the knowledge of scholars on Nursing regarding simple hands hygiene (SHH), blood pressure measurement (BP), peripheral venipuncture (PV) with venous catheter and male urethral catheterization delay (UCD) procedures.

Method:

quantitative study carried out between February and May 2014, with 186 undergraduate Nursing students from 5^th to 9^th period of a public university of Rio Grande do Norte, with application of four questionnaires. One carried out descriptive and analytic analysis.

Results:

the students presented low average percentage of right answers, especially in blood pressure measurement (55.5%); SHH's average was higher than 70%. The average of correct answers was the highest in SHH (8.6), followed by UCD (7.8), PV (7.4) and BP (6.7). The questions regarding the topic "concepts" showed less correct answers when comparing it to the topic "technique steps".

Conclusion:

it is necessary to establish knowledge monitoring strategies, in order to stimulate the constant improvement.
