  METHODS
  quantitative study carried out between February and May 2014, with 186 undergraduate Nursing students from 5th to 9th 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".
