The literature shows that providing patient education before surgery reduces stress. Fernandes, Arriaga, and Esteves (2015) tested the impact of a multimedia educational intervention on the cognitive, emotional, and physiological responses of children undergoing surgery. The study was conducted on children assigned to three different groups: a multimedia educational intervention (experimental group), an intervention with entertainment video games (comparison group) and a control group (no intervention). Children who received the multimedia educational intervention reported a lower level of stress related to hospitalization, medical procedures, illness, and negative consequences compared to those in the control and comparison groups (Fernandes, Arriaga, & Esteves, 2015). Their findings suggested that providing information to children and parents about medical procedures, hospital rules and routines reduced preoperative stress or worries. One of the limitations of this study was the small sample size and sampling was limited to children of various ages. The validity of the research material was supported by reliable studies, random samples were used when possible and systematic errors were avoided. The overall findings supported the beneficial aspects of providing preventative patient education
