The goal of this randomized controlled study is to assess the effect of guided imagery on chemotherapy-related nausea and vomiting in pediatric oncology patients.

Participants will receive either guided imagery+routine care or routine care. The researchers will compare nausea and vomiting and vital signs between groups.

Despite significant advances in anti-emetic treatment, chemotherapy induced nausea and vomiting (CINV) is considered a major side-effect that significantly reduces the quality of life of children diagnosed with cancer. Guided imagery is one of the methods of distraction that allows the individual to go to an environment or scene that will make the individual comfortable, peaceful, happy, and focused. In this study, the participants will be randomized in a single blind manner (participant) to either intervention or control groups.
