Preschool period is a crucial stage of life in terms of a child's physical, intellectual, emotional, and social development, health promotion knowledge of pre-school caregivers is an important factor that affects children's health. Nursery school is essentially an important place for preschool children to learn healthy eating, adequate hydration, exercise, proper hygiene, teeth care, and controlling emotions with their classmates. Caregivers as educators should make preschool children aware of the dangers of unhealthy behaviors which cause fall, burn, bleeding, and airway obstruction.

Aimed of the present study was to determine the effect of health promotion guidelines on knowledge and practice of caregivers at nursery schools. Convenience sample caregivers contacted by children from 3-6years working at 20 nurseries. The total number of sample was 60 caregivers. Tools of data collection included A structured interview questionnaire & observational checklist and health promotion guidelines to assess Caregivers' knowledge and practice about health promotion of preschool children. Results: There were statistically significant differences in relation to knowledge and practice scores of the caregivers throughout the three phases of the guidelines intervention. Conclusion, it was concluded that guidelines effect on caregivers' knowledge and practice regarding health promotion of preschool children. Recommendation of this study was to provision of health guidelines for caregivers especially those new about health promotion and the needs of preschool children.

Background: Iatrogenic events that cause harm to neonates in NICU is characterized as adverse events. Neonates are a particularly vulnerable population and may be at further risk of harm from medical errors because of their low birth weight, physiological immature, limited compensatory abilities and extensive exposure to medication in NICU. Nurses are the first line of defense to safeguard against iatrogenic errors. Aim of this study was to evaluated the effect of educational intervention program on nurses' performance and clinical outcomes of neonates related to nurses' iatrogenic at neonatal intensive care unit. Subjects and method The study was conducted at Neonatal Intensive Care Unit of Tanta University hospital. A quasi-experimental design was used. Sample All nurses (57) working in the previously mentioned setting were included the study and all neonates admitted within six months. Tools: Three tools were used to collect the required data; Structured Interview schedule, It was consisted of two parts, part one was biosocial data of nurses, neonate and part two was nurses' knowledge (tool I). Observation checklist to assess nurse's practice regarding iatrogenic errors at NICU (tool II). Neonate's clinical outcomes schedule to assess outcomes of neonate post program (tool III). Results of the study revealed that, before program the total knowledge scores of all nurses were poor while majority of them had good scores after implementing program. Total practice scores of all nurses were good also immediately and after one month. There were statistical significant difference between nursing knowledge, practice and biosocial data. The outcome of neonates showed an improvement in neonatal condition of discharge. Conclusion Intervention program was effective and improving nurses' knowledge and practice as well as reducing iatrogenic errors at NICU. Recommendations were suggested that establish continuous monitoring system to assess nurses practice in NICU settings especially for iatrogenic errors.
