pediatric hospitalization, the confinement of a child or infant in a hospital for diagnostic testing or therapeutic treatment. Regardless of age or the degree of illness or injury, hospitalization constitutes a major crisis in the life of a child, and the emotional trauma may elicit various behavioral reactions that the nurse must recognize and be prepared to cope with to facilitate recovery. The dominant factors influencing stress, which vary according to the child’s developmental age, his or her previous experience with illness, and the seriousness of the condition, include separation from the parents and familiar environment, disruption of routine patterns of daily life, loss of independence, and worry about bodily injury or painful experiences. The nurse can minimize stress by preparing the child and family through prehospital counseling; by encouraging active parental participation in the child’s care through rooming-in facilities or frequent visits; by maintaining as normal a daily routine as possible, especially with eating, sleeping, hygiene, and play activities; by explaining all hospital procedures and the immediate and long-term prognosis in terms that the child can easily understand; and by providing support and guidance for parents and siblings. Child life specialists can also be extremely helpful in teaching coping strategies to children and families during a hospitalization. The nurse also may use the hospital experience to foster an improved parent-child relationship and to teach other members of the family about proper health care. Emergency admission greatly increases the emotional trauma of hospitalization, making the nurse’s role in counteracting negative reactions even more significant.
