This self-instructional guide is designed for the nurse who works primarily in an adult patient setting but occasionally cares for a pediatric client. Although proficient in nursing skills, this nurse might experience anxiety when assigned a pediatric client. It is hoped that having this information will replace anxiety with confidence. 相似文献

The current model for delivery of prenatal care was developed more than 100 years ago. Evidence suggests that this model is no longer appropriate for meeting national health objectives or for meeting the needs of a diverse population of pregnant women. This article provides a historical overview of prenatal care; describes the current system for care delivery and problems associated with it; and suggests strategies for transforming care into an effective, comprehensive model.

An Australian school of nursing's attempt to introduce an evaluation process required by management for clinical educators involved in undergraduate preregistration education is discussed Reliance on student feedback and clinical agencies' perceptions of the quality of teaching were seen as inadequate mechanisms for evaluation The evaluation process adopted incorporated observation of the educators together with self-reflection on their performance We conclude that post-briefings were poorly used and generally not reflective Educators relied heavily on their clinical skills and used a limited range of teaching strategies Whilst evaluation of clinical educators was time consuming and therefore costly, it is argued that it is essential to the integrity of the course The evaluation process has provided direction for support and development of clinical educators within the context of the curriculum 相似文献

Objective: To describe a model for providing breastfeeding support in the neonatal intensive-care unit (NICU).
Design: Naturalistic, participant observation.
Setting: Suburban Level III NICU.
Patients: One hundred thirty-two mother-infant pairs over 1 year. Infants were hospitalized In the NICU, and mothers had initiated lactation efforts.
Interventions: Investigators provided breastfeeding interventions for the mother-infant pairs, based on identified problems, the research literature, or both.
Main Outcome Measures: Percentage of mothers who were breastfeeding at the time of discharge from the NICU.
Results: Interventions were classified into jive categories: expression and collection of mothers' milk, gavage feeding of expressed mothers' milk, in-hospital breastfeeding sessions, postdischarge breastfeeding management, and additional consultation.
Conclusions: This model was effective In preventing breastfeeding failure for this population. The model can provide the basis for NICU breastfeeding standards of care, protocols, and chart records, or for reimbursement purposes. The model also provides a framework for studying a specific category or breastfeeding intervention. 相似文献
