Common double-lumen tube selection methods overestimate adequate tube sizes in individual patients - a 3D reconstruction study.

Background: Appropriate selection of double-lumen tube sizes for one-lung ventilation is crucial to prevent airway damage. Current selection methods rely on demographic factors or 2D radiography. Prediction of left bronchial diameter is indispensable for choosing the adequate tube size.

Understanding nurse practitioner autonomy.

Purpose: This Gadamerian hermeneutic study was undertaken to understand the meaning of autonomy as interpreted by nurse practitioners (NPs) through their lived experiences of everyday practice in primary health care.

Data Sources: A purposive sample of nine NPs practicing in primary health care was used. Network sampling achieved a broad swath of primary care NPs and practice settings.

Integrating spirituality into critical care: an APN perspective using Roy's adaptation model.

Integration of the spiritual domain into the nursing plan of care positively influences health and wellness. Applying nursing theory to practice reinforces the advanced practice nurse's (APN's) responsibility to integrate spiritual care into the critical care environment. Indeed, all nurses have an obligation to integrate spiritual care because the focus of nursing care is beneficence.

Reflections on independence in nurse practitioner practice.

Purpose: To examine factors that influence the ability of nurse practitioners (NPs) to practice as independent primary care providers.

Data Sources: Extensive literature search on CINAHL, OVID, MEDLINE, Internet journal sources, and professional association Web sites.

Conclusions: The legal authority for NPs to practice independently is recognized; however, the ability to put that authority into practice is undermined by the historical failure of political, professional, and social entities to recognize NPs as providers capable of providing primary care autonomously.
