Inventory of ethical problems in mobile pre-hospital care.

Objective: to construct and validate the content of an inventory of ethical problems experienced by nurses in mobile pre-hospital care.

Method: a psychometric approach study, developed with the following stages: (1) instrument construction through a theoretical matrix based on deliberative bioethics, scoping review and online qualitative research; (2) content validity by judges; (3) pre-testing with Mobile Emergency Care Service nurses in various Brazilian states. For content validity analysis, the Content Validity Ratio was calculated (CVR>0.

Effects of instructional therapeutic play in the behavior of children during the first attempt at intravenous catheterization.

Objective: To verify the effects of instructional therapeutic play on the behavior of children during the first attempt at peripheral intravenous catheterization.
