This study aimed to apply the WHO surgical safety checklist in the surgical specialties of a university hospital and to evaluate the opinion of the team regarding the influence of its application on the safety of the surgical process and on the interpersonal communication of the team. It is a descriptive, analytical qualitative field study conducted in the surgical center of a university hospital Data were collected by applying the checklist in a total of 30 surgeries. The researcher conducted its application in three phases, and then members of the surgical team were invited to voluntarily participate in the study, signifying their agreement to participate by signing an informed consent form and answering guiding questions. Bardin's Content Analysis Method was used to organize and analyze the data. The subjects did not notice any changes in their interpersonal communication when using the checklist; however, they gave suggestions and reported that its use provided greater safety to the procedure.

Objective: to report the experience of the development of nursing knowledge from nursing theories and points of contact with the nurse’s praxis.

The students presented seminars approaching the main nursing theories, generating extensive discussion and correlating them with the nurse’s practice. Review and reflection on the contents addressed. Result: two themes were defined: the training of nursing undergraduate students and the development of knowledge in relation to the concepts of nursing theories; and care models and nurses’ critical reasoning about the applicability of nursing theories.

Background: The 24 h urgent care units (24 h UCU) in Brazil are the main pre-admission hospital process of the public healthcare system and constitute an intermediate modality between primary care and hospital care. These units also provide care in cases of less severity that are not considered urgent. This study aimed to create and validate the content of a graphic protocol and checklist for the nursing care management of patients with a suspicion or confirmation of infection by COVID-19 at urgent care units. Methods: A methodological study was carried out in three phases: construct of items and dimensions of the checklist; evaluation of the checklist by specialists for content validation; and construct and content validation of the graphic protocol. Results: The checklist was evaluated by nine specialists. Eight items received suggestions for changes. Items with a content validity index ≥0.83 were maintained. With regard to content validity, despite the satisfactory level of agreement, the specialists suggested some changes in the writing of eight items. The graphic protocol was evaluated by six specialists and had an overall content validity of 0.97. Conclusion: The checklist with 44 items and three dimensions (Management, Biosafety and Care) and the protocol achieved a satisfactory standard of content validity for use at 24 h urgent care units. This protocol can contribute to the standardization and guidance of nursing actions in suspected and confirmed cases of COVID-19 at urgent care units, ensuring safe care based on scientific evidence.
