Aplicação da Liderança Situacional em enfermagem de emergência Aplicación del Liderazgo Situacional en la enfermería de emergencia Applying Situational Leadership in emergency nursing

Os objetivos do estudo consistiram em identificar a correspondência de opinião entre o enfermeiro de unidade de emergência e o pessoal auxiliar de enfermagem em relação ao estilo deliderança exercido pelo enfermeiro e o estilo que este profissional deveria adotar em relação ao nível de maturidade do liderado frente as atividades assistenciais desenvolvidas. O referencial teórico adotado foi a Liderança Situacional. Para o alcance dos objetivos, elaborou-se instrumentos que foram aplicados nos sujeitos (n=24) participantes da pesquisa.Os resultados demonstraram que o estilo mais exercido pelos enfermeiros foi o E3 (compartilhar) e que estes deveriam adotar em relação ao nível de maturidade do pessoal auxiliar, o estilo E4 (delegar) sugerindo que os liderados apresentam nível de maturidade alto (M4).<br>Los objetivos de este estudio fueron identificar la correspondencia de opinión entre el enfermero de unidad de emergencia y el personal auxiliar de enfermería con relación al estilo de liderazgo utilizado por el enfermero y el estilo de liderazgo que este profesional debería adoptar con relación al nivel de madurez del personal auxiliar de enfermería ante las actividades de cuidado desarrolladas. El Liderazgo Situacional fue adoptado como referencial teórico. Para alcanzar los objetivos, fueron elaborados instrumentos, que fueron aplicados en 24 participantes. Los resultados mostraron que el estilo de liderazgo más ejercido por los enfermeros fue el E3 (compartir). La mayoría de los sujetos consideró que el enfermero debería adoptar en relación al nivel de madurez del personal auxiliar el estilo de liderazgo E4 (delegar), sugiriendo que los liderados investigados presentan nivel de madurez alto (M4).<br>This study aimed to identify the correspondence of opinions between nurses and nursing staff members who work at the emergency unit regarding the leadership style performed by nurses and the style nurses must adopt considering the maturity level of nursing staff members and the care provided at the unit. Situational Leadership was adopted as a theoretical reference framework. In order to achieve these goals, instruments were elaborated and applied to 24 research participants. Results demonstrated that the leadership style nurses most frequently perform was E3 (participating), and that nurses should adopt leadership style E4 (delegating) in view of the nursing staff's level of maturity, suggesting that staff members present a high level of maturity (M4)

The art of auscultation: evaluating a patient's respiratory pathology

This article considers national policy drivers promoting the development of advanced assessment skills and practical procedures for the safe and effective use of the stethoscope in the clinical area. The evidence base underpinning effective use of the stethoscope in clinical practice is explored, including the preparation of the patient and the environment, applying infection control policies, and placing an emphasis on privacy and dignity. This is followed by a practical guide to auscultation technique of the respiratory system for nurses developing advanced practice skills

Why the Euler scheme in particle tracking is not enough: The shallow-sea pycnocline test case

During the last decades, the Euler scheme was the common “workhorse” in particle tracking, although it is the lowest-order approximation of the underlying stochastic differential equation. To convince the modelling community of the need for better methods, we have constructed a new test case that will show the shortcomings of the Euler scheme. We use an idealised shallow-water diffusivity profile that mimics the presence of a sharp pycnocline and thus a quasi-impermeable barrier to vertical diffusion. In this context, we study the transport of passive particles with or without negative buoyancy. A semi-analytic solutions is used to assess the performance of various numerical particle-tracking schemes (first- and secondorder accuracy), to treat the variations in the diffusivity profile properly. We show that the commonly used Euler scheme exhibits a poor performance and that widely used particle-tracking codes shall be updated to either the Milstein scheme or second-order schemes. It is further seen that the order of convergence is not the only relevant factor, the absolute value of the error also is.Delft Institute of Applied MathematicsElectrical Engineering, Mathematics and Computer Scienc
