Current Trends in Nursing II

3.3K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Uncertainty: Overview00:59

Uncertainty: Overview

1.4K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

The Scientific Method

64.5K
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Evolutionary Psychology

824
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Cognitivism

2.6K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Emerging Adulthood01:27

Emerging Adulthood

511
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Area of Science:

  • Anesthesiology
  • Perioperative Medicine
  • Neuroscience

Background:

  • Emergence agitation (EA), or emergence delirium, presents significant clinical challenges.
  • The underlying mechanisms of EA are not fully understood.
  • Identified risk factors include patient demographics, surgical characteristics, anesthetic agents, and postoperative conditions.

Purpose of the Study:

  • To review current research on the outcomes of emergence agitation.
  • To explore potential predictive monitoring for EA.
  • To discuss current and future research directions for EA prevention and management.

Main Methods:

  • Literature review of studies on emergence agitation.
  • Analysis of proposed risk factors and preventive strategies.
  • Discussion of assessment tools and their variability.

Main Results:

  • Numerous risk factors for EA have been proposed, but a clear predictive model is lacking.
  • Various interventions, including total intravenous anesthesia and multimodal analgesia, may prevent EA.
  • Standardized guidelines and consistent assessment methods for EA are absent, leading to variable incidence rates.

Conclusions:

  • Predictive monitoring for EA could mitigate adverse consequences.
  • Identifying high-risk patients and applying targeted preventive measures remain challenging.
  • Further research is needed to standardize EA assessment and refine preventive strategies.
