Nursing Interventions II: Selecting and Classifying the Nursing Interventions01:29

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

2.9K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Routes of Persuasion02:20

Routes of Persuasion

68.3K
Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Heuristics01:21

Heuristics

337
Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

Protecting Self-Esteem01:27

Protecting Self-Esteem

118
Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...

Strategies for Assessing and Addressing Confounding01:25

Strategies for Assessing and Addressing Confounding

253
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Trial and Error and Algorithm01:12

Trial and Error and Algorithm

291
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Area of Science:

  • Cognitive Psychology
  • Decision Science

Background:

  • Optimal Experimental Design (OED) models human information seeking behavior.
  • OED's descriptive and explanatory power in psychology is underexplored.

Purpose of the Study:

  • Investigate psychological strategies in information evaluation within probabilistic contexts.
  • Examine deviations from OED principles in naturalistic settings.
  • Assess the adaptiveness of information search strategies.

Main Methods:

  • Series of experiments using a crime investigation scenario.
  • Analysis of query and outcome evaluation.
  • Comparison of one-shot and stepwise information search tasks.

Main Results:

  • People do not strictly adhere to OED principles for query evaluation.
  • Distinct strategies, like identifying a leading contender early, are employed.
  • Zero-sum thinking and risk aversion influence information search strategies.

Conclusions:

  • Human information seeking deviates from purely information-theoretic models.
  • Contextual factors and learner preferences significantly impact decision-making.
  • Findings advance descriptive models of information seeking and evaluation.
