Aggression01:47

Aggression

27.9K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

SBAR II: Application of SBAR

4.5K
SBAR is an effective communication tool used by healthcare professionals to communicate patient information accurately. SBAR stands for Situation, Background, Assessment, and Recommendation. For a better understanding, an example is given below.
SBAR Report from a Nurse to a Health Care Provider
S: "Hello, Dr. Smith. This is Jane, RN, from the Med Surg unit. I am calling to tell you about Ms. White in Room 210, who is experiencing increased pain and redness at her incision site. Her recent...

Agonism and Antagonism: Quantification01:14

Agonism and Antagonism: Quantification

444
When drugs are administered, they can elicit either an agonist or antagonist effect on the body. Agonism occurs when a drug activates a specific receptor, triggering a biological response. On the other hand, antagonism happens when a drug binds to the same receptors but blocks their activation, thereby preventing a biological response.
To quantify these effects, researchers use a dose-response curve, which provides valuable information about the potency and efficacy of a drug. Potency refers to...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

1.1K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

SBAR I: Understanding the Concept

4.6K
Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
Standardized methods of communication have been developed to ensure that information is...

The Scientific Method02:40

The Scientific Method

59.9K
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.

Area of Science:

  • Urban planning and architecture
  • Criminology and sociology
  • Healthcare facility design

Background:

  • Healthcare workers face high rates of workplace assaults, with poor environmental design contributing to aggression.
  • Emergency departments are particularly vulnerable settings for patient and companion-driven violence.

Purpose of the Study:

  • To evaluate space syntax as a tool for identifying aggression risks in emergency departments.
  • To explore interventional opportunities and environmental design strategies to mitigate Type II violence.

Main Methods:

  • Utilized five visibility graph analysis (VGA) measures: visibility, control, controllability, mean visual depth, and occlusivity.
  • Applied VGA to three U.S. hospital emergency departments, analyzing original and modified layouts.
  • Incorporated theories such as Rational Choice Theory and Crime Prevention through Environmental Design (CPTED).

Main Results:

  • Significant differences in VGA measures were observed between different layouts and between original and modified designs.
  • Architectural features, even minor ones, impact visual access and exposure, as measured by space syntax.
  • Alcove-style staff areas were linked to reduced visual control, while central workstations in smaller zones improved control over patient areas.

Conclusions:

  • Space syntax analysis is a valuable tool for pinpointing aggression risks within hospital environments.
  • The study demonstrates the utility of space syntax in identifying opportunities for intervention and improving safety through design.
