The full form of GAS in the context of response to stress is:

Appeared in: ESIC Nursing Officer -2019 (Shift -1)

Explanation

GAS is the acronym for General Adaptation Syndrome, a model describing the body's physiological response to stress.
The concept was developed by Hans Selye, who identified it as a three-stage process.
The three stages are Alarm, Resistance, and Exhaustion.
This model explains how the body first reacts to a stressor, then tries to adapt, and finally becomes depleted if the stress is prolonged.

Option A: The correct term is 'syndrome,' not 'system.' A syndrome refers to a collection of symptoms and signs that characterize a specific condition, which accurately describes the body's multifaceted response to stress.
Option C: This is incorrect. 'Alarm' is the name of the first stage of the General Adaptation Syndrome, not part of the name of the syndrome itself. 'Signals' is also not part of the official terminology.
Option D: This option incorrectly combines the name of the first stage ('Alarm') with the word 'syndrome.' The correct name for the entire three-stage process is General Adaptation Syndrome.

Clinical Relevance

Nursing practice connection: Knowing General Adaptation Syndrome (GAS) helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses use the GAS model to assess a patient's stress level and identify signs of chronic stress that could lead to the exhaustion phase.
Recognizing the stage of GAS helps in planning interventions, such as teaching coping mechanisms during the resistance stage to prevent progression to exhaustion.
Patient education about the effects of stress on the body, based on the GAS model, can empower them to manage stress more effectively.

How to Approach the Question

First, identify the keywords in the question: 'GAS' and 'response to stress'. This indicates the question is asking for a specific term from psychology or physiology.
This is a factual recall question. Access your knowledge about major stress theories.
Recall that Hans Selye's model for stress response is known as the General Adaptation Syndrome (GAS).
Evaluate the options. 'General adaptation syndrome' exactly matches the recalled term.
Eliminate the other options: 'system' is incorrect terminology, and 'alarm' refers to a stage within the syndrome, not the syndrome's name.
