General Adaptation Syndrome (GAS)
- three-stage physiological response that appears regardless of the
stressor that is encountered
1. alarm reaction
2. resistance stage
3. exhaustion stage
alarm reaction (GAS)
- first stage of GAS
- activates the sympathetic nervous system
- fight-or-flight
resistance stage of GAS
- second stage of GAS
- body attempts to cope with the stressor
- parasympathetic nervous system over-rides the sympathetic nervous
system
- body functions normalize while responding to the stressor. The
Exhaustion stage of GAS
- third stage;
- body functions are no longer able to maintain an adaptive response
to the stressor
- can lead to death
Characteristics of alarm reaction stage of GAS
- decreased urine output
- increased
------>heart rate
------>respiratory rate
, ------>blood glucose
------>blood flow to skeletal muscles
------>blood pressure
------>mental acuity
importance for evidence-based practice
- uses latest research & evidence
- ensures nursing practices are up-to-date, safe & based on proven
methods
Where to find evidence-based practice
- most current journals
Steps to Evidence-Based Practice (EBP)
1. ask clinical questions (PICOT)
2. collect & critique data
3. share outcomes
PICOT format of clinical questions
P - patient
I - intervention
C - comparison
O - outcome
T - time
Mitosis
- cell division
- 4 stages
Stages of Mitosis
1. prophase,
2. metaphase,
