Correct Answers (Verified Pass)
• What 4 things does pathophysiology include? -✓✓Etiology, Pathogenesis,
Clinical Manifestations, and Treatment Implications
• What is etiology -✓✓study of causes or reasons for phenomena. Includes
Idiopathic conditions that have an unknown origin or cause.
• What is pathogenesis? -✓✓development or evolution of disease from initial
stimulus to the expression of manifestations as time occurs.
• What are clinical manifestations? -✓✓Signs and symptoms of disorder.
• What are treatment implications? -✓✓Which combine the etology,
pathogenesis, and clinical manifestations to determine the best treatment of
condition per individual.
• What are signs? -✓✓Objective or observed manifestations of disease.
• What are symptoms? -✓✓Subjective feelings of abnormality in the body.
• What is objective data -✓✓What you observe and can measure.
• What are examples of objective data? -✓✓rash, low blood pressure, bleeding
• What is subjective data? -✓✓What the patient may report to you
• What are examples of subjective data? -✓✓pain scale, they feel suicidal,
fatigued.
• What is epidemiology? -✓✓study of the patterns of disease involving
populations. Based on the spread and contact of diseases in people.
,• What are the levels of disease prevention? -✓✓Primary, Secondary, Tertiary
• Explain Primary Prevention -✓✓"Preventing"; altering susceptibility or reducing
exposure of disease for people.
• Examples of Primary Prevention -✓✓Vaccinations and Handwashing
• Explain Secondary Prevention -✓✓"Screening"; early detection, screening, and
management of disease to catch disease early before it spreads
• Examples of Secondary Prevention -✓✓PAP smears for STDs, lab work for
HBA1C check, mammogram
• Explain Tertiary Prevention -✓✓"Treating" and preventing further complications
from a disorder or disease after the person has the condition
• Examples of Tertiary Prevention -✓✓Rehab for hip surgery, relearning ADL's
after amputation, Wound care after stroke to prevent pressure ulcers.
• What is homeostasis? -✓✓a state of equilibrium in which all body systems are in
balance and the body is at its most optimal in functioning. Stable.
• What is allostasis? -✓✓ability to successfully adapt to challenges. It is not a
balance but an attempt to adapt to achieve homeostasis. Example: sweating to
lower ones body temp.
• Stages of the General Adaptation Syndrome -✓✓alarm, resistance, exhaustion
• Explain alarm stage of general adaptation syndrome -✓✓Where the
sympathetic nervous system is activated due to stress. Fight or Flight responses
are activated and energy is given off by the HPA axis to flee or fight the danger
ahead. Blood must be redirected to vital organs in this stage to give the organs
energy to work.
, • Explain Resistance stage of general adaptation syndrome -✓✓the activity of the
Parasympathetic Nervous system and the endocrine system to return the body to
homeostasis. The body should ultimately adapt to the stressor.
• Explain the exhaustion stage of general adaptation syndrome -✓✓Occurs when
the stressor is not removed or overcome in the body. The body can no longer
return to homeostasis after prolonged exposure to stressor. It causes the body to
be depleted and damaged that can lead to disease or death.
• What complications can occur if stressors are not resolved from general
adaptation syndrome? -✓✓disease can occur physically and mentally, such as
anxiety, depression, headaches, insomnia, infection, and heart disease.
• Name the hormones released during alarm stage of general adaptation
syndrome -✓✓Corticotrophin releasing hormone, adrenocorticotrophic hormone,
catecholamines( norepinephrine and epinephrine) and cortisol
• Explain the Role of corticotrophin releasing hormone in alarm stage -
✓✓activates the sympathetic nervous system and adrenocorticotropic hormone.
• Explain the role of norepinephrine during alarm stage -✓✓helps to slow down
certain organs such as the GI and GU systems to prepare the body for fight or
flight.
• Explain the role of epinephrine during alarm stage -✓✓Stimulates the fight or
flight response by increasing heart rate, bronchodilation of the lungs to increase
respirations and amount of air let in, dilates pupils to let more light in, stimulates
more glucose to be released.
• Explain the role of cortisol during alarm stage -✓✓released by ACTH reaching
the adrenal cortex, this allows for more energy creation to increase glucose and
to reduce inflammation. Suppresses the immune system.
• Explain the symptoms of a sympathetic nervous system response -✓✓Pupils
dilate, salivation inhibited, increase in HR, bronchodilation of airway, increased
respirations, glucose release, inhibit GI/GU.
