NUR 2063 Pathophysiology Exam 1
- What is Pathophysiology
Answer is the study of what happens when the normal anatomy and physiology go wrong, causing disorder and disease process of the human body.
- What 4 things does pathophysiology include?
Answer Etiology, Pathogenesis, Clinical Manifestations, and Treatment Implications
- What is etiology
Answer study of causes or reasons for phenomena. Includes Idiopathic conditions that have an unknown origin or cause.
- What is pathogenesis?
Answer development or evolution of disease from initial stimulus to the expression of manifestations as time occurs.
- What are clinical manifestations?
Answer Signs and symptoms of disorder.
- What are treatment implications?
Answer Which combine the etology, pathogenesis, and clinical manifestations to determine the best treatment of condition per individual.
- What are signs?
Answer Objective or observed manifestations of disease. 1 / 4
- What are symptoms?
Answer Subjective feelings of abnormality in the body.
- What is objective data
Answer What you observe and can measure.
- What are examples of objective data?
Answer rash, low blood pressure, bleeding
- What is subjective data?
Answer What the patient may report to you
- What are examples of subjective data?
Answer pain scale, they feel suicidal, fatigued.
- What is epidemiology?
Answer 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?
Answer Primary, Secondary, Tertiary
- Explain Primary Prevention
Answer "Preventing"; altering susceptibility or reducing exposure of disease for people.
- Examples of Primary Prevention 2 / 4
Answer Vaccinations and Handwashing
- Explain Secondary Prevention
Answer "Screening"; early detection, screening, and management of disease to catch disease early before it spreads
- Examples of Secondary Prevention
Answer PAP smears for STDs, lab work for HBA1C check, mammogram
- Explain Tertiary Prevention
Answer "Treating" and preventing further complications from a disorder or disease after the person has the condition
- Examples ofTertiary Prevention
Answer Rehab for hip surgery, relearning ADL's after amputation, Wound care after stroke to prevent pressure ulcers.
- What is homeostasis?
Answer 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?
Answer ability to successfully adapt to challenges. It is not a balance but an attempt to adapt to achieve homeostasis. Example
Answer sweating to lower ones body temp.
- Stages of the General Adaptation Syndrome 3 / 4
Answer alarm, resistance, exhaustion
- Explain alarm stage of general adaptation syndrome
Answer Where the sympathet- ic 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
Answer 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
Answer 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?
Answer disease can occur physically and mentally, such as anxi- ety, depression, headaches, insomnia, infection, and heart disease.
- Name the hormones released during alarm stage of general adaptation syndrome
Answer Corticotrophin releasing hormone, adrenocorticotrophic hormone, cat- echolamines( norepinephrine and epinephrine) and cortisol
- Explain the Role of corticotrophin releasing hormone in alarm stage
- / 4
Answer acti- vates the sympathetic nervous system and adrenocorticotropic hormone.
