PHYSIOLOGICAL ADAPTATION
(NURSING) EXAM
QNS & ANS
2023/2024
,1. What is physiological adaptation and why is it important for health care professionals to
understand it?
- Physiological adaptation is the process by which the body adjusts to changes in its internal or
external environment, such as temperature, oxygen, stress, infection, injury, etc. It is important
for health care professionals to understand it because it affects the diagnosis, treatment, and
prevention of various diseases and disorders, as well as the recovery and well-being of patients.
2. What are some examples of physiological adaptation in response to stress?
- Some examples of physiological adaptation in response to stress are the activation of the
sympathetic nervous system, which increases heart rate, blood pressure, respiration, and
glucose levels; the release of cortisol and other hormones, which modulate inflammation,
immunity, and metabolism; and the alteration of gene expression, which influences cellular
functions and behaviors.
3. What are some factors that influence the degree and direction of physiological adaptation?
- Some factors that influence the degree and direction of physiological adaptation are the type,
intensity, duration, and frequency of the stressor; the individual's genetic makeup, age, sex,
health status, and previous experiences; and the availability and effectiveness of coping
resources and strategies.
4. What are some consequences of maladaptive physiological adaptation?
- Some consequences of maladaptive physiological adaptation are chronic inflammation,
impaired immunity, metabolic disorders, cardiovascular diseases, neurodegenerative diseases,
psychiatric disorders, and reduced quality of life.
5. What are some interventions that can promote positive physiological adaptation?
- Some interventions that can promote positive physiological adaptation are stress management
techniques, such as relaxation, meditation, mindfulness, cognitive-behavioral therapy, etc.;
lifestyle modifications, such as exercise, nutrition, sleep hygiene, social support, etc.;
,pharmacological treatments, such as anti-inflammatory drugs, antidepressants,
antihypertensives, etc.; and biofeedback devices, such as heart rate variability monitors,
electroencephalograms, etc.
6. What is homeostasis and how is it related to physiological adaptation?
- Homeostasis is the state of equilibrium or balance in the body’s internal environment. It is
maintained by various feedback mechanisms that regulate vital functions such as temperature,
Ph, blood pressure, blood glucose, etc. Physiological adaptation is the process by which
homeostasis is restored or maintained in response to changes in the external or internal
environment.
7. What are some examples of homeostatic mechanisms in the human body?
- Some examples of homeostatic mechanisms in the human body are thermoregulation,
which involves sweating, shivering, vasodilation, vasoconstriction,
etc.; osmoregulation,
which involves thirst,
urination,
antidiuretic hormone,
etc.; glucose regulation,
which involves insulin,
glucagon,
glycogenolysis,
glycolysis,
etc.; blood pressure regulation,
which involves baroreceptors,
cardiac output,
vascular resistance,
renin-angiotensin-aldosterone system,
etc.
8. What are some disorders that result from homeostatic imbalance?
- Some disorders that result from homeostatic imbalance are diabetes mellitus,
which is caused by insufficient insulin production or action; hypertension,
which is caused by excessive blood pressure; hypothermia or hyperthermia,
which are caused by inadequate thermoregulation; dehydration or edema,
which are caused by abnormal fluid balance; acidosis or alkalosis,
