Lecture 1 Intro Flashcards
Patho
Disease
Physiology
Study of function
Patho physiology
Study of the disease process
Roles of the nurse
- Prevention of disease
- Early Case findings
- minimizing impact of illness
- Promoting healing and preventing more problems
- Maximizing patients potential
Why do nurses study disease
Prevent Identify Respond Reduce Redirect disease burden
Pathogenesis
How the disease process evolves
Etiology
What she’s the disease process in motion
Idiopathic
Unknown
Risk factors
Contributions that inc. the chances that certain disease will occur
What does the nurse do
Facilitate
Educate
Motivate
Disease
Interruption, cessation, or disorder of a body system or organ structure. Abnormal functioning occurs
Illness
Feelings that come w/having a disease (subjective)
Stages of disease and illness
Sub clinical or pre-clinical
prodromal
clinical
Sub clinical or pre-clinical
Disease is present but patient is unaware
Prodromal
Vague stage and non-specific manifestations
Clinical
Disease is evident and identifiable C=clear
Sign
Objective and measurable finding
“Something I can detect” I in sign
Symptom
Subjective feeling
Prognosis
Prediction about outcome
Sequelae
Subsequent injuries related to the disease process
Complications
New problems in addition to the original disease process
CDC
Centers for disease control and prevention
Morbidity
of ill per 100,000
Mortality
who died per 100,00
Indidence
new cases
Epidemic
Rapid increase in incidence noted
OSHA
Occupational health and safety administration
Assure safe and healthful working conditions by setting standards, education, assistance
EPA
environmental protection agency
Purpose of protecting human health and environment by enforcing regulations
WHO
World Health Organization
Speciality agency of UN concerned with international public health
Passive transport
Requires no energy
Diffusion, osmosis, filtration, and facilitated diffusion
Active transport
Requires energy
Includes transport by pumps and vesicles
Diffusion
Passive transport of particles from an area of higher to lower concentration
Concentration gradient
Difference in concentration from one point to another
Osmosis
Difusión of water down the concentration gradient through selective permeable membrane
Tonicity
The ability of a solution to affect the fluid volume and pressure in a cell through osmosis
Isotonic
Solution a/same concentration (equal into and out of cell rate)
Cell remains normal
Hypertonic
Solution w/higher concentration
Water will diffuse out of cell=shrivel
Hypotonic
Solution w/lower concentration
Water will move by osmosis into cell and burst
Facilitates diffusion
Passing through transporter
Filtration
Water and dissolved particles are forced across a membrane from an area of higher to lower pressure
