pulmonary hypertension - ANSWER--elevated pulmonary
pressure resulting from an increase in pulmonary vascular
resistance to blood flow through small arteries and arterioles.
-increased afterload causes increase in RV size as contractility
cannot overcome the resistance
CVA (risk factors) - ANSWER-HTN, HLD, DM, Smoking,
FHx CVA, Hx
TIA/CVA,
AFib
action potential - ANSWER--sodium moves into cell
(depolarization)
-threshold potential must be reached
-potassium moves out of cell (repolarization)
-returns to resting potential by pumping sodium out of cell and
potassium back into cell
threshold potential - ANSWER-The minimum membrane
potential that must be
,reached in order for an action potential to be
generated.
absolute refractory period - ANSWER-The minimum length
of time after an
action potential during which another action potential
cannot begin.
relative refractory period - ANSWER-A period after firing when
a neuron is returning to its normal polarized state and will fire
again only if the incoming message is much stronger than
usual
caseous necrosis - ANSWER--degeneration and death of
tissue with a
cheese-like
appearance
-associated
with TB
tuberculosis - ANSWER--An infectious disease that may affect
almost all tissues of the body, especially the lungs
-airborne
-caseous necrosis
-1/4 of world population infected -> leading cause of death d/t
infectious disease
-high risk countries include Mexico, Phillippines, Gautamala,
China, Haiti, India -congregate settings such as homeless
shelters are high risk, including for employees
, -increased in the mid 90s d/t AIDS but have decreased since
2000s
isoniazid (INH) - ANSWER--antiTB
- take daily for 6-12 months and most likely with other meds
too -worked if 3 neg. sputum cultures, no temp.
- Liver toxicity (hepato) check liver fxn --> JAUNDICE
- Don't take with alcohol (liver fxn remember?)
- Take on empty stomach
polypharmacy (side effects) - ANSWER--
hallucinations
-appetite
alterations
-tiredness, decreased
alertness, AMS
-weakness,
falls
-
dizziness
-skin
rashes
-anxiety,
excitability
vertical transmission - ANSWER-when a parasite is
transmitted from a parent
to its
offspring
