DIT Flashcards
(363 cards)
beta 2 Receptor actions
vasodilation (mild), bronchodilation, elevation of lipolysis and insulin, decrease in uterine tone
adrenergic receptor types in skeletal muscle
alpha 1 and beta 2
Zosin drugs–>what are they? what are they used for?
alpha 1 blockers; use for HTN and BPH (relax bladder neck muscles; especially Tamsulosin alpha 1A/D–>better for pts with BPH without HTN)
pheochromocytoma treatment
alpha blocker first: phentolamine/phenoxybenzamine
beta blocker
HTN and bradycardia patient–>how to treat
use acebutaolol or pindolol–>very weak beta 1/beta 2 agonists that are so weak they act as antagonists–>leads to less pronounced heart blocking effect
Alpha 1 and beta 2 blockers?
carvedilol/ labetalol
arotic dissection treatment
beta blocker–>lower blood pressure and rate of BP increase during systole
what not to give pt with cocaine overdose?
beta blocker. Cocaine inhibits NE uptake… therefore blocking beta will result in alpha stimulation–>increase in HTN.
beta blocker SE
bronchoconstriction; hypoglycemia, arrythmia, rebound HTN
Timolol, nadolol
glaucoma
partial beta agonists acting as antagonists?
Pindolol, acebutaolol
Clonidine mech? use?
alpha 2 R blocker; used as sedative and malignant HTN
beta blocker contraindications/use caution
asthmatics; DM; CHF/heart block patients/brady cardia
Lithium Side effects (in adults)
- sedation/dizziness
- tremors (POSTURAL TREMOR!!!)
- sick sinus syndrome/heart block/bradycardia
- hypothyroidism/goiter
- polyuria (by blocking aquaporin)
Mania dx criteria
Distractability Irresponsibility Grandiosity Flight of ideas Activity (goal directed)/agitation Sleep decrease Talkativity
More than 1 month
Major Depression Dx criteria
more than 2 weeks must have loss of interest or depressive mood. plus 4 of the others.
Sleep changes Interest loss Guilt Energy loss Concentration loss Appetite loss Psychomotor sx Suicidal ideations
Risk factors of Suicide
Sex (male) Age (teenagers; elderly) Depression Previous attempts Ethanol Rational thought loss Sickness Organized plan No Spouse/no support
Acute pancreatitis causes
Gall stones Ethanol Trauma Scorpion sting Mumps Autoimmune Steroids Hyperlipidemia/hypercalcemia ERCP Drugs
Hypercalcemia sx
Stones, groans, psychiatric overtones
Hypocalcemia signs
trousseau’s sign; chvostek’s sign
Audio hallucination most associated with?
Visual Hallucinations most associated with?
Tactile formication?
olfactory hallucinations?
- auditory: schizophrenia
- visual: medical illness (dementia/drugs/migraine)
- tactile: alcohol withdrawal; cocaine user
- olfactory: epilepsy/brain tumor
gram positive cocci in pairs
strep pneumo
What is Ferritin?
Ferritin is an acute phase reactant protein that stores iron (hides it away if there’s an infection)
Calcium D synthesis/activation organs?
cholecalciferol (synthesized in skin/ingested in milk) or ergocalciferol from plants–>liver converts to 25 hydroxyD–>kidney converts to 1,25 hydroxyD
