32
meds that can be given by ET tube
``` LANE Lidocaine Atropine Narcan Epinephrine ```
33
atropine indications

35
target lesion that becomes necrotic and is usually self limited
brown recluse (loxosceles recluse)
36
puncture wound that then develops systemic symptoms (muscle aches and HTN)
black widow (latrodectus mactans)
37
black widow treatment
benzodiazepines for muscle spasm, antivenin if supportive measures aren't working
38
nonvenomous snake bites management
wound cleaning and tetanus
39
venomous snake bite management
immobilize limb and let it hand at side
40
severe head injuries can lead to
SIADH
41
tearing of small blood vessels of the Pia mater
subarachnoid hemorrhage
42
lucid period followed by deterioration later
epidural hematoma
43
bloody atrauamtic LP think
epidural hematoma or herpes
44
lens shaped bleed
epidural hematoma - emergent surgical intervention
45
head CT after head trauma if
prolonged LOC, protracted vomiting, progressive headaches, retrograde amnesia, lethargy
46
most common skull fracture
linear parietal fracture
47
hemotympanum, hearing loss, facial paralysis and CSF otorrhea
temporal bone fracture
48
clear rhinorrhea, ecchymoses behind hear, periorbital ecchymoses
basilar skull fracture
49
increased risk of what w. basilar skull fracture
meningitis
50
basilar skull fracture may involve
6th and 7th nerve palsies
51
non accidental burns
full thickness, stocking and glove, distinct margins, varying depth
52
how many half lives for 97% of drug to be cleared
five
53
how many half lives to reach a steady state
five after most recent dose change
54
meds that cannot be taken with dairy
tetracycline, doxycycline and ciprofloxacin
55
meds that can't be taken with iron supplements
antacid
56
meds that inhibit CYP
erythromycin, ciprofloxacin, cimetidine, omeprazole (cause increased bioavailability/toxicity of beta blockers, warfarin, metronidazole)
57
meds that induce CYP
rifampin, phenobarbital, carbamazepine, phenytoin (cause faster elimination of beta blockers, warfarin, metronidazole)
58
meds that inhibit renal metabolism of digoxin
quinidine and amiodarone
59
beta blocker CNS side effect
trouble sleeping
60
beta blocker smooth muscle side effect
bronco spams and cold extremities
61
beta blocker cardiac side effect
bradycardia and heart block
62
cardioselective beta blocker
atenolol (propranolol is not and could exacerbate asthma)
63
acetazolamide MOA
causes metabolic acidosis - prevents reuptake of bicarb in proximal tubule which make urine alkaline
64
loop diuretic MOA
blocks absorption of Na and Cl and results in wasting Ca, K+ and H+, resulting in hypochloremic hypokalemic metabolic alkalosis
65
thiazide MOA
blocks absorption of Na, Cl and water at distal tubule resulting in contraction metabolic alkalosis
66
mannitol MOA
keeps water in tubules with osmotic diuresis without an acid base effect
67
potassium sparing diuretic
spironolactone
