PAPER 2026 FULL Q&A STUDY GUIDE
GRADED A+
◉Rocky mountain spotted fever. Answer: can be fatal if not treated
early, passed on by brown dog tick, fevers, chills, HA, rash on soles,
ankles, palms, wrists, and forearms, treat with doxycycline
◉Jellyfish treatment. Answer: apply acetic acid (vinegar) to
deactivate after removing tentacle and irrigating
◉Scabies. Answer: Apply cream head to toe, two applications one
week apart, wash clothes in hot water, vacuum,
parasite, skin to skin contact,
pruritis increases at night
like moist areas, palms, groins
◉Arterial Gas Embolism. Answer: dyspnea, pink, frothy sputum,
altered LOC, results from diving emergency, high pressure air forced
into circulation
tx with O2, needle decompression,
avoid trendelenburg
,◉Decompression sickness. Answer: presence of gas bubbles in the
blood and tissue,
presented with paresthesias, SOB, crepitus, HA, visual disturbances
AKA the bends, treat with O2, fluids, Heliox(helium with oxygen)
which decreases nitrogen
◉Frostbite. Answer: misleading injury, may take several days/weeks
to determine extent of damage
GENTLY handle tissue, do not rub tissue, wrap in loose bulky
dressing, debride only non-hemorrhagic blisters, circulating warm
water for 15-30 min,
◉Hypothermia considerations. Answer: V-fib refractory until
rewarmed, J waves present in moderate, volume replacement
necessary, rewarm body core to prevent rewarming shock, caution
with IV meds
◉activated charcoal contraindications. Answer: iron, lead, lithium,
caustics, toxic alcohols, corrosive agents, hydrocarbons, decreased
bowel sounds
◉gastric lavage. Answer: washing out of the stomach, considered for
life threatening poisonings with symptomatic pts presenting within
1 hour of ingestion
, ◉sympathomimetics. Answer: drugs that mimic the effects of the
sympathetic nervous system, ex cocaine and meth, interventions
include pt sedation, cooling
◉Flumazenil (Romazicon). Answer: Benzodiazepine antagonist,
reversal agent
◉Cholinergic. Answer: Neurons that release acetylcholine of the
parasympathetic nervous system
◉SLUDGE. Answer: Salivation
Lacrimation
Urination
Defecation
Gastrointestinal Distress
Emesis
overstimulation of cholinergic drugs
◉Pralidoxime (2-PAM). Answer: Reactivation of
Acetylcholinesterase, therefore decreases acetylcholine
