AIR METHODS PRE-HIRE EXAM 385 (ACTUAL / )

QUESTIONS AND VERIFIED ANSWERS

ST elevation is associated with myocardial injury

ST depressions is associated with ischemia, old infarction, digitalis toxicity

Q wave with ST elevation acute injury

Q wave with ST depression indeterminate

hemodynamic readings: hypovolemic

CVP: low , cardiac index: low, PAWP: low, SVR: high

shock index formula SI=HR/SBP (systolic BP)

• / 4

normal shock index

0.5-0.7

steps to determine shock/condition the PT is presenting

1. SVR, 2a.SVR <800 think distributive, 2b. cardiac index: high= septic,

low=neurogenic (brady or normal HR)/ anaphylactic (tachycardia) OR SVR >

1200 (hypovolemic), CVP: low= hypovolemic, high= cardiogenic shock or

RVMI, PCWP: low= RVMI, high= cardiogenic

hemodynamic readings: cardiogenic

CVP: high, Cardiac index: low, PAWP: high, SVR: high

hemodynamic readings: RVI

CVP: high, Cardiac index: low, PAWP: low, CVP: high

hemodynamic readings: septic

cardiac index: high, SVR: low, CVP: low

hemodynamic readings: neruogenic

cardiac index: low w/ normal HR or bradycardia, SVR: low

hemodynamic readings: anaphylactic 2 / 4

cardiac index: low w/ tachycardia, SVR: low

hemodynamic finding is expected in a PT with RIGHT ventricular MI elevated CVP

S/S pericarditis

classic sign: friction rub, CP radiating to back, CP relieved by sitting

up/forward, CP worsening when laying flat

treatment of pericarditis & what not to give

O2 administration, NSAIDS (toradol), corticosteroids. do NOT give:

nitroglycerin

S/S of endocarditis olsers nodes (red painful pads of digits), janeway lesions fat, purpuric, non painful hands and feet, subconjuctivital hemorrhages (eye roth spots), flu like symptoms/fever, fatigue/night sweats, CP/SOB

discrepancy between blood pressure values and pulse strength, a loud systolic murmur, and mediastinal widening on CXR are symptoms of aortic disruption/ dissection

aortic disruption/dissection should be considered in what kind of trauma 3 / 4

severe deceleration MVC

s/s of aortic dissection/rupture tearing/ripping chest pain in hypertensive pts that radiates to the back, systolic murmur, mediastinal widening, tracheal deviation, localized bulge on aortic notch

endocarditis triad fever, heart murmur, anemia

medications for aortic dissection nipride and beta-blockers

levines sign and its indication

clutching CP, indication: cardiac origin

kernigs sign and its indication laying flat, flex hip 90 degrees and then attempts to extend lower leg at knee,

indication: meningitis

brudzinski sign and its indication

hip and knee flexing while raising pts head and pushing on chest, indication:

meningitis/subarachnoid hemorrhage
