RICKY'S CFRN STUDY GUIDE| 140 questions| WITH
COMPLETE ANSWERS
MI PATTERNS Correct Answer: LISA P.
LATERAL: I,aVL, v5,v6 (LCA/RCA-high lateral wall L Vent)
INFERIOR: II, III, aVF (RCA-inferior & posterior wall L Vent)
SEPTAL: V1, V2 (LCA/bundle branches)
ANTERIOR: V3, V4 (LCA-anterior wall L Vent)
POSTERIOR: V1,V2,V3,V4:ST Depression (RCA/LCA-L Vent posterior wall)
Charles's Law Correct Answer: Gas pressure increases as Temp increases
Gas expands in a heated tank
Henry 's Law Correct Answer: Decompression
Dalton's Law Correct Answer: Molecules shrink under pressure. It takes more molecules to fill
the same space. More altitude=more O2 needed.
Graham's Law Correct Answer: Diffusion rate of gas thru a liquid is related to solubility of the
gas. Higher to Lower Concentrations. (mucous in the lungs with O2
Boyle's Law Correct Answer: Trapped gas expands with altitude. (Air splints, Chest tubes, ET
Tubes, Bowels)
Gay-Lussac's Law Correct Answer: Pressure in the tanks go down as temperature goes down
Murphy Sign Correct Answer: Gallbladder, unable to take deep breath upon palpation under the
right ribs.
Cullen Sign Correct Answer: Retroperitoneal bleed, pancreatitis, Trauma, Bruising of the
umbilicus.
Grey-Turner Sign Correct Answer: Retroperitoneal bleed, pancreatitis, Trauma, Bruising of the
flanks.
Asterixis Correct Answer: Liver, Hepatitis, Hands held out and shaking
Cushing's Reflex Correct Answer: Increased ICP, widening pulse pressure, bradycardia, resp
changes (cheyne stokes).

2: optic-vision
3: occulomotor-eye opening/pupil constriction
4: troclear-up/down eye movement
5: trigeminal-chewing/ facial sensation
6: abducens-right/left eye movement
Cranial Nerves 7-12 of 12 Correct Answer: 7: facial-taste/ mouth movement/ tears/ saliva
8: acoustic-hearing/ equilibrium
