Which gas law explains why a pneumothorax expands as an unpressurized cabin ascends?
✔Correct Answer-Boyle's law
Request the pilot fly at the lowest, safest altitude.
Gases expand at higher altitudes ✔Correct Answer-Boyle's law
Which gas law explains why oxygen tank pressures may change between takeoff and at
altitudes? ✔Correct Answer-Gay-Lussac's Law
Oxygen tank pressures decrease at higher altitude due to cooler temperatures shrinking gases
✔Correct Answer-Gay-Lussac's Law
Which gas law depicts why flight crews may be able to transport an obese patient in an aircraft
in winter that they couldn't transport in warmer months? ✔Correct Answer-Charle's Law
Describes how cooer air is denser, allowing the wings to create more lift in cold temperatures
✔Correct Answer-Charle's Law
Night vision deterioration starts at what altitude? ✔Correct Answer-Night vision loss begins at
5,000 ft in the indifferent stage of hypoxia, along w/ an increase respiratory and heart rate.
What does hypoxia hypoxia cause? ✔Correct Answer-Impedes alveolar gas exchange. The
decreased barometric pressure at high altitude causes hypoxia, so hypoxia hypoxia may be
referred to as altitude hypoxia.
A patient w/ emphysema/COPD may experience which type of hypoxia during air transport?
✔Correct Answer-Hypoxic
A patient w/ an active GI bleed may experience which type of hypoxia during transport?
✔Correct Answer-Hypemic hypoxia
(rhymes w/ anemic, cellular hypoxia largely due to blood loss or anemia)
Pts w/ carbon monoxide and cyanide exposure may experience which two types of hypoxia?
✔Correct Answer-Histotoxic and Hypemic
Historic Hypoxia - alcohol, cyanide, and carbon monoxide poisoning, resulting in the cells
inability to use oxygen.
Cyanide poisoning tx ✔Correct Answer-Hydroxycobalamin
,Increase in attitude increases or decreases humidity and temperature ✔Correct Answer-
decreases both
What injuries are expected from overpressure after an explosion? ✔Correct Answer-
Pneumothorax.
Occurs when the shock wave travels through the air and damages the grass filled organs like the
lunges. Second injury is from flying debris, thus penetrating injury.
Tertiary head injuries from being thrown to the ground.
Quaternary injuries from burns.
Undergarments worn under the fire resistant flight suit should be made of natural fibers and
should be made of natural fibers, how much air space should be between suit and garments?
✔Correct Answer-0.25 inch
When a helicopter lands on a slope or uneven terrain, what is the best way to approach and
depart the aircraft? ✔Correct Answer-From the downhill side, in a crouched position.
How do you manage an in flight emergency? ✔Correct Answer-aviate, navigate, communicate
The priorities are to retain control of the aircraft, choose and appropriate emergency landing
site, then report the emergency to the program communication center.
An impact that exceeds how many G's will automatically activate the emergency locator
transmitter? ✔Correct Answer-4
Which universal distress frequency transmits a digital signal including GPS location after ELT
activation? ✔Correct Answer-406MHz
The pilot fails to check the power during lift off and the helicopter impacts the ground and
smoke fills the cockpit. What is the nurse's priority action? ✔Correct Answer-Exit the aircraft
and meet at a pre-designated location (12 o'clock position)
Which intervention should be performed first for a patient in resp. distress due to a simple
pneumothorax? ✔Correct Answer-Chest Tube
Insertion should be performed prior to bipap, bipap can push a simple pneumothorax to a
tension pneumothorax.
Interpret ABG: pH 7.25, PaO2 40, HCO3 15 ✔Correct Answer-metabolic acidosis
Metabolic Acidosis conditions: ✔Correct Answer-ketoacidosis, salicylate, methanol, ethylene
glycol ingestion, renal failure, diarrhea, and lactic acidosis from shock.
Interpret ABG: pH 7.33, PaO2 32, HCO3 18 ✔Correct Answer-Partial compensated metabolic
acidosis
, Which induction agent is preferred in head trauma since it has little to no effect on MAP and
decreases ICP? ✔Correct Answer-Etomidate
drawbacks of etomidate is that it doesn't provide analgesia and possible adrenal suppression.
What is the amount of blood in the ventricles at end diastole? ✔Correct Answer-Preload
What law describes how increasing preload increases the ventricle stretch and subsequent
contraction? ✔Correct Answer-Sterlings law
What is the resistance the ventricles must overcome to eject blood into the pulmonary and
systemic circulation? ✔Correct Answer-Afterload
Normal dynes of SVR ✔Correct Answer-800-1200
Which shock is afterload decreased? ✔Correct Answer-Distributive Shock
septic, neurogenic, and anaphylactic
Which shock is afterload increased? ✔Correct Answer-Hypovolemic, cariogenic and
obstructive shock
Another word for SVR (systemic volume resistance)? ✔Correct Answer-Afterload
Does vasodilation or vasoconstriction occur in distributive shock? ✔Correct Answer-
Vasodilation
Does vasodilation or vasoconstriction occur in hypovolemic, cardiogenic, and obstructive shock?
✔Correct Answer-Vasoconstriction
What hemodynamic parameters are seen in EARLY sepsis? ✔Correct Answer-Increased CO
and SV, decreased SVR, CVP, and PAOP
What hemodynamic parameters are seen in hypovolemic shock? ✔Correct Answer-Decreased
CO, SV, CVP, PAOP and increase SVR
The patient has lost volume, so right and left preload is low, decreasing cardiac output and
stroke volume. Systemic vascular resistance is increased due to catecholamine release to
compensate for shock state.
What hemodynamic parameters are seen in cariogenic shock? ✔Correct Answer-Decreased
CO and SV, increased SVR, CVP, and PAOP
The patient has a left ventricular pump failure, so right and left preload is high due to inability to
pump, decreasing cardiac output and stroke volume. Systemic vascular resistance is increased.
