Critical Care/Flight Paramedic Exam Questions With 100% Verified Correct Answers 2025/2026

Critical Care/Flight Paramedic Exam Questions With 100% Verified Correct Answers 2025/2026 Sickled cells - Correct Answer Red blood cells that are less deformable and do not pass through microcirculation as easily, cause an increase in blood viscosity, and are sequestered and destroyed by the liver and spleen Acute chest syndrome - Correct Answer Condition that accounts for 25% of premature deaths in patients with sickle cell disease; the leading cause of hospitalization and death of sickle cell patients; symptoms include fever, cough, chest pain, dyspnea, new infiltrates on chest x-ray; no definitive therapy, only supportive care Integrilin, ReoPro, and Aggrastat - Correct Answer The three glycoprotein IIb/IIa inhibitors that bind to a platelet receptor glycoprotein and inhibit platelet aggregation 760 mmHg/1 atm - Correct Answer Barometric pressure at sea level Physiologic zone - Correct Answer Atmospheric zone; sea level-10,000 ft; human body is well adapted; adequate pressure to allow for oxygen exchange, impairments are frequently due to changes in pressure (ascent or descent) Physiologically deficient zone - Correct Answer Atmospheric zone; 10,000-50,000 ft; noticeable deficits to humans; reduced barometric pressure results in poor oxygen exchange; most noticeable impairment is hypoxia (trapped gases can also cause hypoxia) Space equivalent zone - Correct Answer Atmospheric zone; 50,000-250,000 ft; environment incompatible with human life; pressurized suits and sealed cabins required; impairments include hypoxia, trapped gas, and emboli Boyle's Law - Correct Answer Gas law; When temperature remains constant, the volume of a gas is inversely proportional to its pressure; As a gas bubble ascends, it expands. As it descends, it gets smaller; P1(V1) = P2(V2) Charles' Law - Correct Answer Gas law; At a constant pressure, the volume of gas is directly proportional to its temperature; For every 1,000 ft (333 meters) of altitude increase, temperature decreases 2 degrees Celsius; V1/T1 = V2/T2 Ideal Gas Law - Correct Answer Gas law; created to explain Boyle's Law vs. Charles Law; It takes a large amount of temperature change to affect a small amount of volume; pV = nRT (absolute pressure of gas x volume = amount of substance x gas constant x absolute temperature)
