Question 1: An airplane made a rough landing after experiencing technical issues. Once in secure ground contact, the crew is aware of what to
- Exit the aircraft immediately and meet other crew members downwind from the aircraft.
- Stay in the aircraft until the pilot states it is safe to exit.
- Exit the aircraft after moving the patient out and secure shelter in the shade of the aircraft.
- Exit the aircraft after all moving parts have stopped and then meets other crew members at 12 o’clock. (Correct answer)
Correct answer: Exit the aircraft after all moving parts have stopped and then meets other crew members at 12 o’clock.
After a hard landing, crew must wait until all moving parts (rotors/propellers) have fully stopped before exiting, then regroup at the 12 o'clock (nose) position away from the tail rotor and hazards. Exiting immediately risks injury from spinning components, and meeting downwind places the crew near hot exhaust and fumes.
Question 2: Long-distance, high-altitude fixed-wing transport is being used to move a patient with pulmonary edema. Because of the patient's worsening respiratory condition, bi-level positive airway pressure (BiPAP) treatment is started. How many centimeters of water (cm H2O) should be set as the initial pressure setting for inhalational positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP)?
- 10/5 (Correct answer)
- 6/3
- 40/20
- 25/15
Correct answer: 10/5
In the case of a patient with pulmonary edema being transported via long-distance, high-altitude, fixed-wing transport and experiencing a deteriorating respiratory status, initiating bi-level positive airway pressure (BiPAP) therapy can be beneficial. The initial pressure settings for inspiratory positive airway pressure/expiratory positive airway pressure (IPAP/EPAP) typically depend on the individual patient's condition and the recommendations of the medical professionals involved. However, a common starting point for IPAP/EPAP settings in this scenario is 10/5 centimeters of water (cm H2O).
Question 3: When an asthmatic patient is transported by air, noninvasive ventilation is started. The patient experiences considerable hypotension shortly after takeoff, although the oxygen saturation level stays at 95%. This deterioration's most likely source is
- Pneumothorax
- Hyperinflation (Correct answer)
- Hypercapnia
- Hypovolemia
Correct answer: Hyperinflation
In the given scenario, where noninvasive ventilation is initiated during the air transport of a patient with asthma, and the patient becomes significantly hypotensive while maintaining an oxygen saturation of 95%, the most likely cause of this deterioration is hyperinflation.
Question 4: After a car accident, a 50-year-old guy with chest trouble is being transported by the flying crew. On the right side of the midlung field, an air space consolidation may be seen on a chest radiograph. This discovery suggests that
- Cardiac tamponade
- Pulmonary contusion (Correct answer)
- Hemothorax
- Pneumothorax
Correct answer: Pulmonary contusion
The chest radiograph revealing airspace consolidation in the midlung field on the right side in a 50-year-old man with chest pain following a motor vehicle collision is indicative of a pulmonary contusion.
Question 5: An individual suffers from barotitis media while flying in a fixed-wing aircraft. Pain is not lessened by descending more slowly. Another therapy option is
- Applying supplemental oxygen.
- Providing hearing protection
- Advising the patient to maintain ahead-down position
- Instructing the patient to perform the Valsalva maneuver. (Correct answer)
Correct answer: Instructing the patient to perform the Valsalva maneuver.
Another option for treating barotitis media in a patient during descent in a fixed-wing aircraft is instructing the patient to perform the Valsalva maneuver.
Question 6: From the intensive care unit to another institution, a patient is being moved. In-flight assessment suggests a postoperatively abrupt shift in mental state, and the patient is now having trouble responding to questions and reports seeing visual hallucinations. The nurse gets ready to provide medicine.
- haloperidol (Haldol), 0.5 to 2 mg IV. (Correct answer)
- lorazepam (Ativan), 1 to 2 mg IV.
- Midazolam (Versed) 0.5 to 1 mg IV.
- Clonidine (Duraclon), .0.1 mg PO.
Correct answer: haloperidol (Haldol), 0.5 to 2 mg IV.
In the given scenario, where a patient being transported from the ICU to another facility experiences an acute change in mental status postoperatively, difficulty answering questions, and visual hallucinations, the nurse prepares to administer haloperidol (Haldol) intravenously (IV) at a dose of 0.5 to 2 mg.
Question 7: The emergency locator transmitter (ELT) of an airplane transmits distress signals on the frequency of 121.5 MHz, which are picked up by
- Emergency position indicating radio beacons
- Digital duplex radios
- Search and rescue satellite systems
- Ground-based receivers only (Correct answer)
Correct answer: Ground-based receivers only
Distress signals transmitted by an aircraft's Emergency Locator Transmitter (ELT) on the 121.5 MHz frequency are received by ground-based receivers only.
An airplane made a rough landing after experiencing technical issues.
