A 32-year-old man who was stung by a bee has diffuse hives, facial swelling, and difficulty breathing. When he breathes, you hear audible stridor. What does this indicate?
A: Swelling of the upper airway structures
B: Narrowing of the two mainstem bronchi
C: Swelling of the lower airway structures
D: Narrowing of the bronchioles in the lungs - ANSWER-A: Swelling of the upper airway structures
Reason:
This patient is experiencing a severe allergic reaction (anaphylaxis). Stridor, which is a high-pitched sound heard on inhalation, indicates swelling of the structures and tissues of the upper airway. If not promptly treated, the patient's airway may close completely, resulting in respiratory arrest. Narrowing of 1 / 4

the bronchioles in the lungs causes wheezing, a whistling sound that may be heard during inhalation, exhalation, or both.
When an error occurs while using the AED, it is MOST often
the result of:
A: malfunction of the microchip inside the AED.
B: battery failure secondary to operator error.
C: misinterpretation of the patient's cardiac rhythm.
D: excess patient movement during the analyze phase. -
ANSWER-B: battery failure secondary to operator error.
Reason:
AEDs have a high specificity for recognizing shockable rhythm (eg, V-Fib, pulseless V-Tach); this means that they are highly reliable. It would be extremely rare for the AED to recommend a shock when one is not indicated or fail to recommend a shock when one is indicated. When an error does occur, it is usually the operator's fault. The most common error is not having a charged battery. To avoid this problem, many AEDs are equipped with an alarm that warns the operator if the battery is not fully charged. Some of the older AEDs, however, are not 2 / 4

equipped with this feature. Therefore, it is important to check the AED daily, exercise the battery as often as the manufacturer recommends, and always have a spare, fully-charged, battery on hand.
A young male has trauma to multiple body systems after he fell approximately 35 feet. He is semiconscious, has an unstable chest wall, numerous long bone fractures, and a large hematoma to his head. He will have the GREATEST chance for survival if
you:
A: rapidly transport him to a trauma center.
B: keep him warm and elevate his legs.
C: request an ALS ambulance.
D: give him high-flow oxygen early. - ANSWER-A: rapidly transport him to a trauma center.
Reason:
When caring for a patient with major trauma, rapid transport to a trauma center is essential and will afford the patient the best chance for survival. This is especially true if the patient has trauma to multiple body systems. Definitive care cannot be 3 / 4

provided in the field; this requires resources and personnel at the hospital. Oxygen administration and shock management (eg, applying blankets, elevating the legs) may help prevent the patient's condition from deteriorating, and although these are important, they are not definitive interventions. In certain situations, it would be prudent to request ALS personnel at the scene (eg, lengthy extrication, unavoidable scene delay); however, in the absence of such extenuating circumstances, it is clearly more important to transport without delay. En route to the trauma center, consider a rendezvous with an ALS unit if it is possible and will not delay transport.
Which of the following scene size-up findings is LEAST suggestive of an unsafe environment?
