A 22-year-old man crashed his motorcycle into a tree. He is found approximately 20 feet away from his bike and is responsive to pain only. He is not wearing a helmet. You are unable to effectively open his airway with the jaw-thrust maneuver. What should you do?
A: Insert an oral airway and assess his breathing.
B: Carefully tilt his head back and lift up on his chin.
C: Apply high-flow oxygen and assess his carotid pulse.
D: Suction his oropharynx and reattempt the jaw-thrust. -
CORRECT ANSWER -B: Carefully tilt his head back and lift up
on his chin.

Regardless of the situation, you MUST be able to establish and maintain a patent airway. Without a patent airway, the patient will die. If you are unable to effectively open a trauma patient's airway with the jaw-thrust maneuver, you should carefully perform the head tilt-chin lift maneuver. You cannot assess, not to mention treat, a patient's airway if it is not open and clear of secretions or foreign bodies.
When is it MOST appropriate to clamp and cut the umbilical cord?
A: Before the newborn has taken its first breath
B: Immediately following delivery of the newborn
C: As soon as the cord has stopped pulsating
D: After the placenta has completely delivered - CORRECT
ANSWER-C: As soon as the cord has stopped pulsating
Reason:
Generally, it is safe to clamp and cut the umbilical cord once it has stopped pulsating and the baby is breathing adequately.When blood flow through the umbilical cord ceases, it will stop pulsating; this indicates that the baby is oxygenating its own 2 / 4

blood. If the cord does not stop pulsating and/or the baby is not breathing adequately, the cord should not be clamped and cut and the baby should be kept at the level of the mother's perineum and managed appropriately while en route to the hospital.
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 - CORRECT
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 3 / 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. -
CORRECT 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
