You respond to a local lake where a diver complains of difficulty breathing that occurred immediately
after rapidly ascending from a depth of approximately 30 ′. On assessment, you note that he has cyanosis
around his lips and has pink froth coming from his nose and mouth. You should:
a) position him supine with his head elevated 30°, suction his mouth and nose, hyperventilate him with a
bag-mask device, and contact medical control for further guidance.
b) suction his mouth and nose, apply high-flow oxygen, position him on his left side with his head down,
and contact medical control regarding transport to a recompression facility.
c) place him in a semi-sitting position, suction his mouth and nose, apply a continuous positive airway
pressure (CPAP) device, and transport to the closest emergency department.
d) suction his mouth and nose, keep him supine and elevate his legs to prevent air bubbles from
entering his brain, administer high-flow oxygen, and transport to a hyperbaric chamber. Correct Answer:
B
The venom of a black widow spider is toxic to the:
a) respiratory system.
b) cardiovascular system.
c) nervous system.
d) renal system. Correct Answer: C
A person's ability to shiver is lost when his or her body temperature falls below:
a) 92°F (33°C).
b) 94°F (34°C).
c) 95°F (35°C).
d) 90°F (32°C). Correct Answer: D
A 20-year-old male was pulled from cold water by his friends. The length of his submersion is not known
and was not witnessed. You perform a primary assessment and determine that the patient is apneic and
has a slow, weak pulse. You should:
a) suction his airway for 30 seconds, provide rescue breathing, keep him warm, and transport at once.
b) provide rescue breathing, remove wet clothing, immobilize his spine, keep him warm, and transport
carefully.
