|| || || || || || || ||
You are assessing a 33-year-old male who complains of severe abdominal pain, weakness, and
|| || || || || || || || || || || || || ||
nausea. He tells you that he was gathering wood to build a fire when he felt a sudden, sharp pain

After being stung on the leg by a jellyfish, a man complains of severe pain to his leg, dizziness,
|| || || || || || || || || || || || || || || || || || ||
and difficulty breathing. He has a red rash covering his trunk and his blood pressure is 90/50 mm
|| || || || || || || || || || || || || || || || || ||
Hg. The EMT should: - ✔✔administer oxygen and epinephrine and prepare for rapid transport.
|| || || || || || || || || || || || ||

swimmer hyperventilates prior to entering the water. || || || || || ||
Which of the following statements regarding drowning is correct? - ✔✔Laryngospasm following
|| || || || || || || || || || || ||
submersion in water makes rescue breathing difficult. || || || || || ||

|| || || || || || || || || || || || || || || || ||
damage.
A dysbarism injury refers to the signs and symptoms related to changes in: - ✔✔barometric
|| || || || || || || || || || || || || || ||
pressure.
A patient with a core body temperature of 95°F (35°C) will MOST likely experience: - ✔✔rapid
|| || || || || || || || || || || || || || || ||
breathing.
The diving reflex may allow a person to survive extended periods of submersion in cold water
|| || || || || || || || || || || || || || || ||
secondary to: - ✔✔bradycardia and a slowing of the metabolic rate.
|| || || || || || || || || ||

The transfer of heat to circulating air, such as when cool air moves across the body's surface, is
|| || || || || || || || || || || || || || || || || ||
called: - ✔✔convection || ||

|| || || || || || || || || || || || || || || || ||
pale. You should: - ✔✔move him into the cooled ambulance.

|| || || || || || || || || || || || || || ||
rate.

|| || || || || || || || || || || || ||
You are dispatched to a residence for a young female who is sick. The patient complains of a rash

|| || || || || || || || || || || || || || || || ||
suspect: - ✔✔Lyme disease. || || ||
