A 43 year-old male is lying in the rain after being struck by lightening. Upon assessment you
determine he is unresponsive, pulseless, and apenic. You begin CPR as you wait for the AED to
arrive. Which of the following is the appropriate action to take when the AED arrives?
a. Attach the AED immediately and deliver a shock to avoid further delay
b. Do not use an AED on this patient because he was struck by lightening and it is
contraindicated
c. Attach the AED after the patient is moved from the rain and dry
d. Attach the AED but do not shock
Attach the AED after the patient is moved from the rain and dry
You want to make sure the patient is dry before attaching the AED and delivering a shock. The
rain or any wetness can interfere with the pad stickiness and the electric conduction from the
device.

,You are performing CPR on a patient that has a stoma. You quickly realize air is leaking from his
nose and mouth. You should...
a. Suction the stoma
b. Provide ventilations with less pressure
c. Seal his nose and mouth
d. It is normal to happen patients with stomas
Seal his nose and mouth
If a patient has a stoma, you must provide ventilations through the stoma. If the air leaks
through their mouth and/or nose, you can seal them in order to provide more effective
ventilations and CPR.
You arrive to a scene of a man lying unconscious on the ground. You do not know the
mechanism of injury, but notice no visible signs of trauma. What should you ALWAYS assume?
a. He is having a diabetic emergency
b. He had a myocardial infarction
c. He is in cardiac arrest
d. He has a spinal injury
He has a spinal injury
When the mechanism of injury is unknown, always assume the patient has a spinal injury and
take cervical spine precautions, as this is the one thing we cannot completely confirm
prehospital.
You arrive to a home fire. The patient is rescued from the home and has circumferential burns
to his legs and feet causing increased swelling and blisters. He also has soot marks around his
mouth. The patient screams he is in 10/10 pain. What is the next best step?
2
,a. Pop the blisters before they get bigger to decrease severity
b. Apply ice packs to the burns immediately to reduce burning
c. Apply burn ointment and wrap in sterile dressing
d. Assess the airway and administer oxygen with non-rebreather
Assess the airway and administer oxygen with non-rebreather
This is the only appropriate choice. You do not want to pop the blisters, apply ice packs, or burn
ointment to the burns as these will all make it worse.
Which of the following organs in the left upper quadrant is MOST likely to be injured?
a. Liver
b. Spleen
c. Pancreas
d. Appendix
Spleen
The spleen is a large organ in the left upper quadrant that is the most likely to be injured.
Although the pancreas also partly is in the left upper quadrant, it hides behind the stomach and
less likely to be injured.
You are on scene of a motorcycle accident. The patient was not wearing a helmet. The patient
is responding to painful stimuli and keeps complaining of a "killer headache". His vital signs are
as follows: BP 176/94, HR 48, RR 8 breaths per minute. Soon after, he begins to vomit. What do
you suspect?
a. Shock
b. Increased intracranial pressure
c. Stroke

, d. Severe migraine
Increased intracranial pressure
The increased blood pressure with low heart rate and low respiratory rate are some late signs
of increased ICP. Headache and vomiting is also a common signs of increased ICP due to brain
swelling.
You arrive on scene to a 36 year-old female who has fallen off a 10 foot ladder. She is lying
supine on the ground and is unresponsive. You notice she has an open left femur fracture. You
can palpate a weak, carotid pulse and notice she has irregular respirations. What is the next
best step?
a. Apply C-collar since there could be a possible spinal injury
b. Control source of bleeding
c. Administer ventilations with bag-valve mask
d. Log roll onto backboard and rapid transport
Control source of bleeding
Remember we always want to treat life threats first. Since the patient has an open fracture of
the femur, a place where there is a large source of blood, we want to control the bleeding here
to prevent hypoperfusion and/or hypovolemic shock.
You are called to a 55 year old male on the shoulder of a major intersection. He fell off his
