A 58-year-old man is found unresponsive by his wife. According to his wife, he was
complaining of a "dull ache" in his chest the day before, but refused to allow her to call
911. His blood pressure is 70/50 mm Hg, his pulse is 120 beats/min and weak, and his
respirations are 28 breaths/min and labored. Further assessment reveals that his skin is
cool, pale, and clammy. You should suspect:

skin signs or any other indication of reduced blood volume
A 65-year-old woman complains of severe chest pain that radiates to her back, in
between her shoulder blades. She tells you that this is the most severe pain that she
has ever experienced, and that it has been intense since it began. Her past medical
history includes hypertension. When you palpate her radial pulses, you note that they
are unequal in strength. What should you suspect? - ANSWER Acute aortic dissection
which causes severe pain (often most pain experienced by patient) which- unlike a MI-
is maximum pain from the start. Hyper tension is also a risk factor
why does nitroglycerine cause headaches - ANSWER vasodilation leads to increased
cerebral blood flow
Your partner has applied the AED to a cardiac arrest patient and has received a shock
advised message. While the AED is charging, you should:
, A) continue chest compressions until your partner tells you to stand clear.
B) perform rescue breathing only until the AED is charged and ready to shock.
C) cease all contact with the patient until the AED has delivered the shock.
D) retrieve the airway equipment and prepare to ventilate the patient. - ANSWER A
Your assessment of a middle-aged female with chest pressure reveals that she is
confused, is diaphoretic, and has a blood pressure of 70/50 mm Hg. In caring for this
patient, it is MOST important for you to:
A) request an ALS unit to respond to the scene.
B) assist her with her nitroglycerin if she has any.
C) reassess her vital signs at least every 5 minutes.
D) prepare for immediate transport to the hospital. - ANSWER D

B) left ventricle contracts.
C) aortic valve opens.
D) right ventricle contracts. - ANSWER A) this happens during systole which coincides
with aortic valve closing

The energy setting for a biphasic AED:
A) is typically 360 joules.
B) is manufacturer specific.
C) must be manually set by the EMT.
D) increases by 50 joules with each shock. - ANSWER B (usually 120-200) and
increase with each shock is manufacturer dependent
A patient who is experiencing an acute myocardial infarction:
A) most often describes his or her chest pain as being sharp or tearing.
B) has chest pain or discomfort that does not change with each breath.
C) often experiences relief of his or her chest pain after taking nitroglycerin.

syncopal episode - ANSWER fainting spell
An 88-year-old female experienced a syncopal episode. She is now conscious, but
complains of dizziness and generalized weakness, and her pulse is 170 beats/min and
irregular. The EMT should recognize that this patient's syncope was MOST likely
caused by: - ANSWER drop in blood pressure second to reduced ventricular filling time
caused by tachycardia from an ACUTE CARDIAC DYSRHYTHMIA
