While transporting an elderly woman who was complaining of
nausea, vomiting, and weakness, she suddenly becomes
unresponsive. You should:
© 2025 Assignment Expert
A) analyze her cardiac rhythm with the AED.
B) open her airway and ensure that it is clear.
Guru01 - Stuvia
C) assess for signs of breathing and a pulse.
D) place her on her side in case she vomits. [ ANS: ] C
Feedback :
If a patient is found unresponsive or becomes unresponsive in your
presence, your first action should be to assess for breathing and a
pulse; this assessment can occur simultaneously and should take
no more than 10 seconds. If the patient is breathing adequately
and has a pulse, position her on her side and administer oxygen if
needed. If the patient has a pulse but is not breathing, open the
airway and provide rescue breathing. If the patient is not
breathing (or has agonal gasps) and does not have a pulse,
begin CPR (starting with chest compressions) and apply the AED
as soon as possible. If you are transporting a patient who
becomes unresponsive, pulseless, and apneic, you should begin
CPR and instruct your partner to stop the ambulance and prepare
the AED.
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:
A) cardiogenic shock.
B) hypovolemic shock.
C) acute septic shock.
D) pulmonary embolism. [ ANS: ] A
Feedback :

The patient in this scenario likely experienced an acute
myocardial infarction the day before. However, because he
refused medical care, the infarction has likely damaged a
Guru01 - Stuvia
significant portion of his heart, resulting in cardiogenic shock.
Cardiogenic shock occurs when the heart fails as a pump and
can no longer meet the metabolic needs of the body; it has a
very high mortality rate. The patient's labored breathing is likely
caused by pulmonary edema, which occurs when blood backs
up into the lungs because the heart cannot effectively pump.
There is no evidence of hypovolemia (ie, poor skin turgor) or sepsis
(ie, fever). A pulmonary embolism typically presents with an acute
onset of pleuritic (sharp) chest pain and difficulty breathing, and is
also commonly associated with cyanosis.
When an error occurs while using the AED, it is MOST often the
result of:
A) battery failure secondary to operator error.
B) malfunction of the microchip inside the AED.
C) misinterpretation of the patient's cardiac rhythm.
D) excess patient movement during the analyze phase. [ ANS: ] A

Feedback :
AEDs are highly sensitive and specific in recognizing shockable
rhythms (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 not fully charged. Some of the older AEDs, however, are not
equipped with this feature. Therefore, it is important to check the
© 2025 Assignment Expert
AED daily, exercise the battery as often as the manufacturer
recommends, and always have a spare, fully charged battery on
hand.
Guru01 - Stuvia
A middle-aged woman took three of her prescribed nitroglycerin
tablets after she began experiencing chest pain. She complains of
a bad headache and is still experiencing chest pain. You should
assume that:
A) her blood pressure is elevated.
B) she has ongoing cardiac ischemia.
C) her nitroglycerin is no longer potent.
D) her chest pain is not cardiac related. [ ANS: ] B
Feedback :
A headache and/or a bitter taste under the tongue are common
side effects of nitroglycerin (NTG) that many patients experience.
If the patient does not experience these side effects, the NTG may
have lost its potency. However, if a patient with chest pain takes
NTG and experiences these side effects, but still has chest pain,
you should assume that his or her pain is the result of cardiac
ischemia, a relative deprivation of oxygen to the heart. NTG is a

vasodilator drug; therefore, it would lower her blood pressure, not
raise it. Any patient with nontraumatic chest pain or pressure
should be assumed to be experiencing cardiac ischemia,
especially if the pain or pressure is not relieved with NTG.
In addition to chest pain or discomfort, a patient experiencing an
acute coronary syndrome would MOST likely present with:
A) ashen skin color, diaphoresis, and anxiety.
B) severe projectile vomiting and flushed skin.
C) irregular breathing and low blood pressure.

D) profound cyanosis, dry skin, and a headache. [ ANS: ] A
Feedback :
Guru01 - Stuvia
Chest pain, pressure, or discomfort is the most common symptom
of acute coronary syndrome (ACS; eg, unstable angina, acute
myocardial infarction); it occurs in approximately 80% of cases.
Patients with ACS are usually anxious and may have a feeling of
impending doom. Nausea and vomiting are common complaints;
however, projectile vomiting, which is typically associated with
increased intracranial pressure, is uncommon. The skin is often
ashen gray and clammy (diaphoretic) because of poor cardiac
output and decreased perfusion. Less commonly, the patient's skin
is cyanotic. Respirations are usually unlabored unless the patient
has congestive heart failure, in which case respirations are rapid
and labored; irregular breathing, however, is not common. Blood
pressure may fall as a result of decreased cardiac output;
however, most patients will have a normal or elevated blood
pressure. If the patient complains of a headache, it is usually a
side effect of the nitroglycerin he or she took before your arrival;
ACS itself usually does not cause a headache.
