Which of the following patients would MOST likely present with vague or unusual
symptoms of an acute myocardial infarction?
A) 55-year-old obese female
B) 66-year-old male with angina
C) 72-year-old female with diabetes
D) 75-year-old male with hypertension ---------CORRECT ANSWER-----------------C
Feedback :
Not all patients experiencing acute myocardial infarction (AMI) present with the
classic signs and symptoms one would expect. Middle-aged men often minimize
their symptoms and attribute their chest pain or discomfort to indigestion.
Some patients, however, do not experience any pain. In particular, elderly
women with diabetes may present with vague, unusual, or atypical symptoms
of AMI; their only presenting complaint may be fatigue or syncope. Do not rule
out a cardiac problem just because a patient is not experiencing chest pain,
pressure, or discomfort; this is especially true in elderly females with diabetes.
,Which of the following statements regarding the automated external defibrillator
(AED) is correct?
A) The AED should be applied to patients at risk for cardiac arrest.
B) AEDs will analyze the patient's rhythm while CPR is in progress.
C) The AED should not be used in patients with an implanted defibrillator.
D) AEDs can safely be used in infants and children less than 8 years of age. ---------
CORRECT ANSWER-----------------D
Feedback :
According to the 2015 guidelines for CPR and Emergency Cardiac Care (ECC), the
AED can safely be used in infants and children less than 8 years of age. Although
a manual defibrillator is preferred in infants, an AED can be used. When using
the AED in infants and children, you should use pediatric pads and a dose-
attenuating system (energy reducer); however, if these are not available, adult
AED pads should be used. The AED should be applied only to patients in cardiac
arrest; if a patient is at risk for cardiac arrest, have the AED ready but not
applied. The AED will not analyze the cardiac rhythm if the patient is moving (ie,
CPR is in progress). AEDs can be used in patients with an automated implanted
cardioverter/defibrillator (AICD) or implanted pacemaker; ensure that the pads
are at least 1 inch away from the implanted device.
Which of the following describes pulseless electrical activity (PEA)?
A) disorganized, chaotic quivering of the heart muscle that does not generate a
pulse
B) The presence of a palpable pulse in the absence of any electrical activity in the
heart
,C) A rapid cardiac rhythm that does not produce a pulse, but responds to
defibrillation
D) Any organized cardiac rhythm, slow or fast, that does not produce a palpable
pulse ---------CORRECT ANSWER-----------------D
Feedback :
Pulseless electrical activity (PEA) is a condition in which the heart produces
organized electrical activity (slow or fast), despite the absence of a palpable
pulse. A disorganized, chaotic quivering of the heart muscle that does not
generate a pulse is called ventricular fibrillation (V-Fib), and is treated with
defibrillation. Defibrillation is not indicated for patients with PEA; it is indicated
only for patients with V-Fib or pulseless ventricular tachycardia (V-Tach). If the
AED gives a no shock message and the patient is still pulseless, he or she is
either in asystole or PEA, neither of which is a shockable rhythm.
Which of the following statements regarding one-rescuer CPR is correct?
A) You should assess the patient for a pulse after 3 cycles of CPR.
B) A compression to ventilation ratio of 15:2 should be delivered.
C) Ventilations should be delivered over a period of 2 to 3 seconds.
D) The chest should be allowed to fully recoil after each compression. ---------
CORRECT ANSWER-----------------D
Feedback :
When performing CPR on any patient, you should allow the chest to fully recoil
after each compression; do not lean on the chest between compressions.
Incomplete chest recoil causes increased intrathoracic pressure, which may
, impair blood return to the heart. Assess the patient's pulse after every 5 cycles
(about 2 minutes) of CPR; take no longer than 5 to 10 seconds to do this. A
compression to ventilation ratio of 30:2 should be used during all adult and one-
rescuer CPR (adult, child, and infant), except for newborns. A compression to
ventilation ratio of 15:2 is used during two-rescuer infant and child CPR.
Ventilations should be delivered over a period of 1 second each, just enough to
produce visible chest rise.
How can you help maximize cardiac output during CPR?
A) Compress the chest at a rate of no more than 100/min
B) Ventilate the patient through an advanced airway device
C) Deliver rescue breaths until the chest expands widely
D) Allow the chest to fully recoil in between compressions ---------CORRECT
ANSWER-----------------D
Feedback :
Cardiac output is the amount of blood ejected from the left ventricle per
minute. Bearing in mind that even the best-performed CPR produces only a
fraction of what the patient's cardiac output would otherwise be, there are
several actions that you must take to help maximize this. Allowing the chest to
fully recoil in between compressions will help draw blood back to the heart; if
more blood returns to the heart, more blood can be pumped from the heart
with chest compressions. Do not lean on the patient's chest between
compressions. Delivering each rescue breath over a period of 1 second, just
enough to produce visible chest rise, will also help maximize cardiac output. If
ventilations are given too fast or too forcefully, intrathoracic pressure will
increase, resulting in a decrease in the amount of blood that returns to the
heart; as a result, cardiac output will decrease. Ventilations are delivered no
