Sudden cardiac arrest in the adult population MOST often is the
result of:
A) myocardial infarction.
B) respiratory failure.
C) a cardiac dysrhythmia.
D) accidental electrocution.
Answer- C
Feedback:
The most common cause of sudden cardiac arrest (SCA) in the
adult population is a cardiac dysrhythmia--usually ventricular
fibrillation. This fact underscores the importance of early
defibrillation to shock the heart back into a perusing rhythm.
Evidence has shown that SCA--again, most often the result of an
arrhythmia--occurs in up to 40% of patients experiencing an
acute myocardial infarction (AMI). The risk of SCA is highest
within the first few hours following the onset of an AMI.
,Respiratory failure is the most common cause of cardiac arrest
in children, not adults. Children generally have healthy hearts
and rarely experience cardiac arrest due to a primary cardiac
event.
Which of the following is the BEST indicator of cardiac output?
A) Pulse rate and quality
B) Systolic blood pressure
C) Quality of the respirations
D) Condition and color of the skin
Answer- A
Feedback:
Cardiac output is the amount of blood ejected from the
ventricles each minute. To best obtain an indication of cardiac
output, you should assess the rate and quality of the pulse. A
rapid, bounding pulse indicates increased cardiac output,
whereas a weak or "thread" pulse indicates a decreased cardiac
output. Changes in pulse quality (strength) will likely be
detected before a drop in systolic blood pressure.
,When assessing a patient who has stroke-like symptoms, you
should recall that:
A) the majority strokes are caused by a ruptured cerebral artery.
B) the patient may be unable to communicate, but can often
understand.
C) right-sided weakness indicates a stroke in the right cerebral
hemisphere.
D) fibrinolytic therapy must be given within 6 hours following
the stroke.
Answer- B
Feedback:
Some patients who have had a stroke may be unable to
communicate (expressive aphasia), but they can often
understand what is being said around them; be aware of this
possibility. Approximately 80 percent of all strokes are caused
by an occluded cerebral artery (ischemic stroke); strokes caused
by a ruptured cerebral artery (hemorrhagic stroke) are less
common. Because the left side of the brain controls the right
side of the body, and vice versa, right-sided weakness
(hemiparesis) indicates a stroke in the left cerebral hemisphere.
Some patients who have had a stroke may benefit from
fibrinolytic (clot-buster) therapy; however, to be most effective,
, this treatment must be given within the first 3 hours following
the onset of the stroke.
Which of the following is the MOST detrimental effect that
tachycardia can have on a patient experiencing a cardiac
problem?
A) Increased blood pressure
B) Increased oxygen demand
C) Increased stress and anxiety
D) Decreased cardiac functioning
B
Feedback:
As the heart beats faster, it consumes and demands more
oxygen. Tachycardia can be extremely detrimental to the patient
with a compromised heart that is already deprived of oxygen.
Keeping the patient calm cannot be overemphasized. The more
stressed and anxious the patient gets, the faster his or her heart
will beat.
In most people, the inferior aspect of the left ventricle receives
its blood supply from the:
