Nancy Caroline’s Emergency Care in the Streets, 9th
Edition TEST BANK by Nancy Caroline
When managing cardiac arrest, the appropriate dosing regimen for epinephrine is: -
ANSWER:1mg of a 1:10,000 solution every 3-5 minutes
Premature ventricle complexes: - ANSWER:originate from a different pacemaker site
percutaneous coronary interventions involve: - ANSWER:a. recanalizing a blocked
coronary artery by passing a balloon or stent through a catheter via a peripheral
artery.
A patient in cardiogenic shock without cardiac arrhythmias will benefit MOST from: -
ANSWER:rapid transport to an appropriate hospital
A 70-year-old male presents with pain in his legs while walking. Within a few minutes
of sitting down, however, his symptoms resolve. What should you expect? -
ANSWER:peripheral arterial disease
Once an advanced airway device has been inserted into a cardiac arrest patient: -
ANSWER:ventilations are delivered at a rate of 10 breaths/min
Cardiac arrhythmias following an acute myocardial infarction: - ANSWER:tend to
originate from ischemic areas around the infarction
Takotsubo cardiomyopathy is MOST often associated with: - ANSWER:emotional
stress
The process of aortic dissention begins when: - ANSWER:the intimal layer of the
aortic wall is torn
An early complex that breaks the regularity of the underlying rhythm, and is
characterized by a narrow QRS complex and an upright P wave that differs in shape
and size from the P waves of the other complexes, MOST accurately describes a/an: -
ANSWER:premature atrial complex
An accelerated idioventricular rhythm is characterized by all of the following,
EXCEPT: - ANSWER:Irregular R-R intervals and a rate less than 40 beats/min
If the heart's secondary pacemaker becomes ischemic and fails to initiate an
electrical impulse: - ANSWER:You should expect to see a heart rate slower than 40
beats/min
An electrical wave moving in the direction of a positive electrode will: -
ANSWER:Cause a positive deflection on the ECG
, In sinus bradycardia, the: - ANSWER:pacemaker is in the SA node
Which of the following would MOST likely cause bradycardia? - ANSWER:beta-
blocker use
Unlike an idioventricular rhythm, an agonal rhythm: - ANSWER:does not produce a
pulse
After delivering a shock to a patient in pulseless ventricular tachycardia, you should:
- ANSWER:resume CPR
Junctional escape rhythms are characterized by: - ANSWER:a ventricular rate of 40-
60 beats/min
Which electrolyte maintains the depolarization phase? - ANSWER:calcium
A demand pacemaker: - ANSWER:generates pacing impulses only when it senses that
the heart's natural pacemaker has fallen below a preset rate.
A second-degree heart block, Mobitz type 1, occurs when: - ANSWER:each
successive impulse is progressively delayed until 1 impulse is blocked from entering
the ventricles.
Which leads provides the best view of the anterolateral wall of the left ventricle? -
ANSWER:v4-v6
When does a second-degree heart block occur? - ANSWER:Occurs when an impulse
reaching the AV node is occasionally prevented from proceeding to the ventricles
and causing a QRS complex
What is torsade de pointes? - ANSWER:a variant of polymorphic ventricular
tachycardia and is often caused by prolonged QT interval
What are characteristics of multifocal atrial tachycardia? - ANSWER:.11 QRS, variable
PR intervals, P waves differ, nonvisible P waves with rapid ventricular rate
Ventricular fibrillation occurs when? - ANSWER:many different cells in the heart
depolarize independently rather than in response to an impulse from the SA node.
Electrical capture during transcutaneous cardiac pacing is characterized by: -
ANSWER:a pacemaker spike followed by a wide QRS complex
On a 12-lead ECG, extreme right axis deviation is characterized by: - ANSWER:a
negative QRS in Lead I and a negative QRS in lead aVF
