Paramedic Chapter 17 Exam Questions
and Answers All Correct
A middle-aged man in ventricular fibrillation has been refractory to several biphasic
defibrillations, well-coordinated CPR, adequately performed ventilations, and two doses
of epinephrine. What should you do next? - Answer-Administer 300 mg of amiodarone
via rapid IV push.
An early complex that breaks the regularity of the underlying rhythm and that 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(n): -
Answer-premature atrial complex.
An unresponsive, pulseless, apneic patient presents with ventricular tachycardia on the
cardiac monitor. After defibrillating the patient, you should: - Answer-resume CPR and
reassess the patient after 2 minutes.
A pathologic Q wave: - Answer-is wider than 0.04 seconds and indicates that a
myocardial infarction occurred in the past.
A regular rhythm with inverted P waves before each QRS complex, a ventricular rate of
70 beats/min, narrow QRS complexes, and a PR interval of 0.16 seconds should be
interpreted as a(n): - Answer-accelerated junctional rhythm
A wandering atrial pacemaker: - Answer-may have variable PR intervals.
Common causes of cardiac arrest include all of the following, EXCEPT: - Answer-
hyperglycemia
Electrical capture during transcutaneous cardiac pacing is characterized by: - Answer-a
pacemaker spike followed by a wide QRS complex.
If an impulse generated by the AV node begins moving upward through the atria before
the other part of it enters the ventricles: - Answer-an inverted P wave will appear before
the QRS complex.
If the R-R interval spans more than ____ large boxes on the ECG graph paper, the
heart rate is less than 60/min. - Answer-5
, Leads V1 to V3 allow you to view the ________ wall of the left ventricle. - Answer-
anteroseptal
Nitroglycerin is contraindicated for patients: - Answer-with suspected right ventricular
infarction.
Non-ST Elevation Myocardial Infarction (NSTEMI): - Answer-is not generally treated
with cardiac catheterization.
Normal sinus rhythm is characterized by all of the following, EXCEPT: - Answer-QRS
complexes that are up to 140 milliseconds.
Once an advanced airway device has been inserted into a cardiac arrest patient: -
Answer-ventilations are delivered at a rate of 10 breaths/min.
On the 12-lead ECG, extreme right axis deviation is characterized by: - Answer-a
negative QRS in lead I and a negative QRS in lead aVF.
On the ECG strip, a third-degree AV block usually appears as a: - Answer-slow, wide
QRS complex rhythm with inconsistent PR intervals.
Patients with Wolff-Parkinson-White syndrome: - Answer-have an accessory pathway
that bypasses the AV node and causes early ventricular depolarization.
The brief pause between the P wave and QRS complex represents: - Answer-a
momentary conduction delay at the AV node.
The circumflex branch of the left coronary artery supplies the _________ wall of the left
ventricle. - Answer-lateral (left) wall
The door-to-balloon time for a patient with an ST elevation myocardial infarction is ___
minutes or less. - Answer-90
The P wave represents: - Answer-atrial depolarization
The QRS in lead I is a positive deflection and the QRS in lead aVF is a negative
deflection. This indicates: - Answer-left axis deviation
Torsade de pointes: - Answer-is a variant of polymorphic ventricular tachycardia and is
often caused by a prolonged QT interval.
When administering aspirin to a patient with an acute coronary syndrome, you should: -
Answer-have him or her chew and swallow 160 to 325 mg of baby aspirin.
When performing CPR on an adult patient in cardiac arrest, it is important to: - Answer-
allow the chest to fully recoil between compressions.
