A. hypercalcemia.
B. hypothermia.
C. hypokalemia.
D. hyponatremia. ANSW✅✅B. hypothermia.
The recommended first-line treatment for third-degree heart block associated with bradycardia and
hemodynamic compromise is:
A. an epinephrine infusion.
B. transcutaneous pacing.
C. a dopamine infusion.
D. atropine sulfate. ANSW✅✅B. transcutaneous pacing.
The second half of the T wave:
A. is the point of ventricular depolarization to which a defibrillator is synchronized to deliver
electrical energy.
B. is the strongest part of ventricular depolarization and is often the origin of dangerous ventricular
arrhythmias.
C. represents a state of absolute ventricular refractoriness in which another impulse cannot cause
depolarization.
D. represents a vulnerable period during which a strong impulse could cause depolarization,
resulting in a lethal arrhythmia. ANSW✅✅D. represents a vulnerable period during which a strong
impulse could cause depolarization, resulting in a lethal arrhythmia.
Torsade de pointes:

, B. is a lethal ventricular rhythm that is usually caused by ingestion or injection of CNS-depressant
drugs.

D. is generally less serious than monomorphic ventricular tachycardia and is usually not treated in
the field. ANSW✅✅A. is a variant of polymorphic ventricular tachycardia and is often caused by a
prolonged QT interval.
