Question

An 88-year-old female experienced a syncopal episode. She is now conscious, but complains of dizziness and generalized weakness, and her pulse is 170 beats/min and irregular. The EMT should recognize that this patient's syncope was MOST likely caused by:

A) an acute cardiac dysrhythmia.
B) increased parasympathetic tone.
C) widespread systemic vasodilation.
D) decreased sympathetic tone.

Answer 1

The 88-year-old female's syncope was most likely caused by an acute cardiac dysrhythmia.

Step-by-step explanation:

The syncope experienced by the patient is most likely caused by an acute cardiac dysrhythmia.

Based on the symptoms of dizziness, generalized weakness, and an irregular and rapid pulse rate of 170 beats/min, it is indicative of a cardiac issue. An acute cardiac dysrhythmia refers to an abnormal heart rhythm that can result in a sudden loss of consciousness (syncope).

It is important for the EMT to recognize this life-threatening condition promptly and initiate appropriate treatment measures such as cardiology consultation and potentially cardiopulmonary resuscitation (CPR) if necessary.
