A nurse is teaching a group of healthcare providers about recognizing cardiac arrest. Which clinical finding is the most reliable indicator of cardiac arrest?
"Absence of a pulse"
"Irregular breathing pattern"
"Cyanosis of the lips and fingertips"
"Sudden loss of consciousness"
The Correct Answer is A
A) Correct. The absence of a pulse is the most reliable indicator of cardiac arrest. In cardiac arrest, the heart is no longer pumping effectively, leading to the absence of a palpable pulse.
B) Incorrect. An irregular breathing pattern may be observed in various medical conditions, including respiratory distress, but it is not as definitive as the absence of a pulse in indicating cardiac arrest.
C) Incorrect. Cyanosis of the lips and fingertips can occur in various situations, such as respiratory failure or decreased oxygenation, but it is not specific to cardiac arrest.
D) Incorrect. Sudden loss of consciousness can occur due to various reasons, including seizures or fainting, and is not solely indicative of cardiac arrest.
