Question

The nurse is monitoring the ECG of a patient admitted with ACS. Which of the following ECG characteristics would be most suggestive of ischemia?

A) Sinus rhythm with a pathologic Q wave
B) Sinus thythm with an elevated ST segment
C) Sinus rhythm with a depressed ST segment
D) Sinus rhythm with premature artial contractions

Answer 1

A depressed ST segment on an ECG would be most suggestive of ischemia in a patient with ACS.

Step-by-step explanation:

The presence of a depressed ST segment on an ECG would be most suggestive of ischemia in a patient admitted with ACS (Acute Coronary Syndrome).

In patients with ischemia, the ST segment is typically depressed below the baseline. This indicates that there is inadequate oxygen supply to the myocardium, leading to the abnormal electrical activity.

Other ECG characteristics that may indicate ischemia include ST segment elevation, T wave inversion, and the presence of pathological Q waves.
