In ACS, which of the following is not typically monitored?

• A. Chest X-ray
• B. Vital signs
• C. Serial ECG
• D. Troponin levels

Answer: (A)

In ACS, the focus of monitoring is on detecting rapid changes in a patient’s condition—especially rhythm, perfusion, and ongoing ischemia. Vital signs and continuous ECG are essential because they reveal instability, arrhythmias, or evolving ischemia that require immediate intervention. Serial troponin levels are tracked to confirm myocardial injury, gauge the extent of infarction, and help guide treatment decisions.

A chest X-ray, while useful on admission to assess conditions like pulmonary edema, pneumonia, pneumothorax, or other thoracic problems, is not part of the routine real-time monitoring used to track ACS progression. It’s an imaging study obtained as needed rather than continuously monitored, which is why it’s not typically considered part of the ongoing monitoring in ACS.
