Based on EKG results showing ST segment depression, which action is NOT a priority medical decision?

1. Prescribe metoprolol (Lopressor) 12.5mg PO BID.

2. Prescribe aspirin 81mg PO daily.

3. Refer to cardiology for angiography.

4. Check for thyroid dysfunction.

The correct answer is: Check for thyroid dysfunction.

The presence of ST segment depression on an EKG typically indicates myocardial ischemia, which is a critical condition that requires prompt assessment and intervention. In this context, checking for thyroid dysfunction is not a priority medical decision compared to options that directly address the acute cardiovascular concerns suggested by the EKG findings. The actions related to prescribing metoprolol, aspirin, and referring the patient to cardiology for further evaluation all focus on the immediate management of potential cardiac events. Metoprolol, a beta-blocker, is often used to manage heart rate and reduce myocardial oxygen demand, which is essential in someone presenting with signs of ischemia. Aspirin is critical for its antiplatelet properties, reducing the risk of thrombus formation in a patient potentially experiencing coronary artery disease. Referring to cardiology for angiography allows for further investigation into the blood flow and potential blockages in the coronary arteries, which is urgent given the patient's condition. In contrast, checking for thyroid dysfunction, while important in a comprehensive assessment, does not address the immediate cardiac risks associated with ST segment depression and can often lead to delays in necessary treatment. This makes it a non-priority action in the acute setting presented by the EKG results.
