The admission laboratory results indicate elevations in troponin I and creatine phosphokinase myoglobin isoenzyme (CK-MB) levels. What should the PN consider the most significant risk for this client on the second day of admission?

The lab results indicate myocardial damage, and the client is at risk for cardiac dysrhythmias.

The client is at risk for pulmonary embolism, and lifestyle modifications need to be implemented.

The client is at risk for recurrent long-term angina pain and subsequent myocardial infarction (MI).
