Final answer:
A concern for this patient is that atenolol (Tenormin) may mask signs and symptoms of hypoglycemia.
Step-by-step explanation:
For a patient recently diagnosed with type 2 diabetes and a history of MI, hypertension, and CAD, a concern would be that atenolol (Tenormin), one of the medications the patient is currently taking, may mask signs and symptoms of hypoglycemia. Atenolol is a beta-blocker that can reduce the symptoms that typically accompany low blood sugar levels, making it harder for the patient to recognize and treat hypoglycemia promptly. This can be dangerous as untreated hypoglycemia can lead to serious complications. Other medications the patient is taking, such as aspirin, do not directly contribute to this concern.
