When administering Tenormin what should you monitor?

When administering Tenormin (atenolol), it is essential to monitor the patient's heart rate and blood pressure regularly, as the medication can cause bradycardia and hypotension. Additionally, assess for signs of worsening heart failure, such as increased shortness of breath or edema. Monitor for any potential side effects, including dizziness or fatigue, and evaluate renal function, especially in patients with pre-existing kidney issues.
