Symptoms of Atenolol toxicity may include heart failure (CHF), AV block, and a sedative appearance, but not tachycardia.

Correct Answer: B

Rationale: Prednisone toxicity is not typically associated with hypotension; instead, it can lead to hypertension. Cataracts, psychosis, and acne are known side effects of Prednisone toxicity.
