Beta blocker ingestion in small children would MOST likely cause:

Explanation:
Beta-adrenergic signaling normally helps raise blood glucose when a child is fasting or stressed. Blocking those signals, especially beta-2 receptors in the liver, reduces glycogenolysis and gluconeogenesis, so a small child can quickly become hypoglycemic after beta-blocker ingestion. In young kids with limited glycogen stores, this effect is particularly pronounced, making acute hypoglycemia the most likely and dangerous presentation. Hypertension is unlikely because these drugs lower blood pressure, and hyperglycemia is less common with beta-blocker overdose. Hyperkalemia can occur but is not the most typical finding.
