Which complication should be included in teaching about repeated vomiting and laxative use?

• A. Electrolyte imbalance.
• B. Seizures.
• C. Overdose.
• D. Renal problems.

Answer: (A)

Electrolyte imbalance is the main complication to teach because repeated vomiting and laxative use directly disrupt body fluids and minerals. Vomiting removes stomach acids and electrolytes like chloride and potassium along with water, which can lead to dehydration and metabolic alkalosis, while ongoing laxative use adds to fluid and electrolyte loss, especially potassium. These combined losses set the stage for dangerous changes in heart rhythm, muscle function, and mental status. Seizures can occur if disturbances become severe, but electrolyte imbalance best captures the range of problems these behaviors can cause. Overdose or renal problems aren’t the central teaching focus for this specific pattern of behavior.
