**Core Concept**
Gastric lavage, also known as stomach pumping, is a medical procedure used to remove fluid or semi-solid material from the stomach. It is typically performed after a patient has ingested a toxic substance or has experienced a gastrointestinal hemorrhage. However, its use is limited due to potential complications and contraindications.

**Why the Correct Answer is Right**
The correct answer is related to the contraindications of gastric lavage. Gastric lavage is contraindicated in patients with a full stomach, as it can lead to aspiration of stomach contents into the lungs, causing chemical pneumonitis or aspiration pneumonia. This is a significant risk in patients who have ingested corrosive substances, as it can cause severe lung damage. The procedure is also contraindicated in patients with a history of gastrointestinal bleeding, as it can worsen the bleeding.
