below the level of the patient, allowing the solution to drain out of the stomach by

assessed carefully for abdominal distension. Repeat the procedure until the stomach
contents return clear, the entire amount of solution has been used, or otherwise
Assemble the necessary equipment.
Identify the patient and explain what is to be done.
