The nurse has been ordered to perform gastric lavage on a patient. The nurse knows that which of these statements is correct regarding gastric lavage?
Gastric lavage should not be performed on an unconscious patient or a patient with an impaired gag reflex unless an endotracheal tube is placed first.
Patient positioning is not important when performing a gastric lavage.
The proper length of the nasogastric tube is found by measuring the distance from the nose to the earlobe and then to the mid sternal area.
It is not essential to confirm the correct placement of the nasogastric tube prior to administering the ordered solution if careful measurements were done prior to the placement of the tube.
