Question 14 - Physiological Adaptation Practice Test for the NCLEX-RN Exam

Patient positioning is not important when performing a gastric lavage.

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.

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.

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.
