Worksheet time: 5mins
The most appropriate position for a patient during NG tube insertion is:
Supine with head flat
Prone position
High Fowler’s position (sitting upright)
Trendelenburg position
The primary purpose of measuring the NG tube length before insertion is to:
Reduce patient discomfort
Ensure correct tube placement
Prevent nasal bleeding
Improve swallowing
The correct method to estimate the length of NG tube to be inserted is:
Nose → Ear → Xiphoid process
Mouth → Ear → Umbilicus
Nose → Chin → Sternum

Which lubricant is recommended for NG tube insertion?
Oil-based lubricant
Petroleum jelly
Optilube
Alcohol gel
During insertion, the patient is asked to swallow mainly to:
Reduce gag reflex
Open the esophagus
Ease tube passage into the stomach
All of the above
The best initial method to confirm NG tube placement at the bedside is:
Inject air and auscultate
Aspirate gastric contents and check pH
Observe patient coughing
Chest X-ray
A pH value of aspirate indicating correct gastric placement is usually:
> 8
6–8
1–5.5
Exactly 7
Which of the following is a contraindication for NG tube insertion?
Recent nasal surgery
Intestinal obstruction
Gastric ulcer
Diarrhea
A sign of incorrect placement into the respiratory tract is
Easy swallowing
Persistent coughing and respiratory distress
Gastric aspirate
Normal breathing
The gold standard for confirming NG tube placement is
Air insufflation test
pH testing
Radiographic confirmation (X-ray)
Visual inspection
