Gastric gavage needle length is determined by measuring from which anatomical landmark?

• A. From the corner of the mouth to the sternum (at the xiphoid process)
• B. From the chin to the stomach (at the top portion)
• C. From the nose to the top of the sternum
• D. From the start of the esophagus to the stomach

Answer: (A)

Gastric gavage needle length is set by estimating how far the needle must travel from the mouth to the stomach, using external anatomy as a guide. The corner of the mouth to the sternum at the xiphoid process lines up with where the stomach sits in the abdomen, so this measurement gives a reliable insertion depth that puts the needle tip into the stomach rather than stopping too short or going too far. Using a landmark like the chin to a vague part of the stomach or the nose to the sternum doesn’t correspond as consistently to the stomach’s location, and measuring from the start of the esophagus to the stomach isn’t practical or dependable for external measurement. So, measuring from the corner of the mouth to the xiphoid process provides the appropriate depth for safe, effective gavage.
