Show Hint
Transpyloric tubes use the longer NEMU rule: nose to ear to mid-umbilicus.

- Nose to Umbilicus
- Ear Lobe to Umbilicus
- Nose to Knee Joint
- Ear Lobe to Knee Joint
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Compare the two common tube-sizing rules.
NEX (nose to ear to xiphoid) sizes a tube meant to stop in the stomach. NEMU (nose to ear to mid-umbilicus) sizes a tube meant to pass beyond the stomach into the small bowel, which is what transpyloric feeding needs.
Step 2: Match the question to the right rule.
Since the question asks about transpyloric feeding, meaning the tube tip sits past the pylorus, the longer NEMU measurement applies, not the shorter gastric one.
Step 3: Read off the landmarks in NEMU.
The measurement starts at the nose, runs to the ear, then down to the umbilicus. In short form this is described as nose to umbilicus.
Step 4: Eliminate the knee-based options.
The knee joint is never used as a landmark in feeding tube sizing in infants, so any option built around it can be dropped right away.
Step 5: Conclude.
\[ \boxed{\text{Nose to Umbilicus}} \]
