mcq frcr and pg


687.All are true regarding radiological evaluation of tubes and lines except
a. Optimal positioning for an endotracheal tube (ETT) is approximately 1–1.5 cm above the carina
b. The umbilical arterial line  lies just lateral to the right  side of the spine.
c.The tip of umbilical arterial line should ideally lie between T6 and T10 to avoid the spinal artery
d. The tip of umbilical arterial line should ideally lie at L3–L5 below the level of the bowel and renal arteries
e. The umbilical vein catheter  tip lies above the liver 


687.-----b
The umbilical arterial line initially courses caudally through the internal and common iliac arteries to enter the aorta, and lies just lateral to the left side of the spine. The umbilical vein catheter courses directly cephalad on the right side of the abdomen and enters the left portal vein, at which point it may enter the ductus venosus and then the inferior vena cava. Radiographs should confirm that the tip lies above the liver and has not passed into a tributary vein (CHAPTER 64 – The Neonatal and Paediatric Chest  ,Adam: Grainger & Allison's Diagnostic Radiology, 5th ed)

a.within the endoplasmic reticulum of type 2 pneumocytes
b.  within the golgi body  of type 2 pneumocytes

d. within the golgi body  of type 1 pneumocytes

e. within the mitochondria  of type 2 pneumocytes
