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

689. Surfactant is produced
a.within the
endoplasmic reticulum of type 2 pneumocytes
b. within the golgi body of type 2 pneumocytes
c. within
the endoplasmic reticulum of type 1 pneumocytes
d. within
the golgi body of type 1 pneumocytes
e. within the mitochondria of type 2 pneumocytes
