question 19 (1 point)
listen
neural tube defects:
almost always have an excellent prognosis without residual deficits.
are classified as spina bifida, meningocele, or myelomeningocele.
require aggressive treatment without surgical intervention.
are characterized by hyperactive reflexes and rapid muscle contractions.
question 20 (1 point)
listen
hirschsprung disease:
is diagnosed by a rectal biopsy revealing the absence of ganglion cells in the colorectal wall.
is characterized by obstruction and dilation of the colon.
is also called congenital aganglionic megacolon.
all of the above

Explanation:

For Question 19:

Neural tube defects often result in lifelong deficits, so the first option is incorrect. Surgical intervention is typically required, making the third option wrong. Hyperactive reflexes are not their defining feature, eliminating the fourth option. The main classifications of neural tube defects include spina bifida, meningocele, and myelomeningocele.

For Question 20:

Hirschsprung disease is formally known as congenital aganglionic megacolon. It causes colon obstruction and dilation due to missing ganglion cells in the colorectal wall, and diagnosis is confirmed via rectal biopsy showing this absence of ganglion cells. All listed statements are correct.

Answer:

Question 19: Are classified as spina bifida, meningocele, or myelomeningocele.
Question 20: All of the above
