Answer to Question 1

D
Feedback:
Oxygen saturation should be at least 94 on room air; 91 to 93 are below this threshold.

Answer to Question 2

C
Feedback:
Myelomeningocele is a congenital neural tube defect in which the vertebral spaces fail to close, allowing a herniation (bulging) of the spinal cord nerve fibers and meninges into a sac. Anencephaly is a congenital neurologic disorder in which part or all of the brain is missing. Hydrocephalus is the accumulation of excess of cerebrospinal fluid (CSF) in the ventricles and subarachnoid spaces of the brain. The newborn may also exhibit bulging fontanels and nervous irritability. Down syndrome is a genetic disorder often associated with mothers who give birth after age 40 . Physical and mental manifestations may range from mild to severe.
