Answer to Question 1

Ans:
C

Feedback:

A direct contusion of the brain at the site of external force is referred to as a coup injury. Contrecoup injury (answer choice D) is the rebound injury on the opposite side of the brain. Answer choice B relates to lacerations that are usually not caused by a direct blow to the head. However, depending on how hard the head was hit with a bat, a hematoma could form as the brain strikes the rough surface of the cranial vault.

Answer to Question 2

Ans:
A

Feedback:

Spina bifida occulta is characterized by incomplete closure of the axial groove around the ectodermal tube (neural tube). Protrusion of the spinal cord and meninges through the skin is associated with meningomyelocele. Insufficient development of the CNS, PNS, soma, or viscera is not considered a central characteristic of spina bifida occulta.
