Answer to Question 1

ANS: D
Erb palsy (Erb-Duchenne paralysis) is caused by damage to the upper plexus and usually results from stretching or pulling away of the shoulder from the head. The Moro reflex is absent in a newborn with Erb palsy. The root and suck reflex are not affected. A grasp reflex is present in newborns because the finger and wrist movements remain normal.

Answer to Question 2

ANS: C
DMD is characterized by a waddling gait and lordosis. Gower sign is a characteristic way of rising from a squatting or sitting position on the floor. DMD is inherited as an X-linked recessive gene. Genetic counseling is recommended for parents, female siblings, maternal aunts, and their female offspring. Onset occurs usually between ages 3 and 5 years. DMD has a progressive and relentless loss of muscle function until death by respiratory or cardiac failure.
