b. Falling asleep in the chair and refusing to eat lunch

ANS: A
TD manifests as abnormal movements of voluntary muscle groups after a prolonged period of dopamine blockade. Movements may affect any muscle group, but muscles of the face, mouth, tongue, and digits are commonly affected. Falling asleep is reflective of the sedative effect of these medications. Muscle rigidity and drooling reflect EPS caused from imbalance between dopamine and acetylcholine.
