Quick, jerky, grossly uncoordinated, irregular movements that may disappear on relaxation are called choreiform movements. Twitching is defined as spasmodic movements of short duration. Spasticity is the prolonged and steady contraction of a muscle characterized by clonus (alternating relaxation and contraction of the muscle) and exaggerated reflexes. Associated movements are the voluntary movement of one muscle accompanied by the involuntary movement of another muscle.

In caring for a 6-year-old who entered the emergency center for treatment of a broken arm, the nurse noted that the child had multiple bruises on his trunk and legs
When questioned, the child said his father hit him and broke his arm so that the child would remember to be good. What should the nurse do? 1. Chart that the child is a victim of child abuse, so that there is a record of the abuse should such behavior reoccur. 2. Downplay the child's comments, because children often exaggerate. 3. Do nothing, because the nurse cannot prove the child was really abused, and saying anything could open the institution to a possible defamation lawsuit. 4. Report the incident immediately to the nursing supervisor or physician so that the incident will be reported to the proper authorities.
