The use of cocaine is higher in which group of people?

A. Sexual abuse: While sexual abuse can cause physical and emotional symptoms, the combination of unexplained injuries and fussiness/irritability is more suggestive of physical trauma.
B. Neglect: Neglect involves failure to provide for the child's basic needs, which can lead to developmental issues, but is less likely to cause unexplained injuries.
C. Munchausen syndrome by proxy: Munchausen syndrome by proxy involves a caregiver fabricating or inducing illness in a child for attention. It can cause unexplained injuries, but the focus is more on medical symptoms.
D. Shaken baby syndrome: Shaken baby syndrome results from violently shaking an infant, leading to physical injuries, irritability, and fussiness. It fits the description of unexplained injuries and behavioral changes.

A. Delivery at full term: Abuse and stress during pregnancy are associated with preterm birth rather than full-term delivery.
B. Low birth-weight infant: Abuse during pregnancy can lead to poor prenatal care, increased stress, and health complications, all of which contribute to low birth weight in infants.
C. Adequate prenatal care: Abused pregnant women often receive inadequate prenatal care due to controlling behaviors of the abuser or fear of seeking help.
D. Mother openly seeks help: Victims of abuse often do not openly seek help due to fear, shame, or control by the abuser.
