A nurse is contributing to the development of an in-service training about child maltreatment for a group of pediatric nurses. Which of the following findings should the nurse identify as a risk factor for child maltreatment?

A. The infant was born large for gestational age: Being large for gestational age is not recognized as a risk factor for child maltreatment. Risk factors are more often related to family dynamics, age, and social stressors rather than birth weight alone. B. The infant has otitis media: Otitis media, or a middle ear infection, is a common pediatric illness and is not itself a risk factor for maltreatment. It reflects normal childhood health issues rather than abuse or neglect. C. The infant is younger than 1 year of age: Infants under 1 year are particularly vulnerable to maltreatment because of their total dependence on caregivers and inability to communicate effectively. This age group is at the highest risk for serious injury from abuse. D. The infant's guardians are both over the age of 30: Parental age over 30 does not inherently increase the risk for child maltreatment. Other factors like substance abuse, history of being abused, and high stress levels are more closely linked to maltreatment risk.
