Final answer:
The most concerning findings for a nurse regarding a child's development are the child not walking by twelve months, watching television excessively, and only drinking from a bottle.
Step-by-step explanation:
The three findings most concerning to a nurse when assessing the development of a child are: a. Child not walking, d. Watches television most of the day, and e. Drinks only from a bottle. These concerns are based on normative developmental milestones and potential negative health impacts. By twelve months, a child should typically be able to stand with assistance and possibly start walking; excessive television watching can contribute to a sedentary lifestyle and is often associated with childhood obesity; and continued exclusive use of a bottle beyond a year old can affect a child's nutritional intake and dental health.
