The nurse performing a health history on a child asks the parents if their child has experienced increased appetite or thirst. What body system is the nurse assessing with this question?

A. Obtain a detailed history.

Obtaining a detailed history is essential to understand the circumstances surrounding the bruises, including how they occurred, where they are located, and whether there is a plausible

explanation for them. This information helps determine whether the bruises are due to accidental injury or potential abuse.

B. Report the suspected abuse to the authorities.

While reporting suspected abuse may ultimately be necessary if there are concerns about the origin of the bruises, obtaining a detailed history is the initial step to gather information and assess the situation before making a report.

C. Ask a psychiatrist to talk with the parents.

Involving a psychiatrist may be appropriate in cases where there are concerns about the child's mental health or the family dynamics, but it may not address the immediate concern of the bruises without first obtaining a detailed history.

D. Separate the child from the parents.

Separating the child from the parents should not be the first action taken without sufficient evidence or reason to believe that the child is in imminent danger. Gathering information through a detailed history is essential before considering such a drastic measure.

A. Has a fear of strangers: Fear of strangers typically emerges around 6 to 9 months of age as part of normal social development. While it indicates cognitive and emotional growth, it does not necessarily warrant further evaluation unless it is excessive or accompanied by other concerning behaviors.

B. Uses a unidextrous grasp: By 7 months, infants typically develop a more refined pincer grasp, where they can pick up small objects using the thumb and forefinger (bidextrous grasp). A unidextrous grasp (using only one hand) may suggest a delay in fine motor development and could warrant further evaluation by a healthcare provider.

C. Babbles one-syllable sounds: Babbling is a typical milestone in language development for

infants around 6 to 9 months of age. One-syllable babbling is expected at this stage and does not necessarily indicate a need for further evaluation.

D. Shows preferences towards foods: Developing food preferences is part of normal feeding behavior for infants. While it is important to ensure a balanced diet, showing preferences towards certain foods is not typically a cause for concern at this age.
