The nurse is examining a 10-month-old boy who was born 10 weeks early. Which finding is cause for concern?

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. “This is a vasomotor response caused by cooling or warming": While vasomotor responses can cause changes in skin color due to temperature changes, acrocyanosis specifically refers to blue discoloration of the hands and feet due to reduced peripheral circulation, not necessarily due to temperature changes.

B. “This is normal her circulatory system will take a few days to adjust”: While it's true that newborns may have transient circulatory changes as their circulatory system adapts after birth, acrocyanosis specifically refers to a benign condition characterized by persistent blue discoloration of the extremities unrelated to circulatory adjustments.

C. "Let's watch her carefully to make sure she does not have a circulatory problem": While it's important to monitor infants for any signs of circulatory problems, acrocyanosis is typically a

benign and self-limiting condition that does not require intervention unless accompanied by other concerning symptoms.

D. "Your daughter has acrocyanosis; this is causing her blue hands and feet.”: This response provides an accurate explanation for the blue discoloration of the infant's hands and feet. Acrocyanosis is a common and benign condition in newborns characterized by blue discoloration of the extremities due to peripheral vasoconstriction, which gradually resolves over the first few days to weeks of life.
