The RN notes the hands and feet of a newborn aged 3 hours appear blue. Which of the following is true of acrocyanosis?

A. This finding indicates atrial septal defect (ASD): While congenital heart defects can cause cyanosis, acrocyanosis is typically limited to the hands and feet and does not indicate a structural cardiac defect in a healthy newborn. It is distinguished from central cyanosis, which involves the lips, tongue, and mucous membranes. B. This is a normal finding up to 48 hours of life: Acrocyanosis is a common, benign condition in newborns caused by immature peripheral circulation and vasomotor instability. It usually appears within the first hours after birth and can persist up to 48 hours, especially in response to cold stress, and resolves as circulation stabilizes. C. CPR must be initiated immediately: Acrocyanosis alone in an otherwise stable newborn does not require resuscitation. CPR is only indicated if there are signs of central cyanosis, apnea, bradycardia, or other indicators of cardiopulmonary compromise. D. This is a normal finding up to 1 year of life: Persistent acrocyanosis beyond the first 48 hours is abnormal and may indicate underlying cardiovascular or respiratory issues. It is not considered normal beyond the neonatal period.
