New parents ask the nurse, "Why is it necessary for our baby to have the newborn blood test?" The nurse explains that the priority outcome of mandatory newborn screening for inborn errors of metabolism is
early identification of serious genetically transmitted metabolic diseases.
early identification of electrolyte imbalances.
appropriate community referral for affected infants.
parental education about raising a special needs child.
The Correct Answer is A
A. The primary purpose of newborn screening is to detect serious metabolic or genetic disorders early, such as phenylketonuria (PKU) or congenital hypothyroidism, so prompt treatment can prevent severe complications or death.
B. While electrolyte imbalances may be detected incidentally, screening is not designed for this purpose.
C. Referral to community resources may follow a positive result, but it is not the primary outcome; the focus is on early detection and treatment.
D. Parental education is important after diagnosis, but the priority goal of screening is to identify treatable conditions early, not primarily to educate on special needs care.
