The newborn diagnosed with phenylketonuria (PKU) will require long-term follow-up to assess for the development of:
Obesity
Diabetes insipidus
Respiratory distress
Cognitive impairment
The Correct Answer is D
Choice A reason:
Obesity is not a common complication of phenylketonuria (PKU), a genetic disorder that causes increased levels of phenylalanine (an amino acid) in the body. Obesity may be related to other endocrine disorders, such as hypothyroidism or Cushing syndrome.
Choice B reason:
Diabetes insipidus is a condition that causes excessive thirst and urination due to a lack of antidiuretic hormone (ADH) or a problem with the kidneys' response to ADH. It is not caused by PKU, which affects the metabolism of phenylalanine.
Choice C reason:
Respiratory distress is not a typical symptom of PKU, although some newborns with PKU may have a musty odor in their breath, skin, or urine due to the buildup of phenylalanine.
Respiratory distress may be caused by other conditions, such as asthma, pneumonia, or congenital heart defects.
Choice D reason:
Cognitive impairment is the most serious complication of PKU if it is not diagnosed and treated early. High levels of phenylalanine can damage the brain and cause irreversible intellectual disability, neurological problems, and behavioral issues. Early intervention with a special diet that limits phenylalanine intake can prevent or reduce cognitive impairment in children with PKU.

Correct Answer is A
Explanation
Choice A reason:
Maternal/newborn blood group incompatibility is the most common cause of pathologic jaundice, which appears within the first 24 hours of life. This occurs when the mother's antibodies attack the newborn's red blood cells, causing hemolysis and increased bilirubin production. The excess bilirubin causes the yellowish discoloration of the skin and mucous membranes.
Choice B reason:
The absence of vitamin K is not related to jaundice but to hemorrhagic disease of the newborn. Vitamin K is essential for blood clotting and is given to newborns as an injection shortly after birth. Newborns are at risk of vitamin K deficiency because they have low levels of vitamin K in their bodies and breast milk, and their intestinal bacteria are not yet able to synthesize vitamin K.
Choice C reason:
Maternal cocaine abuse can cause many complications for the newborn, such as prematurity, low birth weight, neonatal abstinence syndrome, neurobehavioral problems, and congenital anomalies. However, it is not a direct cause of jaundice in the newborn.
Choice D reason:
Physiologic jaundice is a normal and benign condition that affects about 60% of term newborns. It occurs due to the immature liver's inability to metabolize bilirubin effectively. It usually appears after the first 24 hours of life and peaks around the third or fourth day. It does not require treatment unless the bilirubin level is very high or rising rapidly.
Correct Answer is A
Explanation
Choice A reason:
FAS is caused by alcohol, and NAS is caused by opioids. This is the correct answer because FAS stands for fetal alcohol syndrome, which is a condition that affects the development of a baby when the mother drinks alcohol during pregnancy. NAS stands for neonatal abstinence syndrome, which is a group of problems that can happen when a baby is exposed to opioid drugs for a length of time while in their mother's womb.
Choice B reason:
FAS and NAS are both incurable. This is incorrect because FAS and NAS are not diseases, but conditions that result from prenatal exposure to substances. FAS and NAS can cause various physical, mental, and behavioral problems in the baby, some of which may be permanent, but others may be improved with early intervention and treatment.
Choice C reason:
FAS is caused by analgesics and NAS is caused by NSAIDs. This is incorrect because analgesics are painkillers, and NSAIDs are nonsteroidal anti-inflammatory drugs. Neither of these types of drugs is known to cause FAS or NAS. However, some analgesics, such as codeine and oxycodone, are opioids and can cause NAS if used by pregnant women.
Choice D reason:
FAS and NAS are both curable. This is incorrect because FAS and NAS are not diseases, but conditions that result from prenatal exposure to substances. FAS and NAS can cause various physical, mental, and behavioral problems in the baby, some of which may be permanent, but others may be improved with early intervention and treatment. However, there is no cure for FAS or NAS.
