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.

Explanation
Choice A reason:
Moro is a newborn reflex that occurs when the baby is startled by a loud sound or movement. The baby will cry, throw back his or her head, and then pull his or her limbs into the body. This reflex lasts until the baby is about 2 months old.
Choice B reason:
Rooting is a newborn reflex that starts when the corner of the baby's mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.
Choice C reason:
Gag is a newborn reflex that prevents the baby from choking on foreign objects. The baby will cough, gag or spit out anything that touches the back of the throat or the roof of the mouth. This reflex is present throughout life.
Choice D reason:
Running is not a newborn reflex. It is a voluntary movement that develops later in childhood. Choice E reason:
Babinski is a newborn reflex that occurs when the sole of the foot is stroked from heel to toe. The baby will fan out and curl up the toes and twist the foot inward. This reflex lasts until the baby is about 12 months old.
Choice F reason:
Stepping is a newborn reflex that occurs when the baby is held upright with his or her feet touching a solid surface. The baby will appear to take steps or dance. This reflex lasts about 2 months.
Choice G reason:
The crawling reflex is a developmental milestone observed in infants around 6-8 months of age. It involves the baby moving on their hands and knees, often starting with a belly-crawling motion. Unlike newborn reflexes, this skill is learned and requires muscle coordination and strength.
Choice H reason:
Standing with support is a developmental milestone typically achieved by infants around 9-12 months. In this skill, the baby pulls themselves up to a standing position while holding onto furniture or a caregiver’s hands. It is a learned behavior reflecting increased muscle strength and balance, distinct from newborn reflexes.
Choice I reason:
The pincer grasp is a fine motor skill that usually develops between 8-12 months. It involves the baby using the thumb and index finger to pick up small objects. This ability is not a reflex but a learned skill that demonstrates improved hand-eye coordination and dexterity.
Correct Answer is ["A","B","E"]
Explanation
Choice A:
Tremors. This is a sign of hypoglycemia in a newborn because low blood sugar can cause shakiness or jitteriness in the muscles. •
Choice B:
Lethargy. This is a sign of hypoglycemia in a newborn because low blood sugar can cause low energy, poor feeding, or lack of interest in eating.
Choice C:
Hunger. This is not a sign of hypoglycemia in a newborn because low blood sugar can actually reduce the appetite or cause feeding difficulties.
Choice D:
Jaundice. This is not a sign of hypoglycemia in a newborn because jaundice is caused by high levels of bilirubin in the blood, not low levels of glucose.
Choice E:
Weak cry. This is a sign of hypoglycemia in a newborn because low blood sugar can affect the vocal cords and the respiratory system, causing a weak or high-pitched cry.
