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","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.
Correct Answer is B
Explanation
Choice A reason:
Contractions every 3 to 4 min are not a definitive sign of labor, as they can also occur in false labor or Braxton Hicks contractions. These are irregular and do not cause cervical changes.
Choice B reason:
Cervical dilation is the most reliable indicator of true labor, as it shows that the uterus is contracting effectively and preparing for delivery. Cervical dilation is measured in centimeters from 0 to 10, with 10 being fully dilated.
Choice C reason:
Pain just above the navel is not a sign of labor, but rather a possible sign of an abdominal problem such as appendicitis or gallbladder disease. Labor pain usually starts in the lower back and radiates to the abdomen and thighs.
Choice D reason:
Amniotic fluid in the vaginal vault is not a conclusive sign of labor, as it can also result from a premature rupture of membranes (PROM) or a high leak of amniotic fluid. PROM occurs when the amniotic sac breaks before the onset of labor, which can increase the risk of infection and complications for the mother and the baby.
