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:
Smoking is the most significant risk factor for clubfoot, according to several studies that have found a strong association between maternal smoking during pregnancy and the occurrence of clubfoot in the offspring. Smoking may affect the development of the muscles and tendons in the fetus, leading to abnormal positioning of the foot.
Choice B reason:
Trauma during pregnancy is not a significant risk factor for clubfoot, as there is no evidence that physical injury to the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.
Choice C reason:
Hypertension is not a significant risk factor for clubfoot, as there is no evidence that high blood pressure in the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.
Choice D reason:
Decreased circulation is not a significant risk factor for clubfoot, as there is no evidence that poor blood flow to the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.
Correct Answer is C
Explanation
Choice A reason:
Transferring the newborn to the NICU is not the best action to take next, because it does not address the immediate problem of low blood sugar. The newborn may need to be transferred to the NICU later, depending on the cause and severity of the hypoglycemia, but the first priority is to raise the blood glucose level.
Choice B reason:
Calling the lab for a STAT blood glucose level is not the best action to take next, because it will delay the treatment of hypoglycemia. The glucometer reading is a reliable indicator of low blood sugar, and waiting for a lab confirmation will waste valuable time. The nurse should act on the glucometer reading and initiate treatment as soon as possible.
Choice C reason:
Initiating breastfeeding is the best action to take next, because it will provide the newborn with a source of glucose that can raise the blood sugar level quickly. Breastfeeding also has other benefits for the newborn, such as promoting bonding, providing antibodies, and reducing the risk of infection. Breastfeeding should be initiated within the first hour of life for all newborns, unless contraindicated.
Choice D reason:
Recognizing this as a normal reading and documenting it is not the best action to take next, because it is not a normal reading for a 2 hour old newborn. The normal range of blood glucose for a newborn is 40 to 150 mg/dL. A reading of 32 mg/dL indicates hypoglycemia, which can have serious consequences for the newborn's brain development and function. Hypoglycemia should be treated promptly and documented accordingly.
