Which of these is a characteristic of a preterm infant?
Hypertonia.
Long toenails.
Lanugo.
Dry skin.
The Correct Answer is C
Choice A reason:
Hypertonia is not a characteristic of a preterm infant, but rather of a post-term infant. Hypertonia means increased muscle tone or stiffness, which is more common in infants who are overdue. Preterm infants have poor muscle tone and less subcutaneous fat.
Choice B reason:
Long toenails are also not a characteristic of a preterm infant but of a post-term infant. Long toenails indicate that the infant has grown beyond the expected gestational age. Preterm infants have short and brittle nails.
Choice C reason:
Lanugo is a characteristic of a preterm infant. Lanugo is fine, downy hair that covers the body of the fetus. It usually disappears by the 36th week of gestation, but preterm infants may still have it at birth.
Choice D reason:
Dry skin is not a characteristic of a preterm infant but of a post-term infant. Dry skin indicates that the infant has lost moisture and subcutaneous fat due to prolonged exposure to the amniotic fluid. Preterm infants have thin and transparent skin that may be covered by vernix caseosa, a white, cheesy substance that protects the skin from the amniotic fluid.

Correct Answer is ["C","D","F"]
Explanation
Choice A:
Temperature is not a finding that needs to be reported to the provider unless it is abnormally high or low. The normal temperature range for a newborn is 36.5°C to 37.5°C (97.7°F to 99.5°F).
Choice B:
Respiratory findings are not a finding that needs to be reported to the provider unless they indicate respiratory distress or infection. The normal respiratory rate for a newborn is 30 to 60 breaths per minute.
Choice C:
Serum glucose is a finding that needs to be reported to the provider, as it is higher than the normal range for a newborn. The normal serum glucose level for a newborn is usually just under 2 mmol/L (or 25 mg/dL) at birth, and it will rise to over 3 mmol/L (or 60 to 100 mg/dL) within two to three days. A serum glucose level of 130 mg/dL indicates hyperglycemia, which can have various causes and complications.
Choice D:
Hematocrit is a finding that needs to be reported to the provider, as it is lower than the normal range for a newborn. The normal hematocrit level for a newborn is 44% to 64%. A hematocrit level of 35% indicates anemia, which can have various causes and complications.
Choice E:
White blood cell count is not a finding that needs to be reported to the provider, as it is within the normal range for a newborn. The normal white blood cell count for a newborn is 9,000 to 30,000/mm³.
Choice F:
Hemoglobin is a finding that needs to be reported to the provider, as it is lower than the normal range for a newborn. The normal hemoglobin level for a newborn is 14 to 24 g/dL. A hemoglobin level of 9 g/dL indicates anemia, which can have various causes and complications.
Correct Answer is A
Explanation
Choice A reason:
Placental insufficiency is a condition in which the placenta does not deliver enough oxygen and nutrients to the developing baby, resulting in restricted growth and development. This is one of the most common causes of SGA babies.
Choice B reason:
Primipara means a woman who is pregnant for the first time or who has given birth to one child. Primipara is not a cause of SGA, although some studies have suggested that first-time mothers may have a slightly higher risk of having a low-birth-weight baby than multiparous women.
Choice C reason:
Maternal obesity is a condition in which the mother has a body mass index (BMI) of 30 or higher before or during pregnancy. Maternal obesity is not a cause of SGA, but rather a risk factor for having a large-for-gestational-age (LGA) baby, which can lead to complications such as macrosomia, shoulder dystocia, and birth trauma.
Choice D reason:
Perinatal asphyxia is a condition in which the baby does not receive enough oxygen before, during, or after birth, causing hypoxia and acidosis. Perinatal asphyxia is not a cause of SGA, but rather a possible complication of SGA, especially if the placental insufficiency is severe or prolonged. Perinatal asphyxia can damage the brain and other organs of the baby and lead to long-term neurological impairments.
