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 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.
Correct Answer is ["B","C","D","F"]
Explanation
Choice A:
Temperature is not a priority finding to report to the provider. The newborn's temperature may vary slightly depending on the environment and the method of measurement. A 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 important to report to the provider because the newborn had a low Apgar score at 1 minute and required positive pressure ventilation and oxygen. The nurse should assess the newborn's respiratory rate, effort, breath sounds, and oxygen saturation. Any signs of respiratory distress, such as tachypnea, grunting, retractions, nasal flaring, or cyanosis, should be reported immediately.
Choice C:
Serum glucose is a critical finding to report to the provider because the newborn is at risk for hypoglycemia due to the abruptio placenta and the emergency cesarean birth. Hypoglycemia can cause neurological damage and seizures in newborns. A normal serum glucose level for a newborn is 40 to 60 mg/dL.
Choice D:
Hematocrit is a significant finding to report to the provider because the newborn may have polycythemia or anemia due to the abruptio placenta and the blood loss during delivery.
Polycythemia can cause hyperviscosity and thrombosis, while anemia can cause hypoxia and shock. A normal hematocrit level for a newborn is 42% to 65%.
Choice E:
White blood cell count is not a priority finding to report to the provider. The newborn's white blood cell count may be elevated due to the stress of birth or a maternal infection. A normal white blood cell count for a newborn is 9,000 to 30,000/mm3.
Choice F:
Hemoglobin is an important finding to report to the provider because the newborn may have polycythemia or anemia due to the abruptio placenta and the blood loss during delivery.
Hemoglobin is the main component of red blood cells that carries oxygen to the tissues. A normal hemoglobin level for a newborn is 14 to 24 g/dL.
Choice G:
Heart rate is a vital finding to report to the provider because the newborn had a non- reassuring fetal heart rate during labor and delivery. The nurse should monitor the newborn's heart rate and rhythm for any signs of bradycardia, tachycardia, or arrhythmias. A normal heart rate range for a newborn is 110 to 160 beats per minute.
