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
Explanation
Choice A reason:
Intermittent abdominal pain following passage of bloody mucus is not a sign of placenta previa, but rather of bloody show, which is a normal occurrence in late pregnancy as the cervix begins to dilate and efface.
Choice B reason:
Abdominal pain with minimal red vaginal bleeding is not a sign of placenta previa, but rather of abruptio placentae, which is a serious complication where the placenta detaches from the uterine wall before delivery.
Choice C reason:
A large amount of bright red vaginal bleeding without pain is a sign of placenta previa, which is a condition where the placenta covers part or all of the cervical opening. This can cause bleeding when the cervix dilates or contracts, especially in the third trimester. This is a medical emergency that requires immediate attention.
Choice D reason:
Severe abdominal pain with increasing fundal height is not a sign of placenta previa, but rather of uterine rupture, which is a rare but life-threatening complication where the uterus tears open along the scar line from a previous cesarean delivery or other uterine surgery. This can cause severe bleeding, fetal distress, and shock.
