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 B
Explanation
Choice A reason:
Diminished deep-tendon reflexes are a sign of magnesium toxicity, not safety. Magnesium sulfate is a central nervous system depressant that can cause muscle weakness, respiratory depression, and cardiac arrest if given in excess. The nurse should monitor the client's deep-tendon reflexes and stop the infusion if they are absent or reduced.
Choice B reason:
A respiratory rate of 16/min is a normal finding and indicates that the client is not experiencing respiratory depression from magnesium sulfate. The nurse should monitor the client's respiratory rate and stop the infusion if it falls below 12/min.
Choice C reason:
A heart rate of 60/min is a normal finding and indicates that the client is not experiencing bradycardia from magnesium sulfate. The nurse should monitor the client's heart rate and stop the infusion if it falls below 50/min.
Choice D reason:
Urine output of 50 mL in 4 hr is a sign of oliguria, not safety. Magnesium sulfate can cause renal impairment and fluid retention if given in excess. The nurse should monitor the client's urine output and stop the infusion if it falls below 30 mL/hr.
