When observing a drug-exposed newborn, what symptom suggests that the newborn may be exhibiting withdrawal symptoms?

Choice A reason:

Allowing opportunities for newborn massage is not recommended for preterm newborns, as it can increase their oxygen consumption and energy expenditure. Massage can also cause stress responses, such as increased heart rate, blood pressure, and cortisol levels.

Choice B reason:

Clustering the newborn's care activities is the best way to help the newborn conserve energy, as it minimizes the frequency of handling and stimulation. Clustering care also allows for longer periods of uninterrupted sleep, which is essential for growth and development.

Choice C reason:

Changing the newborn's position every 2 hours is not necessary for preterm newborns, as it can disrupt their sleep and cause them to lose heat. Preterm newborns have limited ability to regulate their body temperature, and frequent position changes can expose them to cold stress.

Choice D reason:

Placing elbow restraints on the newborn is not indicated for preterm newborns, unless they have a specific condition that requires them, such as a cleft lip or palate repair. Elbow restraints can restrict the newborn's movement and cause skin irritation or injury.

Choice A:

Two arteries and two veins. This is incorrect because the umbilical cord normally has only three blood vessels: one vein and two arteries. Having four blood vessels is a rare anomaly that can be associated with congenital defects. •

Choice B:

Two veins and one artery. This is incorrect because the umbilical cord normally has only one vein and two arteries. Having two veins and one artery is another rare anomaly that can also be associated with congenital defects. •

Choice C:

One artery and one vein. This is incorrect because the umbilical cord normally has two arteries and one vein. Having only one artery and one vein is a common anomaly that occurs in about 1% of singleton pregnancies and 5% of twin pregnancies. It can be associated with intrauterine growth restriction, congenital anomalies, and perinatal mortality. •

Choice D:

Two arteries and one vein. This is correct because the umbilical cord normally has two arteries and one vein. The vein carries oxygenated blood from the placenta to the fetus, while the arteries carry deoxygenated blood from the fetus to the placenta. The umbilical cord also contains Wharton's jelly, which is a gelatinous substance that protects the blood vessels from compression.
