For which patient should the oxytocin (Pitocin) infusion be discontinued immediately?

Choice A reason:

Basal metabolic rate reduction. This is incorrect because a newborn under a radiant heat warmer will have an increased basal metabolic rate, not a reduced one. The basal metabolic rate is the amount of energy the body uses at rest, and it is influenced by temperature. A warmer environment will stimulate the newborn's metabolism and increase the energy expenditure. • Choice B reason:

Brown fat production. This is incorrect because a newborn under a radiant heat warmer will have less need for brown fat production, not more. Brown fat is a type of fat tissue that generates heat by burning calories. It is found in newborns and helps them maintain their body temperature in cold environments. A warmer environment will reduce the need for brown fat activation. • Choice C reason:

Shivering. This is incorrect because a newborn under a radiant heat warmer will not shiver, but shivering is not the main mechanism of heat production in newborns. Shivering is an involuntary contraction of muscles that generates heat by increasing metabolism. Newborns have limited ability to shiver because of their immature nervous system and low muscle mass. They rely more on brown fat and increased metabolic rate to produce heat. • Choice D reason:

Cold stress. This is correct because a newborn under a radiant heat warmer will prevent cold stress, which is a condition where the newborn's body temperature drops below normal and causes adverse effects. Cold stress can impair oxygen delivery, increase acidosis, decrease blood glucose, and increase the risk of infection and bleeding. A radiant heat warmer provides a neutral thermal environment for the newborn and prevents heat loss by radiation.

The diagram should be completed as follows:

Condition Most Likely Experiencing: B. Respiratory distress syndrome. Action to Take 1: C. Administer Surfactant as prescribed. Action to Take 2: Provide oxygen therapy as needed. Parameter to Monitor 1: B. Arterial blood gases. Parameter to Monitor 2: D. Oxygen saturation.

Conditions Explained

Choice A reason:
Hypoglycemia is a condition where the blood glucose level is too low. It can cause symptoms
such as jitteriness, lethargy, poor feeding, and seizures. However, hypoglycemia does not
explain the respiratory signs that the newborn is experiencing, such as tachypnea, grunting,
nasal flaring, and retractions. Acrocyanosis is also not a sign of hypoglycemia. Therefore,
choice A is incorrect.
Choice B reason:
Respiratory distress syndrome (RDS) is a condition where the lungs are not fully developed
and lack enough surfactant, a substance that helps the alveoli stay open and exchange
oxygen and carbon dioxide. It can cause symptoms such as tachypnea, grunting, nasal flaring,
retractions, and cyanosis. RDS is more common in premature infants, especially those born
before 37 weeks of gestation. Acrocyanosis can be a normal finding in the first 24 hours of
life, but it can also indicate poor perfusion due to respiratory compromise. Therefore, choice
B is the most likely condition that the newborn is experiencing.
Choice C reason:
Neonatal abstinence syndrome (NAS) is a condition where the newborn withdraws from

drugs that were exposed in utero. It can cause symptoms such as irritability, tremors, high-
pitched crying, poor feeding, vomiting, diarrhea, and sweating. However, NAS does not

explain the respiratory signs that the newborn is experiencing, such as tachypnea, grunting,
nasal flaring, and retractions. Acrocyanosis is also not a sign of NAS. Therefore, choice C is
incorrect.
Choice D reason:
Jaundice is a condition where the skin and sclerae turn yellow due to excess bilirubin in the
blood. It can be caused by various factors such as blood group incompatibility, hemolysis,
infection, or liver dysfunction. However, jaundice does not explain the respiratory signs that
the newborn is experiencing, such as tachypnea, grunting, nasal flaring, and retractions.
Acrocyanosis is also not a sign of jaundice.
