A nurse is admitting a term newborn to the nursery following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow. This finding indicates the newborn is experiencing a complication related to which of the following?
Maternal/newborn blood group incompatibility
Absence of vitamin K
Maternal cocaine abuse
Physiologic jaundice
The Correct Answer is A
Choice A reason:
Maternal/newborn blood group incompatibility is the most common cause of pathologic jaundice, which appears within the first 24 hours of life. This occurs when the mother's antibodies attack the newborn's red blood cells, causing hemolysis and increased bilirubin production. The excess bilirubin causes the yellowish discoloration of the skin and mucous membranes.
Choice B reason:
The absence of vitamin K is not related to jaundice but to hemorrhagic disease of the newborn. Vitamin K is essential for blood clotting and is given to newborns as an injection shortly after birth. Newborns are at risk of vitamin K deficiency because they have low levels of vitamin K in their bodies and breast milk, and their intestinal bacteria are not yet able to synthesize vitamin K.
Choice C reason:
Maternal cocaine abuse can cause many complications for the newborn, such as prematurity, low birth weight, neonatal abstinence syndrome, neurobehavioral problems, and congenital anomalies. However, it is not a direct cause of jaundice in the newborn.
Choice D reason:
Physiologic jaundice is a normal and benign condition that affects about 60% of term newborns. It occurs due to the immature liver's inability to metabolize bilirubin effectively. It usually appears after the first 24 hours of life and peaks around the third or fourth day. It does not require treatment unless the bilirubin level is very high or rising rapidly.

Correct Answer is B
Explanation
Choice A reason:
Contractions every 3 to 4 min are not a definitive sign of labor, as they can also occur in false labor or Braxton Hicks contractions. These are irregular and do not cause cervical changes.
Choice B reason:
Cervical dilation is the most reliable indicator of true labor, as it shows that the uterus is contracting effectively and preparing for delivery. Cervical dilation is measured in centimeters from 0 to 10, with 10 being fully dilated.
Choice C reason:
Pain just above the navel is not a sign of labor, but rather a possible sign of an abdominal problem such as appendicitis or gallbladder disease. Labor pain usually starts in the lower back and radiates to the abdomen and thighs.
Choice D reason:
Amniotic fluid in the vaginal vault is not a conclusive sign of labor, as it can also result from a premature rupture of membranes (PROM) or a high leak of amniotic fluid. PROM occurs when the amniotic sac breaks before the onset of labor, which can increase the risk of infection and complications for the mother and the baby.
Correct Answer is ["B","D","F","H"]
Explanation
Choice A reason
Blood pressure is not a priority finding for a newborn with neonatal abstinence syndrome (NAS). Blood pressure is usually normal or slightly elevated in NAS, and it is not a reliable indicator of the severity of withdrawal symptoms.
Choice B reason
Gastrointestinal disturbances are a common and serious finding for a newborn with NAS. Vomiting and diarrhea can lead to dehydration, electrolyte imbalance, and poor weight gain. Projectile vomiting can also increase the risk of aspiration. This finding requires immediate follow-up and intervention.
Choice C reason
Skin color is not a priority finding for a newborn with NAS. Acrocyanosis (bluish color of the hands and feet) is a normal finding in newborns and does not indicate hypoxia or poor circulation. It usually resolves within the first few days of life.
Choice D reason
NAS score is not a priority finding for a newborn with NAS. NAS score is a tool used to assess the severity of withdrawal symptoms and the need for pharmacological treatment. It is based on a set of clinical signs and symptoms that are scored at regular intervals. However, it is not a substitute for clinical judgment and individualized care. The NAS score alone does not determine the urgency of follow-up.
Choice E reason
Temperature is not a priority finding for a newborn with NAS. Temperature may be slightly elevated or normal in NAS, and it is not a specific sign of infection or withdrawal. Temperature regulation is important for newborns, but it is not an immediate concern in this case.
Choice F reason
Oxygen saturation is a priority finding for a newborn with NAS. Tachypnea (rapid breathing) and retractions (inward movement of the chest wall) are signs of respiratory distress, which can compromise oxygen delivery to the tissues and organs. Hypoxia (low oxygen level) can cause brain damage, organ failure, and death if not corrected promptly. This finding requires immediate follow-up and intervention.
Choice G reason
Central nervous system disturbances are a priority finding for a newborn with NAS. Increased muscle tone, tremors, high-pitched cry, and seizures are signs of neurological dysfunction,which can indicate brain injury, bleeding, or infection. Seizures can also worsen hypoxia and metabolic acidosis. This finding requires immediate follow-up and intervention.
Choice H reason
Respiratory rate is not a priority finding for a newborn with NAS. Respiratory rate may be increased or normal in NAS, and it is not a specific sign of respiratory distress or infection. Respiratory rate should be monitored along with other vital signs.
