A baby’s blood type is B negative.
The baby is at risk for hemolytic jaundice if the mother has which of the following blood types?
O positive
AB negative
B positive
A negative.
The Correct Answer is C
The baby is at risk for hemolytic jaundice if the mother has a different blood type that is incompatible with the baby’s blood type. This can cause the mother’s immune system to produce antibodies that attack the baby’s red blood cells, leading to hemolysis or excessive destruction of red blood cells. Hemolysis can cause bilirubin, a yellowish pigment, to accumulate in the baby’s blood, tissues, and fluids, causing jaundice. It can also cause anemia, a condition where the blood does not have enough healthy red blood cells.
Choice A is wrong because O positive is compatible with B negative.
O positive is the universal donor, meaning it can donate blood to any other blood type without causing a reaction.
Choice B is wrong because AB negative is compatible with B negative.
AB negative is the universal recipient, meaning it can receive blood from any other blood type without causing a reaction.
Choice D is wrong because A negative is incompatible with B negative.
A negative and B negative are different blood types that can cause a reaction if mixed together.

Correct Answer is C
Explanation
Discontinue the oxytocin (Pitocin) infusion.This is because the fetal heart rate (FHR) drops sharply from the baseline for 30 seconds during the peak of a contraction and then returns to the baseline before the end of the contraction indicate alate deceleration, which is a sign offetal hypoxia.Oxytocin is a drug that stimulates uterine contractions and can causeuterine hyperstimulation, which reduces blood flow to the placenta and the fetus.By stopping the oxytocin infusion, the nurse can reduce the frequency and intensity of contractions and improve fetal oxygenation.
Choice A is wrong because administering oxygen via facemask may not be enough to reverse fetal hypoxia if oxytocin is still being infused.Choice B is wrong because placing the client on her left side may improve maternal blood flow to the placenta, but it will not reduce the effects of oxytocin on uterine activity.
Choice D is wrong because notifying the healthcare provider is not the most urgent action at this time.The nurse should first discontinue the oxytocin infusion and then notify the healthcare provider.
Normal ranges for FHR are 110 to 160 beats per minute, with a baseline variability of 6 to 25 beats per minute.
Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting
Correct Answer is B
Explanation
Loose, peeling skin without lanugo or vernix is a symptom of post-term infants who have intrauterine growth restriction (IUGR).Post-term infants are born after 42 weeks of gestation and may have reduced placental function, resulting in less nutrition and oxygen for the fetus.This can cause them to have low birth weight, decreased subcutaneous fat and muscle mass, and dry skin.
Choice A is wrong because a large head in proportion to body size is not a sign of IUGR.It may indicate a congenital anomaly or a chromosomal disorder.
Choice C is wrong because increased subcutaneous fat and muscle mass are not signs of IUGR.They are signs of normal fetal growth and development.
Choice D is wrong because hypertonia and hyperreflexia are not signs of IUGR.They may indicate a neurological problem or a perinatal asphyxia (lack of oxygen during birth).
