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
Jitteriness and poor feeding are common signs of hypoglycemia in a newborn.
Hypoglycemia is when the level of sugar (glucose) in the blood is too low.
Glucose is the main source of fuel for the brain and the body.In a newborn baby, low blood sugar can cause problems such as shakiness, blue tint to the skin, and breathing and feeding problems.
Choice A is wrong because hypertension and bradycardia are not typical symptoms of hypoglycemia in a newborn.
They may indicate other conditions such as heart problems or infection.
Choice B is wrong because diarrhea and vomiting are not specific symptoms of hypoglycemia in a newborn.
They may be caused by many other factors such as infection, food intolerance, or gastroesophageal reflux.
Choice D is wrong because hyperactivity and irritability are not usual symptoms of hypoglycemia in a newborn.
They may be signs of other conditions such as pain, hunger, or overstimulation.
Normal ranges for blood glucose levels in newborns vary depending on the age, gestational age, and feeding status of the baby.Most doctors consider blood glucose that is below 47 milligrams per deciliter (mg/dl) to be the definition of hypoglycemia in newborns.
However, some babies may need higher levels to prevent brain injury.
A doctor will monitor the blood glucose levels of a newborn at risk for hypoglycemia and treat accordingly.
Correct Answer is B
Explanation
Encouraging frequent breastfeeding.
This is because breastfeeding provides glucose to the newborn baby, which can help prevent or treat hypoglycemia (low blood sugar).Hypoglycemia can cause problems such as shakiness, blue tint to the skin, and breathing and feeding problems.
Choice A is wrong because administering IV insulin would lower the blood sugar level even more, which could be dangerous for the baby.
Choice C is wrong because monitoring blood pressure is not directly related to hypoglycemia.
Blood pressure may be affected by other factors such as stress, infection, or dehydration.
Choice D is wrong because administering a hypertonic saline solution would increase the sodium level in the blood, which could cause dehydration and electrolyte imbalance.
A hypertonic saline solution is not a source of glucose for the baby.
Normal ranges for blood glucose levels in newborns are between 47 to 85 mg/dL.Hypoglycemia is defined as blood glucose below 47 mg/dL.
