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 A
Explanation
Exchange transfusion (ET) is a procedure that involves removing the infant’s blood and replacing it with compatible donor blood to reduce the level of bilirubin and/or antibody-coated red blood cells.It is a high-risk intervention that can cause serious complications such as vascular accidents, cardiovascular compromise, and electrolyte and hematologic derangement.
Therefore, it is essential to obtain informed consent from the parent before performing ET.
Choice B is wrong because checking the newborn’s blood type and crossmatch is not the first action the nurse should take.
Although it is important to ensure compatibility between the donor and recipient blood, it is not as urgent as obtaining informed consent.
Choice C is wrong because inserting two umbilical catheters for blood withdrawal and infusion is not the first action the nurse should take.
Although it is necessary to establish vascular access for ET, it is not as crucial as obtaining informed consent.
Choice D is wrong because monitoring the newborn’s vital signs and oxygen saturation is not the first action the nurse should take.
Although it is vital to assess the newborn’s condition before, during, and after ET, it is not as imperative as obtaining informed consent.
Normal ranges for bilirubin levels vary depending on the gestational age and postnatal age of the newborn.The American Academy of Pediatrics (AAP) has published nomograms for initiating phototherapy and ET based on these factors.According to the AAP, ET should be considered when the bilirubin level exceeds 25 mg/dL (428 μmol/L) in term infants or 20 mg/dL (342 μmol/L) in preterm infants with risk factors for neurotoxicity.
Correct Answer is D
Explanation
Phototherapy is a treatment that uses light to break down bilirubin in the blood and make it easier for the liver to eliminate it.
Phototherapy is effective when:
• The bilirubin levels decrease within 24 hours of treatment.
This means that the bilirubin is being cleared faster than it is being produced.
• The urine output and stool frequency increase during treatment.
This means that the bilirubin is being excreted through the kidneys and intestines.
• The skin color and muscle tone improve after treatment.
This means that the bilirubin is no longer causing jaundice or affecting the nervous system.
Statement A is wrong because it only describes one aspect of phototherapy effectiveness.
Statement B is wrong because it only describes another aspect of phototherapy effectiveness.
Statement C is wrong because it only describes the outcome of phototherapy effectiveness.
Statement D is correct because it includes all three aspects of phototherapy effectiveness.
