Chapter 8 : Health Problems of Newborns Questions
Question 1 of 5
When should the nurse expect breastfeeding-associated jaundice to first appear in a normal infant?
Correct Answer: C
Rationale: Breastfeeding-associated jaundice is caused by decreased milk intake related to decreased caloric and fluid intake by the infant before the mothers milk is well established. Fasting is associated with decreased hepatic clearance of bilirubin. Zero to 24 hours is too soon; jaundice within the first 24 hours is associated with hemolytic disease of the newborn. After the fifth day is too late. Jaundice associated with breastfeeding begins earlier because of decreased breast milk intake.
Question 2 of 5
Which intervention may decrease the incidence of physiologic jaundice in a healthy full-term infant?
Correct Answer: A
Rationale: Physiologic jaundice is caused by the immature hepatic function of the newborns liver coupled with the increased load from red blood cell hemolysis. The excess bilirubin from the destroyed red blood cells cannot be excreted from the body. Feeding stimulates peristalsis and produces more rapid passage of meconium. Bathing does not affect physiologic jaundice. Placing the newborns crib near a window for exposure to sunlight is not a treatment of physiologic jaundice. Colostrum is a natural cathartic that facilitates meconium excavation.
Question 3 of 5
What is an important nursing intervention for a full-term infant receiving phototherapy?
Correct Answer: A
Rationale: Dehydration is a potential risk of phototherapy. The nurse monitors hydration status to be alert for the need for more frequent feedings and supplemental fluid administration. Lotions are not used; they may contribute to a frying effect. The infant should be placed nude under the lights and should be repositioned frequently to expose all body surfaces to the lights. Breastfeeding is encouraged. Intermittent phototherapy may be as effective as continuous therapy. The advantage to the mother and father of being able to hold their infant outweighs the concerns related to clearance.
Question 4 of 5
Rh hemolytic disease is suspected in a mothers second baby, a son. Which factor is important in understanding how this could develop?
Correct Answer: B
Rationale: Hemolytic disease of the newborn results from an abnormally rapid rate of red blood cell (RB
C) destruction. The major causes of this are maternal-fetal Rh and ABO incompatibility. If an Rh-negative mother has previously been exposed to Rh-positive blood through pregnancy or blood transfusion, antibodies to this blood group antigen may develop so that she is isoimmunized. With further exposure to Rh-positive blood, the maternal antibodies agglutinate with the RBCs of the fetus that has the antigen and destroy the cells. Hemolytic disease caused by ABO incompatibilities can be present with the first pregnancy. The gender of the first child is not a concern. Blood type is the important consideration. If both parents have type O blood, ABO incompatibility should not be a possibility.
Question 5 of 5
When should the nurse expect jaundice to be present in a full-term infant with hemolytic disease?
Correct Answer: B
Rationale: In hemolytic disease of the infant, jaundice is usually evident within the first 24 hours of life. Infants with hemolytic disease are usually not jaundiced at birth, although some degree of hepatosplenomegaly, pallor, and hypovolemic shock may occur when the most severe form, hydrops fetalis, is present. Twenty-five to 72 hours after birth is too late for hemolytic disease of the infant. Jaundice at these ages is most likely caused by physiologic or early-onset breastfeeding jaundice.
