A client with blood type AB negative delivers a newborn with blood type A positive. The cord blood reveals a positive indirect Coombs' test. What is the implication of this finding?

The newborn is infected with an infectious blood-borne disease.

The mother no longer needs Rho (D) immune globulin injections.

The mother's Rh antibodies are present in the neonatal serum.

The newborn needs phototherapy for physiologic jaundice.

Answer and Explanation

The Correct Answer is C

A positive indirect Coombs' test indicates that the mother has developed Rh antibodies against the baby's Rh-positive blood. This finding can result in hemolytic disease of the newborn, which is a condition in which the mother's Rh antibodies atack the baby's red blood cells, causing destruction and potential anemia.

The baby may require phototherapy for physiologic jaundice, but the Coombs' test result indicates a diﬀerent issue.

The presence of an infectious blood-borne disease cannot be determined from this test.

The mother may still need Rho (D) immune globulin injections after delivery of an Rh-positive baby.

Correct Answer is C

Explanation

Phyto menadione injectable, also known as vitamin K1, is commonly given to newborns to prevent hemorrhagic disease of the newborn (HDN), a bleeding disorder that can occur due to vitamin K deficiency in the first few days of life. Vitamin K is important for the production of clotting factors in the liver, and newborns are at risk of vitamin K deficiency because it does not cross the placenta well and their intestinal ﬂora is not yet established. The other options do not accurately describe the purpose of administering Phyto menadione injectable to newborns.

A. Maternal serum alpha-feto protein (MSAFP). B. Repeat indirect Coombs' test. C. Glucose tolerance test (GTT). D. Group B Streptococcus culture.

Correct Answer is A

Explanation

The screening test that should be scheduled for a client who is gravida 4 para 3 at 16-weeks gestation is **Maternal serum alpha-feto protein (MSAFP)**. Second trimester prenatal screening may include several blood tests, called multiple markers. These markers provide information about a woman's risk of having a baby with certain genetic conditions or birth defects. Screening is usually done by taking a sample of the mother's blood between the 15th and 20th weeks of pregnancy (16th to 18th is ideal)².
