A nurse is developing an educational program about hemolytic disease in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?
The mother and the father are both Rh positive.
The mother is Rh positive and the father is Rh negative.
The mother is Rh negative and the father is Rh positive.
The mother and the father are both Rh negative.
The Correct Answer is C
Choice A rationale:
If both the mother and the father are Rh positive, there is no risk of hemolytic disease in the newborn due to Rh incompatibility. Hemolytic disease of the newborn occurs when the mother is Rh negative and the father is Rh positive.
Choice B rationale:
When the mother is Rh positive and the father is Rh negative, there is no risk of hemolytic disease in the newborn. Hemolytic disease results from Rh incompatibility, which occurs when the mother is Rh negative, and the father is Rh positive.
Choice C rationale:
This is the correct answer. Hemolytic disease of the newborn occurs when the mother is Rh negative, and the father is Rh positive. In such cases, the baby may inherit the Rh factor from the father, leading to Rh incompatibility between the mother and the baby's blood, potentially causing hemolytic disease.
Choice D rationale:
If both the mother and the father are Rh negative, there is no risk of hemolytic disease in the newborn due to Rh incompatibility. Hemolytic disease of the newborn occurs when the mother is Rh negative and the father is Rh positive.

Correct Answer is C
Explanation
Choice A rationale:
The nurse should not tell the client that she cannot have an amniocentesis until she is at least 35 years of age. Age is not the primary factor for determining the eligibility for an amniocentesis. Amniocentesis is typically performed when there is a medical indication, such as advanced maternal age, abnormal prenatal screening, or a family history of genetic disorders.
Choice B rationale:
The nurse should not schedule the amniocentesis for later today without further clarification from the provider. Scheduling medical procedures without the provider's approval is not within the nurse's scope of practice and could lead to potential risks.
Choice C rationale:
This is the correct answer. The nurse should explain to the client that amniocentesis is a procedure used to determine if the baby has genetic or congenital disorders. It involves the extraction of a small amount of amniotic fluid to analyze the fetal cells for genetic abnormalities.
Choice D rationale:
The nurse should not tell the client that her provider will schedule a chorionic villus sampling (CVS) to determine the sex of the baby. CVS is another prenatal diagnostic test, but its primary purpose is to detect genetic disorders early in pregnancy, not to determine the baby's sex.
Correct Answer is D
Explanation
Choice A rationale:
To calculate the estimated date of delivery using Nägele's Rule, subtract three months from the first day of the last menstrual period (August 10), and then add seven days. However, choice A (May 20) is incorrect because it adds eight days instead of seven.
Choice B rationale:
It does not add seven days to the calculation.
Choice C rationale:
It adds three days instead of seven to the calculation
Choice D rationale:
It follows the correct application of Nägele's Rule. Subtracting three months from August 10 gives us May 10, and then adding seven days gives us May 17as the estimated date of delivery.
