A nurse is calculating the estimated date of delivery for a client who reports that the first day of her last menstrual period was August 10. Using Nägele's Rule, which of the following is the client's estimated date of delivery?
May 20.
May 3.
May 13.
May 17.
The Correct Answer is D
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 17 as the estimated date of delivery.

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 B
Explanation
Choice A rationale:
Hct (hematocrit) of 34% is a normal finding during pregnancy. Normal ranges vary during pregnancy, but generally, a hematocrit between 33% to 45% is considered normal during the second trimester.
Choice B rationale:
BUN (blood urea nitrogen) of 25 mg/dL should be reported to the provider. BUN measures kidney function, and during pregnancy, values above 20 mg/dL may indicate possible impaired kidney function, which requires further evaluation.
Choice C rationale:
Platelets of 170,000/mm³ are within the normal range during pregnancy. The normal platelet count during pregnancy is typically between 150,000 to 400,000/mm³.
Choice D rationale:
HbA1c (glycated hemoglobin) of 6% is a good indicator of blood sugar control and is within the target range for a pregnant woman with diabetes. The target HbA1c level for pregnant women with diabetes is usually around 6% or lower.
