A nurse in a prenatal clinic is caring for a client who asks what her estimated date of delivery will be if her last menstrual period began on November 15th.Which of the following is the appropriate response by the nurse?
July 12.
August 12.
August 22.
July 22.
The Correct Answer is D
Choice A rationale
Calculating the estimated date of delivery (EDD) involves adding 280 days (40 weeks) to the first day of the last menstrual period (LMP). Starting from November 15th, adding 280 days results in an EDD around August 22nd, not July 12th.
Choice B rationale
Using the same calculation method, adding 280 days to November 15th results in an EDD around August 22nd, not August 12th.
Choice C rationale
This choice is close but not accurate. Adding 280 days to November 15th results in an EDD around August 22nd.
Choice D rationale
This is the correct calculation. Adding 280 days to November 15th results in an EDD around August 22nd.

Correct Answer is A
Explanation
Choice A rationale
The uterus can indeed increase in size by 20 times its non-pregnant size. This significant expansion is necessary to accommodate the growing fetus and the increased blood supply required during pregnancy.
Choice B rationale
While the weight of the uterus does increase significantly during pregnancy, from about 100 grams to approximately 1,000 grams, this statement does not directly address the client’s concern about the uterus’s ability to stretch.
Choice C rationale
About 25% of the increased capacity of the uterus is related to uteroplacental content, but this does not fully explain the uterus’s ability to stretch to accommodate a full-term baby.
Choice D rationale
The increase in uterus size during pregnancy is not solely related to amniotic fluid volume. The uterus itself grows and stretches significantly to accommodate the developing fetus.
Correct Answer is D
Explanation
Choice A rationale
Having a child with blue eyes is not an indication for genetic testing. Eye color is a polygenic trait and does not typically warrant genetic testing.
Choice B rationale
Reactive airway disease in preterm children is not a direct indication for genetic testing. This condition is more related to the complications of prematurity rather than genetic factors.
Choice C rationale
Neonatal jaundice is common and usually resolves without long-term issues. It is not typically an indication for genetic testing unless there is a suspicion of an underlying genetic disorder.
Choice D rationale
Tay-Sachs Disease is a genetic disorder, and having a child with this condition is a strong indication for genetic testing. This would help determine the risk of recurrence in future pregnancies and provide valuable information for family planning. .
