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 was May 4, 2022.
Which of the following is the appropriate response by the nurse?
February 11, 2023
February 27, 2023
April 11, 2023
April 27, 2023
The Correct Answer is A
Based on your last menstrual period (LMP) of May 4, 2022, your estimated date of delivery (EDD) would be around February 11, 2023."
Rationale:
-
Calculating the Estimated Date of Delivery (EDD): The EDD can be calculated using Naegele's Rule, which is a standard method used to estimate the due date. The rule involves subtracting three months from the first day of the last menstrual period (LMP), adding seven days, and adjusting the year if necessary.
-
Application of Naegele’s Rule:
- Start with the first day of the LMP: May 4, 2022.
- Subtract three months: February 4, 2022.
- Add seven days: February 11, 2022.
- Since the year needs to be adjusted, the EDD is February 11, 2023.
Key Points:
- Naegele’s Rule is commonly used but assumes a 28-day menstrual cycle and ovulation on the 14th day. Variations in cycle length can affect the accuracy.

Correct Answer is D
Explanation
Choice A rationale
While smoking during pregnancy can have many negative effects on a baby’s health, it is not specifically linked to hearing loss.
Choice B rationale
Type 1 diabetes mellitus is not caused by maternal smoking. It is an autoimmune condition where the body’s immune system destroys the cells that release insulin.
Choice C rationale
Congenital heart defects can have many causes, including genetic factors and certain maternal health conditions. However, they are not specifically linked to maternal smoking.
Choice D rationale
Smoking during pregnancy can cause intrauterine growth restriction. This is because nicotine and other harmful chemicals in cigarettes can cross the placenta and interfere with the baby’s blood supply. This can limit the amount of oxygen and nutrients the baby receives, leading to slower growth. Placental abruptionPlacental abruption Explore
Correct Answer is D
Explanation
Choice A rationale
Tubal ligation does not decrease menstrual flow. It is a surgical procedure that blocks or seals the fallopian tubes, preventing eggs from reaching the uterus for implantation.
Choice B rationale
Tubal ligation does not reduce menstrual pain. It prevents pregnancy but does not have an effect on the menstrual cycle or associated symptoms.
Choice C rationale
The timing of the procedure in relation to the menstrual cycle is not a significant factor in tubal ligation. The procedure can be performed at any time as long as pregnancy is not present.
Choice D rationale
It is crucial to emphasize that tubal ligation is considered a permanent form of birth control. While reversal procedures exist, they are not always successful and should not be relied upon. Therefore, the decision to undergo tubal ligation should be made with the understanding that it is typically irreversible.
