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

Answer and Explanation

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 A

Explanation

Choice A rationale

The nurse should include in the teaching that a client who is 23 weeks pregnant can receive an influenza vaccination during pregnancy. This is because the influenza vaccine is safe and recommended for pregnant women to protect both the mother and the baby from the flu.

Choice B rationale

The rubella vaccine is a live vaccine and is not recommended during pregnancy or while breastfeeding due to the potential risk to the baby. However, it can be given immediately after delivery if the woman is not immune.

Choice C rationale

The varicella vaccine is also a live vaccine and is not recommended during pregnancy. It should be given before pregnancy or immediately after delivery if the woman is not immune.

Choice D rationale

The Tdap (Tetanus, Diphtheria, Pertussis) vaccine is actually recommended during each pregnancy, regardless of the patient’s previous history of receiving the vaccine. The optimal timing for Tdap administration is between 27 and 36 weeks of gestation.

A. Anomalies in fetal chromosomes. B. Cephalopelvic disproportion. C. Fetal gender. D. Rh incompatibility. E. Neural tube defects.

Correct Answer is ["A","B","C","E"]

Explanation

Choice A rationale

Anomalies in fetal chromosomes can be identified through amniocentesis. This test involves the extraction of a small amount of amniotic fluid, which contains fetal tissues. The chromosomes of the fetus can be examined for abnormalities.

Choice B rationale

Cephalopelvic disproportion refers to a condition where the mother’s pelvis is too small to allow the baby to pass through the birth canal. This condition cannot be identified through amniocentesis. Amniocentesis is a diagnostic procedure that examines the amniotic fluid (not the maternal pelvis or the size of the fetus) to detect chromosomal abnormalities and certain genetic disorders.

Choice C rationale

Fetal gender can be determined through amniocentesis. The test can identify the presence of Y chromosomes, which would indicate a male fetus.

Choice D rationale

Rh incompatibility is a condition that occurs when a mother is Rh-negative and the baby is Rh-positive. This condition cannot be identified through amniocentesis. Instead, it is typically identified through blood tests of the mother and father.

Choice E rationale

Neural tube defects, such as spina bifida and anencephaly, can be identified through amniocentesis. The test can detect high levels of alpha-fetoprotein, which is often present when a fetus has a neural tube defect.
