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, 2015. The nurse uses Naegele's Rule to calculate the correct EDD:

April 27, 2016

April 11, 2016

February 27, 2016

February 11, 2016

Answer and Explanation

The Correct Answer is D

The correct answer is: April 11, 2016

Choice A: April 27, 2016

Reason: Using Naegele’s Rule, the estimated date of delivery (EDD) is calculated by adding one year, subtracting three months, and adding seven days to the first day of the last menstrual period (LMP). For an LMP of May 4, 2015:

Add one year: May 4, 2016
Subtract three months: February 4, 2016
Add seven days: February 11, 2016

April 27, 2016, is incorrect because it does not follow the correct calculation steps.

Choice B: April 11, 2016

Reason: Following Naegele’s Rule:

Add one year: May 4, 2016
Subtract three months: February 4, 2016
Add seven days: February 11, 2016

April 11, 2016, is the correct EDD as it accurately follows the calculation steps.

Choice C: February 27, 2016

Reason: This date is incorrect because it does not follow the correct calculation steps of Naegele’s Rule. The correct EDD should be in April, not February.

Choice D: February 11, 2016

Reason: This date is also incorrect. While it follows the initial steps of Naegele’s Rule, it does not account for the full calculation, which should result in an April date, not February.

Correct Answer is B

Explanation

Choice A reason:

Monitoring weight gain is correct because appropriate weight gain helps support fetal growth and reduces risks of complications such as gestational diabetes and preeclampsia.

Choice B reason:

Using nonprescription medications without provider approval is unsafe since many over-the-counter drugs (like NSAIDs or decongestants) can harm the fetus. This shows a need for further teaching.

Choice C reason:

Telling the provider before using home remedies is appropriate, as some herbs or supplements may be unsafe in pregnancy.

Choice D reason:

Reducing stress is correct because high maternal stress can negatively affect pregnancy outcomes and fetal development.

A. "The child might develop encephalitis, a complication of rubella." B. "Exposure to rubella will suppress the newborn's immune response." C. "The newborn is at risk for developing a TORCH infection." D. "The newborn might be actively shedding the virus."

Correct Answer is D

Explanation

Choice A: While rubella can lead to complications like encephalitis, this answer does not address the reason for isolation precautions for the newborn.

Choice B: While rubella can suppress the immune response in general, it does not explain the need for isolation of the newborn specifically.

Choice C: TORCH (Toxoplasmosis, Rubella, Cytomegalovirus, and Herpes) infections are a group of infections that can be transmitted from mother to fetus during pregnancy. While rubella is part of the TORCH infections, this answer does not specifically address the reason for isolation of the newborn after delivery.

Choice D: Rubella, also known as German measles, is a contagious viral infection. Newborns born to mothers with rubella can be at risk because the virus can be transmitted to them during delivery. The newborn might be actively shedding the virus, which is why isolation precautions are necessary to prevent the spread of the infection to other vulnerable newborns or individuals.
