The nurse is calculating the estimated date of confinement (EDC) using Nagele's rule for a client whose last menstrual period started on February 13th. Which date is most accurate?

November 20

November 27

November 21

November 14

Answer and Explanation

The Correct Answer is A

Choice A reason:

Nagele's rule for calculating the estimated date of confinement (EDC) involves subtracting 3 months from the first day of the last menstrual period and adding 7 days. For February 13th, subtracting 3 months gives us November 13th, and adding 7 days gives us November 20th. This is the most accurate calculation for the estimated date of confinement.

Choice B reason:

This choice is not accurate according to Nagele's rule. Adding 7 days to November 13th would give November 20th, not November 27th.

Choice reason:

This choice is not accurate according to Nagele's rule. Adding 7 days to November 13th would give November 20th, not November 21st.

Choice D reason:

This choice is not accurate according to Nagele's rule. Subtracting 3 months from February 13th would give November 13th, not November 14th.

Correct Answer is A

Explanation

Choice A reason: A previous birth of a large infant (macrosomia) is a risk factor for gestational diabetes mellitus (GDM). A large infant may indicate that the mother had high blood glucose levels during pregnancy, which can cause the fetus to grow larger than normal. Women who have had a large infant are more likely to develop GDM in subsequent pregnancies.

Choice B reason: Underweight before pregnancy is not a risk factor for GDM. In fact, being overweight or obese before pregnancy is a risk factor for GDM, as it increases insulin resistance and makes it harder for the body to use glucose effectively.

Choice C reason: A previous diagnosis of type 2 diabetes mellitus is not a risk factor for GDM. It is a contraindication for GDM, as it means that the woman already has diabetes before pregnancy. GDM is a condition that develops during pregnancy and usually resolves after delivery.

Choice D reason: Maternal age younger than 25 years is not a risk factor for GDM. In fact, being older than 25 years is a risk factor for GDM, as it increases the risk of insulin resistance and other metabolic changes that can affect glucose tolerance.

A. Woman shorter than 62 inches or 157 cm B. Woman in early adolescence C. Woman who was 30 lbs overweight before pregnancy D. Woman pregnant with twins

Correct Answer is C

Explanation

Choice A reason: Woman shorter than 62 inches or 157 cm should not restrict her weight gain during pregnancy, as she may have a higher risk of delivering a low birth weight infant. She should follow the recommended weight gain guidelines based on her pre-pregnancy body mass index (BMI).

Choice B reason: Woman in early adolescence should not restrict her weight gain during pregnancy, as she is still growing and developing herself. She may need more calories and nutrients than an adult woman to support her own health and the fetal growth.

Choice C reason: Woman who was 30 lbs overweight before pregnancy should restrict her weight gain during pregnancy, as she may have a higher risk of developing gestational diabetes, hypertension, or preeclampsia. She should aim for a lower weight gain range than a woman with a normal BMI.

Choice D reason: Woman pregnant with twins should not restrict her weight gain during pregnancy, as she needs more energy and nutrients to support the growth of two fetuses. She should aim for a higher weight gain range than a woman with a singleton pregnancy.
