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 B

Explanation

Choice A reason: A total placenta previa is when the placenta completely covers the internal os, blocking the baby's exit from the uterus.

Choice B reason: Placenta previa is a condition where the placenta implants in the lower uterine segment and may cover or be near the cervical internal os. When the placental edge just reaches the internal os but does not cover it, it is called a marginal previa.

Choice C reason: A complete placenta previa is when the placenta partially covers the internal os, reducing the space for the baby to pass through.

Choice D reason: "Partial placenta previa" refers to a situation where the placenta partially covers the internal cervical os — meaning some, but not all, of the opening is obstructed by placental tissue.

A. primary dysmenorrhea. B. endometriosis. C. secondary dysmenorrhea. D. PMS.

Correct Answer is B

Explanation

Choice A reason: This is incorrect because primary dysmenorrhea is menstrual pain that is not associated with any underlying condition. It usually begins with the onset of menstruation and lasts for a few days. It does not cause pain during intercourse or infertility.

Choice B reason: This is correct because endometriosis is a condition where the endometrial tissue that normally lines the uterus grows outside the uterus, such as on the ovaries, fallopian tubes, or pelvic organs. It causes chronic inflammation, scarring, and adhesions that can result in severe pain during menstruation and intercourse, as well as infertility.

Choice C reason: This is incorrect because secondary dysmenorrhea is menstrual pain that is caused by an underlying condition, such as fibroids, pelvic inflammatory disease, or adenomyosis. It usually develops later in life and lasts longer than primary dysmenorrhea. It may or may not cause pain during intercourse or infertility, depending on the condition.

Choice D reason: This is incorrect because PMS stands for premenstrual syndrome, which is a group of physical and emotional symptoms that occur before menstruation. It may include mood swings, irritability, bloating, headaches, or breast tenderness. It does not cause severe pain during menstruation or intercourse, or infertility.
