A client's last menstrual period was April 11. Using Naegele's rule, her estimated date of birth (EDB) would be:

February 24

January 18

January 25

February 18

Answer and Explanation

The Correct Answer is B

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This choice is correct because applying Naegele’s rule to the provided menstrual date (add seven days to the LMP, then subtract three months) produces the expected estimated delivery timeframe. The method yields the appropriate calendar month and day consistent with a full-term pregnancy calculation.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This option is incorrect because it places the estimated delivery about one month later than the correct result. It appears to come from adding months without the proper day adjustment or from misapplying Naegele’s rule, resulting in a date that is too far into February.

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because Ortolani's sign is a test for hip dysplasia in infants, not a sign of pregnancy. It involves moving the infant's legs to check for a clicking sound in the hip joint.

Choice B Reason: This is incorrect because Chadwick's sign is a bluish or purplish discoloration of the cervix, vagina, and vulva during pregnancy, not a softening of the lower uterine segment. It is caused by increased blood flow to the pelvic area.

Choice C Reason: This is incorrect because Goodell's sign is a softening of the cervix during pregnancy, not a softening of the lower uterine segment. It is caused by increased vascularity and edema of the cervical tissue.

Choice D Reason: This is correct because Hegar's sign is a softening of the lower uterine segment or isthmus during pregnancy. It can be felt by bimanual examination around six to twelve weeks of gestation.

A. 3-2-1-0-3 B. 4-1-1-1-3 C. 4-2-1-3-1 D. 3-1-2-2-3

Correct Answer is B

Explanation

Choice A Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one preterm birth (the twins), not two.

Choice B Reason: This option is correct because it accurately reflects the client's obstetric history. GTPAL stands for Gravida, Term, Preterm, Abortions, and Living children. Gravida is the number of pregnancies a woman has had, regardless of outcome. Term is the number of pregnancies that ended at or beyond 37 weeks gestation. Preterm is the number of pregnancies that ended between 20 and 36 weeks gestation. Abortions are the number of pregnancies that ended before 20 weeks gestation, either spontaneously or induced. Living children are the number of children who are alive at present.
The client has had four pregnancies (gravida), one term birth (the son), one preterm birth (the twins), one abortion (the miscarriage), and three living children (the twins and the son).

Choice C Reason: This option is incorrect because it overestimates the number of preterm births (preterm) and underestimates the number of living children (living). The client has had one preterm birth (the twins), not two. The client has three living children (the twins and the son), not one.

Choice D Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of abortions (abortions) and preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one abortion (the miscarriage), not two. The client has had one preterm birth (the twins), not two.
