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
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 A
Explanation
Choice A Reason: This is correct because Chadwick's sign is a bluish or purplish discoloration of the cervix, vagina, and vulva caused by increased blood flow to the pelvic area during pregnancy. It is one of the earliest signs of pregnancy and can be observed as early as six to eight weeks of gestation.
Choice B Reason: This is incorrect because Goodell's sign is a softening of the cervix due to increased vascularity and edema during pregnancy. It is another early sign of pregnancy and can be detected by palpation around six to eight weeks of gestation.
Choice C Reason: This is incorrect because Hegar's sign is a softening of the lower uterine segment or isthmus during pregnancy. It is also an early sign of pregnancy and can be felt by bimanual examination around six to twelve weeks of gestation.
Choice D Reason: This is incorrect because Homan's sign is a pain in the calf or popliteal region when the foot is dorsiflexed. It is a sign of deep vein thrombosis, which is a potential complication of pregnancy, but not a normal finding.
