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 D
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 is incorrect because it is too early. Naegele's rule gives February 18, not January 18.
Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.
Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.

Correct Answer is A
Explanation
Choice A: Hemodilution of pregnancy is a normal physiological phenomenon that occurs when the plasma volume increases more than the red blood cell mass, resulting in a lower hemoglobin concentration. The normal hemoglobin range for pregnant women in the second trimester is 10.5 to 14 g/dL.
Choice B: A multiple gestation pregnancy may cause a higher hemoglobin level due to increased erythropoietin production by the placenta. The normal hemoglobin range for pregnant women with twins in the second trimester is 12 to 16 g/dL.
Choice C: Greater-than-expected weight gain is not related to hemoglobin level. Weight gain during pregnancy depends on various factors such as pre-pregnancy weight, nutrition, activity level, and fetal growth.
Choice D: Iron-deficiency anemia is a condition where the hemoglobin level is below the normal range due to inadequate iron intake or absorption, blood loss, or increased iron demand. The signs and symptoms of iron-deficiency anemia include fatigue, pallor, weakness, shortness of breath, and pica.
