Choice A Reason: This is incorrect because it adds 10 months and 7 days to the last menstrual period, which is not Nägele's rule.
Choice B Reason: This is incorrect because it adds 9 months and 7 days to the last menstrual period, which is not Nägele's rule.
Choice C Reason: This is correct because it follows Nägele's rule, which is to subtract 3 months and add 7 days to the last menstrual period.

Correct Answer is B
Explanation
Choice A Reason: This is incorrect because wearing spandex-type full-length pants can constrict the blood flow and increase the swelling in the feet. The nurse should advise the woman to wear loose-fitting clothes and comfortable shoes that do not squeeze or rub her feet.
Choice B Reason: This is correct because elevating the legs when sitting can improve venous return and reduce the swelling in the feet. The nurse should encourage the woman to elevate her legs above her heart level whenever possible and avoid crossing her legs or standing for long periods.
Choice C Reason: This is incorrect because limiting the intake of fluids can cause dehydration and worsen the swelling in the feet. The nurse should recommend the woman drink plenty of water and other healthy fluids to maintain hydration and flush out excess sodium and waste products from her body.
Choice D Reason: This is incorrect because eliminating salt from the diet can cause electrolyte imbalance and affect the fluid balance in the body. The nurse should advise the woman to consume salt in moderation and avoid processed foods that are high in sodium.
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.
