A client with last menstrual period on April 11
Question 2 of 5
A client's last menstrual period was April 11. Using Nägele's rule, her estimated date of birth (EDB) would be:
Correct Answer: B
Rationale: Nägele's rule: add 1 year, subtract 3 months, add 7 days. April 11, 2023 + 1 year = April 11, 2024; minus 3 months = January 11, 2024; plus 7 days = January 18, 2024. Other options misapply the rule.

Correct Answer: A
Rationale: Hemodilution of pregnancy occurs as plasma volume increases more than red blood cell mass, lowering hemoglobin to 10.5-14 g/dL in the second trimester, which includes 11 g/dL. Multiple gestation may raise hemoglobin, weight gain doesn't affect it, and iron-deficiency anemia typically shows lower hemoglobin with symptoms like fatigue.
