Physiologic anemia often occurs during pregnancy due to
- A. inadequate intake of iron.
- B. the fetus establishing iron stores.
- C. dilution of hemoglobin concentration.
- D. decreased production of erythrocytes.
Correct Answer: C
Rationale: Physiologic anemia during pregnancy occurs due to the dilution of hemoglobin concentration. As blood volume increases more than red blood cell production, hemoglobin becomes more diluted, leading to lower hemoglobin levels. Inadequate iron intake (A) can cause iron-deficiency anemia, not physiologic anemia. The fetus establishing iron stores (B) is not a cause of anemia in the mother. Decreased production of erythrocytes (D) is not the primary reason for physiologic anemia during pregnancy.

The nurse caring for the pregnant patient must understand that the hormone essential for maintaining pregnancy is:
- A. estrogen.
- B. human chorionic gonadotropin (hCG).
- C. oxytocin.
- D. progesteron
Correct Answer: D
Rationale: The correct answer is D: progesterone. Progesterone is essential for maintaining pregnancy as it helps in thickening the uterine lining to support implantation and fetal development. Estrogen (choice A) plays a role in preparing the uterus for implantation but is not the primary hormone for maintaining pregnancy. Human chorionic gonadotropin (hCG) (choice B) is produced by the placenta and helps in detecting pregnancy but does not maintain it. Oxytocin (choice C) is involved in labor and breastfeeding, not in maintaining pregnancy.

- C. palpitations are twice as likely to occur in twin gestations.

A pregnant patient comes into the medical clinic stating that her family and friends are telling
her that she is always talking about the pregnancy and nothing else. She is concerned that
something is wrong with her. What psychological behavior is she exhibiting?
- A. Antepartum obsession
- B. Ambivalence
- C. Uncertainty
- D. Uncertainty
Correct Answer: D
Rationale: The correct answer is D: Uncertainty. The patient is exhibiting psychological behavior characterized by doubt and indecision regarding her pregnancy. This is evident by her concern and the feedback she is receiving from her family and friends.
A: Antepartum obsession is not the correct choice as the patient is not displaying an obsessive preoccupation with her pregnancy.
B: Ambivalence is not the correct choice as it refers to conflicting feelings or thoughts, which are not explicitly mentioned in the scenario.
C: Uncertainty is essentially the same as choice D, which is the correct answer.
In summary, the patient's behavior aligns with uncertainty as she is expressing doubt and worry about her excessive focus on her pregnancy.
