The nurse is providing preconception counseling. Which supplement should the nurse recommend to help prevent the occurrence of anencephaly?
Iron.
Vitamin D.
Folic acid.
Calcium.
The Correct Answer is C
A. Iron: While iron is important during pregnancy to prevent anemia, it does not specifically help in the prevention of anencephaly. Its main function is oxygen transport and red blood cell production.
B. Vitamin D: Vitamin D is essential for bone health by playing a role in calcium absorption, but it does not have a direct role in preventing neural tube defects such as anencephaly. It is still an important nutrient during pregnancy.
C. Folic acid: Folic acid is the key supplement recommended before and during early pregnancy to prevent neural tube defects like anencephaly. It helps in the proper development of the neural tube in the fetus.
D. Calcium: Calcium is important for fetal bone development, but it does not prevent neural tube defects like anencephaly. It is more critical later in pregnancy for the developing skeletal system.

Explanation
Rationale for Correct Choices:
- Mastitis: The client’s symptoms, including a red, warm, and firm spot on the breast, fever (101.2°F), chills, fatigue, and achiness, strongly point toward mastitis. This is an infection in breastfeeding mothers due to milk stasis or insufficient drainage, leading to infection in the breast tissue.
- Sepsis: If mastitis is left untreated or progresses, it can lead to sepsis, a systemic infection that may cause fever, tachycardia, and other systemic symptoms. The client’s fever and elevated heart rate are concerning for sepsis, which requires prompt intervention.
Rationale for Incorrect Choices:
- Endometritis: The presence of foul-smelling lochia could suggest endometritis, but the primary concern here appears to be the breast, not the uterus. The client’s symptoms, especially the localized breast pain and redness, point more to mastitis than to a uterine infection.
- Postpartum hemorrhage: Although the client has low hemoglobin (9.2 g/dL), there are no signs of significant blood loss or hemorrhage. The client is not showing symptoms like a drop in blood pressure, increased heart rate due to blood loss, or visible signs of excessive bleeding.
- Dehydration: The client reports fatigue and dizziness, but there is no indication of insufficient fluid intake or signs of dehydration (such as dry mucous membranes or concentrated urine). While dehydration can cause dizziness, the client’s primary symptoms (fever, breast pain) are more consistent with mastitis.
- Hypovolemic shock: There is no evidence of hypovolemic shock (e.g., hypotension, or signs of severe blood loss). The client’s blood pressure is stable, and there are no indications of severe volume loss, so hypovolemic shock is not a concern here.

Explanation
Rationale:
- Fundus massaged until firm and at umbilicus: Massaging the fundus until it is firm at the umbilicus indicates that uterine tone is restored, reducing the risk of postpartum hemorrhage. This is a positive sign that the uterus is contracting effectively and bleeding is controlled.
- Multiple large clots were expelled: The expulsion of multiple large clots suggests the possibility of retained blood or tissue in the uterus, which could interfere with uterine contraction and lead to continued bleeding. This increases the risk of hypovolemia.
- Blood pressure of 110/80 mm Hg, heart rate of 66 beats/minute, oxygen saturation at 98% on room air: These vital signs suggest the patient is stable, with normal blood pressure, heart rate, and oxygen saturation, indicating good circulation and oxygenation. This reflects improvement in her overall condition, decreasing the likelihood of hypovolemia.
- Fundus remains firm with slight lochia noted on pad: A firm fundus is a good sign that uterine contractions are adequate. Slight lochia is expected in the early postpartum period, and the absence of heavy bleeding suggests improved uterine tone and no active hemorrhage.
- Straight catheter produced 500 mL clear yellow urine: A 500 mL urine output indicates that the bladder is functioning well, which may also help the uterus to contract more effectively. Proper bladder function reduces the risk of uterine displacement.
- Total blood loss of 800 mL: Blood loss of 800 mL is above the typical range for a vaginal delivery (300-500 mL), which places the patient at increased risk for hypovolemia. This amount of blood loss requires close monitoring and intervention.
- 200 mL blood loss: Although 200 mL is not extreme, ongoing blood loss that exceeds the expected range for the first few hours postpartum can still place the patient at risk for hypovolemia.
