A nurse is assessing a client at their first prenatal appointment. The client reports that the first day of their last menstrual period was September 17. Which of the following accurately represents the client's estimated date of birth using Naegele's Rule?

A) Fusion of labia in female genitalia:
Fusion of the labia in a female newborn is not an expected finding. This could indicate a condition such as labial adhesion or an abnormality in the development of the genitalia. Normally, the labia in a female newborn are separated. Any signs of fusion would require further evaluation by the healthcare provider.

B) Erythema toxicum on newborn's skin:
Erythema toxicum is a common and expected finding in newborns, usually appearing within the first 2–3 days of life. It consists of small, red papules or pustules on a red base, often described as a "flea-bitten" appearance. This rash is benign and resolves on its own within a few days to weeks. It is not associated with any infection or underlying health issues.

C) Hypospadias is noted in the male newborn:
Hypospadias, a condition where the urethral opening is located on the underside of the penis rather than at the tip, is not an expected finding in all newborn males. While it occurs in a small percentage of male infants, it is a congenital anomaly that would require further assessment and possibly surgical correction. It is not considered a normal finding in a newborn.

D) Presence of syndactyly in extremities:
Syndactyly, the condition where two or more fingers or toes are fused together, is not a normal finding in newborns. While it is a congenital anomaly that can occur in some infants, it is not expected and requires further evaluation and possibly surgical intervention depending on the severity.

E) Negative Ortolani sign:
A negative Ortolani sign is an expected and normal finding in a newborn. The Ortolani maneuver is used to assess for hip dislocation, and a negative result indicates that the hip is stable and not dislocated. If the Ortolani sign were positive, it would suggest the presence of a developmental hip dysplasia, which would require further diagnostic evaluation. A negative sign is considered typical and reassuring.

A) Decrease the heart rate of the fetus:
Lying on the left side can sometimes help improve fetal oxygenation, especially if there is a concern about reduced blood flow from compression of the inferior vena cava, which can occur when the mother lies on her back. However, the primary rationale for this position is to prevent supine hypotension, not specifically to decrease fetal heart rate. In fact, side-lying can promote better oxygen exchange, which can indirectly benefit the fetal heart rate.

B) Aid the women while she pushes:
While a left-side lying position may offer comfort during labor and can help with uterine positioning, it is not specifically intended to aid in the pushing phase. Positions such as squatting or hands-and-knees are generally more helpful during the pushing phase because they can facilitate effective pushing and help the baby descend into the birth canal. The left-side position is more about circulation and preventing hypotension.

C) Prevent supine hypertension:
Supine hypotension occurs when the pregnant woman lies flat on her back, which can compress the inferior vena cava and reduce blood return to the heart. This leads to a drop in blood pressure and can compromise both maternal and fetal circulation. The left-side position is recommended because it helps to prevent this compression and allows optimal blood flow to both the mother and fetus, improving oxygenation and circulation.

D) Prevent the client from falling out of bed:
While lying on the left side may make the woman feel more stable, the primary reason for this position is to prevent supine hypotension, not to prevent her from falling out of bed. The nurse would ensure safety by using appropriate bed rails and monitoring, but the primary concern is supporting optimal circulation, not preventing falls.
