A primigravida at 40 weeks gestation is admitted in active labor. The fetus is in a left occiput anterior (LOA) position with progressive cervical dilation and fetal descent. Vaginal exam reveals a well-applied fetal head, and the labor is progressing without complications. Based on these findings, which maternal pelvic type is most likely contributing to this optimal labor pattern?
Platypelloid pelvis
Gynecoid pelvis
Anthropoid pelvis
Android pelvis
The Correct Answer is B
A. Platypelloid pelvis: This pelvic type is characterized by a flattened inlet with a short anteroposterior diameter and a wide transverse diameter. These dimensions often lead to difficulty with fetal engagement and descent, increasing the likelihood of labor dystocia and the need for operative intervention.
B. Gynecoid pelvis: The gynecoid pelvis has a rounded inlet, wide cavity, and evenly proportioned diameters, allowing the fetal head to engage and rotate efficiently. It supports smooth labor progress, especially in a left occiput anterior position, which aligns well with this pelvic shape for spontaneous vaginal delivery.
C. Anthropoid pelvis: This pelvis is elongated anteroposteriorly and narrower transversely, predisposing the fetus to enter the pelvis in an occiput posterior position. Although vaginal birth can occur, it may be accompanied by prolonged labor or back pain due to fetal malrotation.
D. Android pelvis: The android pelvis resembles a male pelvis, with a heart-shaped inlet and narrow dimensions. These features can lead to poor fetal head engagement, deep transverse arrest, and increased need for cesarean or assisted delivery due to ineffective fetal descent.

Correct Answer is ["C","D"]
Explanation
A. Nausea with occasional vomiting: Mild nausea and occasional vomiting, commonly known as morning sickness, are typical in early pregnancy due to hormonal changes. These symptoms are expected and generally not dangerous unless they become severe or persistent, as in hyperemesis gravidarum.
B. Fatigue: Fatigue is a normal physiological response to hormonal changes, increased metabolic demands, and expanded blood volume during pregnancy. It is common in the first and third trimesters and does not usually indicate a complication.
C. Rupture of membranes: Any rupture or leakage of amniotic fluid before labor begins should be reported immediately. Premature rupture increases the risk of infection, cord prolapse, and preterm labor, requiring prompt medical evaluation.
D. Vaginal bleeding: Bleeding during pregnancy is a significant warning sign that may indicate miscarriage, placental abruption, or placenta previa. Immediate medical assessment is necessary to determine the cause and initiate appropriate management.
E. Urinary frequency: Increased urinary frequency is a normal finding during pregnancy caused by hormonal changes and uterine pressure on the bladder. It should only be reported if accompanied by pain, burning, or fever, which could indicate infection.
Correct Answer is D
Explanation
A. 3.1.0.1.1: This notation is incorrect because it indicates only one living child, whereas the client has three living children. Additionally, the preterm birth category should account for the twin delivery at 35 weeks.
B. 4.1.0.1.1: This suggests four pregnancies, but the client is currently pregnant with her third. Gravida should be 3, not 4, since she has had two prior pregnancies and is now pregnant again.
C. 4.1.1.0.3: This implies four pregnancies and one abortion, which does not align with the history provided. The client clearly stated she has had no miscarriages or abortions.
D. 3.1.1.0.3: Gravida (3) includes the current pregnancy and two prior pregnancies. Term (1) reflects the 8-year-old born at 40 weeks, Preterm (1) represents the twins born at 35 weeks, Abortions (0) indicates none, and Living (3) includes all three living children. This notation correctly represents her obstetric history.
