A nurse is caring for a laboring client who has reached the second stage of labor. Which nursing interventions are most appropriate during this stage? (Select All that Apply.)

A. Voluntary bearing down efforts: The strength, timing, and coordination of the mother's pushing efforts significantly affect fetal descent and the progress of the second stage of labor. Ineffective bearing down can delay birth, while effective efforts promote smoother fetal expulsion.

B. The shape of the woman's bony pelvis: Pelvic shape and dimensions determine how easily the fetal head can pass through the birth canal. A gynecoid pelvis is most favorable, whereas android or platypelloid types can impede progress and increase labor complications.

C. Antibiotic administration for a GBS + patient: While antibiotics are essential for preventing neonatal infection, they do not influence the physical mechanics or progression of labor. Their purpose is prophylactic rather than to affect the labor process itself.

D. Size of the fetal head: A large fetal head relative to the maternal pelvis can lead to cephalopelvic disproportion, slowing or arresting labor progress. Optimal fit between fetal head size and pelvic dimensions promotes efficient descent and delivery.

E. Presentation of the fetus: The way the fetus enters the pelvis—whether cephalic, breech, or face presentation—directly affects labor progression. Cephalic presentation, especially occiput anterior, allows for smoother navigation through the pelvis.

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.
