The slight overlapping of cranial bones or shaping of the fetal head during labor is called:
Valsalva maneuver.
Ferguson’s reflex.
Lightening.
Molding.
The Correct Answer is D
Choice A rationale
Valsalva maneuver involves forced expiration against a closed airway, increasing intrathoracic pressure and commonly used to expel the fetus during the second stage of labor.
Choice B rationale
Ferguson’s reflex involves the release of oxytocin due to vaginal and cervical stretching, leading to stronger contractions during the second stage of labor.
Choice C rationale
Lightening refers to the descent of the fetus into the pelvis before labor begins, reducing pressure on the diaphragm and making breathing easier.
Choice D rationale
Molding is the slight overlapping of cranial bones, allowing the fetal head to change shape and fit through the birth canal during labor.

Correct Answer is D
Explanation
Choice A rationale
Group B Streptococcus (GBS) is not typically associated with perineal sepsis; rather, it is a bacterium that colonizes the gastrointestinal and genitourinary tracts.
Choice B rationale
While GBS colonization can pose risks, chorioamnionitis is a different infection involving the membranes and amniotic fluid, often caused by a variety of microorganisms, not solely GBS.
Choice C rationale
GBS is not primarily sexually transmitted; it is a bacterium naturally present in the genital and digestive tracts, and colonization can occur without sexual contact.
Choice D rationale
Neonatal sepsis is a serious risk for babies born to mothers colonized with GBS, necessitating antibiotic prophylaxis to prevent transmission and subsequent infection in the newborn.
Correct Answer is A
Explanation
Choice A rationale
Starting Pitocin at a low dose minimizes the risk of uterine hyperstimulation, which can cause fetal distress. Gradually increasing the dose allows careful monitoring of the mother’s and fetus’s responses for optimal contraction rate.
Choice B rationale
Administering Pitocin without starting at a low dose increases the risk of uterine tachysystole, leading to potential complications like uterine rupture or placental abruption. A gradual increase ensures safer labor progression.
