Correct Answer is ["B"]
Explanation
A. A previous low transverse uterine incision is a factor that may allow for a trial of labor after cesarean (TOLAC) or a vaginal birth after cesarean (VBAC), rather than an automatic cesarean section.
B. Placenta previa, where the placenta partially or completely covers the cervix, often requires a cesarean section to avoid complications such as bleeding during labor.
C. A previous classical uterine incision, especially if it extends into the upper part of the uterus, is a contraindication for a trial of labor or vaginal birth, usually requiring a repeat cesarean
section.
D. Prolapsed umbilical cord, where the cord precedes the presenting part, can lead to cord compression during contractions, necessitating a prompt cesarean section.
E. Breast cancer is not a direct indication for a cesarean section; it does not impact the mode of delivery in the absence of other obstetric indications.
Correct Answer is B
Explanation
A. Artificial rupture of membranes involves breaking the amniotic sac to induce or augment labor but is not a method for cervical ripening.
B. Laminaria is a common mechanical method used to ripen the cervix before labor induction.
Laminaria tents are placed in the cervix to gradually dilate and soften it.
C. A catheter filled with sterile saline may be used for cervical ripening, but it is not the most common mechanical method.
D. Membrane stripping involves separating the amniotic membrane from the cervix, not a mechanical method for cervical ripening.
