A patient who is pregnant expresses a desire to attempt a vaginal delivery after a cesarean birth 2 years before.
The primary care provider (PCP) initiates trial of labor after cesarean (TOLAC) and vaginal birth after cesarean (VBAC) screening.
The nurse is aware that which patient information will likely disqualify the patient for VBAC?
A low transverse uterine scar.
Patient asks multiple Questions.
First labor needed to be induced.
Cesarean due to pelvic abnormalities.
The Correct Answer is D
Choice A rationale
A low transverse uterine scar is considered the safest type of uterine incision for a VBAC because it is less likely to rupture compared to other types of scars. Therefore, a low transverse uterine scar would not disqualify the patient for VBAC.
Choice B rationale
Patient asking multiple questions does not disqualify her for VBAC. Patient education and ensuring the patient’s understanding and agreement with the procedure is an essential part of the process.
Choice C rationale
Induction of labor in the first pregnancy does not automatically disqualify a patient from attempting VBAC. The success of VBAC depends on multiple factors including the reason for the initial cesarean section.
Choice D rationale
A cesarean due to pelvic abnormalities would disqualify the patient for VBAC because the underlying pelvic condition that necessitated the initial cesarean section is likely still present and would increase the risk of complications during vaginal birth.

Correct Answer is C
Explanation
Choice A rationale
Magnesium sulfate is primarily used for neuroprotection in preterm infants and to prevent seizures in severe preeclampsia, not as a first-line tocolytic for preterm labor.
Choice B rationale
Morphine sulfate is an opioid analgesic used for pain management, not for inhibiting preterm labor contractions.
Choice C rationale
Terbutaline is a beta-agonist used as a tocolytic to relax uterine muscles and delay preterm labor. It helps decrease the intensity and frequency of contractions, making it suitable for managing preterm labor.
Choice D rationale
Betamethasone is a corticosteroid used to accelerate fetal lung maturity in preterm labor, not for direct contraction inhibition.
Correct Answer is A
Explanation
Choice A rationale
Vaginal hematomas are usually associated with severe pain due to the accumulation of blood in the tissues.
Choice B rationale
Bleeding might be visible, but hematomas often cause internal accumulation, not external bleeding.
Choice C rationale
Warmth is not typically associated with hematomas; instead, pain and swelling are more common.
Choice D rationale
Redness may occur, but pain is the most consistent symptom.
