When administering magnesium sulfate to a client with preeclampsia, the nurse understands that this drug is given to:

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.

Choice A rationale

Placental abruption involves the detachment of the placenta from the uterine wall before delivery, causing bleeding, abdominal pain, and uterine tenderness. It does not typically cause dyspnea, hypotension, frothy sputum, or loss of consciousness.

Choice B rationale

Uterine rupture is a tear in the uterine wall, often in a scarred uterus. Symptoms include severe abdominal pain, abnormal fetal heart rate, and vaginal bleeding. It can cause shock, but not frothy sputum or sudden dyspnea.

Choice C rationale

Uterine inversion occurs when the uterus turns inside out, often during placental delivery. It leads to pain, hemorrhage, and shock. Like uterine rupture, it does not cause frothy sputum or sudden dyspnea.

Choice D rationale

Anaphylactoid syndrome (amniotic fluid embolism) occurs when amniotic fluid enters the maternal circulation, causing an anaphylactic reaction. Symptoms include sudden dyspnea, hypotension, frothy sputum, and loss of consciousness, fitting the scenario described.
