Core Nursing Explanation
Key Concept Analysis: This question tests the priority nursing action for a life-threatening postpartum complication:
Uterine inversion. This is a rare but catastrophic obstetric emergency where the uterus turns inside out, often after delivery of the placenta. The primary dangers are
profound hemorrhage from the exposed uterine lining and
neurogenic shock due to traction on pelvic ligaments and peritoneum. The patient's vital signs (BP
80/50 mmHg, HR
130 bpm) and symptoms (pallor, diaphoresis, feeling faint) indicate
Key Point! hypovolemic and neurogenic shock, making hemodynamic stabilization the absolute priority.
Answer Rationale: The correct answer is to
Establish large-bore IV access and prepare for emergency surgery. This is the foundational ABC (Airway, Breathing, Circulation) and primary survey approach.
Key Point! In a state of shock, the nurse's first role is to support circulation by establishing rapid fluid resuscitation pathways (two large-bore IVs) to replace lost volume. Simultaneously, preparing for surgery is critical because definitive treatment for a complete inversion often requires surgical intervention (e.g., manual replacement under anesthesia or a laparotomy) to correct the inversion and control bleeding. This action addresses the immediate threat to life.
Distractor Analysis:
- Option 1 (Manually replace the uterus): Watch out for confusion! While manual replacement is a definitive treatment, it is not the nurse's independent action in this scenario. Attempting manual replacement without proper analgesia, anesthesia, and potentially tocolytic drugs (to relax the uterus) can cause severe pain, worsen shock, and lead to further tissue injury or hemorrhage. This is a physician/advanced practitioner procedure.
- Option 2 (Administer oxytocin): This is contraindicated. Oxytocin causes uterine contraction. If the uterus is inverted and contracted down, administering oxytocin will tighten the cervical "ring" around the inverted fundus, trapping it and making reduction impossible. It can exacerbate the patient's condition.
- Option 3 (Trendelenburg and fundal pressure): This is dangerous and contraindicated. The Trendelenburg position (head down) does not improve shock in hemorrhagic cases and can impair respiratory function. Applying fundal pressure to an inverted uterus is absolutely wrong—it will drive the already inverted fundus further down, worsening the inversion and potentially causing uterine rupture or further hemorrhage.
Related Concepts: This emergency integrates knowledge of postpartum hemorrhage (PPH) management, shock protocols, and the specific pathophysiology of uterine inversion. Management follows a sequence: stabilize the patient (IV access, fluids, blood products), then treat the cause (often in the operating room).
