A postpartum client delivered a 4,200-gram infant via cesarean section 3 hours ago and is experiencing heavy vaginal bleeding. The nurse assesses a boggy uterus that does not respond to fundal massage. Vital signs are: BP 90/60 mmHg, HR 120 bpm, RR 24/min. What is the nurse's priority action?

해설
Administering oxytocin is the priority action for uterine atony unresponsive to massage to induce uterine contraction and control bleeding. Other actions like IV access or notifying the provider are important but secondary.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for postpartum hemorrhage (PPH) due to uterine atony (a soft, boggy uterus). Uterine atony is the most common cause of PPH. The pathophysiological mechanism is the failure of the uterine muscle fibers to contract effectively after placental separation, which prevents the compression of the spiral arteries at the placental site, leading to heavy bleeding. The scenario presents classic risk factors: a large infant (>4,000 grams) and a cesarean delivery. The key finding is a boggy uterus unresponsive to initial fundal massage, indicating severe atony.

Answer Rationale: Key Point! The priority action is to administer the prescribed uterotonic medication, oxytocin (Pitocin). This is the first-line pharmacological treatment for uterine atony. Oxytocin stimulates powerful uterine contractions, which clamp down on the bleeding vessels at the placental site. In a protocol-driven emergency like PPH, the nurse is expected to administer standing-order medications (like oxytocin) immediately without waiting for a new order, as time is critical to prevent hypovolemic shock. The patient is already showing signs of shock (tachycardia HR 120, hypotension BP 90/60), making rapid intervention essential.

Distractor Analysis: Watch out for confusion! While inserting a second IV (②) is a crucial action for fluid resuscitation in a bleeding patient, it is secondary to the specific treatment for the cause of the bleeding. You must treat the cause (uterine atony) while supporting circulation. Notifying the provider (③) is important, but in an emergency protocol for PPH, administering the first-line drug is an independent nursing action that should occur simultaneously with or immediately before the call. Elevating legs and applying oxygen (④) are supportive measures for shock management but do not address the root cause of the hemorrhage.

Related Concepts: This integrates knowledge of postpartum assessment, the "4 T's" mnemonic for PPH causes (Tone, Trauma, Tissue, Thrombin), emergency response protocols, and shock management. The nursing process here requires rapid assessment (boggy uterus, vital signs), diagnosis (risk for deficient fluid volume), planning (immediate intervention to control bleeding), and implementation (administering oxytocin).
Concept Summary
ConceptKey Points
Uterine AtonyMost common cause of PPH. Uterus is boggy (soft) due to lack of contraction. Risk factors: overdistended uterus (large baby, multiples), prolonged labor, rapid labor, infection.
Oxytocin (Pitocin)First-line uterotonic. Stimulates uterine contractions. Often given as IV infusion or IM injection per protocol for PPH.
Postpartum Hemorrhage (PPH)Blood loss >1000 mL after birth or any blood loss causing signs of hypovolemia. A leading cause of maternal mortality.
Nursing Priority in PPH1. Identify cause (assess uterus). 2. Treat cause (e.g., massage, medications). 3. Support circulation (IV fluids, oxygen). 4. Notify team.

Side-by-Side Comparison!
InterventionPriority/RationaleWhen It's the Answer
Administer OxytocinDirectly treats the primary cause (uterine atony). Stops bleeding at its source.When the cause is identified as uterine atony and medication is available/ordered.
Establish IV AccessSupports circulation for fluid/medication administration. Critical but supportive.When no IV access exists, or as a simultaneous action after administering the first-line drug.
Notify ProviderEssential for escalating care and obtaining further orders.When the situation is unstable and beyond standing orders, or as a concurrent action.

Anatomy, Physiology & Pharmacology Points Physiology: After delivery, the placenta separates, leaving open spiral arteries in the uterine wall. Uterine contractions are the primary mechanism for hemostasis, physically compressing these vessels. Atony means this mechanism fails.
Pharmacology: Oxytocin binds to receptors on uterine smooth muscle, increasing intracellular calcium, which triggers strong, rhythmic contractions. Other uterotonics include methylergonovine (causes vasoconstriction), carboprost (causes strong contractions), and misoprostol (promotes contractions).
Memory Tips Mnemonic for PPH Causes: The 4 T's
Tone (Uterine atony - #1 cause)
Trauma (Laceration, hematoma)
Tissue (Retained placenta fragments)
Thrombin (Coagulopathy)
Priority Action Flow: "Massage, Medicate, Maintain (circulation), Mobilize (team)." For atony unresponsive to massage, MEDICATE is the immediate next step.
High-Frequency NCLEX Topics Postpartum hemorrhage is a High Yield topic. NCLEX loves to test: 1) Identifying risk factors for PPH, 2) Assessing for a boggy fundus, 3) Knowing the first-line interventions (fundal massage, oxytocin), and 4) Prioritizing actions in an emergency scenario. Remember: Treat the cause first when you know it.
Watch Out for Question Variations! * Variation 1: "The nurse massages a boggy fundus, but bleeding continues. What is the next action?" → Answer: Administer prescribed uterotonic (oxytocin). * Variation 2: "The client has heavy bleeding and a firm, contracted uterus." → This points away from atony. The priority might be to inspect for lacerations (Trauma) or notify the provider for possible retained placenta (Tissue). * Variation 3: Asking for the priority assessment → This would be "Assess uterine tone (check if boggy)."

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on the postpartum unit. Your patient, 3 hours post-cesarean, calls you to her room stating she feels "really wet." You find her peripad saturated with bright red blood, and a pool of blood on the bed. You immediately perform a fundal check—it is soft, boggy, and displaced to the right. You begin firm, circular fundal massage, but the uterus does not firm up and bleeding continues.

Nursing Intervention Strategy: 1. Call for Help: Activate the emergency call light or shout for another nurse. PPH is a team effort. 2. Administer Uterotonic: While massaging, instruct your colleague to draw up and administer the oxytocin (Pitocin) 10-40 units in 1L IV fluid per protocol, or give 10 units IM if no IV is running. This is your priority action to treat the cause. 3. Continue Bimanual Massage: If fundal massage is ineffective, you may need to perform bimanual compression (one hand in the vagina pushing the uterus up, the other on the abdomen pushing down) to mechanically compress the uterus while medications take effect. 4. Support Circulation: A second nurse should establish a second large-bore (16-18 gauge) IV line, run isotonic crystalloids (Normal Saline or Lactated Ringer's) wide open, apply oxygen via non-rebreather mask at 10-15 L/min, and monitor vital signs continuously. 5. Notify the Provider & Prepare for Escalation: The charge nurse or another team member notifies the obstetrician/CNM and anesthesia. Prepare for additional medications (methylergonovine, carboprost), possible transfer to OR, or blood transfusion.
Nursing Procedure & Medication Flow Oxytocin Administration in PPH: * Route: IV infusion is most common for active management. IM injection is also effective if IV access is difficult initially. * Dose: Typical PPH protocol: 10-40 units in 500-1000 mL of isotonic IV fluid. Infuse at a rapid rate initially (e.g., 200-500 mL/hr) to achieve uterine contraction, then titrate down. * Monitoring: Continuously assess uterine firmness and vaginal bleeding. Monitor for side effects: Watch out for confusion! Water intoxication (from antidiuretic effect) with prolonged high-dose infusion, and hypotension (transient). * Contraindications/Cautions: Use with caution in patients with cardiac disease. Not used for elective induction in this context.
A Word from Your Senior Nurse "In postpartum, we say 'a firm fundus is a happy fundus.' When you feel that boggy uterus, your adrenaline will spike—that's normal. Your training kicks in. Remember your ABCs with a maternity twist: Assess the uterus (Airway is usually patent), Bleeding control (Massage & Medicate!), Circulation support. Don't panic and jump straight to calling the doctor before doing what you're empowered to do. You have the tools (your hands and that oxytocin vial) to save a life. Knowing and acting on that protocol is the difference between a controlled situation and a catastrophe. Study these emergency algorithms until they're second nature."
