Core Nursing Explanation
This question tests the
priority nursing action for a patient with suspected
Postpartum Hemorrhage (PPH). The patient is a primigravida with risk factors (prolonged labor, large infant), presenting with heavy bleeding 2 hours postpartum.
Key Concept Analysis
The core theme is the
Key Point! ABCs of emergency care applied to obstetric bleeding. While Airway, Breathing, and Circulation are always primary, in postpartum hemorrhage, the "C" (Circulation) is directly threatened by
Uterine Atony (the most common cause of early PPH). The priority is to identify and treat the source of bleeding immediately. The uterus is a large, vascular organ, and bleeding from the placental site can be life-threatening rapidly.
Answer Rationale
Key Point! The FIRST priority is
Assess fundal height and perform fundal massage. This action serves a dual purpose:
Assessment and Intervention.
1.
Assessment: Checking the fundus determines if it is
Boggy (soft, not well-contracted), which confirms uterine atony. A firm, contracted fundus would point to other causes of bleeding (e.g., lacerations, retained placental fragments).
2.
Intervention:
Fundal massage is a direct, non-pharmacological method to stimulate the uterine muscle to contract, which clamps down on the open blood vessels at the placental site and stops the bleeding. This can be initiated instantly by the nurse while calling for help and before administering medications.
Distractor Analysis
Watch out for confusion! All other actions are crucial but are not the
first priority.
• Option ① (Administer oxytocin): Oxytocin is the first-line
medication for uterine atony. However, the nurse must first assess the fundus to confirm atony is the cause. Massage can be started immediately while the medication is being prepared.
• Option ② (Insert large-bore IV): Establishing IV access is vital for fluid resuscitation and medication administration. However, if the uterus remains atonic, the patient will continue to bleed despite fluids. The immediate action is to stop the bleeding at its source.
• Option ④ (Prepare for transfusion): This is a critical intervention for significant blood loss, but it is a supportive measure, not a treatment for the cause. The primary goal is to stop the bleeding to prevent the need for further transfusion.
Related Concepts
This scenario highlights the "4 Ts" mnemonic for causes of PPH:
Tone (uterine atony),
Trauma (lacerations),
Tissue (retained placenta), and
Thrombin (coagulopathy). Fundal assessment addresses "Tone" first, as it is the most common. Nursing management follows the sequence: Massage → Medicate (uterotonics like oxytocin, methylergonovine, carboprost) → Manually explore/repair (if needed).
Concept Summary
•
Postpartum Hemorrhage (PPH): Blood loss >500 mL after vaginal birth or >1000 mL after cesarean.
•
Uterine Atony: Failure of the uterus to contract adequately after delivery; the #1 cause of early PPH.
•
Fundal Massage: First-line, immediate nursing intervention for a boggy uterus.
•
Nursing Priority: Always assess (find the cause) before intervening when the patient is stable enough for a quick assessment. In hemorrhage, assess the fundus first.
Side-by-Side Comparison!
| Intervention | Purpose | Priority Sequence |
|---|
| Fundal Assessment & Massage | Diagnose & treat uterine atony immediately. | FIRST - Do this while calling for help. |
| Administer Uterotonics (Oxytocin) | Pharmacologically induce uterine contraction. | Second - Initiate after/during massage. |
| Establish Large-Bore IV Access | Provide route for fluids, blood, medications. | Concurrent/Immediately after - Often done by a second nurse. |
| Prepare for Blood Transfusion | Replace lost volume and clotting factors. | Later - Based on ongoing assessment and lab values (Hgb/Hct). |
Anatomy, Physiology & Pharmacology Points
•
Physiology: After placental separation, the uterus contracts to constrict the spiral arteries that supplied the placenta. This is the primary mechanism for hemostasis.
•
Pharmacology - Oxytocin: Acts on uterine myometrium to stimulate rhythmic contractions. Given IV infusion or IM. Side effect: water intoxication (due to ADH-like effect).
•
Pharmacology - Methylergonovine: Causes sustained tetanic uterine contraction. Contraindicated in hypertension. Given IM.
Memory Tips
•
M.A.M.A. for PPH priority:
Massage →
Assess (vitals, fundus) →
Medicate →
Access (IV).
• Think:
"Stop the bleeding FIRST, then support the system." The fundus is the "tap." Turn it off (massage/contract) before you try to refill the bucket (IV fluids/transfusion).
High-Frequency NCLEX Topics
Postpartum hemorrhage is a classic
High Yield OB emergency. The NCLEX loves to test:
1. Identifying risk factors (prolonged labor, overdistended uterus, multiparity).
2.
Prioritizing actions (massage/assessment first).
3. Knowing medication indications and contraindications (e.g., don't give methylergonovine to a hypertensive patient).
Watch Out for Question Variations!
• If the question adds: "The fundus is firm and midline, but bleeding is heavy," the priority shifts to inspecting for
Trauma (lacerations of cervix/vagina).
• If the patient is
hypotensive and tachycardic (in shock), the priority actions might include calling a code, initiating
Two large-bore IVs, and administering oxygen
concurrently with fundal massage, as the patient's systemic circulation is now the immediate threat.
