A nurse is caring for a postpartum client who delivered 12 hours ago and is experiencing heavy vaginal bleeding with clots larger than a quarter. The client's vital signs are: BP 90/60 mmHg, HR 110 bpm, RR 22/min, and temperature 98.6°F. What is the nurse's priority intervention?

The client shows signs of postpartum hemorrhage (heavy bleeding, large clots, hypotension, tachycardia). Priority is fundal massage to stimulate uterine contraction and control bleeding, addressing the most common cause of uterine atony. Other options do not directly manage the hemorrhage.

Clinical Presentation Analysis
The client is demonstrating classic signs of early postpartum hemorrhage (PPH). The vital signs—BP 90/60 mmHg (hypotension) and HR 110 bpm (tachycardia)—indicate compensatory mechanisms for significant blood loss. The report of heavy vaginal bleeding with clots larger than a quarter 12 hours after delivery confirms a secondary or delayed PPH scenario, which is a leading cause of maternal morbidity and mortality ^[4]. The body is attempting to maintain cardiac output through increased heart rate, but the falling blood pressure signals that compensation is beginning to fail, placing the client at high risk for hypovolemic shock ^[3].

Priority Intervention Rationale
The nurse's priority intervention is to perform fundal massage and assess uterine tone. The most common cause of PPH is uterine atony, a condition where the uterus fails to contract firmly after delivery, allowing the spiral arteries at the placental site to bleed freely ^[1]. Fundal massage provides direct mechanical stimulation to the myometrium, promoting contraction and compression of these vessels. This action directly addresses the underlying pathophysiology and is a cornerstone of evidence-based nursing protocols for PPH management ^[2]. Immediate assessment of uterine tone confirms whether atony is the cause and guides the next steps in the algorithm, such as uterotonic administration ^[1].

Analysis of Other Options
- Option 1 (Administer prescribed pain medication): While pain and anxiety can increase sympathetic tone, administering medication is not the immediate priority. Pain management does not address the mechanical source of bleeding and can delay critical, life-saving interventions. Furthermore, some analgesics could exacerbate hypotension ^[3].
- Option 3 (Encourage increased fluid intake): Oral fluid intake is insufficient to compensate for acute, heavy blood loss. The client requires immediate intravenous fluid resuscitation with isotonic crystalloids to restore intravascular volume, a key component of preventing hypovolemic shock ^[3]. This is a secondary intervention after the source of bleeding is addressed.
- Option 4 (Document findings and continue monitoring): Documentation and monitoring are essential but never the priority in an acute, evolving emergency. The nurse must intervene immediately to control the hemorrhage. Delaying action to document would constitute a failure to act on critical assessment findings and could lead to rapid clinical deterioration ^[2].

Pathophysiological Connection
The loss of vascular tone at the placental implantation site leads to unchecked blood flow. Fundal massage directly stimulates the release of endogenous prostaglandins, which are crucial for sustained myometrial contraction. This mechanical intervention is the first step in a sequence that may escalate to pharmacological agents like oxytocin, as outlined in structured evidence-based protocols ^[2]. The goal is to prevent progression from compensated shock (tachycardia, mild hypotension) to decompensated shock, where organ perfusion is critically compromised ^[3].
