해설
In DIC, bleeding manifestations like petechiae and ecchymoses are the priority due to platelet consumption and clotting factor depletion. Other options are related to preeclampsia but not the most urgent in DIC.
Understanding the Priority in HELLP Syndrome with DIC
When a client with HELLP syndrome develops disseminated intravascular coagulation (DIC), the nurse must rapidly identify the complication that poses the most immediate threat to life. HELLP syndrome is characterized by hemolysis, elevated liver enzymes, and low platelet count (thrombocytopenia) [1]. The progression to DIC represents a catastrophic failure of the coagulation system, where widespread clotting and simultaneous bleeding occur. The priority assessment finding is the one that signals active, systemic hemorrhage, which can lead to hypovolemic shock and death far more rapidly than organ-specific complications like renal failure or severe hypertension.
Analysis of the Priority Finding: Petechiae and Ecchymoses
The correct answer is the presence of petechiae and ecchymoses on the extremities. In the context of known DIC, these skin manifestations are not merely signs of a low platelet count; they are the visible, external markers of a profound systemic bleeding diathesis. The underlying pathophysiology begins with the severe thrombocytopenia inherent to HELLP syndrome, which is a core diagnostic criterion [1]. As DIC develops, platelets and clotting factors are pathologically consumed in the formation of microthrombi throughout the vasculature. This consumption leaves the patient with a critical deficit of the components needed to form a stable clot. The petechiae and ecchymoses are the clinical evidence of this failure, indicating that the patient is actively bleeding from capillary beds and into soft tissues. This finding is the priority because it directly visualizes the life-threatening hemorrhagic phase of DIC, which can quickly escalate to internal hemorrhage in the brain, gastrointestinal tract, or lungs.
Why Other Findings Are Not the Immediate Priority
While the other options represent serious complications of HELLP syndrome, they do not carry the same immediate, life-threatening risk of exsanguination as active bleeding in DIC.
- Decreased urine output of 20 mL/hour: This is a classic sign of acute kidney injury, a common and serious complication of preeclampsia and HELLP syndrome due to glomerular endotheliosis and reduced renal perfusion. However, the progression from oliguria to a life-threatening state of fluid overload, electrolyte imbalance, or uremia typically occurs over hours to days. It does not present the same imminent threat of death in minutes as a massive hemorrhage.
- Blood pressure of 160/100 mmHg: This finding indicates severe preeclampsia, which is often a precursor to HELLP syndrome. Severe hypertension requires urgent management to prevent maternal stroke or seizure. Nevertheless, in the presence of DIC, the immediate physiological crisis is the inability to clot. A hemorrhagic stroke from DIC is a more direct and immediate consequence of the coagulopathy than a hypertensive stroke, making the bleeding signs the priority.
- Proteinuria of 3+ on dipstick: This is a hallmark diagnostic criterion for preeclampsia with severe features. It reflects the pathophysiological process of glomerular capillary leak. While it confirms the severity of the preeclamptic process that likely triggered the HELLP syndrome, it is a diagnostic and monitoring parameter, not a direct indicator of an immediately life-threatening event. Its clinical consequences are chronic and progressive, not acutely fatal in the same way as DIC.
In summary, for a patient with HELLP syndrome who has developed DIC, the nurse’s priority is to recognize the shift from a state of risk to a state of active, systemic hemorrhage. The appearance of petechiae and ecchymoses is the sentinel physical sign of this critical transition, demanding immediate intervention to support coagulation and prevent fatal bleeding [1].

Clinical Priority in HELLP Syndrome with DIC
A 36-week gravid client with HELLP syndrome develops disseminated intravascular coagulation (DIC). The nurse must prioritize assessment findings that indicate the most immediate threat to life.
Pathophysiology Context
HELLP syndrome involves hemolysis, elevated liver enzymes, and thrombocytopenia. When DIC supervenes, the consumption of platelets and clotting factors leads to a paradoxical state of simultaneous microthrombi formation and systemic hemorrhage. The priority is to recognize findings that signal active, uncontrolled bleeding over organ-specific manifestations.
Prioritization Rationale
Petechiae and ecchymoses (Priority): These are direct clinical indicators of a severe bleeding diathesis. In the setting of known DIC, they signal that the patient is at immediate risk for life-threatening hemorrhage, including intracranial or intra-abdominal bleeding, which can rapidly lead to hypovolemic shock and death.
Decreased urine output (20 mL/hour): Indicates renal hypoperfusion or acute kidney injury, a serious complication of HELLP syndrome. However, its progression to irreversible damage is slower than the acute mortality risk from exsanguination in DIC.
Blood pressure 160/100 mmHg: Represents severe hypertension requiring prompt antihypertensive therapy to prevent maternal stroke or eclampsia. While urgent, it is managed concurrently and does not carry the same immediate mortality risk as active hemorrhage from DIC.
Proteinuria 3+: Reflects glomerular endotheliosis from preeclampsia/HELLP. It is a diagnostic and monitoring parameter, not an acute, life-threatening sign requiring immediate intervention over bleeding.
Nursing Implications
When DIC is suspected in a patient with HELLP syndrome, the nurse should immediately assess for signs of active bleeding (skin, mucous membranes, IV sites, surgical wounds) and monitor for occult hemorrhage (altered mental status, abdominal distension, tachycardia, hypotension). Prompt recognition and communication of these findings are critical for initiating transfusion protocols and preparing for potential emergent delivery.
HELLP syndrome — A pregnancy complication characterized by Hemolysis, Elevated Liver enzymes, and Low Platelet count, considered a severe variant of preeclampsia.
Disseminated Intravascular Coagulation (DIC) — An acquired disorder of coagulation where widespread clotting in small vessels consumes platelets and clotting factors, paradoxically leading to severe bleeding.
Petechiae and Ecchymoses — Pinpoint, non-blanching spots (petechiae) and larger bruises (ecchymoses) caused by bleeding under the skin, indicative of thrombocytopenia or coagulopathy.
Thrombocytopenia — A platelet count below the normal range, a hallmark of HELLP syndrome, which impairs the blood's ability to clot and increases bleeding risk.
