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.
Core Nursing ExplanationKey Concept Analysis: This question integrates two critical, life-threatening obstetric complications: HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) and its progression to Disseminated Intravascular Coagulation (DIC). DIC is a paradoxical state of simultaneous, uncontrolled clotting and bleeding. The body's clotting mechanisms are hyperactivated, consuming platelets and clotting factors to form microthrombi throughout the vasculature. This leads to Key Point! a critical depletion of these components, resulting in a profound hemorrhagic diathesis (bleeding tendency). The priority in DIC is managing the bleeding, which can lead to hypovolemic shock, organ ischemia, and death.
Answer Rationale: Key Point!Petechiae and ecchymoses are direct, visible signs of the underlying pathophysiology of DIC—severe thrombocytopenia (low platelets) and clotting factor deficiency. These findings indicate spontaneous bleeding into the skin and mucous membranes, which can rapidly progress to internal bleeding (e.g., intracranial, retroperitoneal, GI). In the context of a pregnant patient, this also signals a high risk for catastrophic obstetric hemorrhage during or after delivery. Therefore, this assessment finding represents the most immediate threat to the patient's life and is the nurse's priority concern.
Distractor Analysis:
Option 1 (Decreased urine output): While oliguria (20 mL/hour) is a serious sign of renal impairment, often seen in severe preeclampsia/HELLP due to reduced perfusion, it is a consequence of the disease process. In the acute setting of Watch out for confusion!active DIC, uncontrolled bleeding takes precedence as it can directly and rapidly cause hypovolemic shock and multi-organ failure, including renal failure.
Option 3 (Elevated BP): Hypertension (160/100 mmHg) is a hallmark of the underlying preeclampsia/HELLP syndrome. It requires management to prevent complications like stroke (eclampsia). However, in the specific context of a patient who has developed DIC, the hemorrhagic crisis becomes the more immediate, life-threatening issue.
Option 4 (Proteinuria): 3+ proteinuria is a diagnostic criterion for preeclampsia and indicates glomerular endothelial damage. Like hypertension, it reflects the severity of the preeclamptic state but is not an acute manifestation of the superimposed DIC coagulopathy.
Related Concepts: The nursing priority follows the ABCs (Airway, Breathing, Circulation) and Maslow's Hierarchy of Needs. Uncontrolled bleeding directly threatens Circulation (and ultimately Airway/Breathing via shock), placing it at the highest priority level. Management of DIC involves treating the underlying cause (often delivery of the fetus), replacing consumed clotting factors and platelets with blood products (fresh frozen plasma, cryoprecipitate, platelets), and supportive care.

Anatomy, Physiology & Pharmacology Points
Pathophysiology: In obstetric DIC, placental release of thromboplastic substances triggers the intrinsic coagulation cascade. Fibrin clots form in small vessels, damaging RBCs (schistocytes seen on smear), obstructing blood flow (causing organ ischemia), and consuming platelets & Factors I (fibrinogen), II, V, VIII.
Treatment: Definitive treatment is delivery of fetus/placenta. Supportive treatment includes transfusion of Fresh Frozen Plasma (FFP) (replaces clotting factors), Cryoprecipitate (rich in fibrinogen), and Platelets. Heparin is contraindicated in obstetric DIC.
Memory Tips
DIC Priority = "Bleed Before Pressure": In a patient with DIC, address bleeding manifestations (petechiae) before focusing on blood pressure issues (which may be high from preeclampsia or low from bleeding).
HELLP to DIC Progression: Think "Hemolysis uses up RBCs, Low Platelets get even lower, leading to DIC." The bleeding risk escalates dramatically.
High-Frequency NCLEX Topics
NCLEX loves testing priority-setting in complex, multi-problem patients. A pregnant patient with combined preeclampsia/HELLP and DIC is a classic high-acuity scenario. Remember: Airway, Breathing, Circulation (Bleeding!) always comes first. The exam will often present several abnormal findings; you must identify which one indicates the most immediate threat to life.
Watch Out for Question Variations!
Shift from Assessment to Intervention: "The nurse notes petechiae in a patient with HELLP syndrome and suspected DIC. What is the priority nursing action?" (Answer: Notify the provider immediately, prepare for possible blood product administration, monitor for signs of internal bleeding).
Shift to Lab Values: "Which laboratory result would the nurse anticipate being most critically low in a patient with HELLP syndrome who develops DIC?" (Answer: Platelet count and Fibrinogen level).
Shift to Postpartum: The same principles apply to postpartum patients who develop DIC from other causes (e.g., amniotic fluid embolism, sepsis).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on the Labor & Delivery unit. Maria, a 36-week gestation G1P0, was admitted with severe headache and epigastric pain. Her labs confirmed HELLP syndrome. Suddenly, you notice new, pinpoint red spots (petechiae) on her chest and arms and a large purple bruise (ecchymosis) at her IV site. Her blood pressure is 158/102 mmHg.
Nursing Intervention Strategy:
Immediate Assessment & Notification: Your first action is to recognize these as signs of worsening coagulopathy, likely DIC. Perform a rapid but thorough assessment: check all IV sites, gums, nose for bleeding; assess vaginal bleeding; perform a neuro check (risk of intracranial hemorrhage). Immediately notify the obstetrician and anesthesia team. This is a "STAT" situation.
Monitoring & Safety:
Vital Signs & Hemodynamics: Monitor BP, heart rate, and oxygen saturation continuously or every 5-15 minutes. Tachycardia and hypotension may indicate concealed hemorrhage.
Bleeding Precautions: Handle the patient gently. Avoid unnecessary injections, IM medications, or rectal temps. Use the smallest gauge needle for IV access. Apply prolonged pressure (5-10 minutes) after any venipuncture.
Intake & Output (I&O): Insert an indwelling urinary catheter to monitor hourly urine output closely. Oliguria can signal hypovolemia from bleeding or renal failure.
Prepare for Intervention:
Laboratory: Draw stat labs per protocol: CBC, coagulation panel (PT/PTT, fibrinogen, D-dimer), liver enzymes, chemistry.
Blood Products: Ensure blood samples for type and crossmatch have been sent. Anticipate and prepare for the administration of platelets, FFP, and/or cryoprecipitate as ordered.
Delivery: The definitive treatment is delivery. Prepare the patient for possible emergency cesarean section. Ensure informed consent is obtained rapidly.
Patient Safety and Precautions:
Do NOT administer heparin or any anticoagulant. This would worsen the bleeding in obstetric DIC.
Magnesium Sulfate: The patient will likely be on a MgSO4 infusion for seizure prophylaxis. Monitor closely for signs of magnesium toxicity (loss of deep tendon reflexes, respiratory depression) as renal function may be compromised.
Communication: Keep the patient and family informed in a calm, clear manner. Explain that she is being closely monitored and the team is acting quickly to keep her and her baby safe.
Nursing Procedure & Medication FlowManaging Blood Product Administration in DIC:
Verification: Perform a rigorous two-nurse verification of the blood product against the physician's order and the patient's identification.
Administration:
Platelets: Infuse rapidly, usually over 15-30 minutes. Use a standard blood transfusion set.
Fresh Frozen Plasma (FFP): Thawed FFP must be infused within 24 hours. Infuse as ordered, typically over 30-60 minutes.
Cryoprecipitate: Infuse rapidly, usually within 30 minutes.
Monitoring: Monitor for transfusion reactions (fever, chills, urticaria, dyspnea) and for clinical response (decreased bleeding, stabilization of vital signs).
A Word from Your Senior Nurse
"Seeing those first petechiae on a preeclamptic patient is one of the most heart-dropping moments in obstetric nursing. It's the visual cue that tells you the situation is escalating from serious to critical. In these moments, your knowledge is your power. You're not just charting a bruise; you're connecting the dots between pathophysiology and imminent risk. Your rapid, accurate assessment and communication set the entire emergency team in motion. This is why we drill on priorities—because in real life, there's no time to hesitate. When you study, always ask yourself, 'What would kill my patient first?' That's the lens you need for the NCLEX and for the bedside."
Disseminated Intravascular Coagulation — A life-threatening condition characterized by systemic activation of coagulation, leading to widespread microvascular thrombosis and simultaneous consumption of platelets and clotting factors, resulting in hemorrhage.
HELLP Syndrome — A severe variant of preeclampsia characterized by Hemolysis, Elevated Liver enzymes, and Low Platelet count. It is a medical and obstetric emergency.
Thrombocytopenia — A condition characterized by an abnormally low platelet count (<150,000/mm³), increasing the risk of bleeding. In HELLP/DIC, it results from platelet consumption and destruction.
Petechiae — Pinpoint, non-blanchable red or purple spots on the skin or mucous membranes caused by intradermal capillary bleeding, often a sign of severe thrombocytopenia or capillary fragility.
Ecchymosis — A larger, bruise-like area of bleeding under the skin, resulting from the escape of blood into the tissues from ruptured blood vessels. A common sign of bleeding disorders.
