A nurse is assessing a postpartum client who delivered 6 hours ago and is suspected of having disseminated intravascular coagulation (DIC). Which assessment finding would be most indicative of DIC in this client?
1Elevated fibrinogen levels and increased platelet count
2Prolonged bleeding from venipuncture sites with petechiae and ecchymoses✓ 정답
3Hypertension with proteinuria and edema
4Decreased urine output with elevated creatinine levels
해설
DIC is characterized by simultaneous clotting and bleeding, leading to prolonged bleeding from sites like venipuncture with petechiae and ecchymoses. Other options represent findings not specific to DIC in postpartum.
Core Nursing ExplanationKey Concept Analysis: This question assesses the ability to recognize the clinical signs of Disseminated Intravascular Coagulation (DIC) in a postpartum patient. DIC is a life-threatening consumptive coagulopathy where widespread, abnormal clotting depletes clotting factors and platelets, leading to simultaneous thrombosis and hemorrhage. In obstetrics, it's a critical complication often triggered by conditions like placental abruption, amniotic fluid embolism, or severe preeclampsia.
Answer Rationale: Key Point! The hallmark of DIC is uncontrolled bleeding due to coagulation factor depletion. In a postpartum patient, this manifests as oozing from venipuncture sites, surgical incisions (episiotomy or C-section), or the uterus, along with petechiae (tiny red spots from capillary bleeding) and ecchymoses (bruises). These are direct signs of the body's inability to form stable clots.
Distractor Analysis:
Watch out for confusion! Option ① describes elevated fibrinogen and platelets. In DIC, the opposite occurs: fibrinogen and platelets are consumed, leading to decreased levels. This option describes a hypercoagulable state, not consumptive coagulopathy.
Option ③ describes the classic triad of preeclampsia (hypertension, proteinuria, edema), which can be a *cause* of DIC but is not a direct sign of DIC itself.
Option ④ indicates acute kidney injury (AKI), which can be a complication of DIC due to microthrombi blocking renal vessels, but it is a later, non-specific sign. The most indicative and early signs are the bleeding manifestations.
Related Concepts: Understanding DIC requires knowing its lab profile: Prolonged PT/PTT/INR, decreased fibrinogen, decreased platelets, and elevated D-dimer and Fibrin Degradation Products (FDPs). The primary nursing interventions focus on treating the underlying cause, administering blood products (like cryoprecipitate for fibrinogen, platelets), and monitoring for signs of bleeding and organ ischemia.
Concept Summary

Key Points
DIC Pathophysiology
Uncontrolled activation of clotting cascade → widespread microthrombi → consumption of clotting factors & platelets → hemorrhage.
Common Postpartum Triggers
Placental abruption, amniotic fluid embolism, severe preeclampsia/HELLP syndrome, sepsis, retained products of conception.
Anatomy, Physiology & Pharmacology PointsPhysiology: Normal hemostasis is a balance between clot formation (coagulation) and clot breakdown (fibrinolysis). DIC represents a catastrophic failure of this system. The widespread thrombin generation consumes factors I (fibrinogen), II, V, VIII and platelets.
Pharmacology: Treatment is supportive and causal. Cryoprecipitate provides fibrinogen. Fresh Frozen Plasma (FFP) replaces all clotting factors. Platelet transfusions are given for severe thrombocytopenia. Heparin is controversial and used only in specific cases of predominant thrombosis (e.g., cancer-related DIC).
Memory TipsAcronym for DIC Lab Findings: "Platelets Down, Fibrinogen Down, D-dimer Up" (PDF-DU).
Clinical Picture: Think "Bleeding from everywhere" – gums, IV sites, incisions, urine, under the skin (petechiae).
High-Frequency NCLEX Topics
DIC is a High-Yield emergency topic. The NCLEX loves to test: 1) Recognizing the most indicative signs (bleeding manifestations), 2) Knowing the common obstetric triggers, and 3) Prioritizing nursing actions (e.g., monitoring for hemorrhage, administering blood products as ordered, frequent vital signs).
Watch Out for Question Variations!
* From Signs to Cause: "A postpartum client with DIC is most likely experiencing which underlying condition?" (Answer: Placental abruption).
* From Assessment to Lab: "Which lab result would the nurse anticipate for a client with DIC?" (Answer: Decreased fibrinogen).
* Priority Intervention: "The nurse's priority action for a postpartum client with suspected DIC is to..." (Answer: Assess for and control active bleeding, notify the provider immediately).
Nursing Clinical Practice GuideClinical Scenario: You are caring for Ms. Lopez, G2P2, who had a vaginal delivery 5 hours ago following a prolonged labor. She had a history of preeclampsia. You notice her perineal pad is saturated every 30 minutes with bright red blood, she has new petechiae on her chest, and the IV site from her labor epidural is oozing.
Nursing Intervention Strategy:
1Immediate Assessment (ABCs)Assess vital signs for tachycardia and hypotension (signs of hypovolemic shock). Perform a focused assessment: check all potential bleeding sites (IV sites, gums, incision, uterus - fundal check), and skin for petechiae/ecchymosis.
2Notify & CollaborateImmediately notify the obstetrician and charge nurse. Prepare for stat labs: CBC with platelet count, coagulation panel (PT/PTT/INR, fibrinogen), D-dimer.
3Implement Supportive Care* Bleeding Control: Maintain firm fundal massage if uterus is boggy. Apply direct pressure to oozing IV sites.
* Monitor & Document: Quantify blood loss (weigh pads). Monitor oxygen saturation and urine output hourly (indicator of renal perfusion).
* Prepare for Treatment: Anticipate orders for IV access with large-bore catheters, fluid resuscitation, and blood product administration (FFP, cryoprecipitate, platelets).
Patient Safety and Precautions:
* Avoid Trauma: Handle the patient gently. Avoid unnecessary injections, IM medications, or rectal temps. Use soft-bristle toothbrushes.
* Medication Caution: Do not administer heparin or antiplatelet drugs unless specifically ordered for a rare form of DIC. Be vigilant when giving any IM injection.
* Monitor for Complications: Watch for signs of organ failure from microthrombi: altered mental status (CNS), chest pain/dyspnea (pulmonary), oliguria (renal), abdominal pain (GI/hepatic).
Nursing Procedure & Medication FlowAdministering Blood Products for DIC:
1VerificationDouble-check the order and product with another nurse per protocol.
2TimingAdminister cryoprecipitate and plateletsrapidly (as fast as tolerated) to quickly replete clotting factors. FFP may need to be thawed first.
3MonitoringMonitor for transfusion reactions. More importantly, reassess bleeding signs and repeat coagulation labs post-transfusion to evaluate effectiveness.
A Word from Your Senior Nurse
"DIC is one of the scariest 'medical' emergencies in postpartum nursing because it happens fast and the patient can bleed from places you don't expect. Your eyes and hands are your best tools. When you see that combination of a saturated pad, oozing IV site, and little red dots on the skin, your brain must scream 'DIC!' and you must act immediately. On the NCLEX, they test if you know the classic picture. In real life, recognizing that picture early and calling the team can save a mother's life. Always connect the dots: abnormal bleeding + a high-risk obstetric history = think coagulopathy."
