Thrombocytopenia
This is the most important nursing intervention for a hospitalized patient with a platelet count of 18,000.
What is implementing strict bleeding precautions?
Rationale:
A platelet count <20,000 places the patient at high risk for spontaneous bleeding, including intracranial hemorrhage. Priority interventions include: no invasive procedures, soft toothbrush, no rectal temps, fall prevention, and avoiding NSAIDs.
This medication is never given to treat ITP because the patient will rapidly destroy it.
What is a platelet transfusion?
Rationale:
In ITP, platelets are destroyed by autoantibodies. Transfused platelets are immediately attacked unless the patient is actively hemorrhaging. First‑line treatments are steroids, IVIG, rituximab, or splenectomy.
This dangerous complication of heparin therapy causes a drop in platelets but a rise in clotting risk.
What is Heparin‑Induced Thrombocytopenia (HIT)?
Rationale:
HIT is a pro‑thrombotic immune reaction where antibodies activate platelets, causing clots, not bleeding. Platelets fall by >50% from baseline. This paradox—low platelets but high clot risk—is a classic exam point.
This life‑threatening condition is characterized by simultaneous microclotting and massive bleeding due to depletion of clotting factors and platelets
What is disseminated intravascular coagulation (DIC)?
Rationale:
DIC begins with widespread clotting, which consumes platelets and fibrinogen, leading to uncontrolled bleeding. It is always secondary to another condition (sepsis, trauma, obstetric complications).
This IV fluid is the only one that can be infused with blood products
What is 0.9% normal saline?
Rationale:
NS is isotonic and does not cause hemolysis. LR contains calcium → risk of clotting. Dextrose causes RBC lysis. This is one of the most frequently tested blood‑product safety questions.
These three integumentary findings are classic signs of severe thrombocytopenia.
What are petechiae, purpura, and ecchymosis?
Rationale:
Low platelets impair clot formation, causing capillary fragility and bleeding into the skin. These are hallmark exam findings and often appear before internal bleeding is detected.
This autoimmune condition causes platelet destruction in the spleen despite normal bone marrow production
What is Immune Thrombocytopenic Purpura (ITP)?
Rationale:
ITP is caused by IgG autoantibodies that bind to platelets, marking them for destruction in the spleen. Bone marrow production is normal or increased, but platelets are destroyed faster than they can be replaced.
This medication is the immediate replacement for heparin when HIT is diagnosed
What is argatroban?
Rationale:
Argatroban is a direct thrombin inhibitor used to prevent thrombosis in HIT. Heparin must be stopped immediately, and platelets are NOT transfused unless life‑threatening bleeding occurs. Warfarin is avoided until platelets recover.
These subtle symptoms—often the earliest signs of DIC—may appear at IV sites, gums, or wounds
What is oozing or mild bleeding?
Rationale:
Oozing from venipuncture sites is often the first visible sign of DIC. It progresses to petechiae, ecchymosis, hematuria, GI bleeding, and organ ischemia.
These are the first three symptoms a nurse typically sees in an acute hemolytic transfusion reaction
What are fever, chills, and low back/flank pain?
Rationale:
Hemolysis releases free hemoglobin → kidney injury → flank pain. Fever and chills are the earliest signs. This is a life‑threatening emergency requiring immediate action.
These are the three major pathophysiologic causes of thrombocytopenia.
What are decreased platelet production, increased platelet destruction, and platelet sequestration?
Rationale:
the triad for thrombocytopenia. Examples:
Decreased production: leukemia, chemo, aplastic anemia
Increased destruction: ITP, HIT, DIC
Sequestration: splenomegaly
This first‑line medication is used to rapidly increase platelet counts in ITP by decreasing immune‑mediated platelet destruction
What are corticosteroids?
Rationale:
Steroids (e.g., prednisone, dexamethasone) suppress the immune system, reducing antibody‑mediated platelet destruction. They are the first‑line treatment for newly diagnosed ITP.
This acronym describes a life‑threatening pregnancy complication involving hemolysis, elevated liver enzymes, and low platelets
What is HELLP syndrome?
Rationale:
HELLP is a severe form of preeclampsia. It causes hemolysis, liver injury, and thrombocytopenia, leading to high maternal and fetal mortality if not treated promptly.
In DIC, these two labs are elevated, while these two are decreased
What are: Elevated D‑dimer and PT/aPTT, and decreased fibrinogen and platelets?
Rationale:
D‑dimer rises due to fibrin breakdown. PT/aPTT prolong due to factor depletion. Fibrinogen and platelets drop because they are consumed in microclotting.
This is the very first action the nurse must take when a transfusion reaction is suspected
What is stop the transfusion?
Rationale:
Stopping the transfusion prevents further exposure to the incompatible blood. Then: maintain IV with NS, notify provider/blood bank, save tubing/bag, obtain labs. Stopping the transfusion is ALWAYS the first step.
This life‑threatening complication must be monitored for in any patient with thrombocytopenia who becomes confused, lethargic, or complains of a severe headache
What is intracranial hemorrhage?
Rationale:
A sudden change in LOC is an emergency in thrombocytopenia. Platelet counts below 10,000 dramatically increase the risk of spontaneous brain bleeding. Immediate neuro assessment and provider notification are required.
This is the reason platelet transfusions are not routinely given in ITP unless the patient is actively hemorrhaging
What is rapid immune destruction of transfused platelets?
Rationale:
In ITP, autoantibodies attack all platelets, including transfused ones. Transfusions are ineffective unless the patient is in life‑threatening bleeding, where temporary support is needed while other treatments (IVIG, steroids) take effect.
This is the only cure for HELLP syndrome
What is delivery of the baby?
Rationale:
HELLP is a pregnancy‑related condition. Stabilization (magnesium, antihypertensives, blood products) may be needed, but delivery is the definitive treatment to prevent maternal organ failure or DIC.
This is the most important action to improve survival in a patient with DIC
What is treating the underlying cause?
Rationale:
DIC is always secondary—sepsis, trauma, HELLP, placental abruption, malignancy, transfusion reaction. Replacing blood products helps temporarily, but fixing the cause is the only way to stop the cycle.
This blood type is the universal donor for packed red blood cells
What is O negative?
Rationale:
O‑ has no A/B antigens and no Rh antigen, so it will not trigger an immune response in recipients. This is a classic exam question.
“This medication is given to a patient with hepatic encephalopathy and thrombocytopenia, not to raise platelets, but to prevent a complication that can worsen bleeding risk
What is lactulose?
Rationale:
Lactulose reduces ammonia levels by promoting its excretion through the GI tract. High ammonia → worsening encephalopathy → decreased LOC → increased fall risk → increased bleeding risk in thrombocytopenia. It does not improve platelet count, but it prevents neurological decline that could lead to trauma or hemorrhage. Expected outcome: 2–3 soft stools/day, not diarrhea.
This serious complication must be monitored for in ITP patients with platelets <10,000, especially if they report a sudden severe headache
What is intracranial hemorrhage?
Rationale:
Platelet counts below 10,000 significantly increase the risk of spontaneous bleeding, especially in the brain. A sudden headache, confusion, vomiting, or neurological changes require immediate emergency evaluation.
A patient with HELLP syndrome who reports right upper quadrant pain and nausea is at risk for this life‑threatening complication
What is liver rupture?
Rationale:
RUQ or epigastric pain in HELLP indicates liver swelling or subcapsular hematoma, which can rupture and cause massive internal bleeding. This is an obstetric emergency requiring immediate intervention.
This organ‑threatening complication occurs when microclots impair perfusion, leading to rising creatinine and decreased urine output
What is acute kidney injury (AKI)?
Rationale:
Microthrombi obstruct renal circulation, causing renal ischemia. AKI is a major cause of mortality in DIC and requires close monitoring of urine output and creatinine.
This is the primary lab value the nurse monitors to determine the effectiveness of FFP administration
What is PT/INR?
Rationale:
FFP replaces clotting factors, so PT/INR should improve (decrease) after infusion. FFP is used for warfarin reversal, liver failure, and DIC with bleeding.
