📚 Hemophilia — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Hemophilia is an X-linked recessive inherited bleeding disorder caused by a deficiency of a clotting factor. Hemophilia A is factor VIII deficiency (most common) and hemophilia B (Christmas disease) is factor IX deficiency. It almost always affects males, with females being carriers. The hallmark is deep bleeding into joints (hemarthrosis) and muscles, and prolonged bleeding after injury or surgery.
🔑
Key points
Understand these first
X-linked recessive: males affected, females are carriers; type A = factor VIII deficiency, type B = factor IX deficiency.
Hemarthrosis (bleeding into joints, especially knees, elbows, ankles) causes pain, swelling, warmth, and can lead to chronic joint damage.
Platelet count and PT are normal; aPTT is prolonged because the intrinsic pathway factors are deficient.
Treatment is IV replacement of the deficient clotting factor (factor VIII or IX concentrate); desmopressin (DDAVP) raises factor VIII in mild hemophilia A.
Bleeding is not faster but is prolonged and harder to stop; prolonged oozing after dental work or circumcision is a common early sign.
Aminocaproic acid may be used adjunctively to stabilize clots, especially for mucosal or oral bleeding.
✅
Nursing priorities
What to do, in order
Control active bleeding: apply firm direct pressure, ice, immobilize and elevate the affected joint or limb.
Administer prescribed clotting factor concentrate IV; have it readily available before any invasive procedure.
Implement bleeding precautions: avoid IM injections, use the smallest gauge needle, hold venipuncture sites longer.
Assess joints for hemarthrosis (pain, swelling, limited motion) and monitor for signs of internal or intracranial bleeding.
Provide RICE (rest, ice, compression, elevation) and pain control with acetaminophen rather than aspirin or NSAIDs.
🚩
Red flags — report now
Escalate immediately
Headache, vomiting, confusion, or decreased level of consciousness signal possible intracranial hemorrhage; report and treat immediately.
Never give aspirin, NSAIDs, or other antiplatelet/anticoagulant drugs as they worsen bleeding.
Avoid IM injections and rectal temperatures; signs of airway compromise from neck or throat bleeding require emergent attention.

Labs & values
Numbers to know
aPTT: prolonged (normal 30-40 sec)
PT/INR: normal
Platelet count: normal (150,000-400,000/mm3)
Bleeding time: normal
Factor VIII or IX assay: decreased

Patient teaching
What patients must know
Teach factor replacement administration and to infuse at the first sign of bleeding (early treatment limits joint damage).
Avoid contact sports and high-injury activities; choose swimming or other low-impact exercise to protect joints.
Use a soft toothbrush and electric razor; avoid aspirin and NSAIDs, reading OTC labels carefully.
Wear medical alert identification and inform all providers and dentists of the diagnosis before procedures.
Genetic counseling is recommended; female carriers may pass the gene to offspring.
❓ Hemophilia: NCLEX FAQs
What are the priority nursing interventions for Hemophilia?
Control active bleeding: apply firm direct pressure, ice, immobilize and elevate the affected joint or limb. Administer prescribed clotting factor concentrate IV; have it readily available before any invasive procedure. Implement bleeding precautions: avoid IM injections, use the smallest gauge needle, hold venipuncture sites longer. Assess joints for hemarthrosis (pain, swelling, limited motion) and monitor for signs of internal or intracranial bleeding.
What are the warning signs of Hemophilia a nurse must report?
Headache, vomiting, confusion, or decreased level of consciousness signal possible intracranial hemorrhage; report and treat immediately. Never give aspirin, NSAIDs, or other antiplatelet/anticoagulant drugs as they worsen bleeding. Avoid IM injections and rectal temperatures; signs of airway compromise from neck or throat bleeding require emergent attention.
