Hemophilia

Key Points

• Hemophilia is an inherited X-linked bleeding disorder with reduced clotting factor VIII or IX.
• Spontaneous bleeding, especially in joints, and severe post-trauma bleeding are major safety risks.
• Weight management and joint-protection planning reduce bleed-trigger burden over time.
• Iron-status support is important because recurrent blood loss can worsen anemia risk.

Pathophysiology

Hemophilia reflects reduced coagulation-factor activity in the intrinsic pathway, most commonly factor VIII (hemophilia A) or factor IX (hemophilia B). Decreased factor availability impairs stable clot formation, increasing spontaneous and trauma-related bleeding.

Recurrent musculoskeletal bleeding can worsen pain, mobility limits, and long-term joint damage. Low activity used to avoid injury may promote weight gain, which increases joint stress and can further amplify bleeding-related functional decline.

Classification

• Hemophilia A pattern: Reduced factor VIII activity.
• Hemophilia B pattern: Reduced factor IX activity.
• Bleeding-risk pattern: Spontaneous joint bleeding and prolonged bleeding after injury or procedures.

Nursing Assessment

NCLEX Focus

Prioritize early recognition of bleeding burden and functional decline from recurrent joint involvement.

• Assess for spontaneous bleeding signs, especially hemarthrosis and persistent mucosal bleeding.
• Assess injury history and post-trauma bleed duration/intensity.
• Assess weight trend and activity pattern because sedentary avoidance behavior can worsen musculoskeletal stress.
• Assess dietary intake for iron-rich foods and vitamin C pairing when chronic blood-loss risk is present.
• Trend hemoglobin and iron-related laboratory values when bleeding burden increases.

Nursing Interventions

• Reinforce bleeding-risk reduction and joint-protection strategies in daily activity planning.
• Coordinate nutrition teaching focused on iron-rich foods (for example lean meats, leafy greens, legumes, grains, raisins) with vitamin-C-rich intake to support absorption.
• Support healthy-weight planning to reduce joint loading and bleed-trigger risk.
• Encourage safe, individualized activity rather than complete inactivity to preserve function.
• Escalate promptly for suspected internal bleeding or uncontrolled post-trauma bleeding.

Bleeding Escalation

New severe joint pain/swelling, persistent bleeding, or neurologic symptoms require urgent reassessment.
