NCLEX Review Guide: Pediatric Hodgkin's Disease

Disease Overview

• Hodgkin's Disease is a malignant lymphoma characterized by the presence of Reed-Sternberg cells in lymph node tissue. It typically spreads in an orderly, predictable pattern from one lymph node group to adjacent groups.
• Peak incidence occurs in adolescents aged 15-19 years, with a second peak in adults over 55. Boys are affected more frequently than girls in pediatric cases.

Clinical Manifestations

• Painless lymphadenopathy is the most common presenting symptom, typically in the neck, axilla, or mediastinum. Nodes are firm, movable, and non-tender.
• B symptoms include fever >38°C (100.4°F), drenching night sweats, and unexplained weight loss >10% of body weight in 6 months - these indicate more advanced disease.
• Mediastinal involvement may cause superior vena cava syndrome with facial swelling, dyspnea, and orthopnea.

Diagnostic Workup

• Lymph node biopsy is the definitive diagnostic test, revealing characteristic Reed-Sternberg cells. Fine needle aspiration is inadequate for diagnosis.
• Staging includes CT scans of chest, abdomen, and pelvis, PET scan, bone marrow biopsy, and complete blood count with differential.

Treatment Modalities

• Treatment combines chemotherapy and radiation therapy based on staging. Common regimens include ABVD (Adriamycin, Bleomycin, Vinblastine, Dacarbazine).
• Radiation therapy in children requires careful consideration due to growth and development concerns, including potential cardiac and pulmonary toxicity.

Nursing Interventions

1. Monitor for infection - assess vital signs q4h, implement neutropenic precautions when ANC <1000, teach proper hand hygiene
2. Manage chemotherapy side effects - administer antiemetics prophylactically, monitor for mucositis, assess nutritional status
3. Provide psychosocial support - encourage age-appropriate coping strategies, facilitate peer interaction when possible
4. Monitor for tumor lysis syndrome - watch for hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia

Acute Complications

• Superior vena cava syndrome requires immediate intervention - position upright, administer oxygen, prepare for emergency radiation or chemotherapy.
• Tumor lysis syndrome prevention includes aggressive hydration, allopurinol administration, and electrolyte monitoring every 6-8 hours.

Late Effects

• Secondary malignancies may develop 10-20 years post-treatment, particularly breast cancer in females who received chest radiation.
• Cardiac toxicity from anthracyclines requires lifelong echocardiogram monitoring and lifestyle modifications to reduce cardiovascular risk factors.

NCLEX Success Strategies

• Remember that painless lymphadenopathy is the hallmark - if nodes are painful, consider other diagnoses first.
• B symptoms indicate systemic involvement and more advanced staging - this affects prognosis and treatment intensity.
