Hodgkin lymphoma arises from abnormal lymphocytes, most often B-cell lineage. In classic Hodgkin lymphoma, malignant Reed-Sternberg cells exist within an inflammatory background of immune cells. Disease commonly begins in lymph nodes above the diaphragm, especially cervical, supraclavicular, or mediastinal nodes, and tends to spread in a more predictable contiguous pattern than many non-Hodgkin lymphomas. Key concept: the tumor burden is not only malignant cells. Much of the lymph node enlargement comes from the inflammatory microenvironment surrounding the Reed-Sternberg cells. For Canadian NP practice / CNPLE-aligned preparation (Canada), items rarely announce the topic in the first sentence. Anchor to objective data, trajectory, and the safest next step for the role named in the stem before distractors compete. On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers even when the clinical topic is familiar. Run a 60-second scan: breathing work and oxygenation, perfusion and end organs, neuro baseline, likely infection sources, and devices that can fail quietly. When...
