Match the following: 663. Superior vena caval syndrome

Correct Answer: A

Rationale: Superior vena caval syndrome (SVCS) SVC obstruction shows collateral vessels (A), dilated chest veins (e.g., from lung cancer compression). Tracheal perforation (B) is traumatic, unrelated. Elderly debilitation (C) isn't specific. Collaterals bypass blockage, key in nursing for recognizing malignancy-driven SVCS, prompting radiotherapy.

Correct Answer: C

Rationale: Sternal tenderness marks acute leukemia (C) marrow infiltration (e.g., blasts >20%) causes bone pain, palpable on percussion. Rheumatoid arthritis (A) spares marrow. Mononucleosis (B) lacks bone involvement. Endocarditis (D) affects heart. Leukemia's marrow crowding is key, guiding nursing for marrow aspiration and chemotherapy prep.

Correct Answer: B

Rationale: Sickle cell anemia crises yield recovery with recurrence (B) vaso-occlusion (e.g., pain, HbS polymerization) resolves with hydration, oxygen, but HbS persists, risking repeat (e.g., 50% recur yearly). Complete recovery (A) ignores chronicity. Splenectomy (C) is HS, not sickle. Infection (D) or aplastic crisis kills, but most recover from vaso-occlusive events. Recurrence is key, guiding nursing for analgesia and trigger avoidance.

Correct Answer: D

Rationale: Multiple myeloma features nitrogen retention (A renal failure), hypercalcemia (C bone lysis), proteinuria (D Bence-Jones), but not glucosuria glucose isn't excreted unless diabetic, unrelated to plasma cell dyscrasia. Hypoproteinemia (B) is rare hypergammaglobulinemia dominates. Glucosuria's absence is key, guiding nursing for renal function and calcium monitoring.

Correct Answer: D

Rationale: Hemosiderin (D) iron-storing pigment accumulates in tissues (e.g., liver, spleen) from RBC breakdown, staining blue on Prussian blue. Urobilinogen (A), bilirubin (B), hematoidin (C) heme metabolites lack iron, excreted or reabsorbed. All' overstates. Hemosiderin's iron link is key, guiding nursing for overload monitoring (e.g., hemochromatosis).
