Match the following: 679. Vincristine

Correct Answer: C

Rationale: Vincristine, a vinca alkaloid, causes peripheral neuropathy, myopathy (C) microtubule inhibition affects nerves, muscles (e.g., foot drop). Myelosuppression (A) is methotrexate. Protein defects (B) fit asparaginase. Cystitis (D) is cytoxan. Psychosis is prednisone. Vincristine's neurotoxicity is key in nursing for dose monitoring and neuropathy assessment.

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).

Correct Answer: D

Rationale: Anemia of hepatic disease blood loss, folate deficiency, alcohol (D) cause it (e.g., varices, poor diet, toxicity), yielding normocytic/macrocytic anemia. Iron block (A) is chronic. EPO (B) is renal. Normocytic (C) is effect. Multifactorial etiology is key, guiding nursing for liver function and folate.
