Pernicious anemia is associated with all of the following, except:

Correct Answer: B

Rationale: Pernicious anemia lacks normal intrinsic factor (B) autoimmune gastric atrophy blocks IF, causing B12 deficiency (D), yielding macrocytic anemia (E MCV >100 fL), sore tongue (A glossitis), and neuropathy (C subacute combined degeneration). B's normality negates the disease, key in nursing for Schilling test and B12 injections.

Correct Answer: B

Rationale: Secondary polycythemia hypoxia-driven RBC rise occurs in hypernephroma (A erythropoietin), emphysema (C low Oâ‚‚), AV aneurysms (D shunting), and cyanotic heart disease (E chronic hypoxia), but not peptic ulcer (B) GI bleeding causes anemia, not polycythemia. Hypoxia's erythropoietic trigger is key, guiding nursing for underlying cause workup.

Correct Answer: B

Rationale: Hemophilia joint bleed (e.g., factor VIII <1%) fresh frozen plasma (B) replaces clotting factors (e.g., 15 mL/kg raises VIII to 30%), stopping hemarthrosis. Transfusion (A) lacks factors. Bed rest (C) aids, not treats. Vitamin K (D) is for liver factors. Protamine reverses heparin. FFP's factor delivery is key, guiding nursing for infusion and joint care.

Correct Answer: B

Rationale: Anemia of renal insufficiency low erythropoietin (B e.g., <100 mU/mL) from kidney failure slows RBC production, with reduced marrow transit (e.g., 5-7 days). Iron block (A) is chronic disease. Normocytic (C) describes, not causes. Blood loss (D) is unrelated. EPO deficiency is key, guiding nursing for EPO therapy.
