Questions for Respiratory System Questions
Question 1 of 5
Match the following: 658. empyema
Correct Answer: D
Rationale: Empyema pus in pleura often involves Pseudomonas aeruginosa (D), a gram-negative bacillus in nosocomial or post-pneumonia infections, requiring drainage/antibiotics. Friction rub (A) fits pleuritis. CHF (B) gives transudate. Duct rupture (C) is chylothorax. Bleb is pneumothorax. Pseudomonas's purulence distinguishes empyema, key in nursing for chest tube management.
Question 2 of 5
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.
Question 3 of 5
The cell in the body most sensitive to radiation is:
Correct Answer: D
Rationale: Lymphocytes (D) are most radiation-sensitive rapidly dividing, they die at low doses (e.g., 1-2 Gy), dropping counts within days (e.g., <1000/μL). Erythrocytes (A) lack nuclei, resisting damage. Basophils (B), eosinophils (C), and granulocytes (E neutrophils) tolerate higher doses, declining later. Lymphocytes' vulnerability reflects marrow suppression, key in nursing for radiation exposure monitoring and infection prophylaxis.
Question 4 of 5
Secondary polycythemia is seen in all of the following, except:
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.
Question 5 of 5
The treatment of choice in a hemophilic bleeding into a knee joint would be:
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.
