Questions on Respiratory System Questions
Question 1 of 5
Match the following: 656. chylothorax
Correct Answer: C
Rationale: Chylothorax milky pleural fluid results from thoracic duct rupture (C), often traumatic or malignant, leaking lymph (high triglycerides, >110 mg/dL). Friction rub (A) is pleuritis. CHF (B) gives transudate. Pseudomonas (D) ties to empyema. Bleb causes pneumothorax. Duct injury's lymphatic spill is distinct, key in nursing for drainage or surgical consult.
Question 2 of 5
Which of the following is not correct concerning aplastic anemia:
Correct Answer: C
Rationale: Aplastic anemia marrow failure lacks usually associated with splenomegaly' (C); spleen enlarges in hemolysis, not aplasia pancytopenia (low platelets, B) reflects marrow hypoplasia (D), often drug-induced (A, e.g., chloramphenicol) or idiopathic (E, 50%). C's falsehood contrasts aplasia's etiology, key in nursing for avoiding splenomegaly confusion and focusing on transfusion or transplant.
Question 3 of 5
In which of these disease is there not a high incidence of peptic ulcer:
Correct Answer: C
Rationale: Pulmonary emphysema lacks a high peptic ulcer incidence no direct mechanism links obstructive lung disease to gastric ulceration. Cirrhosis (A) increases ulcers via portal hypertension or coagulopathy. Cushing's (B) raises cortisol, eroding mucosa. Hyperparathyroidism (C) boosts acid via hypercalcemia. Pernicious anemia (D) ties to gastritis, not ulcers directly. Emphysema's respiratory focus spares GI, key in nursing for differential symptom management e.g., dyspnea vs. epigastric pain.
Question 4 of 5
In contemporary transfusion practice, the commonest cause of life threatening reaction is:
Correct Answer: C
Rationale: ABO incompatibility (C) is the commonest life-threatening transfusion reaction mismatched antigens (e.g., A to O) cause acute hemolysis (e.g., Hb drop, renal failure), with 1:40,000 risk. Contamination (A) is rare with screening. Rh (B) or WBC reactions are milder. Allergy (D) is non-hemolytic. ABO's severity is key, guiding nursing for crossmatch checks and reaction management.
Question 5 of 5
All but one of the following concerning iron metabolism are true:
Correct Answer: C
Rationale: Iron metabolism true: stored as hemosiderin/ferritin (A), transported by transferrin (B), slow depletion (D e.g., 3-5 years), diurnal variation (E e.g., 120 vs. 90 μg/dL) but C is false: ferrous (Fe²âº) absorbs better than ferric (Fe³âº), reduced in gut. C's error is key, guiding nursing for ferrous sulfate therapy.
