Questions on Respiratory System Questions
Question 1 of 5
A well developed male had on routine examination an RBCs of 8 million, hemoglobin of 18 grams, hematocrit of 61, with normal leucocytes, thrombocytes & O2 saturation. There was no splenic enlargement. What test might give a clue to the probable diagnosis:
Correct Answer: C
Rationale: For polycythemia (RBC 8M, Hb 18 g/dL, Hct 61%), intravenous pyelogram (C) clues diagnosis renal tumors (e.g., hypernephroma) cause secondary polycythemia via erythropoietin, no splenomegaly fits. Splenic aspirate (A) targets primary PV. Scalene biopsy (B) checks lymphoma. LE test (D) is lupus, unrelated. Bronchoscopy assesses lung. IVP screens renal etiology, key in nursing for imaging prep and erythropoietin assay.
Question 2 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 3 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 4 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.
Question 5 of 5
The treatment of stage 1 Hodgkin's disease is:
Correct Answer: A
Rationale: Stage I Hodgkin's single node region treats with intensive irradiation (A e.g., 36 Gy), curing 90% by targeting lymphoma (e.g., mantle field). Surgery (B) is diagnostic. Chemo (C) is for advanced stages. None' (D), transfusion unfit. Radiation's efficacy is key, guiding nursing for planning and skin care.
