Questions on the Respiratory System Questions
Question 1 of 5
Match the following: 657. pleuritis
Correct Answer: A
Rationale: Pleuritis pleural inflammation produces friction rub (A), a creaking sound from inflamed surfaces (e.g., pneumonia, TB). CHF (B) causes effusion, not rub. Duct rupture (C) yields chylothorax. Pseudomonas (D) links to empyema. Bleb is pneumothorax. Rub's auscultatory hallmark is key, guiding anti-inflammatory therapy in chest assessment.
Question 2 of 5
Which of the following is the best test to diagnose pernicious anemia:
Correct Answer: C
Rationale: The Schilling test (C) best diagnoses pernicious anemia measures B12 absorption with/without intrinsic factor (IF), confirming gastric IF loss (e.g., <5% excretion). Marrow (A) shows megaloblasts, nonspecific. Neurologic exam (B) detects neuropathy, late. Smear (D) and indices show macrocytosis (MCV >100 fL), not cause. Schilling's specificity is key in nursing for B12 vs. folate differentiation and lifelong therapy.
Question 3 of 5
Cholelithiasis may be due to one of the following:
Correct Answer: D
Rationale: Cholelithiasis gallstones stems from hemolytic anemia (D), where excess bilirubin from RBC breakdown (e.g., sickle cell, Hb 8 g/dL) forms pigment stones. Malignancy (A) or cirrhosis (C) may obstruct, not form stones. High fat diet (B) risks cholesterol stones, less specific here. CHF causes congestion, not lithiasis. Hemolysis's bilirubin overload is key, guiding nursing for ultrasound and monitoring jaundice in anemia patients.
Question 4 of 5
In chronic lymphocytic leukemia the lymph nodes are characterized by all of the following, except:
Correct Answer: B
Rationale: Chronic lymphocytic leukemia (CLL) lymph nodes show early enlargement (A), discrete (C), diffuse involvement (D), and mobility , but not tender/painful (B) painless growth (e.g., >1 cm) reflects slow B-cell accumulation. Tenderness fits infection or Hodgkin's. CLL's indolent lymphadenopathy is key, guiding nursing for staging and infection watch.
Question 5 of 5
Hemolytic anemia is not usually found in:
Correct Answer: D
Rationale: Hemolytic anemia RBC destruction occurs in G-6-PD (A drug-induced), thalassemia (B ineffective erythropoiesis), spherocytosis (C spleen lysis), HbC (D mild hemolysis) but not iron deficiency , where low iron reduces RBC production (e.g., Hb <10 g/dL), not lysis. Iron's non-hemolytic nature is key, guiding nursing for iron, not hemolysis workup.
