Questions for the Respiratory System Questions
Question 1 of 5
The following conditions predispose to abscess formation in the lung:
Correct Answer: C
Rationale: Pulmonary infarction (C) embolic necrosis predisposes to lung abscess; tissue death fosters anaerobic infection (e.g., Bacteroides). Pneumococcus type III pneumonia (A) consolidates, rarely necrotizes. Sideroderma (B likely scleroderma misprint) affects vessels, not abscesses. Mitral stenosis (D) causes congestion, not infarction. Regional enteritis (E Crohn's) links to GI, not lungs. Infarction's ischemic damage, often post-embolus, is key in abscess pathogenesis, guiding imaging and antibiotics in chest nursing.
Question 2 of 5
Match the following: 678. Prednisone
Correct Answer: D
Rationale: Prednisone, a corticosteroid, causes psychosis, peptic ulcer, osteoporosis glucocorticoid effects on CNS, gastric mucosa, and bone (e.g., 20% bone loss risk). Myelosuppression (A) fits cytotoxics. Protein defects (B) tie to asparaginase. Neuropathy (C) is vincristine. Cystitis (D) is cytoxan. Prednisone's side effects are key in nursing for steroid tapering and GI protection.
Question 3 of 5
Which of the following is true of hemophilia:
Correct Answer: B
Rationale: Hemophilia typically A (factor VIII) features AHG (antihemophilic globulin) deficiency (B), prolonging aPTT (e.g., >50s), not PT (A factor VII, D). Factor V (C) is unrelated. None' dismisses. VIII deficiency causes joint bleeds, key in nursing for factor replacement and bleeding precaution education.
Question 4 of 5
In man the Ebstein-Barr virus is associated with which of the following disease:
Correct Answer: D
Rationale: Epstein-Barr virus (EBV) links to Burkitt's lymphoma (A B-cell malignancy) and infectious mononucleosis (C lymphocytosis, fever), thus D (A & C). Retropharyngeal cancer (B) lacks EBV association HPV or smoking dominate. All' overstates. EBV's oncogenic (Burkitt's) and infectious (mono) roles are key, guiding nursing for serology (e.g., VCA-IgM) and lymphoma staging.
Question 5 of 5
In sickle cell anemia there is a greater incidence of gall stones. What other situation might confuse the diagnosis:
Correct Answer: B
Rationale: Sickle cell anemia's gallstones (pigment stones) overlap with sickle cell crisis (B) both cause abdominal pain, jaundice (e.g., bilirubin >3 mg/dL), mimicking cholecystitis. Icterus (A) is a sign, not diagnosis. Joint pain (C) is articular. Coronary infarction (D) or perforated viscus differ chest, peritonitis. Crisis's vaso-occlusion confuses, key in nursing for imaging and pain differentiation.
