168. In what way are croup and laryngotracheobronchitis significantly similar?
a. Client is afebrile with both.
b. Both are viral in origin.
c. Age range of susceptibility is the same.
d. Speed of onset is identical.
167. Correct answer: b.
Rust-colored sputum, pleuritic pain, cough, and fever are classic signs of bacterial pneumonia. PaO2 is decreased secondary to consolidation in the lung. An expiratory wheeze is characteristic of asthma not pneumonia.
168. Correct answer: b.
Both diseases are viral in origin. With croup, children are afebrile; with laryngotracheobronchitis, children have fever. Croup primarily affects children aged 6 months to 3 years and laryngotracheobronchitis affects children under 5 years of age. Onset of croup is sudden and onset of laryngotracheobronchitis is more gradual.
