Answer and Explanation

The Correct Answer is C

Correct Answer is B

Explanation

A. Accessory muscle use is a response to respiratory distress, not the underlying cause of asthma symptoms.

B. Asthma causes inflammation and swelling of the bronchial lining, which narrows the airways and makes it difficult to exhale air from the lungs, leading to prolonged expiration and wheezing.

C. Destruction of elastic recoil is associated with chronic lung conditions like emphysema, not asthma.

D. Stiff alveoli and fluid-filled lungs are more characteristic of restrictive lung diseases or pulmonary edema, not asthma.

A. expiratory wheeze; PCO₂ 36 B. respiratory rate of 42; SO₂ 79% C. respiratory rate of 24; pH 7.46 D. barking cough; PO₂ 90

Correct Answer is B

Explanation

A. An expiratory wheeze with a PCO₂ of 36 (within normal range) does not typically indicate respiratory failure.

B. A respiratory rate of 42 and a low oxygen saturation (SO₂) of 79% indicate hypoxemia and respiratory distress, which are hallmarks of respiratory failure.

C. A respiratory rate of 24 with a pH of 7.46 suggests mild hyperventilation or anxiety rather than respiratory failure.

D. A barking cough and a PO₂ of 90 are not indicative of respiratory failure; PO₂ of 90 is within normal limits.
