The nurse is caring for a child with an acute exacerbation of asthma. For which reason should the nurse consider this child at risk for developing respiratory acidosis?

Bronchoconstriction decreases PaCO2, decreasing pH.
Air trapping increases PaCO2 levels, decreasing pH.

Before a meal
The nurse is caring for a patient with chronic obstructive pulmonary disease (COPD). The patient's arterial blood gas (ABG) results reveal compensated chronic respiratory acidosis. The nurse should understand that which physiological mechanism is causing the compensated chronic respiratory acidosis in this patient? ANSWER - Carbon dioxide levels decrease in response to increased pH. - Carbon dioxide levels increase in response to decreased bicarbonate levels. - Bicarbonate levels increase in response to increased pH. - Bicarbonate levels increase in response to increased carbon dioxide levels.
Bicarbonate levels increase in response to increased carbon dioxide levels.
