Practice Question
A nurse is reviewing the ABG values of a client who has chronic bronchitis and reports dyspnea with minimal exertion. Which of the following acid-base imbalances should the nurse suspect?
Answer Choices:
Correct Answer:
Respiratory acidosis
Rationale:
🔷 Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) characterized by airflow obstruction and CO₂ retention.
🔷 Hypoventilation leads to CO₂ accumulation (hypercapnia), increasing carbonic acid levels and causing respiratory acidosis.
🔷 Arterial blood gas (ABG) values typically show ↓ pH (<7.35) and ↑ PaCO₂ (>45 mm Hg).
🔷 Dyspnea with minimal exertion indicates worsening gas exchange and CO₂ retention.
🔷 Chronic cases may also show renal compensation with increased HCO₃⁻, but the primary imbalance remains respiratory acidosis.
