Oxygenation NCLEX Questions Questions
Question 1 of 5
Which of the following ABG results is typical for a client with emphysema?
Correct Answer: C
Rationale: Chronic CO2 retention in emphysema leads to compensated respiratory acidosis: low pH, high PaCO2, and elevated HCO3.
Question 2 of 5
Which changes would be most appropriate for a patient on mechanical ventilation with the following ABG: pH 7.33, PaCO₂ 36 mmHg, PaO₂ 66, HCO⁴‚ƒ 19 mmol/L
Correct Answer: C
Rationale: The ABG shows metabolic acidosis (low HCO⁴‚ƒ) with low PaO₂. Increasing inspiratory pause improves oxygenation by allowing more time for gas exchange, addressing the PaO₂ of 66.
Question 3 of 5
Which medication is a combined Long Acting Beta Agonist (LABA) and a Long-Acting Muscarinic Agent (LAMA)?
Correct Answer: D
Rationale: Anoro Ellipta combines a LABA (vilanterol) and a LAMA (umeclidinium) for COPD management.
