7 Integrated Respiratory Care Practice Online Quiz Questions

True or false: Supplemental oxygen alone corrects inadequate ventilation.

Which arterial blood gas variable reflects ventilation?

A patient with COPD is drowsy and has an ABG of $\mathrm{pH}=7.28$, $\mathrm{PaCO_2}=68\,\mathrm{mm\ Hg}$, and $\mathrm{HCO_3^-}=31\,\mathrm{mEq/L}$. Which interpretation best fits these results?

True or false: If a patient with COPD becomes drowsy while struggling to breathe, escalation should wait until another ABG is obtained.

For adults with ARDS, the recommended plateau pressure is below what numerical threshold?

A patient with pneumonia has $\mathrm{pH}=7.49$, $\mathrm{PaCO_2}=30\,\mathrm{mm\ Hg}$, $\mathrm{PaO_2}=52\,\mathrm{mm\ Hg}$, and is receiving $\mathrm{FiO_2}=0.60$. Which interpretation is best?

A ventilated patient suddenly desaturates and becomes hypotensive as a high-pressure alarm sounds. What should the nurse prioritize first?

Which findings make noninvasive ventilation unsafe or inadequate for a patient with respiratory distress? Select all that apply.

A patient with COPD is increasingly drowsy, tachypneic, and using accessory muscles. Describe the immediate nursing priorities and explain when NIV may be unsafe or inadequate.

A ventilated patient suddenly becomes hypotensive and desaturates, with markedly decreased breath sounds on the left. Which immediately life-threatening cause must be considered?

A mechanically ventilated patient triggers a high-pressure alarm. The nurse should assess the patient before simply silencing the alarm or changing ventilator settings.

A patient with COPD becomes more drowsy while receiving supplemental oxygen. SpO₂ improves, but PaCO₂ remains elevated. Which interpretation best separates oxygenation from ventilation?

A patient with COPD and CO₂ retention needs supplemental oxygen. Which SpO₂ target is often used, while still individualizing care to the patient and prescribed plan?

A patient with pneumonia has pH $7.49$, PaCO₂ $30$ mm Hg, and HCO₃⁻ $22$ mEq/L. What is the primary acid–base disorder?

A patient with pneumonia is tiring, breathing rapidly, and has SpO₂ $88\%$ despite FiO₂ $0.60$. PaCO₂ is low. Which conclusion best supports urgent escalation?

A patient with COPD has pH $7.28$, PaCO₂ $68$ mm Hg, and HCO₃⁻ $31$ mEq/L. What does the elevated bicarbonate most reasonably suggest?

For adults with ARDS, below what plateau-pressure threshold should ventilation be maintained? Enter the value in cm H₂O.

An adult with ARDS has a predicted body weight of $60$ kg. The team is using a lung-protective tidal-volume range of $4$–$8$ mL/kg predicted body weight. Which proposed tidal volumes are within that range? Select all that apply.
