01
Front

What does oxygenation describe?

Back

Oxygenation is the transfer of oxygen into the blood.

02
Front

What ABG pattern indicates respiratory acidosis with little compensation?

Back

Low pH with elevated PaCO₂ indicates respiratory acidosis. Near-normal HCO₃⁻ suggests little or no substantial metabolic compensation.

03
Front

Which findings can signal worsening respiratory compromise?

Back

Restlessness or confusion, rapid breathing, accessory-muscle use, and falling oxygen saturation can signal worsening respiratory compromise.

04
Front

What is the priority for an unresponsive patient with gurgling respirations?

Back

Assess and open the airway, summon emergency help, and prepare suction and ventilation support.

05
Front

What should be done when noninvasive ventilation is failing and the patient cannot protect the airway?

Back

Escalate urgently and prepare for advanced airway management as directed by the emergency team.

06
Front

What is the first response to a ventilator high-pressure alarm?

Back

Assess the patient first, then check for causes such as secretions, a kinked tube, coughing, or biting.

07
Front

What should a comprehensive respiratory assessment include?

Back

Assess respiratory rate and pattern, work of breathing, mental status, speech, skin color, breath sounds, oxygen saturation, and trends.

08
Front

What does ventilation describe?

Back

Ventilation is the movement of air in and out of the lungs and supports carbon dioxide removal.

09
Front

What does pulse oximetry not measure directly?

Back

Pulse oximetry estimates oxygen saturation; it does not directly measure PaCO₂ or ventilation.

10
Front

What does a low PaO₂ indicate?

Back

A low PaO₂ indicates hypoxemia. PaO₂ alone does not establish carbon dioxide retention or identify its cause.

11
Front

Why is new stridor with difficulty speaking an emergency?

Back

Stridor with difficulty speaking can signal critical upper-airway obstruction and requires immediate assessment and emergency escalation.

12
Front

What is a systematic sequence for interpreting an ABG?

Back

Assess pH, determine whether PaCO₂ or HCO₃⁻ explains the pH change, then consider compensation and oxygenation.
