7 Integrated Impaired Oxygenation Practice Questions Online Quiz Questions

Four patients need assessment. Which patient should the nurse assess first?

The day after surgery, a patient develops sudden shortness of breath and sharp pain with inspiration. The patient is tachycardic and hypoxemic, has no fever, and has relatively clear breath sounds. Which condition should the nurse urgently consider?

True or false: A hypoxemic patient with COPD should have oxygen withheld because oxygen can worsen COPD.

A patient’s arterial blood gas shows pH 7.29 and PaCO₂ 66 mmHg. What acid-base disturbance does this pattern indicate?

A patient with pneumonia becomes confused, breathes 32 times per minute, and has an oxygen saturation of 85%. Select all appropriate immediate actions.

A patient with COPD has increased breathlessness and an oxygen saturation of 84%. Which initial approach to oxygen is most appropriate?

True or false: When assessing impaired oxygenation, the nurse should consider work of breathing, mental status, trends, and response to interventions as well as the pulse-oximeter reading.

For many acutely ill patients with COPD or risk of hypercapnic respiratory failure, the controlled oxygen target while blood-gas results are pending is 88–92%, unless an individualized target applies. What is the lower endpoint? Enter just the number; the fixed unit is shown.

After allergen exposure, a patient has rapidly worsening wheeze and chest tightness, uses accessory muscles, and can speak only a few words at a time. Select all appropriate interpretations or responses.

A patient with COPD is increasingly difficult to arouse, with low oxygen and elevated carbon dioxide on arterial blood gas testing. Which principle should guide the nurse’s response?

A patient has gradually worsening cough, fever, purulent sputum, and focal crackles. Which condition is most consistent with this pattern?

A patient with COPD has an acute increase in breathlessness and an oxygen saturation of 84%. What is the best initial approach to oxygen?

For an acutely ill adult with COPD who is at risk of hypercapnic respiratory failure and has no individualized oxygen target, what is the upper limit of the commonly recommended oxygen saturation target range while blood-gas results are pending?

A patient with severe asthma becomes drowsy and has a very faint or absent wheeze. What is the most appropriate interpretation?

True or false: A pulse-oximeter reading alone can rule out elevated carbon dioxide in a patient with worsening respiratory symptoms.

A patient's arterial blood gas shows a pH of 7.29 and an elevated PaCO₂ of 66 mmHg. What acid-base disturbance does this pattern indicate?

A patient with pneumonia is increasingly confused, breathing 32 times per minute, and has an oxygen saturation of 85%. Which action takes priority?

A patient with COPD becomes progressively less alert during acute care, and the team is concerned that the patient cannot use a noninvasive mask safely. What should the nurse urgently communicate, and what type of respiratory support should the team assess for? Explain why mask ventilation should not be assumed suitable.
