2.2 Oxygen Refresher

The nurse walks into a patient's room early morning to obtain vitals. The patient is laying in a supine position. Upon assessment, the nurse obtains a pulse oximetry reading of 89%. What should the nurse do first?

• Notify the PCP

• Encourage deep breathing

• Apply 2L of oxygen via NC

• Raise the head of the bed to high fowlers

A nurse is performing a lung assessment. Upon auscultation, she hears a continuous high pitch musical sound, indicating possible obstruction of the airway. How should the nurse document her finding?

• Crackles

• Wheezing

• Ronchi

• Normal

Which clinical manifestations are most reflective of a patient experiencing early s/sx of hypoxia? Select all that apply.

• Confusion

• Restlessness

• Cool, clammy skin

• Tachypnea

True or false? To ensure the lowest level necessary to maintain SPO2, oxygen levels should be titrated up.

• True

• False

A patient has been diagnosed with severe iron deficiency anemia. During physical assessment for which of the following symptoms would the nurse assess to determine the patient's oxygen status?

• Increased breathlessness but increased activity tolerance

• Decreased breathlessness and decreased activity

• Increased activity tolerance and decreased breathlessness

• Decreased activity tolerance and increased breathlessness

Which nursing intervention is appropriate for preventing atelectasis in the postoperative patient?

• Thoracentesis

• Suctioning

• Incentive Spirometer

• Chest percussion

The nurse needs to apply oxygen to a patient who needs controlled-oxygen therapy. Which of the following oxygen delivery systems should the nurse use to deliver oxygen to the patient?

• Nasal Cannula

• Simple face mask

• Venturi mask

• Nonrebreather mask

For a patient with chronic obstructive pulmonary disease, which nursing intervention would help maintain a patent airway?

• Enforcing absolute bed rest

• Restricting fluid intake to 1,000 ml/day

• Teaching the client how to perform controlled coughing and deep breathing exercises

• Administering prescribed sedatives regularly and in large amounts

The primary role of the alveoli is to:

• Vasodilate the airways

• Carry out gas exchange

• Help the lungs expand

• Inhibit gas exchange

It's important to educate patients to perform hourly breathing exercises to prevent:

• Atelectasis

• Cyanosis

• COPD

• Dehydration
