NUR102: Ch. 41 Oxygenation

A nurse explains the function of the alveoli to a patient with respiratory problems. Which information about the alveoli’s function will the nurse share with the patient?

• Carries out gas exchange.

• Regulates tidal volume.

• Produces hemoglobin.

• Stores oxygen.

A nurse is caring for a patient who was in a motor vehicle accident that resulted in cervical trauma to C4. Which assessment is the priority?

• Pulse

• Respirations

• Temperature

• Blood pressure

While performing an assessment, the nurse hears crackles in the patient’s lung fields. The nurse also learns that the patient is sleeping on three pillows to help with the difficulty breathing during the night. Which condition will the nurse most likely observe written in the patient’s medical record?

• Atrial fibrillation

• Myocardial ischemia

• Left-sided heart failure

• Right-sided heart failure

A nurse teaches a patient about atelectasis. Which statement by the patient indicates an understanding of atelectasis?

• “Atelectasis affects only those with chronic conditions such as emphysema.”

• “It is important to do breathing exercises every hour to prevent atelectasis.”

• “If I develop atelectasis, I will need a chest tube to drain excess fluid.”

• “Hyperventilation will open up my alveoli, preventing atelectasis.”

The nurse is caring for a patient with respiratory problems. Which assessment finding indicates a late sign of hypoxia?

• Elevated blood pressure

• Increased pulse rate

• Restlessness

• Cyanosis

A nurse is caring for a patient diagnosed with chronic obstructive pulmonary disease (COPD) who is receiving 2 L/min of oxygen. Which oxygen delivery device is most appropriate for the nurse to administer the oxygen?

• Nasal cannula

• Simple face mask

• Non-rebreather mask

• Partial non-rebreather mask

The nurse determines that an older-adult patient is at risk for infection due to decreased immunity. Which plan of care best addresses the prevention of infection for the patient?

• Inform the patient of the importance of finishing the entire dose of antibiotics.

• Encourage the patient to stay up-to-date on all vaccinations.

• Schedule patient to get annual tuberculosis skin testing.

• Create an exercise routine to run 45 minutes every day.

The nurse is creating a plan of care for an obese patient who is experiencing fatigue related to ineffective breathing. Which intervention best addresses a short-term goal the patient could achieve?

• Sleeping on two to three pillows at night

• Sensibly reducing daily calorie intake

• Running 30 minutes every morning

• Stopping smoking immediately

Which nursing intervention is most effective in preventing hospital-acquired pneumonia in an older-adult patient?

• Discontinue the humidification delivery device to keep excess fluid from lungs.

• Monitor oxygen saturation, and frequently auscultate lung bases.

• Assist the patient to cough, turn, and deep breathe every 2 hours.

• Decrease fluid intake to 300 mL a shift.

A nurse is caring for a patient being treated for sleep apnea. Which types of ventilator support should the nurse be prepared to administer for this patient? (Select all that apply.)

• Assist-control (AC)

• Pressure support ventilation (PSV)

• Bilevel positive airway pressure (BiPAP)

• Continuous positive airway pressure (CPAP)

• Synchronized intermittent mandatory ventilation (SIMV)
