Welcome to your Flash. Resp Oxygen therapy

Flashcard# 1 Resp. Oxygen therapy

What is the primary indication for administering oxygen therapy?

Hypoxemia or low arterial oxygen levels.

Flashcard# 2 Resp. Oxygen therapy

Why might a patient with chronic obstructive pulmonary disease (COPD) require supplemental oxygen?

To alleviate chronic hypoxemia and prevent complications like pulmonary hypertension.

Flashcard# 3 Resp. Oxygen therapy

What potential complication can arise from prolonged high-dose oxygen therapy in preterm infants?

Retinopathy of prematurity.

Flashcard# 4 Resp. Oxygen therapy

What complication can high concentrations of oxygen cause in patients with COPD?

Hypercapnia (increased carbon dioxide levels in the blood) due to suppression of their hypoxic drive.

Flashcard# 5 Resp. Oxygen therapy

How can excessive oxygen therapy affect the respiratory system?

It can lead to oxygen toxicity, resulting in inflammation and scarring of lung tissues.

Flashcard# 6 Resp. Oxygen therapy

Why should oxygen therapy be administered cautiously in patients with COPD?

Over-oxygenation can decrease their respiratory drive, potentially leading to respiratory failure.

Flashcard# 7 Resp. Oxygen therapy

Why is it important to monitor oxygen saturation (SpO2) levels continuously during oxygen therapy?

To ensure adequate oxygenation without causing hyperoxia.

Flashcard# 8 Resp. Oxygen therapy

What's a potential fire hazard when using oxygen therapy?

Oxygen supports combustion; thus, open flames and smoking should be strictly avoided during its use.

Flashcard# 9 Resp. Oxygen therapy

Before initiating oxygen therapy, what should the nurse ensure?

That there's a valid physician's order specifying the oxygen flow rate and method of delivery.

10.

Flashcard# 10 Resp. Oxygen therapy

Why should the nurse regularly monitor the patient's nasal passages and ears when using a nasal cannula?

To check for signs of irritation or pressure ulcers.

11.

Flashcard# 11 Resp. Oxygen therapy

What action should a nurse take if a patient complains of dry or irritated nasal passages during oxygen therapy?

Consider humidifying the oxygen or applying water-soluble lubricant to the nostrils.

12.

Flashcard# 12 Resp. Oxygen therapy

Why should the nurse frequently assess a patient's respiratory rate, rhythm, and depth during oxygen therapy?

To detect changes in respiratory status and ensure effective oxygenation.

13.

Flashcard# 13 Resp. Oxygen therapy

When using an oxygen mask, what is essential for the nurse to ensure regarding the mask's fit?

That it fits securely to prevent room air from being mixed with the oxygen.

14.

Flashcard# 14 Resp. Oxygen therapy

How often should a nurse change and clean the oxygen delivery system to ensure patient safety?

As per hospital policy, typically every 24 hours, or sooner if it becomes soiled.

15.

Flashcard# 15 Resp. Oxygen therapy

What is a critical nursing consideration when transitioning a patient from a high oxygen concentration to room air?

Gradually titrate down the oxygen concentration to prevent rapid changes in oxygen levels, which can be harmful.

16.

Flashcard# 16 Resp. Oxygen therapy

Why is patient education about the dangers of smoking near oxygen crucial?

Because oxygen supports combustion, smoking near an oxygen source can cause fires.

17.

Flashcard# 17 Resp. Oxygen therapy

What intervention can be used for a patient experiencing ear discomfort with continuous oxygen delivery?

Periodically alternate the positioning of the tubing, ensuring it's not causing pressure on the ears.

18.

Flashcard# 18 Resp. Oxygen therapy

What action should a nurse take if the oxygen equipment malfunctions?

Immediately ensure the patient's safety, switch to an alternative oxygen source if available, and notify the appropriate department to fix or replace the equipment.

19.

Flashcard# 19 Resp. Oxygen therapy

Why should a nurse monitor a patient's color, level of consciousness, and other clinical signs during oxygen therapy?

These can provide additional information about the patient's oxygenation status and overall well-being.

20.

Flashcard# 20 Resp. Oxygen therapy

In cases of suspected carbon dioxide retention in COPD patients receiving oxygen therapy, what should the nurse be prepared to do?

Reduce the oxygen flow rate and immediately notify the healthcare provider for further assessment and management.
