Set 11 Flashcards
The movement of air in and out of the alveoli/lungs
Ventilation
The exchange of gasses (CO2 and O2) from the alveoli to the capillaries (intravascular space)
Diffusion
The exchange of gasses (CO2 and O2) between the blood and the tissues
Perfusion
Low oxygen in the blood, specifically arterial blood
Hypoxemia
What is needed for the diagnosis of hypoxemia?
ABG
Decreased oxygen in the tissues
Hypoxia
Early signs of decreased oxygenation
Restlessness, irritability, anxiety
Late signs of decreased oxygenation
Change of LOC, cyanosis
Techniques to improve oxygenation
- deep breathing
- coughing
- positioning (High fowlers for conscious patient)
- incentive spirometry
How often should patients use incentive spirometer?
10 times/hr every hour that they’re awake
What kind of lubricant should be used on a patient with a nasal cannula to prevent drying?
Water-based lubricant
A nonrebreather bag needs to be _________ inflated prior to applying while a partial rebreather bag needs to be ________ full.
Fully; 2/3
The _________ device allows a precise fiO2 (up to 40% w/o intubation) to be delivered to the patient
Venturi
Postural drainage, percussion, and vibration to help break up thick secretions and get them out of the patient
Chest physiotherapy
When should chest physiotherapy be scheduled?
Before meals or 1-2 hours after meals to prevent N/V
What should the nurse do prior to suctioning a patient?
Hyperoxygenate w/ 100% O2
When should the nurse apply suction?
Apply intermittent suction upon withdraw of the catheter. NEVER apply suction while inserting the catheter
The nurse should limit suctioning to ___ to ___ seconds per pass and _________ TOTAL passes
10-15; three
Chest tube drainage to be reported to the provider
More than 100 mL/hr
Continuous bubbling in the water seal chamber of chest tube indicates
A leak
T or F: continuous bubbling is expected in the suction control chamber of chest tube
True
Nursing interventions in the case of continuous bubbling in the water seal chamber of chest tube OR if chest tube were to become disconnected from the collection device
Place the end of tube into sterile water/saline, call the provider
Tracheostomy care
clean from the stoma outward with STERILE technique
Home oxygen safety
- NO smoking; place signs inside and outside of house
- keep oxygen tank upright and housed securely
- used water-based lubricants
- wear cotton clothes
- repair/replace frayed electrical cords
How often should vital signs be assessed for a patient in PACU?
Every 5-15 minutes
