Respiratory System Flashcards
The nose, mouth, pharynx, larynx and trachea are part of the _____ respiratory system
Upper
Function of the upper respiratory system
Warm, humidify, and filter air we breathe
The bronchi, bronchioles, alveolar ducts, and alveoli are part of the _____ respiratory system
Lower
Function of the lower respiratory system
Gas exchange
The functional units for gas exchange
Alveoli
The flow of air in and out of the alveoli
Ventilation
The exchange of oxygen and carbon dioxide between the alveoli and red blood cells in the bloodstream
Diffusion
The exchange of oxygen and carbon dioxide between the red blood cells and the body’s tissues
Perfusion
Structure that surrounds and cushions the lungs
Pleura
Normal pH
7.35-7.45
Normal PaCO2
35-45
Normal HCO3
22-26
Normal PaO2
80-100
Normal SaO2
95-100%
Insertion of a tube into a patient’s airway that allows for visualization of the airway and collection of specimen
Bronchoscopy
Pre-procedure nursing care for bronchoscopy
NPO (ranges between 4-8 hours)
Post-procedure nursing care for bronchoscopy
Assess for return of gag reflex before providing anything to eat or drink
T or F: the nurse should educate the patient that a sore, dry throat and blood tinged mucus is expected following a bronchoscopy
True
The nurse should monitor the patient for complications such as _________ following a bronchoscopy
Pneumothorax
The insertion of a needle into the patient’s posterior chest to remove fluid or air from the pleural space
Thoracentesis
Pre-procedure nursing care for thoracentesis
Have patient sit upright with arms supported on bedside table or pillows
Nursing care during thoracentesis
Advise patient to remain perfectly still (do NOT talk, move, or cough)
Post-thoracentesis, the nurse should monitor the patient for complications such as
Pneumothorax, bleeding, hypotension
T or F: an SpO2 of 90% is an expected finding in a patient with COPD
True
Nasal cannula O2 delivery
1-6 L/min
A patient receiving O2 over 4 L/min via nasal cannula may experience drying of the nares. What can the nurse provide to prevent this?
Water-based lubricant; humidified oxygen
Simple face mask O2 delivery
6-10 L/min
The nurse should inflate the bag attached to a partial rebreather and a non-rebreather mask to about ___ full. Flow rate should be adjusted to keep the bag inflated to this fullness to prevent the patient from suffocating.
2/3
Non-rebreather flow rate
10-15 L/min
Partial rebreather flow rate
10-12 L/min
Which oxygen delivery device provides high humidifcation and the most precise oxygen delivery without intubation?
Venturi mask
Venturi device flow rate
Depends on mask attached to it; varies between 4-12 L/min
Face tents are ideal for patients with facial trauma. This device provides high humidification and delivers over ___ L/min
15
Insufficient O2 in the arterial blood (<80 mmHg)
Hypoxemia
Insufficient tissue oxygenation
Hypoxia
Restlessness, irritability, abnormal breathing (use of accessory muscles, nasal flaring, adventitious lung sounds), tachycardia, hypertension and pallor are _____ signs of hypoxia
Early
Decreased LOC, increases lactic acid levels (lactic acidosis), dysrhythmias, bradypnea, bradycardia, hypotension, and cyanosis are _____ signs of hypoxia
Late
S/S of oxygen toxicity
Non-productive cough, nasal congestions, substernal pain, headache, N/V, fatigue, sore throat
Sleep apnea is defined as breathing disruption that occurs during sleep lasting at least ___ seconds and occurs ___ or more times per hour
10; 5
Sleep apnea risk factors
Obesity, large tonsils, neuromuscular/endocrine disorders
S/S of sleep apnea
Persistent daytime sleepiness or irritability
Chronic inflammatory disorder of the airway that is intermittent and reversible
Asthma
S/S of asthma
Dyspnea, wheezing, chest tightness, coughing, tachypnea, use of accessory muscle, prolonged expiration, barrel chest (w/ severe and prolonged asthma)
The nurse should educate the patient to keep tabs on their asthma using a _________ which alerts the patient to airway narrowing before they even experience symptoms
Peak flow meter
How should the nurse instruct the patient to use their peak flow meter for asthma?
Use three times and record the highest number of the three attempts
For exercise-induced asthma, the patient should take their bronchodilator ___ min before exercise
30
