Exam 3: Respiratory Flashcards
(46 cards)
What is Fi02?
Percentage of oxygen in the air that is available to the client
What is the first sign of hypoxia?
neurological deficits like altered mental status, restlessness, confusion, or anxiety
What are the signs and symptoms of hypoxia?
Restlessness
Decreased LOC
Dizziness
Behavioral changes
Fatigue
Agitation
Tachycardia
Cyanosis – Not a reliable indicator
Why is cyanosis not a reliable indicator of hypoxia?
can be difficult in darker skinned clients
How do we assess for cyanosis is darker skinned clients?
Central Cyanosis in the tongue and conjunctiva. The bluish appearance of either is a more reliable indicator of hypoxia.
What are signs that your client has an airway obstruction?
Not talking, stridor, unconscious (tongue)
What are some common airway obstructions?
Tongue
FBO
Vomit, secretions, mucus
Toys, nails, cereal
How is a foreign body removed from the airway?
CPR, Heimlich, backblows
What are interventions to address airway issues?
suctioning, pulmonary hygiene, artificial airway, intubation, trach
What are indications for suctioning?
when patients are unable to clear respiratory secretions from the airways by coughing or other less invasive procedures
What is the purpose of pulmonary hygiene/toilet?
the action of mobilizing respiratory secretions for removal
What is the benefit of hydration in pulmonary hygiene?
Adequate hydration helps to maintain the ability to clear secretions by liquifying the sputum making it thin and easily removable with minimal coughing
How would you hydrate a client who is NPO?
IV hydration
What are the dangers of retained mucus?
Increases WOB
Traps bacteria allowing them to colonize
Leads to excessive coughing
Can lead to formation of mucus plugs which hinder gas exchange
What is the purpose of incentive spirometry?
encourages voluntary deep breathing by providing visual feedback to patients about inspiratory volume
prevent atelectasis
What is atelectasis?
condition that prevents the alveoli from expanding causeing portions of the lungs to collapse and is a complication when recovering from surgery
What are the benefits of ambulation in pulmonary hygiene?
increase the general strength of the client as well as increase lung expansion. This expansion shifts mucus to the larger airways and is easier to expectorate.
Which clients are candidates for early ambulation?
Critically ill clients can be placed into early ambulation programs with assistance from respiratory therapy and physical therapy
When is an artificial airway indicated?
Anytime you use BVM
decreased level of consciousness or airway obstruction
What are indications and contraindications for an oropharyngeal and nasopharyngeal airway?
OPA
Displaces tongue
Unconscious - cannot have a gag reflex
NPA
Patient can be conscious
Cannot suspect a facial fracture
What is the nurse’s role in endotracheal intubation?
Call provider to update on status and potential need for further respiratory intervention
Inform and educate patient and family – this is a major event in the care of the patient and family should be notified
Confirm that the patient and/or family wants further intervention
Gather supplies for intubation procedure
Notify respiratory therapist for mechanical ventilator to be brought to room
What is the most common complication of a tracheostomy tube?
partial or total airway obstruction caused by buildup of respiratory secretions
What are safety precautions that we take with tracheostomy clients?
Always know the size of your clients trach –
Always have a new trach usually a size below your patients current trach at the bedside for emergencies – if the trach comes out you can place the smaller trach in the stoma to provide ventilation an oxygenation
How is oxygen administered to a client with a tracheostomy?
Oxygen delivery for trach is via a trach collar which is a specific device designed to fit over the trach
Oxygen delivery is through a humidification cylinder and communicated and regulated as FiO2 % as opposed to Liters of oxygen
Example: 40% TC (trach collar) as opposed to 6 L NC (nasal cannula)
