Q

What are some home care considerations for suctioning

A

to clean– suction boiling water then suction air until the tube is dry

25
Q

What are Non-invasive positive pressure ventilation used the most for

A

obstructive sleep apnea (OSA)

26
Q

What are some lifespan considerations for children for suctioning

A

use a catheter

27
Q

What are some considerations with suctioning a trach tube

A

only suction on the way out, limit to 5 to 10 seconds

use sterile technique

28
Q

What are oro and nasopharyngeal airways used for

A

keeping the upper airways open in patient who might have secretions or a tongue that causes onbstruction like comatose, sedated, or patients with altered LOC

29
Q

What amount of oxygen can a cannula deliver

A

25-45% at flow rates of 2-6L/min

30
Q

What needs to be added to a dry oxygen supply

A

a humidifier essentially for liter flows over 4L/min

31
Q

What conditions require Non-invasive positive pressure ventilation

A

chronic/acute respiratory failure
pulmonary edema
COPD
obstructive sleep apnea

32
Q

What are some oxygen therapy safety precautions

A

always smoke away from the oxygen supply
place cautionary no smoking signs near the oxygen supply
make sure electrical equipment is working to prevent sparks
avoid materials that generate static electricity
Avoid using volitile materials near the oxygen supply
Teach location of fire extinguishers

33
Q

What are some safety precautions for cylinder oxygen

A

store away from heat and high traffic

secure to something

34
Q

Whats the difference between CPAP and BiPap

A

BiPap has two pressure settings while CPAP doesnt

35
Q

Why is humidification for reservior nasal cannulas not required

A

because the moisture from the patient exhaling is capture and then redelivered on the next inspiration

36
Q

What are some nursing interventions for clients with endotracheal tubes

A

Assess clients respiratory status q2h
maintain a cuff pressure of 20-25 mmHg
provide a picture board or note pad for communication
provide oral and nasal care every 2-4hours
unless contraindicated, elevate bed to 30-45 degrees

37
Q

Is humidification required for reservior nasal cannulas

A

no

38
Q

What are the limitations of masks

A

finding the right size

poor tolerance of them by the client

39
Q

What are some lifespan considerations for infants for suctioning

A

use a bulb syringe

40
Q

When can the nurse administer oxygen tharapy

A

with an order from the PCP

during emergencies without a PCP order

41
Q

What is a special consideration for venturi masks

A

they have multiple sizes for tubing which are typically color coded for a specific O2 concentration so make sure you have the right tube

42
Q

How do you determine the correct size suction catheter for ETT (endotracheal tubes) or tracheostomys

A

double the millimeter size of the artificial airway being used. for example if a 8mm tracheostomy is used the max size catheter that should be used is size 16

43
Q

What kind of patients usually get face tents

A

anesthesia patient s

44
Q

How does CPAP and BiPap work

A

they keep the alveoli and airways open

45
Q

Because oropharyngeal airways stimulate the gag reflex they are only used on who

A

patients with altered LOC like anesthesia, head injuries, and overdoses

46
Q

What are some lifespan considerations for older adults for suctioning

A

watch for signs of hypoxemia, stop and hyperoxygenate if you see signs

47
Q

What does some nursing care of trachs involve

A

cleaning and suctioning

48
Q

What are the two types of tracheostomy’s

A

normal

cuffed

49
Q

What is the advantage of cuffed trachs

A

their Airtight seal prevents aspiration and air leakage

50
Q

Are humidifiers required for normal cannula

A

yes

51
Q

What are the two types of reservior nasal cannulas

A

pendant style

mustashe style

52
Q

What are the four most common artificial airways clients can have

A

oropharyngeal
nasopharyngeal
endotracheal
tracheostomy

53
Q

What are the limitations of cannula

A

they cant deliver high concentrations of oxygen

they can dryout mucous membranes

54
Q

What does FiO2 mean

A

fraction of inspired O2

55
Q

How much oxygen concentration can a simple face mask deliver

A

40-60% at liter flows 5-8L/min

56
Q

What does BiPap stand for

A

bilevel positive air pressure

57
Q

What are the complications associated with suctioning endotracheal or tracheostomy tubes

A

hypoxemia
infection
cardiac dysrythmia

58
Q

What fraction of O2 can a reservior nasal cannula deliver

A

0.5 or greater

59
Q

What O2 concentration can face tents deliver

A

30-50% at liter flows of 4-8L/min

60
Q

What type of schedule is suctioning usually on

A

as needed based on respiratory distress or inability to expectorate
