Q

Hypoxia & Hypercapnia, Intervention =

Oxygen therapy can be started without a provider’s order in emergency situations.

Other Interventions:
Elevate HOB + Tripod Positioning + Breathing & Coughing Techniques + O2 Therapy & Equipment + Respiratory Meds + Suctioning + Pain Relief + Chest Physiotherapy + Flutter Valve + Plan Rest Periods + Assess Anxiety Level + Assess for Sleep Apnea + Assess if the Hypoxia or Hypercapnia is an adverse effect from a medication (like Opioids) + Attempt to treat the cause of the Dyspnea (CPAP or BIPAP may be needed)

40
Q

A

Pursed-Lip Breathing, Incentive Spirometer, Cough & Deep Breathing Exercises, Huff Coughing, Vibratory Positive Expiratory Pressure (PEP) Therapy

41
Q

Huff Coughing is a technique that helps-

A

Remove mucous from lungs

42
Q

What is it called when you begin breathing with a slightly active expiration against an expiratory resistance?

A

PEP Therapy

43
Q

Helps people to take slow, deep breaths =

A

Incentive Spirometer

44
Q

For an incentive spirometer, are you supposed to inhale into the device, exhale into the device, or both?

A

You are supposed to inhale into the device

45
Q

What are the steps for the Huff Coughing Technique?

A

Sit up straight with chin tilted slightly up and mouth open.
Take a slow deep breath to fill lungs about three quarters full.
Hold breath for two or three seconds.
Exhale forcefully, but slowly, in a continuous exhalation to move mucus from the smaller to the larger airways.
Repeat this maneuver two more times and then follow with one strong cough to clear mucus from the larger airways.
Do a cycle of four to five huff coughs as part of your airway clearance.

46
Q

After each round of 20 exhales using the PEP, you should-

When should you stop using the PEP?

A

Give 3 deep coughs

Whenever you feel light-headed

47
Q

What is the difference between ABG’s and Pulse Oximetry?

A

ABG’s are an invasive and direct method that can give you your pO2 and SaO2 values.
These can either be done by an Arterial Puncture (Intermittent Analysis with Many Sticks)
Or via a Arterial Catheter (Intermittent Analysis with No Sticks)

Oximetry is a non-invasive, indirect, and continuous method.
Measures SpO2 with a Pulse Oximeter.
Can probe the finger, toe, ear, or bridge of the nose.

48
Q

What are the pro’s and con’s of Oximetry?

A

Useful in decreased LOC. Part of routine Vital Signs.

Low accuracy, SpO2 is less than 70% with motion, thick nails, or anemia.

Useful in the ICU or in a Pre-Op situation where the pt is sedated

49
Q

When in doubt about your oximetry levels, what should you do?

A

Verify with an ABG

50
Q

If a patient is unconscious or sedated, can this mask hypoxia?

A

Yes, so Oximetry can be helpful in finding out if a patient has hypoxia

51
Q

Oximetry can be used to adjust-

A

O2 Flow Rates

52
Q

What maintains the rate, rhythm, and depth of respirations?

A

The Respiratory Center

53
Q

Chemoreceptors react to changes in-

A

Hydrogen, Oxygen, and Carbon Dioxide

54
Q

In a healthy person, what is the strongest stimulus to increase respiratory rate and depth?

A

An increase in pCO2

55
Q

COPD client adapts to chronic, high levels of -

It is because of this that COPD pt’s are insensitive to high-

A

pCO2

pCO2 Levels

56
Q

Does a low level of O2 stimulate respiration in some COPD clients?

A

Yes

57
Q

High levels of O2 may do what to a person’s stimulus to breathe?

A

Reduce It

58
Q

Low flow O2 = How Many Liters?

This amount is not always enough for many people with-

A

1-3 L

COPD

59
Q

The patient diagnosed with COPD has been discharged to home.
Which action indicates that the patient understands the plan of care?
A.) Promises to do pursed-lip breathing.
B.) States actions to reduce pain.
C.) Uses O2 via nasal cannula at 8L/min.
D.) Agrees to call the provider if dyspnea on exertion increases.

A

D is correct

Pain is not a symptom with chronic lung problems, Pleurisy is though.
It is not A because promises from the client are not measurable.
Patient’s with COPD should use low flow oxygen, not an 8L/min nasal cannula.

60
Q

An inflammation of the pleura causes the membranes to rub and grate against each other =

A

Pleurisy

61
Q

Low flow rate oxygen is not always enough for many people with COPD.
What should you assess to ensure that you are making the right choice when giving a patient low flow rate oxygen?

A

Tiltrate O2 should be based on SpO2, ABG’s, and their LOC

62
Q

What are two things that you must ask your patient?

A

What their priorities are, often times their priorities do not line up with nursing priorities.

What their expectations are from their visit.

63
Q

What are some respiratory related health history things to figure out about if your patient has?

A

Health Risks
Pain
Fatigue
Dyspnea
Cough
Environmental & Occupational Exposures
Smoking
Respiratory Infections
Allergies
Medications

Q

1000: Client was brought to the ED by her
daughter due to increased shortness of breath
this morning. The daughter reports that the
client has been running a fever for the past
few days and has started to cough up
greenish-colored mucous and to complain of
“soreness” throughout her body. The client
was recently hospitalized for issues with atrial

appears slightly labored, and course crackles
are noted in bilateral lung bases. Skin slightly
cool to touch and pale pink in tone; pulse +3
