Q

Shallow breths interrupted by apen and is seen in clients with a CNS disorders is referred to as wht kind of breathing?

A

Cluster breathing (Biot’s)

24
Q

If you have a client that has pneumonia what would be an appropriate nursing diagnoses ?

A

ineffective airway clearance
or
Impaired gas exchange

25
Q

if you have a client that has tachypnea, bradypnea or apena what would be an appropriate nursing diagnoses?

A

ineffective breathing patterns

26
Q

if you have a client who experiences fatigue during ADLs what would be an appropriate nursing diagnoses?

A

Activity intolerance

27
Q

Clients with COPD and Cystic fibrosis lack surfactant which causes what?

A

their lungs to collapse

28
Q

what is an example of a bronchodilator?

A

Albuterol- reduces bronchospasm, opens airways, facilitates ventilation

29
Q

what does an anti inflammatory medication do for the respiratory system?

A

decrease edema and inflammation in the airways, allow better air exchange; ex. Advair, Flovent

30
Q

if you have a client with thick mucus that is difficult to cough up what kind of medication would they possible be prescribed?

A

Expectorants because they will help beak up mucus making it more liquid and easier to expectorate. ex Guaifenesin

31
Q

what do Leukotriene modifiers do?

A

bronchodilators, decrease edema in the airways, decreases inflammatory process; ex. Singulair

32
Q

what are some things to take in to consideration when giving cough suppressants such as Robitussin or Triaminic?

A
  • Do not use with excessive amounts of secretions
  • Do not use if you have diabetes
  • Beware of side effects
33
Q

what is the most common and least invasive treatment for OSA?

A

CPAP continuous positive airway pressure

34
Q

What is the most common sleep apnea?

A

OSA obstructive sleep apnea

35
Q

what are risk factors for sleep apnea?

A

male gender
obesity
age over 40

36
Q

If chest tube becomes disconnected from the collecting system, what is the nursing intervention?

A

Submerge 1” end of tube into sterile saline to maintain the seal

37
Q

If the chest tube is inadvertently pulled out, what is the nursing intervention?

A

Cover wound with occlusive dressing

38
Q

When chest tube is removed and no purse-string suture is in place, what type dressing must cover the insertion site?

A

Occlusive Dressing

39
Q

what types of artificial airway are upper airways?

A

oropharyngeal

nasopharyngeal

40
Q

what types of artificial airway are lower airways?

A

endotracheal tube

tracheostomy

41
Q

what protects the heart and anchors it to surrounding structures?

A

pericardium

Q

what is the outer layer of the heart called?

A

epicardium

Q

what is the atria?

A

upper chambers of the heart

46
Q

what are the ventricles?

A

lower chamber of the heart

Q

what valve-separates the lt. atria and ventricle?

A

49
Q

Pulmonary arteries and aorta are separated by what?
