Q

Thoracentesis procedure

A

Client must be very still, no coughing or deep breaths
The fluid/blood/exudate is being removed from pleural space
As the fluid is removed, the lung should reexpand
Since you’re removing fluid, the client could go into a fluid volume deficit, so check vitals

Q

What is the purpose of the CDU?

Q

How are the drainage chamber and water seal chamber connected?

Q

Tidaling

A

Fluctuation of rise and fall of water in the water seal tube as the client breathes. Normal, if it stops, it usually means the lung has reexpanded, there is a kink/clot in tubing, or a dependent loop is present

Q

What happens when air exits the water seal chamber?

A

It enters the third chamber called the suction control chamber. This allows any air to be vented out through the air vent found at the top of the suction control chamber

Q

Dry suction system

A

Water is not used to regulate the pressure and therefore has no bubbling. A dial is used to set the desired negative pressure. Increasing the vacuum wall suction will not increase the pressure.

26
Q

What do you do if the CDU tubing becomes d/c

A

Keep another sterile connector at bedside, reconnect as fast as you can

27
Q

What do you do if the CDU falls over and the water leaks out or shifts to the drainage compartment?

A

Do whatever you can to reestablish the water seal. Set the CDU upright, check all the chambers, and fill the water seal chamber to 2cm of water
Have client deep breathe and cough in case any air went into pleural space
If there is not water in the water seal chamber then air can collapse the lung

28
Q

What if the chest tube is accidentally pulled out?

A

Sterile vaseline gauze taped down on 3 sides. Otherwise, every time they take a breath, they will pull air into pleural space

29
Q

When is chest tube bubbling normal?

A

Chest tube connection to suction, gentle continuous bubbling is expected in the suction chamber
If a client with a pneumothorax is coughing, sneezing, or just taking a deep breath and exhaling, you may see intermittent bubbling in the water seal chamber
As long as there is intermittent bubbling, the client needs the chest tube bc air is still leaking out of the pleural space

30
Q

When is chest tube bubbling a problem?

A

If there is continuous bubbling in the water seal chamber, then you have an air leak in the system
Never clamp a chest tube without an order. It could lead to a tension pneumothorax

31
Q

Chest tube removal

A

Have client take a deep breath and hold (valsalva) and place an occlusive petroleum dressing over the site

32
Q

Patho of hemo/pneumothorax

A

Blood or air has accumulated in the pleural space

The lung has collapsed

33
Q

S/S of hemo/pneumothorax

A 
SOB
Increased HR
Diminished breath sounds on affected side
Less movement on affected side
Chest pain
Cough
Blood or air on CXR
Subq emphysema is air trapped in tissue (usually face, neck, chest)
34
Q

Never do what to a penetrating object?

A

Pull it out

35
Q

Tx of hemo/pneumothorax

A

Thoracentesis, chest tubes, daily CXR

36
Q

If a pneumothorax is present and the client has a chest tube, what type of bubbling would be expected in the water seal chamber?

A

Intermittent bubbling

37
Q

Patho of tension pneumothorax

A

Pressure has built up in the chest/pleural space and has collapsed the lung. Pressure pushes everything to the opposite side. (mediastinal shift)

38
Q

What can cause a tension pneumothorax?

A

Trauma, PEEP, clamping chest tube, taping an open pneumothorax on all four sides without an air valve

39
Q

S/S of tension pneumothorax

A

Subq emphysema, absence of breath sounds on one side, asymmetry of thorax, respiratory distress
Can be fatal as accumulating pressure compresses vessels and decreases venous return which decreases CO

40
Q

Tx of tension pneumothorax

A

Large bore needle is placed into the 2nd intercostal space by doc to allow excess air to escape. Then the cause is found, and the chest tubes are inserted

41
Q

Open pneumothorax

A

“Sucking wound”

Opening through chest allows air into pleural space

42
Q

Tx of open pneumothorax

A

Have client inhale and hold or valsalva or hummmmm to increase the intra-thoracic pressure so no more outside air can get into the body
Then, place a piece of petroleum gauze over the area. Tape down 3 sides, 4th side acts as air vent/flutter valve
Have client sit up if possible to expand lungs
Trauma clients stay flat until evaluated for other injuries

43
Q

S/S of ribs and sternum

A

Pain/tenderness
Crepitus (bones grating together)
Shallow respirations
Respiratory acidosis

44
Q

Tx of fx ribs/sternum

A

Non-narcotic analgesic
Nerve block to assist w/ productive coughing
Support injured are with hands
Not recommended to immobilize with chest binder and straps bc it could lead to shallow breathing, atelectasis and pneumonia
Observe for complication such as pneumothorax, hemothorax, and flail chest

45
Q

Multiple rib fx

A

Flail chest

46
Q

S/S of flail chest

A 
Pain
Paradoxical chest movement
To assess chest symmetry, always stand at food of bed to observe how the chest is rising and falling
Dyspnea, cyanosis
Increased pulse
47
Q

Paradoxical chest movement

A

“See-saw chest”

Chest sucks inwardly on inspiration and puffs out on expiration

48
Q

Tx of flail chest

A

Stabilize area, intubate, ventilate

PEEP

49
Q

PEEP

A

Client is on vent
On end expiration, the vent exerts pressure down into the lungs to keep alveoli open
Improves gas exchange and decreases the work of breathing
Expands and realigns ribs so they can start growing back together

50
Q

PEEP can treat what?

A

Flail chest, pulmonary edema, sever hypoxemia, ARDS

51
Q

BiPAP

A

Bi-level Positive Airway Pressure
Used for ARDS in clients with COPD, heart failure, sleep apnea
Exerts different levels of positive pressure support, along with oxygen

52
Q

CPAP

A

Continuous Positive Airway Pressure

Pressure is delivered continuously during spontaneous breathing, for both inspiration and expiration

53
Q

What is CPAP used for?

A

Obstructive sleep apnea

54
Q

What is the priority nu assessment with PEEP, CPAP, or Bi-PAP?

A

Bilateral breath sounds

55
Q

Causes of pulmonary embolism

A

If a client becomes dehydrated, has venous stasis from prolonged immobility or sx, birth control pills, clotting disorders or heart arrhythmias like A-Fib
(All these things make blood thick. Clot forms, travels to lungs. Usually comes from legs)

56
Q

S/S of PE

A 
#1: hypoxemia
Decreased PaO2, give 100% O2
SOB, cough, increased RR
Increased D-dimer, tells if there is a clot located anywhere in the body, not just lungs
Positive VQ scan: most widely used test (ventilation/perfusion scan used to detect an embolus, done in radiology. Looks at blood flow to lungs. Dye is used, remove jewelry from chest area)
Positive spiral CT or CT angiography
Hemoptysis (coughing up blood)
Increase pulse bc hypoxic
Chest pain: sharp, stabbing
CXR shows atelectasis
increased BP in lungs-pulmonary HTN
57
Q

Tx of PE

A

Prevent with ambulation and hydration, SCDs, isometric exercises to decrease stasis
Oxygen
ABGs
Decrease pain
Heparin sodium, warfarin, enoxaparin
Bleeding precautions
Sx
Bedrest
Elevate extremities to increase venous blood return, decrease pooling
TED hose to increase venous return and decrease pooling: often used with SCDs, with a known clot: use TEDs or SCDs on the unaffected extremity or not at all
Warm, moist heat to decrease inflammation

58
Q

Normal aPTT

A

30-40 seconds

59
Q

Normal PT

A

11-12.5 seconds

60
Q

Therapeutic INR

A

2-3

61
Q

Can you be on heparin and warfarin at the same time?

A

Yes

62
Q

Why don’t you put cold on a vein with PE

A

Excessive vasoconstriction

63
Q

Why don’t you put hot on a vein with PE

A

Excessive vasodilation

64
Q

How often do you remove TED hose?

A

Twice a day/once per shift
