monitor abgs levels
vital signs
signs of poor gas exchange

77
Q

what is a pneumothorax ?

A

presence of air in the pleural space

78
Q

what is installed when a patient has a pneumothorax ?

A

chest tube - one of the reasons is accumulation of air that can cause the lung to collapse

79
Q

pneumothorax
causes loss of negative pressure in the lung and lung

what is an open pneumothorax or closed pneumothorax ?

A

open pneumothorax - pleural cavity exposed to outside air such as penetrating wound ( knife stab )

closed pneumothorax - happened inside such as injury to lungs from broken ribs or mechanical ventilation or other med procedures

80
Q

what is the cues for pneumothorax :
small
large

A

small : mild tachycardia and dyspnea

large : resp distress, including shallow, rapid resp; dyspnea ; air hunger; decreased oxygen sat.
no breath sounds on auscultation

81
Q

what is this describing : this is like a pneumothorax but this is blood in the cavity

A

hemothorax

82
Q

what is a hemothorax

A

accumulation of blood in the pleural space that can occur from trauma or med procedures

83
Q

what can happen along with hemothorax ?

A

can happen along with pneumothorax

84
Q

the cues for hemothorax are the as pneumothorax, but what else can occur if a large amount of blood is lost?

A

hypovolemic shock

85
Q

define if this is true. For large hemothorax or tension pneumothorax will require immediate needle aspiration followed by chest tube insertion.for the treatment

A

yes this is true

86
Q

define if this is true in terms of treatment : If small hemothorax and hemodynamically stable then supportive nursing care only. Will resolve spontaneously.

A

yes this is true

87
Q

a chest tube drain placed in the pleural space allows what ?

A

allows lung re-expansion and prevents air and fluid from returning to the chest.

88
Q

pulmonary embolism is the blockage of pulmonary vessels by thrombus ( dead space )

what can this be ?

A

solid, fatty deposit, air

89
Q

what are the risk factors for PE

A

prolonged immobility, surgery, pregnancy, obesity, advancing age, genetic conditions, hx of thromboembolism, smoking, estrogen therapy, hf, fractures ( f.e ) foreign objects ( broken iv catheters )

90
Q

if fat embolism is the cause what is the things you will recognize/analyze when it comes to the cues for PE

A

increase RR
increase HR
increase temp
decrease 02 sats
petechiae over chest

91
Q

true or false. many patients do not present with classic symptoms so PE is often overlooked ( notice small things )

A

true

92
Q

what are the lab assessments and diagnostics we are looking for when it comes to PE

A

ABG’s

general metabolic panel ( for underlying conditions that may affect clotting )

d dimer ( increases with fibrinolysis associated with PE )

troponin and brain natriutic peptide ( bnp ) – prognostic markers of R ventriuclar dysfunction associated with PE

ct scan

93
Q

when does pe drug theraphy begin ?

A

Begins immediately with anticoagulants to prevent embolus enlargement

Type of Anticoag depends on severity of symptoms and size of embolus.

94
Q

with massive PE ( mortality > 65 % ) pts what undergoes this description

A
  • Fibrinolytic tx (tPA to dissolve clot) monitored in ICU while on this. Major risk of hemorrhaging.
95
Q

Low risk PE (mortality 1-3%) what undergoes this description

A
  • Heparin, low molecular weight heparin initiated and on this for 5-10 days.
  • Warfarin initiated on day 1-2 of heparin tx.
  • Treatment with both Heparin and Warfarin continues until INR reaches therapeutic level 2-3.
  • Direct Thrombin inhibitors (riveroxiban apixaban) are becoming more common to use instead of Coumadin
  • Usually on oral anticoags (Warfarin or Direct Thrombin Inhibitors for 3-6 mths.
96
Q

Submassive PE

A
  • Must weigh benefits of thrombolytic tx to risk of bleeding. Treatment controversial.
97
Q

PE
General Nursing Care

A

Position to optimize ventilation (high fowlers)

  • O2 therapy (Type and amount depends on severity)
  • NP, Mask, Mechanical ventilation
  • IV Line for drug therapy and fluids
98
Q
  • Emotional Support - it’s scary when you can’t breathe!
  • Self care while on anticoags (next slide)
    those are also essential when it comes to general nursing care on a pt who has PE
    what are the ongoing Monitoring, we are going to be doing
A
  • Resp status,
  • VS, cardiac dysrhythmias, lung sounds,
  • mental status, confusion
  • DVTs
  • Evidence of bleeding (could be gums, old IV sites, GI, brain)
99
Q

what are the signs that a patient may have bleed in the brain ? gi ?

A

confusion
gi - they could have melena stools , blood pressure will drop

cardiac output is low

100
Q

how can a patient be discharged for pe ?

especially if it is warfarin

A

Can be discharged once hemodynamically stable, hypoxia is resolved, and adequate anticoagulation is achieved.

101
Q

a patient who had pe may be on anticoag therapy for weeks, months, years. Teach the following:

especially if it is warfarin

A
  • Importance of taking take anticoagulants at same time each day
  • Will require frequent regular appointments to monitor INR.
    ——- Vit K can alter effectiveness of anticoagulants (green leafy veggies)
102
Q
  • Teach to monitor for S&S of bleeding, bruising.
  • Teach to use soft bristle toothbrush electric shaver.
  • Non- contact sports, careful with ADLs

these are also very important to teach ur client who had PE

what is the most important ?

A

If bleeding occurs and does not stop within 15 min call EMS ( especially if nose bleed )

lose blood quicky- and probably pass out

103
Q

Take Action: Pulmonary Embolus
surgical therapy

what is embolectomy ?

A

surgical removal, embolus when pt is not a candidate for tPA

104
Q

what are the two surgical theraphy for pulmonary embolus ?

A

embolectomy
inferior vena cava filter

105
Q

what is Inferior Vena Cava Filter

A

Insertion of a filter to vena Cava that traps emboli travelling to lungs from other veins.

106
Q

who are the candidates for inferior vena cava filter

A
  • Can’t take anticoags (i.e. pregnancy)

weight loss and malnutrition

142
Q

pressure on diaphragm from a full stomach causes what ?

dyspnea

143
Q

in copd patients : difficulty breathing while eating leads to what

A

inadequate consumption

144
Q

to decrease dyspnea and conserve energy in copd patients what do we do ?

A
  • Rest at least 30 minutes before eating.

146
Q

define if these are true.
rlly hard to chew when u cannot brethe
do not eat too much at a time - dipahragram - breathing problem
conserve energy - make their meals in advance

A

true when it comes to copd

147
Q

pulmonary rehab programs are rlly good why ?

lungs transplant
Very difficult course of antirejection drugs to follow
what does this mean

A

body rejects it

152
Q

copd : acute exacerbation

Avoid crowds

Up to date pneumonia and flu vaccines

Avoid triggers, stay indoors when air quality poor

156
Q

back and forth if not control
triggered if they have resp infection - get to dr and get abx
this is true amongst acte exacerbation in copd pts.

A

yes

157
Q

acute exacerbation copd
will require what ?

require hospitalization and increased monitored care

158
Q

acute exacerbation COPD
increase the medication and add medication to get under control
what does this mean ?

A

Medication will be “stepped up”until stable.
o Increase Inhaled bronchodilators
o Antibiotics if infection present
o Oral systemic steroids

159
Q
  • Oxygen will be required and stepped up as needed
  • Promote rest to allow energy for breathing and eating.
  • Raise HOB
  • Ventilation and intubation may be required if acute respiratory failure

are these true when it comes to acute exacerbation

A

yes

160
Q

COPD : cor pulmonale
give a brief description

A

lungs are not working well - vasoconstriction

lead to resistance and pulmonary hypertension and end up right sided hf

161
Q

what is cor pulmonale ?

A

air trapping and stiff alveolar walls increase lung tissue pressure and narrow blood vessels making blood flow and perfusion difficult

162
Q

recall that cor pulmonale :
air trapping and stiff alveolar walls increase lung tissue pressure and narrow blood vessels making blood flow and perfusion difficult

what does this cause ?

A

causes right side of heart to work harder to pump the blood to lungs.

Right chamber of heart enlarges thickens and becomes inefficient.

Causes blood to back of to central venous system
* Distended neck veins
* Peripheral swelling

163
Q

thicken and enlarged not pumping adequately can eventually cause what?

A

dysrhythmias

164
Q

Cardiac Dysrhythmias define the description for cor pulmonale

A

Decreased oxygenation of heart muscle can cause dysrhythmias

165
Q

copd patients could be prone to depression/anxiety/panic

high rates of depression anxiety : >40% report anxiety/depression

depression relates to ?

A

depression :
related to loss associated with disease

related guilt of smoking

convey understanding

support groups, counselling, mediation, hypnosis therapy

166
Q

what can cause anxiety ?

A

dyspnea causes anxiety - scary when u cannot breathe

pt should have a plan for when systems flare

167
Q

COPD: Discharge Teaching:
just read :
* Pace and plan ADLs with rest periods.
* Encourage smoking cessation
* Promote hand hygiene, stay away from crowds
* Encourage influenza, pneumonia vaccines
* Seek medical attention promptly if S&S of infection begin.
* Follow medication schedule, understand use, how to take inhalers properly.
* Take long-acting medications to prevent exacerbations. Take short acting inhalers before activity (exercise, eating) or when feeling SOB.
* Exercise using pursed lip breathing. Walking daily for 20 min is best.
* Home 0 2 if needed.
