mechanism - answer✔smoking
what is the desired outcome for COPD - answer✔clear, even, non-labored breathing while
maintaining optimal oxygenation
an abnormal distention of airspaces beyond the terminal bronchioles and destruction of the walls
of the alveoli - answer✔pulmonary emphysema
the impaired carbon dioxide and oxygen exchange that occurs with pulmonary emphysema
results from what - answer✔the destruction of the walls of the alveoli

what will a chest x-ray of someone with emphysema look like - answer✔hyperinflation with
flattened diaphrams
what might the nails of someone with COPD look like - answer✔clubbing
why do we check for JVD in patients with COPD - answer✔they can develop right sides heart
failure
why do we want to use caution when putting COPD patients on oxygen - answer✔it can increase
CO2 retention and causes vasodilation
what are the two major life-threatening complications of COPD - answer✔respiratory failure
respiratory insufficiency
not able to draw in or exhale the volumes needed, respiratory drive is completely wiped out -
answer✔respiratory failure
can be acute or chronic and may need ventilator support until other acute complications can be
treated - answer✔respiratory insufficiency

what is the most common cause of cor pulmonale - answer✔pulmonary HTN
interventions to decrease thick sputum - answer✔maintain adequate hydration
provide humidified O2
suction only if needed
vibrating ositive expiratory pressure device
what can excessive suctioning cause - answer✔airway trauma
what should we do for someone in tripod position - answer✔ABG
supplemental O2
why should COPD patients avoid drinking before and excessivley during meals - answer✔to
make them not feel as full
how many meals should a patient with COPD eat daily - answer✔6 small meals
the intake of this needs increased if a patient has COPD - answer✔calories and protein
what foods should be avoided if they have COPD - answer✔fibrous foods
carbohydrates
why should patients with COPD avoid carbohydrates - answer✔they will increase CO2
production and increase risk for acidosis
what should patients with SOB do before eating - answer✔rest
relieve bronchospasms by altering the smooth muscle tone and reduce airway obstruction by
allowing increased O2 distribution throughout the lungs and inproving alveolar ventilation -
answer✔bronchodilators

transplantation
what type of acid-base imbalance will COPD cause - answer✔respiratory acidosis
large blood clot in the lungs will significantly impair perfusion of gas exchange and oxygenation
- answer✔pulmonary embolism
the obstruction of the pulmonary artery or one of its branches by a thrombus that originates
somewhere in the venous system or right side of heart - answer✔pulmonary embolism
thrombus formation in the deep veins, usually in the calf or thigh, espcially in patients with
peripherally inserted central catheters - answer✔deep vein thrombosis

alveolar dead space is increased - answer✔obstruction
the area recieves little to no blood flow and gas exchange is impaired - answer✔impairment
various substances are released from the clot and surrounding area that cause constriction pf the
blood vessles and results in pulmonary resistance - answer✔constriction
consequences of PE - answer✔increase in PA pressure
increase in right ventricle workload
when the workload of the right ventricle exceeds the limit, what may happen - answer✔failure
