Medsurg hesi 2 respiratory Flashcards
asthma: the volume of air blown out as hard and fast as possible during the first second of the most forceful exhalation after the greatest full inhalation.
Forced expiratory volume in the first second (FEV1)
asthma: the fastest airflow rate reached during exhalation
Peak expiratory flow
asthma: beta2 agonists, such as albuterol (Proventil, Ventolin), provide rapid relief of acute symptoms and
prevent exercise-induced asthma
asthma: Anticholinergic medications, such as ipratropium are ___ acting and
long-acting and used to prevent bronchospasms
asthma: Methylxanthines, use only when
other medications aren’t working
asthma: salmeterol
Long-acting beta2 agonist, primarily used for attack prevention.
Salmeterol – Advise client to use to
prevent an asthma attack and not at the onset of an attack.
Encourage the client to take prednisone with
food
bronchodilator and anti-inflammatory combination: If prescribed for inhalation administration at the same time, administer the
bronchodilator first in order to increase the absorption of the anti-inflammatory agent.
This is a life-threatening episode of airway obstruction that is often unresponsive to common treatment
Status asthmaticus
Emphysema is characterized by
the loss of lung elasticity and hyperinflation of lung tissue
characterized by the loss of lung elasticity and hyperinflation of lung tissue
Emphysema
Chronic bronchitis is an
inflammation of the bronchi and bronchioles due to chronic exposure to irritants.
Chronic bronchitis is an inflammation of the bronchi and bronchioles due to
chronic exposure to irritants
Alpha1-antitrypsin (AAT) deficiency is a risk factor for
COPD
COPD includes 2 main things
emphysema and chronic bronchitis
Barrel chest or increased chest diameter with
emphysema
COPD: you may have Dependent edema secondary to
right-sided heart failure
COPD findings of extremities
arms and legs thing, clubbing of fingers and toes
In clients who have dark-colored skin or in older adults, oxygen saturation levels
can be slightly lower
COPD findings of hematocrit
An increased hematocrit level is due to low oxygenation levels.
Comparisons of __ to ___ are used to classify COPD as mild to very severe.
forced expiratory volume (FEV) to forced vital capacity (FVC)
Chest x-ray and COPD
not often used to dx early stages, more for the advanced disease
a special enzyme produced by the liver that helps regulate other enzymes (that help breakdown pollutants) from attacking lung tissue.
AAT
COPD: Increased work of breathing increases
caloric demands
COPD: Dyspnea decreases energy available for eating, so
soft, high-calorie foods should be encouraged
For pursed lip breathing, instruct the client not to:
puff the cheeks
Incentive spirometry: Instruct the client to keep a tight mouth seal around mouthpiece and to inhale and
hold breath for 3 to 5 seconds
It is important to recognize in COPD that low arterial levels
of oxygen serve as the primary drive for breathing
Omalizumab (Xolair) can cause
anaphylaxis
COPD: Encourage the client to eat __ ___ foods to promote energy
high-calorie
cor pulmonale
Right-sided heart failure
Air trapping, airway collapse, and stiff alveoli lead to increased
pulmonary pressures (and eventually cor pulmonale, which is right side failure)
COPD: Blood flow through the lung tissue is difficult. This increased workload leads to
enlargement and thickening of the right atrium and ventricle. (and eventually cor pulmonale, which is right side failure)
Right-sided heart failure (cor pulmonale): finding of palpation
liver enlarged
TB: The risk of transmission decreases after _____ of antituberculin therapy.
