Respiratory system meds - exam 3 Flashcards
Methylxanthines Prototype
theophylline (Theolair)
methylxanthines EPA
relaxes the bronchial smooth muscle, promoting bronchodilation
methylxanthines therapeutic use
second line treatment for chronic lung disorders that cause bronchoconstriction (COPD) EBP no longer recommends to use to treat COPD
methylxanthines administration
PO
methylxanthines ADRs
tachycardia, agitation and seizures. Toxicity - ventricular dysrhythmias and convulsions
methylxanthines contraindications and interactions
heart disease, liver dysfunction, and use with caution with seizure disorders
methylxanthines RN intervention and client education
Need to monitor serum blood levels - narrow therapeutic range
inhaled glucocorticoids prototype
beclomethasone (QVAR)
inhaled glucocorticoids EPA
suppress the release of inflammatory mediators and decrease the recruitment of airway eosinophils. Increases the number and sensitivity of beta 2 adrenergic bronchodilators
inhaled glucocorticoids therapeutic use
prophylactic management of asthma with inhaled steroids. Acute asthma flare-ups, systemic corticosteroids used
inhaled glucocorticoids administration
inhaled orally or nasally
inhaled glucocorticoids ADRs
pharyngitis, cough, dry mouth, and candidiasis (thrush)
inhaled glucocorticoids contraindications and interactions
recent live virus immunization and oral candidiasis
inhaled glucocorticoids RN intervention and client education
Rinse mouth and throat with water after using inhaler
Use with a spacer
Educate client on how to administer inhaler
glucocorticoids prototype and other drug names
prednisone
Other: methylprednisone -IV
glucocorticoids EPA
multiple mechanisms of action and each one varies depending on the cell tissue. All affect the inflammatory process to reduce inflammation
Glucocorticoids therapeutic use
decreases inflammatory symptoms and alters the immune response produced by nonendocrine disorders. Used to treat:
Asthma
COPD
Arthritis
Rhinitis
Cancer
Inflammatory bowel disease
Spinal cord injury
Prevention of acute adrenocortical insufficiency
glucocorticoids administration
PO, IM, IV
glucocorticoids ADRs
if take 5 mg of glucocorticoids daily could result in the following AE:
CNS stimulant (jittery inside) - Insomnia
Adrenocortical insufficiency - Fainting, Weakness, Hypotension
Adrenocortical excess
Cardiovascular symptoms - Heart failure, Shock, Cardiac dysrhythmias
Increase appetite (weight gain)
Hyperglycemia… need to monitor patient with diabetes very carefully
Immunosuppressive - delayed wound healing more susceptible to infection
Bone disease
Very fragile skin… paper thin
glucocorticoids Contraindications and interactions
immunosuppression, live vaccines, systemic fungal infections, antibiotic resistant infections
glucocorticoids RN intervention and client education
Treats symptoms, does not cure underlying disease
Take as directed, DO NOT stop taking abruptly
Tapered off
Take with food
Educate on numerous ADRs
anti-inflammatory/leukotriene modifiers prototype
montelukast (Singulair)
leukotriene modifiers EPA
prevents leukotrines from binding to its receptors therefore reducing bonchoconstriction, inflammation, and mucus production
leukotriene modifiers therapeutic use
used in patient with asthma that do not respond to other treatments. Used as a long-acting antiasthmatic med. Only tablet approved for exercise-induced asthma. Can also treat allergies.
leukotriene modifiers administration
PO
leukotriene modifiers ADRs
behavioral changes
BLACK BOX WARNING: neuropsychiatric events have been reported in pts that take this drug (aggressive behavior, hallucinations, insomnia, and suicidal ideation)
leukotriene modifiers contraindications and interactions
liver disease
leukotriene modifiers RN interventions and client education
Not used to manage acute asthma attack
Take 2 hours before exercise to prevent exercise-induced asthma
Take in evening daily to treat allergies
First generation/sedating antihistamines prototype
diphenhydramine (Benadryl)
first gen antihistamine therapeutic use
treat allergic reactions, anaphylaxis, motion sickness, and insomnia
