Chapter 33: Asthma, Bronchoconstriction Flashcards
Albuterol (what)
adrenergic bronchodilator, is a rescue medication
Albuterol stimulates beta2-adrenergic receptors in the smooth muscle of bronchi and bronchioles
Albuterol (use)
albuterol treats or prevents bronchospasm in people with asthma and other reversible obstructive airway diseases and prevents exercise-induced
bronchospasm
Albuterol (side effects)
Muscle tremors most frequent
symptoms of CNS stimulation
beta-blockers inhibit effect
Albuterol (assessment)
decreased dyspnea, wheezing, and respiratory secretions;
relief of bronchospasm and wheezing; reduced rate and improved quality of respirations and pulmonary function
Albuterol (pt teaching)
help patients recognize acute asthma attacks
Asthma attacks are treated by a fastacting, inhaled, short-acting bronchodilator
Avoiding infections will prevent acute asthma attacks
Albuterol (interventions)
Thyroid hormones, theophylline, and some cold products can
enhance the stimulatory adverse effects of the drug
Caffeine-containing products, such as coffee, tea, or cola
drinks, can also increase the adverse effects of cardiac and CNS stimulation
Use of Epinephrine
administered in acute attacks of
bronchoconstriction
given in inhaler or nebulizer, works in 5 minutes lasts for 4 hours
Use of Cromolyn
medication for prophylaxis of acute asthma attacks in
patients with mild, persistent asthma If pt is renal or hepatic impaired
Use of Ipratropium Bromide
used in the long-term management of asthma and other conditions producing bronchoconstriction, such as chronic bronchitis and emphysema
Use of Psuedoephedrine
Must be prescribed
Used for the common cold, provides temporary relief of symptoms associated with nasal congestion due to the common cold, allergies, and sinuses
Inhaler Use
Shake well, sit up, deep breath in for 3-5 seconds and press down on inhaler, hold breath for 10 seconds, exhale slowly.
Rinse mouth after use and wait 3-5 minutes before using again
Theophylline (use)
relaxes bronchial smooth muscle, promoting bronchodilation, and
suppresses airway responsiveness to stimuli that trigger bronchospasm
Theophylline (administration)
the therapeutic range is 5–15 mcg/mL; toxic levels are 20
mcg/mL or above (smokers usually need higher doses)
Theophylline (overdosing)
If overdose is identified
within 1 hour of theophylline ingestion, gastric lavage may be helpful if health care providers are unable to induce vomiting
Theophylline (Assessment)
assess for therapeutic serum levels
Assess for negative effects such as: for tachycardia, dysrhythmias, palpitations, restlessness, agitation, insomnia,
nausea
