Respiratory 2 Lecture Flashcards
Define asthma
-Chronic inflammatory disorder of the airways
-Episodic reversible airway obstruction.
-Increased bronchial activity, airway inflammation
When attempting to diagnose asthma, what are some things to consider during the history and physical exam?
-attacks, triggers, allergies, family history
-expiratory wheezing
How will the pulmonary function test show up for asthma?
-It will only show up abnormal during the asthma attack.
-typically decrease in vital capacity and expiratory volumes.
-if poor function, reversible with bronchodilators can be confirmatory
What is albuterol?
short-acting B2-adrenergic agonist that produces bronchodilation within minutes.
What are the adverse effects of albuterol?
- Tachycardia
- Palpitations
- Shakes.
- Tremors
- Anxiety
- Restlessness
- Nausea
What is atrovent?
-An anticholinergic drug that decreases sputum (not a bronchodilator); opens airways so its easier to breathe.
-More effective when given in combination with B2 agonists.
Albuterol + Atrovent = ?
Combivent
What are corticosteroids?
-anti-inflammatory drug that suppresses the inflammatory response and reduce mucus production.
What are some inhaled corticosteroids used for asthma?
Beclovent, flovent, azmacort,pulmicort; long-term control of persistent asthma.
What is the PO medication given for asthma?
Prednisone
What is the IV medication given for asthma?
methylprednisolone (solumedrol)
Are corticosteroids rapid-acting?
No, they decrease inflammation and effects on onset at 4-6 hours post IVP; not the direct meds given for acute exacerbations or emergencies.
What are treatment options for acute asthma attacks?
-Oxygen (NC, FM, NRB)
-Vital signs, pulse ox, auscultate breath sounds, work of breathing
-ABG
-bronchodilating meds via nebulizer STAT (albuterol)
-systemic corticosteroids IV as ordered after bronchodilator
-sputum collection for possible bacterial diagnosis
-help patient control anxiety, stay with patient until attack subsides.
What is the only asthma reliever?
Albuterol
When a patient with asthma is admitted to the emergency department with severe respiratory distress, the nurse anticipates that initial drug treatment will most likely include administration of
Inhaled albuterol
