Management of Patients with COPD
A client with asthma is prescribed a short acting beta-adrenergic (SABA) for quick relief. Which of the following is the most likely drug to be prescribed?
Albuterol (Proventil), a SABA, is given to asthmatic patients for quick relief of symptoms. Ipratropium bromide (Atrovent) is an anticholinergic. Ipratropium bromide and albuterol sulfate (Combivent) is a combination SABA/anticholinergic, and Fluticasone propionate (Flonase) is a corticosteroid.
bronchospasm
Bronchospasm, which occurs in many pulmonary diseases, reduces the caliber of the small bronchi and may cause dyspnea, static secretions, and infection. Bronchospasm can sometimes be detected on auscultation with a stethoscope when wheezing or diminished breath sounds are heard. Increased mucus production, along with decreased mucociliary action, contributes to further reduction in the caliber of the bronchi and results in decreased airflow and decreased gas exchange. This is further aggravated by the loss of lung elasticity that occurs with COPD (GOLD, 2015).
The nurse, caring for a patient with emphysema, understands that airflow limitations are not reversible. The end result of deterioration is:
Decreased carbon dioxide elimination results in increased carbon dioxide tension (hypercapnia), which leads to respiratory acidosis and chronic respiratory failure. Reference:
A nurse administers albuterol (Proventil), as ordered, to a client with emphysema. Which finding indicates that the drug is producing a therapeutic effect?
In a client with emphysema, albuterol is used as a bronchodilator. A respiratory rate of 22 breaths/minute indicates that the drug has achieved its therapeutic effect because fewer respirations are required to achieve oxygenation. Albuterol has no effect on pupil reaction or urine output. It may cause a change in the heart rate, but this is an adverse, not therapeutic, effect. Reference:
barrel chest
In clients with COPD who have a primary emphysematous component, chronic hyperinflation leads to the "barrel chest" thorax configuration. This configuration results from a more fixed position of the ribs in the inspiratory position (due to hyperinflation) and from loss of lung elasticity. Pigeon chest results from a displaced sternum. Flail chest results when the ribs are fractured. Funnel chest occurs when there is a depression in the lower portion of the sternum; it is associated with Marfan syndrome or rickets. Reference:
Which of the following is accurate regarding status asthmaticus?
Status asthmaticus is a severe asthma episode that is refractory to initial therapy. It is a medical emergency. Patients report rapid progressive chest tightness, wheezing, dry cough, and shortness of breath. It may occur with little or no warning.
In which statements regarding medications taken by a client diagnosed with COPD do the drug name and the drug category correctly match? Select all that apply.
Theophylline, albuterol, and atropine are bronchodilators. Dexamethasone and prednisone are corticosteroids. Amoxicillin, ciprofloxacin, and cotrimoxazole are antibiotics. All of these drugs could be prescribed to a client with COPD.
