Upon arrival his vital signs are B/P 152/84, P 124, R 42, T. 100.4. You start Mr. Norse on O2 4L/min via nasal cannula and an IV of D/SW at KVO rate of 40gtts/hour. His ABG's are pH 7.31, CO2 26, HCO3 26 and O2 sats at 88% 1. Identify the underlying pathophysiology of asthma. 2. Are Mr. Norse's vital signs acceptable? If not, state the abnormalities which give you concern. 3. State the difference between rescue and control medications for asthma 4. State how bronchodilators work (Pg. 331) 5. State the difference between Beta2-adrenergie agonists and cholinergic antagonists 6. Identify the drug classifications of Vanceril and Atrovent. 1. Are Vanceril and/or Atrovent appropriate for use during an asthma attack? If not state, why. The physician orders albuterol 3mg via nebulization STST. 8. What is the rationale for this order? 9. What is the rational for starting the patient on 02 immediately? 10. What are some of the side effects of bronchodilators and one nursing intervention you can provide to minimize the effects of the drug. 11.
