- 9.A 20-year-old patient is admitted to the ER while having an asthma attack. She is being treated with 0.63 mg of levalbuterol (Xopenex) by small volume nebulizer. After 45 minutes, the patient's wheezing has decreased in the lower lobes, her respiratory rate has decreased from 32 to 15 per minute, and heart rate has decreased from 120 to 87 beats/min. Based on this information, the physician wants to know what you would recommend.

Switch to 2.5 mg Albuterol
- B.
Decrease the levalbuterol dose to 0.31 mg
- C.
Continue this dose (0.63) of levalbuterol.
- D.
Send the patient home after telling them to always use their inhaler
