An Asthmatic Patient in Severe Distress with Wheezing and Dyspnea

An asthmatic patient in severe distress with wheezing and dyspnea is admitted to the emergency department. After a conducting a full assessment and obtaining a pretreatment baseline, you start the patient on albuterol with a small-volume jet nebulizer. You should continue assessing and documenting all appropriate variables before and after each treatment until what point?

A) The patient's symptoms are relieved or the peak expiratory flow rate (PEFR) /forced expiratory volume in 1 second (FEV_l) exceeds 70% of "personal best."
B) The patient's wheezing disappears and the intensity of breath sounds decreases.
C) The patient's symptoms are relieved or the PEFR/FEV_l returns to the predicted normal.
D) The patient's SpO₂ is above 90% and the PEFR/FEV_l returns to the predicted normal.
