Which assessment finding indicates that an infusion of intravenous epinephrine 4 mcg/min is effective in the treatment of a patient with anaphylactic shock?
1. Reduced wheezing
2. Heart rate 55 and regular
3. Blood pressure 98/50 mm Hg
4. Respiratory rate 28
1
Rationale 1: An expected action for epinephrine is bronchodilation as evidenced by less wheezing.
Rationale 2: Epinephrine increases heart rate.
Rationale 3: Epinephrine increases blood pressure.
Rationale 4: Epinephrine lowers the respiratory rate. This respiratory rate indicates that epinephrine has not been effective.
