Answer to Question 1

ANS: A
High doses of albuterol may affect beta1 receptors, causing an increase in heart rate. Patients having an asthma exacerbation may over-use their albuterol inhalers when seeking relief. Patients may have wheezing and increased heart rate during an untreated asthma exacerbation, but they will not have tremors and restlessness.

Answer to Question 2

ANS: B
Epinephrine can cause renal vasoconstriction and thereby reduce renal perfusion and decrease urinary output. Epinephrine causes tachycardia and elevates blood pressure. Nausea and vomiting are not expected to occur.
