Answer to Question 1

c

Answer to Question 2

D
A beta2 antagonist would be appropriate for a patient with a sustained heart rate of 121/minute, because the effects of the drug would result in a decrease in the workload on the heart and a re-duction in the heart rate.
A beta2 agonist is indicated for preterm labor, not an antagonist. An antagonist would relax the uterus, possibly resulting in delivery of a preterm infant.
A beta2 antagonist would result in inhibition of glycogenolysis, which would help raise the low blood glucose and thus would be contraindicated for this patient.
A beta2 antagonist is contraindicated in a patient with an exacerbation of asthma.
