A nurse is reviewing a prescription to initiate an infusion of terbutaline at 2.5 mcg/min to a client PRN more than four uterine contractions in 1 hr and to increase the infusion by 5 mcg/min every 10 min until contractions stop, not to exceed a rate of 30 mcg/min. How should the nurse interpret this prescription?

The nurse should ensure that the rate of the client's terbutaline infusion does not exceed 18 mg/hr.

The nurse should initiate the infusion of terbutaline if the client has five or more contractions in 1 hr.

The nurse should increase the drip rate of the infusion by 5 mL/hr when titrating the dosage.

The nurse should weigh the client to determine the rate of the terbutaline infusion.
