A nurse is preparing to administer ticarcillin/clavulanate 3.1 g by intermittent IV bolus over 30 min. Available is ticarcillin/clavulanate in 50 mL Normal Saline (NS). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the IV pump rate for administering ticarcillin/clavulanate 3.1 g over 30 min in 50 mL NS, we first convert 30 minutes to hours (30/60 = 0.5 hours). Then, we divide the total volume (50 mL) by the total time (0.5 hours) to get the mL/hr rate (50 mL / 0.5 hours = 100 mL/hr). Therefore, the nurse should set the IV pump to deliver 100 mL/hr to administer the medication correctly. Choice B (100) is correct because it represents the calculated infusion rate. Choices A, C, and D are incorrect as they do not match the calculation.
