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 weigh the client to determine the rate of the terbutaline infusion.
The nurse should increase the drip rate of the infusion by 5 mL/hr when titrating the dosage.
The nurse should initiate the infusion of terbutaline if the client has five or more contractions in 1 hr.
The Correct Answer is D
Choice A reason: Ensuring that the rate of the client's terbutaline infusion does not exceed 18 mg/hr is incorrect. The prescription specifies the maximum rate as 30 mcg/min, not 18 mg/hr. The units are different, and the prescribed rate is much lower than 18 mg/hr. Terbutaline is typically administered in micrograms per minute, and the nurse should follow the specific rate and titration instructions provided in the prescription.
Choice B reason: Weighing the client to determine the rate of the terbutaline infusion is not necessary according to the prescription. The dosage and titration instructions are based on the number of uterine contractions and not on the client's weight. While weight-based dosing is common for some medications, this prescription provides clear guidelines for adjusting the infusion rate based on the client's contraction pattern.
Choice C reason: Increasing the drip rate of the infusion by 5 mL/hr when titrating the dosage is incorrect. The prescription specifies increasing the infusion rate by 5 mcg/min every 10 minutes until contractions stop, not by 5 mL/hr. The nurse should follow the prescribed titration instructions, which are based on micrograms per minute, to ensure the correct dosage and avoid potential complications.
Choice D reason: This is the correct interpretation of the prescription. The nurse should initiate the infusion of terbutaline if the client has five or more contractions in 1 hour. The prescription indicates that the infusion should start at 2.5 mcg/min and be increased by 5 mcg/min every 10 minutes until the contractions stop, with a maximum rate of 30 mcg/min. This approach helps manage uterine contractions effectively and ensures the client receives the appropriate dosage based on their contraction pattern.

Correct Answer is ["2500"]
Explanation
Step 1: Convert liters to milliliters.
1 liter is equal to 1000 milliliters. Therefore, we can convert 2.5 liters to milliliters as follows:
2.5 liters * 1000 milliliters/liter = 2500 milliliters
Step 2: Round the answer to the nearest whole number.
The answer is 2500 milliliters. Since we are instructed to round to the nearest whole number, we do not need to make any changes.
Therefore, the nurse should administer 2500 mL of lactated Ringer's to the client.
Correct Answer is ["0.5"]
Explanation
Volume = Dose / Concentration Volume = 15 mg / 30 mg/mL
Volume = 0.5 mL
