A nurse is assisting with the care of a client who is in preterm labor and has a prescription for terbutaline 250 mcg subcutaneously, every 20 min. Available is terbutaline 1 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero d applies Do not use a trailing zero)

Given: Prescribed dose: 250 mcg of terbutaline Available concentration: 1 mg/mL Steps to solve: Convert mg to mcg: 1 mg = 1000 mcg 1 mg/mL = 1000 mcg/mL Determine the volume to be administered: Set up a proportion to solve for the unknown volume (X): 1000 mcg/mL = 250 mcg/X mL Cross-multiplying gives us: 1000 mcg x X mL = 250 mcg x 1 mL Simplifying: 1000X = 250 Solving for X: X = 250 / 1000 = 0.25 mL
