Got a med question that I'm stumped on and I'm probably reading too much in to it as it sometimes the case.Mag sulfate bolus of 4 grams iv over 30 minutes followed by maintenance infusion of 2grams/hour. Pharmacy has provided 1000mL LR with 20 grams mag sulfate.What rate for loading dose?What rate for maintenance dose?Does the 1000mL of LR play a part in this at all? If you want 4 grams in 30 minutes you've got to give 8grams/hr. Am I on the right track? What's next? Thanks for helping a newbie!
