During one the nurse’s hourly assessments, Ana is lethargic, her respirations are 8/minute and her DTRs are absent. The nurse identifies this as magnesium sulfate toxicity and after informing the obstetrician the following is ordered: stat magnesium level, stop the magnesium infusion, calcium gluconate, 1 gm IVP over 3 mins. One hour later her magnesium level is 7 mg , therapeutic for preeclampsia (4.7 to 8 mg/dl). The nurse evaluates the intervention. The patient has normal CNS functioning; is alert and oriented; respiratory rate is 16; DTR 2+, and urine output 75 mL so the magnesium sulfate is restarted at 1 g/hr per provider order. With the same solution of 40 g/liter, at what rate (mL/hr) would the nurse set the infusion pump?
