The doctor's orders are"
(1) NaHCO3 1amp in NS 1000 ml to infuse @ 42 ml/hr.
(2) Regular insulin 10 units IVP X 1 dose
(3) Insulin 25,000 units in D5W 250 ml to infuse @ 10 ml/hr.
The nurse received the orders and changed the insulin drip to a heparin drip without notifying the doctor.
Can anyone help me identify the medication errors in this case study? I am a brand new nursing student and was given this assignment to do ... we haven't covered the diabetes chapters yet and I am going nuts with reading about insulin, the different strengths, etc. I do see that changing the heparin drip was a problem! But i am stuck on the NaHCO3 ... wouldn't that bring down the patient's K levels? His K levels are resting at a normal value right now. Can anyone explain the combo insulin therapy to me? I am going to hit the books and see what i can find. I'll be checking back frequently.
