- Used as an anticonvulsant in the pregnant patient
- Decreases risk of preeclampsia from turning into eclampsia
- Has been used as a tocolytic, but research shows there are other more effective options

- IV bolus given
- IM injections
- Then continuous IV infusion.
- Given in a preeclamptic patient to prevent seizure
- May be continued up to 24 hours postpartum
- Closely monitor mag levels
- Normal serum mag level is 1.5-2.5 mEq/L
- Target therapeutic range for this indication is 2.5-7.5 mEq/L
- Mag over 12 mEq/L can be fatal
- Closely monitor vitals per protocol/order set
- Closely monitor deep tendon reflexes, respiratory function, heart monitor
- Patellar reflex = legs hanging over bed, use reflex hammer to hit the quadricep tendon, do it on both legs and rate. Suppressed reflex can be a sign of impending respiratory arrest!
- 0 – no response
- 1 – sluggish
- 2 – normal
- 3 – more brisk, slightly hyperactive
- 4 – brisk, hyperactive
- Call if RR is less than 12/min
- Check RR + reflex before IV doses. Reflex MUST be present and RR greater than 16 before each IV dose (unless hospital policy reflects otherwise).
- Watch renal function on BMP or CMP and urinary output (med eliminated by kidneys
- Titrating magnesium based on assessment findings
- Calcium gluconate easily accessible
- Antidote for Magsulfate
- Lab values
- Side effects
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.
