REPLETING ELECTROLYTES<\/p>\n\n\n\n
Before repleting, always ask yourself: how\u2019s the patient\u2019s renal function?
<\/p>\n\n\n\n
For decreased renal function: Always error on<\/p>\n\n\n\n
the side of UNDER replacement.

To remember how to replete, remember: 4-3-2<\/p>\n\n\n\n
K (goal around 4.0): usually 10 mEq will give you a rise of 0.1 mEq\/L; IV and PO have an equivalent effect. Fastest infusion time is 10 mEq\/hr through a peripheral line, or 20 mEq\/hr for a central line if on a monitored bed.
<\/p>\n\n\n\n
– Examples:
<\/p>\n\n\n\n
– 3.0 \u2013 100mEq
– 3.5 \u2013 60mEq
– 3.8 \u2013 20mEq
<\/p>\n\n\n\n
Phos (goal around 3.0): choose KPhos or NaPhos. If the patient needs K as well, they will get 4.4 mEq of K for every 3 mmol of Kphos. Be careful in the setting of hypercalcemia.
<\/p>\n\n\n\n
– Examples:
<\/p>\n\n\n\n
– >2.0 \u2013 oral neutraphos 2 tabs po TID x 3 doses
– 1.5- 2.0 \u2013 0.08 mmol\/kg IV over 6 hrs
<\/p>\n\n\n\n
– 0-1.5 \u2013 0.16 mmol\/kg IV over 6 hrs
<\/p>\n\n\n\n
Mg (goal around 2.0): usually 1 gm for each 0.1 mEq\/L. Magnesium oxide can be used PO (4 tabs being equal to 1 gm) but it is not absorbed well.
<\/p>\n\n\n\n
– Examples:
<\/p>\n\n\n\n
– 1.6\u20134gmIV
– 1.8\u20132gmIV
<\/p>\n\n\n\n
Things to keep in mind about Mag:<\/p>\n\n\n\n
1. If you give it PO, so get ready for some diarrhea<\/p>\n\n\n\n
2. If Mag is low, you\u2019ll need to replete that so that your K can also rise<\/p>\n\n\n\n
