Potassium
- Usual dose is 40meq IV or PO unless level is <2.5. If so, both forms should be given
- 10meq will raise serum level by 0.1
- Intravenous K+ typically runs at 10meq/hour, burns when infused, and may cause phelbitis/sclerosis if run faster
- Oral K+ more quickly absorbed and preferred
- KCl elixir easily swallowed, but tastes terrible, KDur oral tablet is large and hard to swallow
- Serum K+ will not respond if patient has concurrent hypomagnesmia
Magnesium
- Replete if serum level <1.7
- Usual dose is 2g over 1 hour
- If level <than 1.2, double the dose
- Oral repletion may done if level is >1.2 and pt is asymptomatic
- Magnesium oxide 400mg is approximately equal to 2g of MgSO4
Phosphorus
- If <2.4:
- Neutra-Phos 2 packets PO Q6hr x 48hr OR sodium phosphate 30mmol IV
- If <1:
- IV Sodium Phosphate 45mmol should be used
