just need help on a quick short essay

The physician prescribes the following: draw STAT magnesium (Mg) level; if below 1.4 mg/dl, give magnesium sulfate 3 g in 100 ml normal saline (NS) over 3 hours; give KCl 40 mEq in 100 ml NS IV piggyback (IVPB) over 4 hours now; and give calcium gluconate 2 g in 100 ml NS IVPB over 3 hours.
The laboratory is called to draw a STAT Mg level.

  1. Given that potassium chloride (KCl) and calcium gluconate are compatible, would you mix them in the same bag of NS? State your rationale.
