Answer: 2.5ml

The question is asking how many milliliters should the nurse administer per dose.

The patient need 125mg of cephalexin every 8hour, so the patient would need 125mg of cephalexin per dose.

If the concentration of cephalexin used is 250mg/5ml, then it would need : 125mg / (250mg/5ml) = 2.5ml
