IVF and K

 Q: Patients with hyperkalemia should be given saline as intravenous fluid (IVF)? (select one)

A) with D-5 

B) without D-5

Answer: A

Usually, IVF resuscitation is sufficient with normal saline. But in patients with potassium level trending towards higher side (hyperkalemia) adding dextrose with saline may help. Dextrose stimulates the insulin release. It increases the entry of potassium into the cell and helps to lower serum hyperkalemia.
