5 True/False Questions

1. 3.5-5.3 → this is the mEq level of calcium

   True        False

2. isotonic dehydration → this occurs when water and electrolytes are lost in equal proportions. results in decreased circulating blood volume and inadequate tissue perfusion.

   True        False

3. calcium → this electrolyte effects the brain. low or too high amounts may cause headache, confusion, seizures, and even coma.

   True        False

4. weight loss → this is most accurate way to measure fluid gain.

   True        False

5. 9-11 → this is the fastest mEq/L that potassium should be given.

   True        False
