Example:

A client is receiving care at the clinic.  Her doctor has prescribed an iron supplement and an increased amount of Vitamin C in her diet.  The nurse understands that the best rationale for increasing Vitamin C in the client's diet is:

a.  it will help decrease the content of iron absorbtion inhibitors

b.  it decreases bioavailability of dietary iron

c.  ascorbic acid aids in the absorption of dietary nonheme iron

d.  it prevents the formation of insoluble and unabsorbable iron compounds
