The most frequent trace mineral deficiency developing in a patient receiving parenteral alimentation is a deficiency of: (A) Ca, (B) Chromium, (C) Cobalt, (D) Zinc
Answer is D. Zinc deficiency is marked by an eczematoid rash either diffusely or in interiginous areas. A microcytic anemia can develop from a lack of copper and glucose intolerance and may be associated with a lack of chromium. Daily administration of trace metal supplements obtes these problems.
