Your patient has Iron deficiency anemia because of their pica. Which of the following lab results is EXPECTED in this condition?
High serum Iron and Low MCV
High serum Iron and Mean Corpuscular Volume (MCV)
High Total Iron Binding Capacity: Low serum Iron and MCV
None of the above
The Correct Answer is C
A. In iron deficiency anemia, serum iron levels are typically low due to a deficiency in iron. Additionally, the Mean Corpuscular Volume (MCV) is often low because the red blood cells produced are smaller than normal (microcytic).
B. Similar to option A, serum iron levels in iron deficiency anemia would be low, not high. The MCV may be low or normal, but it would not be high due to the production of microcytic red blood cells.
C. In iron deficiency anemia, TIBC is usually high because the body is trying to maximize iron transport in response to low iron levels. Serum iron is low, and the MCV is low due to the production of smaller red blood cells.
D. This option is incorrect because option C accurately describes the expected lab results in iron deficiency anemia.

Correct Answer is ["A","B","D","E"]
Explanation
A. Using a filtered IV line helps remove any particulate matter that could be present in the TPN solution, reducing the risk of complications such as phlebitis or embolism.
B. TPN should have its own dedicated line to prevent incompatibilities and ensure the TPN solution is delivered without interference. Infusing other medications through the same line can lead to complications and reduce the effectiveness of TPN.
C. If TPN gets stopped or runs out, a bag of 5% dextrose in water (D5W) should be hung to prevent hypoglycemia. D10% is too concentrated and can cause hyperglycemia.
D. To minimize the risk of infection and maintain sterility, TPN bags and tubing should be replaced every 24 hours. This helps prevent bacterial growth in the TPN solution.
E. TPN is typically administered through a central line because it allows for the infusion of hypertonic solutions that can irritate peripheral veins. Central lines provide better access to larger blood vessels, reducing the risk of complications.
