Deficiency of following elements is seen with hyperalimentation except
**Core Concept**
In hyperalimentation, also known as total parenteral nutrition (TPN), a solution of essential nutrients is administered intravenously to meet the body's nutritional needs. This can lead to deficiencies of certain elements that are not adequately supplemented in the formula.
**Why the Correct Answer is Right**
Hyperalimentation often involves the administration of a balanced solution of carbohydrates, proteins, fats, vitamins, and minerals. However, certain elements like chromium, manganese, and selenium are commonly not included in the standard TPN formula, leading to their deficiency in patients undergoing hyperalimentation. Chromium plays a crucial role in carbohydrate and lipid metabolism, while manganese is involved in enzyme function and antioxidant defenses. Selenium is an essential component of selenoproteins, which have antioxidant properties and are involved in immune function.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as chromium, manganese, and selenium are not typically supplemented in standard TPN formulas.
**Option B:** This option is incorrect as chromium, manganese, and selenium are not commonly included in standard TPN formulas.
**Option C:** This option is incorrect as chromium, manganese, and selenium are not typically supplemented in standard TPN formulas.
**Clinical Pearl / High-Yield Fact**
It is essential to note that deficiencies in chromium, manganese, and selenium can lead to a range of clinical complications, including impaired glucose metabolism, immune dysfunction, and increased oxidative stress.
**Correct Answer: A. Chromium, manganese, and selenium.**
