Sutures and Wound Repair/ General Surgery (ABSA) Practice Test

Which statement about parenteral hyperalimentation therapy following GI surgery is false?

1. Catheter is inserted into a large diameter vein with high blood flow

2. Too rapid flow of suction causes hyperglycemia

3. Constant monitoring is necessary

4. Basic solution consists of hypotonic glucose and amino acids

The correct answer is: Basic solution consists of hypotonic glucose and amino acids

The statement that the basic solution consists of hypotonic glucose and amino acids is indeed incorrect. In parenteral hyperalimentation, also known as total parenteral nutrition (TPN), the basic solution typically contains hypertonic glucose, along with amino acids, electrolytes, vitamins, and trace elements. The glucose used is often at a higher concentration, designed to meet the nutritional needs of the patient while managing their blood sugar levels appropriately. Hypertonic formulations allow for a greater caloric intake in a smaller volume, which is critical for patients who may have limited fluid intake capabilities post-surgery. The presence of amino acids in the solution helps to provide essential proteins necessary for tissue repair and recovery, particularly after gastrointestinal surgery. The other statements reflect the standard practices and precautions involved in administering parenteral hyperalimentation therapy post-surgery, such as using a large diameter vein for optimal flow and the necessity of constant monitoring to prevent complications like hyperglycemia.
