Appeared in: AIIMS Delhi NO - 2018

Explanation

The solution shown is Total Parenteral Nutrition (TPN), a highly concentrated nutrient solution administered intravenously.
The image correctly depicts the standard administration of TPN through a central venous access device (a catheter in the chest) to deliver nutrients directly into a large vein.
TPN is used for patients with nonfunctional gastrointestinal tracts or those who have high caloric needs that cannot be met orally or enterally.
The yellowish, opaque appearance of the fluid is characteristic of TPN solutions, which contain a mixture of dextrose, amino acids, lipids, electrolytes, and vitamins.

Option B: Enema solutions are administered rectally to cleanse the bowel or deliver medication, not intravenously.
Option C: Enteral feeding solutions are delivered into the gastrointestinal tract via a tube (e.g., nasogastric or gastrostomy tube), not into a vein.
Option D: Colostomy irrigation solution is used to flush a colostomy stoma on the abdomen to regulate bowel function, not for intravenous nutrition.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of Total Parenteral Nutrition (TPN) and its administration method as background academic context rather than a clinical decision trigger.
Nurses must meticulously manage TPN administration due to the high risk of complications, including infection (especially Central Line-Associated Bloodstream Infection - CLABSI), metabolic imbalances (like hyperglycemia or hypoglycemia), and fluid/electrolyte disturbances.
It is a critical nursing responsibility to verify the TPN prescription, check the solution for any precipitates or changes in color, and use aseptic technique for all line connections.
Patient monitoring includes regular blood glucose checks, vital signs, daily weights, and laboratory monitoring of electrolytes, liver function, and triglycerides.

How to Approach the Question

First, carefully analyze the image provided. Identify all the key components of the medical setup shown.
Note the route of administration: The catheter is inserted into the chest, indicating a central venous line, which delivers fluid directly into a large vein near the heart.
Observe the equipment used: An IV bag, tubing, and an electronic infusion pump are visible.
Examine the appearance of the solution in the bag: It is a large volume of an opaque, yellowish liquid.
Correlate these visual cues with the options provided. The combination of a central line, an infusion pump, and a nutrient-rich fluid strongly indicates Total Parenteral Nutrition (TPN).
Eliminate the other options based on their different routes of administration and purposes (rectal for enema, GI tube for feeding solution, stoma for colostomy irrigation).
