Which of the following catheters is NOT used for total parenteral nutrition?

Appeared in: AIIMS BHOPAL NO- 2018( Shift-2nd)

Explanation

The Swan-Ganz catheter is a pulmonary artery catheter (PAC), a diagnostic tool, not a nutritional delivery device.
Its primary function is to measure hemodynamic parameters like cardiac output and pressures within the heart and pulmonary artery.
The placement and design of a Swan-Ganz catheter are not suitable for the long-term, high-volume infusion of hyperosmolar TPN solutions.

Option B: The Hickman catheter is a tunneled central venous catheter specifically designed for long-term use.
Option C: The Groshong catheter is a type of tunneled central venous catheter used for long-term infusions.
Option D: The Broviac catheter is a tunneled central venous catheter, similar to the Hickman but with a smaller diameter.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types and uses of central venous access devices (CVADs) as background academic context rather than a clinical decision trigger.
Using the correct vascular access device for the intended therapy is critical for patient safety. Using a line for an unintended purpose can lead to severe complications.
A dedicated lumen for TPN is a standard of care to prevent infection and incompatibilities. The ports on a Swan-Ganz catheter are designated for pressure monitoring and specific critical care medications, not nutrition.
What if? If TPN were accidentally infused through a Swan-Ganz catheter's distal port, it could cause pulmonary artery irritation, thrombosis, and dangerously inaccurate hemodynamic readings, compromising patient monitoring.

How to Approach the Question

First, identify the key terms in the question: 'catheter' and 'NOT used for total parenteral nutrition (TPN)'. The word 'NOT' indicates you are looking for the exception.
Recall the primary function of each catheter listed in the options.
Categorize each catheter: Is it for long-term infusion (like TPN) or for short-term diagnostics/monitoring?
The Swan-Ganz catheter is for hemodynamic monitoring. The others (Hickman, Groshong, Broviac) are all types of long-term central lines used for TPN.
Select the catheter that does not fit the purpose of TPN administration.

Concept Tested & Keywords

Concept Tested: Types and uses of central venous access devices (CVADs)
Stem keywords: catheter, total parenteral nutrition, TPN
Lead-in keywords: NOT
Negative lead-in flag: The question asks to identify the option that is an exception.
