## Core Concept
The question pertains to the type of fluid used during a Transurethral Resection of the Prostate (TURP) procedure. TURP is a surgical procedure commonly used to treat urinary problems caused by an enlarged prostate. The fluid used during TURP is crucial as it helps in providing a clear visual field for the surgeon and prevents the absorption of hypotonic solutions.

## Why the Correct Answer is Right
The correct answer, **D. 1.5% Glycine**, is a type of irrigating fluid used during TURP procedures. Glycine is an amino acid solution that is isotonic but becomes hypotonic when absorbed. It is used because it does not conduct electricity, which is beneficial for the electrocautery equipment used during the procedure. Glycine solution helps to minimize the risk of hemolysis, which can occur if a hypotonic solution is absorbed.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because normal saline cannot be used for TURP procedures as it conducts electricity and would interfere with the electrocautery equipment.
- **Option B:** This option is incorrect because while dextrose solutions can be used for certain medical procedures, they are not the preferred choice for TURP due to their potential to cause fluid overload and their conductivity.
- **Option C:** This option is incorrect because although ringer lactate has isotonic properties similar to bodily fluids, its use in TURP is not preferred due to its conductivity and potential for causing fluid overload.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the use of **glycine** during TURP procedures can lead to a condition known as TUR syndrome, characterized by fluid overload, hyponatremia, and potentially life-threatening complications. Monitoring the patient's fluid status and serum sodium levels during and after the procedure is crucial.

## Correct Answer: D. 1.5% Glycine
