## Core Concept
Propofol infusion syndrome (PRIS) is a rare but potentially life-threatening condition associated with the use of propofol, particularly at high doses and for extended periods. It involves a combination of clinical and laboratory findings that reflect severe metabolic and cardiovascular derangements.

## Why the Correct Answer is Right
The correct answer, which is not listed here but implied through the query, relates to understanding what features are *not* typically associated with PRIS. Common features of PRIS include severe metabolic acidosis, rhabdomyolysis, hyperkalemia, and cardiovascular collapse. The syndrome is thought to result from propofol's interference with mitochondrial fatty acid oxidation.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is not provided, but typically, features like metabolic acidosis, rhabdomyolysis, and hyperkalemia are associated with PRIS.
- **Option B:** Similarly, not provided, but if it listed a feature commonly seen in PRIS, it would be incorrect as an "except" option.
- **Option C:** Again, not provided, but if it listed a known feature of PRIS, it would be incorrect here.
- **Option D:** If this option lists a feature not commonly associated with PRIS, it would be the correct choice but is stated as the correct answer here.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that propofol infusion syndrome is more likely to occur with high doses (>83 mcg/kg/min) and prolonged infusion (>48 hours). Early recognition and discontinuation of propofol are crucial. A classic association is the development of metabolic acidosis and rhabdomyolysis.

## Correct Answer: D.
