Your patient becomes restless and tells you she has a headache and feels nauseous during hemodialysis. Which complication do you suspect?
**Core Concept**
The question tests the student's understanding of complications that can arise during **hemodialysis**, a treatment used for patients with end-stage renal disease. It involves the use of a **semipermeable membrane** to filter waste products from the blood.
**Why the Correct Answer is Right**
Although the correct answer choice is missing, a common complication that presents with restlessness, headache, and nausea during hemodialysis is **dialysis disequilibrium syndrome**. This occurs due to the rapid removal of **urea** from the blood, leading to a shift of water into brain cells and resulting in cerebral edema.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's challenging to address each incorrect choice directly. However, common incorrect options might include hypoalbuminemia or hypokalemia, which, while potential complications of hemodialysis, do not typically present with the acute symptoms described.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **dialysis disequilibrium syndrome** can be prevented or mitigated by slowing the rate of dialysis, especially in patients new to hemodialysis or those with very high **blood urea nitrogen (BUN)** levels.
**Correct Answer:** D. Dialysis disequilibrium syndrome.
