Ace the CCHT Challenge 2025 – Dialysis Dreams Begin Here!

In patients undergoing dialysis, hyperkalemia, or elevated potassium levels, can lead to serious complications, particularly affecting the cardiovascular system. One of the most significant risks associated with hyperkalemia is the potential for heart rhythm disturbances, such as arrhythmias. Elevated potassium levels can disrupt the electrical activity of the heart, leading to conditions like ventricular fibrillation or asystole, which can be life-threatening.

While the other choices might seem plausible at first glance, they do not accurately reflect the ramifications of hyperkalemia in this context. Increased appetite, weight gain, and improved muscle function are typically not associated with hyperkalemia. In fact, patients dealing with hyperkalemia may experience decreased appetite due to various factors related to their condition and treatment. Moreover, hyperkalemia itself often leads to muscle weakness and fatigue, rather than improved muscle function. Understanding these associations is crucial for effectively managing patients who are on dialysis and at risk for complications related to electrolyte imbalances.
