What does hyperkalemia refer to?

Raised magnesium level in blood
Raised potassium level in blood
Raised sodium level in blood
Low calcium level in blood

The correct answer is: Raised potassium level in blood

Hyperkalemia refers to an elevated level of potassium in the blood. Potassium is a critical electrolyte primarily found inside cells, and it plays a vital role in various bodily functions, including nerve signal transmission and muscle contraction, particularly in the heart. When potassium levels rise above the normal range, it can lead to serious health issues such as cardiac arrhythmias, muscle weakness, and changes in ECG readings. Recognizing hyperkalemia is essential in emergency medicine, as it can result from kidney dysfunction, certain medications, or metabolic disorders. Timely identification and treatment of hyperkalemia are crucial to prevent potentially life-threatening complications.
