Question: 1 / 595

Which of the following symptoms is associated with hyperkalemia?

Muscle spasms

Nausea and vomiting

Hypotension

Bradycardia

Hyperkalemia refers to an elevated level of potassium in the blood, which can significantly affect various physiological functions. Among the symptoms associated with hyperkalemia, one notable manifestation is bradycardia.

Bradycardia, which is the term for a slower-than-normal heart rate, can occur due to the effects of high potassium levels on cardiac muscle cells. Potassium is crucial for maintaining the electrical activity of the heart. An excess can disrupt the normal electrical conduction pathways, leading to a decrease in heart rate. This can have serious implications, including a risk for arrhythmias or even cardiac arrest if potassium levels remain elevated and untreated.

Understanding hyperkalemia is crucial for healthcare professionals, as recognizing these symptoms can facilitate timely interventions to correct potassium levels and prevent further complications.
