Which of the following is a sign of potential dysrhythmias related to electrolyte imbalance?

The presence of potassium levels of 5.4 mEq/L is indicative of possible dysrhythmias related to electrolyte imbalances. In this scenario, while 5.4 mEq/L is still within a range that may be considered slightly elevated, it is crucial to understand that dysrhythmias often arise from abnormalities in electrolyte levels, specifically potassium.

Normal potassium levels typically range from 3.5 to 5.0 mEq/L, with levels creeping slightly above 5.0 mEq/L, as seen here, beginning to raise concerns about potential impacts on cardiac function. Levels above this threshold can lead to increased risk for serious cardiac issues, including dysrhythmias. Elevated potassium levels, or hyperkalemia, can cause changes in the heart's electrical activity, leading to symptoms such as palpitations, arrhythmias, or even cardiac arrest in severe cases.

In contrast, potassium levels lower than the normal range, such as 3.2 mEq/L, may also show a risk for dysrhythmias but would indicate a different aspect of electrolyte imbalance known as hypokalemia. Potassium levels of 4.0 mEq/L are within normal limits and thus unlikely to contribute to dysrhythmic
