What is a common side effect of administering potassium via IV?

• A. Nausea and vomiting
• B. Cardiac arrhythmias
• C. Respiratory distress
• D. Fever and chills

Answer: (B)

Administering potassium via IV can lead to cardiac arrhythmias, which is a significant concern due to potassium's critical role in cardiac electrical activity. Potassium levels in the blood directly influence the resting membrane potential of cardiac cells, and both hypokalemia (low potassium) and hyperkalemia (high potassium) can disrupt the normal electrical impulses that control heart rhythm. When potassium is administered intravenously, particularly if done rapidly or in excessive amounts, it can cause a rapid increase in serum potassium levels. This abrupt change can lead to dangerous arrhythmias, such as ventricular fibrillation or asystole, which can be life-threatening conditions. Consequently, monitoring of cardiac function and ensuring potassium is administered at the appropriate rate and concentration is vital to prevent these severe outcomes. Other side effects listed, such as nausea and vomiting, respiratory distress, and fever and chills, are generally less directly connected to potassium administration and do not reflect the most critical or immediate risks associated with IV potassium therapy.
