Which clinical finding would a nurse associate with hypokalemia?

Hypokalemia, which is characterized by low levels of potassium in the blood, can lead to several physiological changes in the body. One of the most notable clinical findings associated with hypokalemia is muscle weakness. Potassium plays a crucial role in muscle contraction, and its deficiency can impair neuromuscular transmission. As a result, individuals with hypokalemia may experience weakness, particularly in the muscles of the limbs and, in more severe cases, the respiratory muscles. This weakness occurs because lower potassium levels reduce the excitability of muscle cells, ultimately leading to decreased muscle strength and function.

Understanding this clinical symptom is vital for nurses and healthcare providers, as recognizing muscle weakness in patients can prompt further assessment of potassium levels and appropriate interventions to correct the deficiency.
