What is a potential side effect observed in a client who has started taking a loop diuretic?

When a client starts taking a loop diuretic, a common potential side effect is decreased reflexes. Loop diuretics, such as furosemide, function by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys, leading to increased urination. This can result in electrolyte imbalances, particularly low levels of potassium (hypokalemia). Hypokalemia can affect neuromuscular function, leading to decreased reflexes and muscle weakness.

Other side effects of loop diuretics can include dehydration and hypotension, which may also contribute to lethargy or weakness. Understanding the impact of loop diuretics on electrolyte levels and their subsequent effects on neuromuscular function is crucial for monitoring clients on this medication.
