Closely monitor vital signs, including blood pressure, heart rate, and respiratory rate, for at least one hour after administration. Pay particular attention to hypotension, which is a common adverse effect. Measure urine output frequently; the goal is to achieve a sufficient diuresis without causing dehydration.
Electrolyte Monitoring
Serum electrolyte levels, particularly potassium, should be checked before the Lasix push and then regularly, depending on the patient’s condition and risk factors. Hypokalemia is a potential complication, so monitor for signs such as muscle weakness and cardiac arrhythmias. Also, check sodium and magnesium levels as needed, given their interplay with potassium and potential for imbalance following diuretic use.
Fluid Balance Assessment
Assess fluid status meticulously. Monitor intake and output accurately; compare the patient’s weight before and after the Lasix administration to assess fluid loss. Note any signs of dehydration, such as dry mucous membranes, decreased skin turgor, and decreased urine output. Adjust fluid replacement as necessary, guided by the patient’s response.
