Closely monitor vital signs, including blood pressure, heart rate, and respiratory rate, frequently during the initial hours of Lasix administration and then at regular intervals thereafter. Significant changes warrant immediate attention.
Regularly assess fluid balance: Measure intake and output meticulously. Note daily weights; a decrease indicates effective diuresis. Report any significant weight loss or gain promptly to the physician.
Observe for signs of electrolyte imbalances.
- Hypokalemia: Monitor potassium levels; supplement as needed. Watch for muscle weakness, fatigue, or arrhythmias. Hyponatremia: Monitor sodium levels; adjust fluid management accordingly. Be alert for confusion, seizures, or nausea.
Continuously assess the patient’s respiratory status. Observe for improvement in dyspnea, crackles, and oxygen saturation. Note any worsening of symptoms immediately.
Monitor oxygen saturation levels with pulse oximetry. Auscultate lung sounds for the presence or absence of crackles. Assess respiratory rate and effort.
Assess for other potential side effects such as dehydration, dizziness, and hypotension. Adjust Lasix dosage or provide supportive care as needed.
Document all observations thoroughly and accurately in the patient’s chart. This precise record provides a clear picture of the patient’s response to treatment and helps guide subsequent management decisions.
