Assessment & Drug Effects
• Monitor blood pressure, pulse, peripheral pulses, and urinary output at intervals prescribed by physician. Precise measurements are essential for accurate titration of dosage.
• Report the following indicators promptly to physician for use in decreasing or temporarily suspending dose: Reduced urine flow rate in absence of hypotension; ascending tachycardia; dysrhythmias; disproportionate rise in diastolic pressure (marked decrease in pulse pressure); signs of peripheral ischemia (pallor, cyanosis, mottling, coldness, complaints of tenderness, pain, numbness, or burning sensation).
• Monitor therapeutic effectiveness. In addition to improvement in vital signs and urine flow, other indices of adequate dosage and perfusion of vital organs include loss of pallor, increase in toe temperature, adequacy of nail bed capillary filling, and reversal of confusion or comatose state.
