Final answer:
Propofol is the induction agent most likely to have the same dosing and effect profile in a 50-year-old woman with severe portal hypertension undergoing a TIPS procedure under general anesthesia.
Step-by-step explanation:
For a 50-year-old woman with severe portal hypertension scheduled for a transjugular intrahepatic shunt (TIPS) procedure under general anesthesia, the induction agent most likely to have the same dosing and effect profile as a normal healthy individual is propofol. Propofol is commonly used as an intravenous induction agent for general anesthesia, and its dosage and effects are not significantly altered in patients with severe portal hypertension.
