Final answer:
Certain antihypertensive medications may need to be adjusted or temporarily stopped on the day of surgery, but not all of them.
Step-by-step explanation:
Hypertension can be managed with a variety of antihypertensive medications. First-line options include thiazide-diuretics, calcium channel blockers, ACE inhibitors, and ARBs. These medications are often used in combination to achieve desired blood pressure levels. Therefore, it is not necessary to hold all antihypertensives on the day of surgery.
