Which of the following is a treatment for improving blood pressure in hypotension?

• A. Vasopressors such as dopamine
• B. Inhaled bronchodilators
• C. IV Fluids
• D. Antibiotics

Answer: (C)

When someone is hypotensive, the first and most direct way to raise blood pressure is to restore intravascular volume with intravenous fluids. Giving an isotonic crystalloid (like normal saline or lactated Ringer's) increases the circulating volume, which improves venous return (preload), boosts stroke volume, and raises cardiac output, leading to higher blood pressure and better perfusion.

This is why IV fluids are the best initial treatment for hypotension. Vasopressors can raise BP more quickly by constricting blood vessels, but they are usually used after fluids have been given or in cases where shock persists despite adequate fluid resuscitation. Inhaled bronchodilators don’t address circulating volume or blood pressure, and antibiotics treat infection but don’t directly raise blood pressure in the immediate sense.
