Which of the following treatments is indicated for enhancing blood pressure in a hypotensive patient?

Vasopressors are indicated for enhancing blood pressure in a hypotensive patient because they work by causing vasoconstriction and increasing systemic vascular resistance, which elevates blood pressure. In situations of hypotension, particularly in critical care settings or cases of septic shock, vasopressors like norepinephrine or dopamine are often utilized. They directly increase the mean arterial pressure and can restore perfusion to vital organs, thereby improving the patient's stability and overall outcome.

In contrast, calcium channel blockers and beta-blockers can lower blood pressure by reducing heart rate and vasodilation, making them unsuitable for a hypotensive scenario. Diuretics primarily facilitate fluid removal from the body and decrease blood volume, which could further exacerbate hypotension. Therefore, the choice of vasopressors aligns perfectly with the physiological need to elevate blood pressure in hypotensive patients.
