Which statement reflects an end point for fluid resuscitation?

• A. A palpable radial pulse
• B. Systolic BP of 120 mm Hg
• C. Improved mental status
• D. Oxygen saturation above 98%

Answer: (A)

Restoring enough circulating volume to perfuse the body is the goal of fluid resuscitation, and the most practical sign of that in the field is a palpable distal pulse, such as a radial pulse. When you can feel a radial pulse, it means arterial pressure is sufficient to push blood to the extremities, which generally reflects adequate perfusion of vital organs.

Targeting a specific blood pressure like 120 mm Hg isn’t reliable in acute resuscitation—the patient can compensate with vasoconstriction or may not sustain that level despite ongoing bleeding. Improved mental status is helpful, but it can be unreliable early on and can lag behind real perfusion changes. Oxygen saturation above 98% indicates oxygenation status, not whether the circulating volume and perfusion are adequate.

So the most direct, practical end point for fluid resuscitation in this context is achieving a palpable radial pulse, signaling adequate perfusion.
