If fluid resuscitation is performed during shock, what is a likely outcome?

• A. Increased blood pressure
• B. Decreased heart rate
• C. Increased urine output
• D. Decreased respiratory rate

Answer: (C)

Fluid resuscitation during shock is aimed at restoring effective circulating volume, which is crucial for improving tissue perfusion and oxygen delivery. When fluid resuscitation is successful, one of the most significant outcomes is increased urine output. This increase occurs because proper kidney perfusion is restored with improved blood volume and pressure, allowing the kidneys to filter blood effectively and produce more urine.

Adequate urine output is a strong indicator of kidney function and overall fluid status in the body. Therefore, monitoring urine output is critical in patients receiving fluid resuscitation, as it reflects the body's response to treatment and indicates whether perfusion has improved sufficiently to support renal function.
