Sample item

During laparotomy with ongoing blood loss, which finding most strongly suggests inadequate circulating volume requiring reassessment and resuscitation?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Falling blood pressure with tachycardia and decreasing urine output

Hypovolemia commonly causes tachycardia, hypotension, reduced organ perfusion, and oliguria, though no single sign is sufficient alone. Blood loss should be quantified and treatment guided by the clinical picture, monitoring, and laboratory data.

Option by option

  • A. Stable blood pressure with warm peripheries

    These findings do not by themselves suggest evolving hypovolemic shock.

  • B. End-tidal CO2 rising after ventilation is reduced

    End-tidal CO2 can be influenced by ventilation and metabolism; the stated change is not the most direct hypovolemia pattern.

  • C. Falling blood pressure with tachycardia and decreasing urine output (correct)

    Correct. This cluster is consistent with reduced circulating volume and hypoperfusion.

  • D. An isolated temperature of 36.8 C

    A normal isolated temperature does not assess intravascular volume.
