A nurse is assessing a client with suspected hypovolemic shock following trauma. Which clinical finding is most indicative of this condition?

Choice A reason: Blood pressure of 110/70 mm Hg is within normal range and does not indicate hypovolemic shock, which typically presents with hypotension (e.g., <90/60 mm Hg). Early shock may have normal blood pressure, but tachycardia (heart rate 120 beats/min) is a more sensitive indicator of compensatory response to volume loss. Choice B reason: Heart rate of 120 beats/min indicates tachycardia, a hallmark of hypovolemic shock. In trauma, blood loss reduces circulating volume, triggering sympathetic activation to increase heart rate, compensating for decreased cardiac output. This is the most indicative finding, as it appears early and reflects the body’s response to hypovolemia. Choice C reason: Warm, dry skin is not typical of hypovolemic shock, which causes cool, clammy skin due to vasoconstriction from sympathetic activation. Warm skin may occur in distributive shock (e.g., sepsis). Tachycardia is a more specific indicator of hypovolemia, making this finding incorrect for the suspected condition. Choice D reason: Urine output of 40 mL/hr is within normal range (30-50 mL/hr) and does not indicate hypovolemic shock, which typically reduces output (<30 mL/hr) due to decreased renal perfusion. Tachycardia (120 beats/min) is a more immediate and sensitive sign of hypovolemia, making urine output less indicative in early shock.
