A nurse is assessing a client who is postpartum and is experiencing hemorrhagic shock. Which of the following findings should the nurse expect?
Explanation & Rationale
Choice A rationale Hemorrhagic shock results from significant blood loss, leading to decreased circulating blood volume and subsequent hypotension. Therefore, hypertension is not expected; instead, the nurse should anticipate hypotension as a classic sign, indicating the body's compensatory mechanisms are failing to maintain adequate perfusion. Systolic blood pressure below 90 mmHg is a common indicator of shock. Choice B rationale Initial compensatory mechanisms in shock, driven by the sympathetic nervous system, usually include tachypnea (increased respiratory rate) to enhance oxygenation and address resulting metabolic acidosis. Bradypnea (abnormally slow respiratory rate, normal 12-20 breaths/min) is a late and ominous sign, reflecting profound central nervous system depression and circulatory failure. Choice C rationale Tachycardia (heart rate >100 beats/min) is an early and compensatory sign of hemorrhagic shock, triggered by the release of catecholamines (epinephrine, norepinephrine). The sympathetic nervous system increases the heart rate and contractility to compensate for the reduced stroke volume caused by the hypovolemia and maintain cardiac output and tissue perfusion. Choice D rationale Hemorrhagic shock causes a severe reduction in renal blood flow due to vasoconstriction and low systemic pressure. This results in oliguria (urine output <30 mL/hr) or anuria, not polyuria. Decreased urine output is a critical indicator of inadequate perfusion to the kidneys and is a classic finding in progressing shock.
