Following 2 motor vehicle collision, an adult client is brought to the emergency department with a blood pressure of 72/50 mm Hg and a blood volume loss of approximately 40%. The nurse should plan care for this client based on which expected response to hemorrhaging?

A) Increased preload that results in generalized peripheral edema: This statement is incorrect. Decreased blood volume due to hemorrhage leads to decreased preload, not increased preload. Generalized peripheral edema is more commonly associated with conditions such as heart failure or kidney disease, where fluid retention leads to increased preload. B) The lowered blood pressure results in a reduction of the heart rate: While it's true that a decrease in blood pressure can trigger compensatory mechanisms such as an increase in heart rate (tachycardia), the specific response mentioned in this option is not entirely accurate. The primary compensatory response to hemorrhage-induced hypotension is typically an increase in heart rate, not a reduction. C) Decreased preload that can lead to decreased cardiac output: Correct. With decreased blood volume (preload), there is less blood returning to the heart during diastole. This leads to decreased ventricular filling and subsequently decreased stroke volume and cardiac output. Decreased cardiac output can contribute to hypotension and inadequate tissue perfusion. D) Increased peripheral resistance resulting from poor renal perfusion: While poor renal perfusion can trigger mechanisms to increase peripheral resistance (such as activation of the renin-angiotensin-aldosterone system), this option does not directly address the primary effect of decreased preload on cardiac output. Increased peripheral resistance alone does not adequately compensate for decreased preload to maintain cardiac output.
