The nurse understands that which hemodynamic parameters are consistent with hypovolemic shock? Decreased cardiac output and:
Decreased systemic vascular resistance, decreased CVP.
Increased systemic vascular resistance, decreased CVP.
Increased systemic vascular resistance, increased CVP.
Decreased systemic vascular resistance, increased CVP.
The Correct Answer is B
Choice A reason: Decreased systemic vascular resistance, decreased CVP. In hypovolemic shock, the body compensates by increasing systemic vascular resistance to maintain blood pressure. Therefore, decreased systemic vascular resistance is not consistent with hypovolemic shock. Central venous pressure (CVP) would be low due to reduced blood volume.
Choice B reason: Increased systemic vascular resistance, decreased CVP. Hypovolemic shock is characterized by low blood volume, leading to decreased cardiac output and low CVP. The body compensates by increasing systemic vascular resistance to maintain blood pressure, making this the correct answer.
Choice C reason: Increased systemic vascular resistance, increased CVP. While systemic vascular resistance increases, CVP is typically decreased in hypovolemic shock due to the lack of circulating blood volume.
Choice D reason: Decreased systemic vascular resistance, increased CVP. Decreased systemic vascular resistance and increased CVP are not consistent with hypovolemic shock. These parameters might be seen in conditions with different hemodynamic profiles.

Correct Answer is ["A","B","C"]
Explanation
Choice A reason: Tachycardia. In late septic shock, the body attempts to compensate for poor perfusion and low blood pressure by increasing the heart rate. Tachycardia is a common finding as the heart tries to pump more blood to the tissues.
Choice B reason: Lethargic mental status. As septic shock progresses, decreased perfusion to the brain can lead to changes in mental status, such as lethargy or confusion. This reflects the severity of the condition and the impact on the central nervous system.
Choice C reason: Anuria. Anuria, or the absence of urine output, occurs in late septic shock due to severe hypoperfusion and failure of the kidneys. It is a critical sign indicating that the body's organs are shutting down.
Choice D reason: Normal blood pressure. In late septic shock, blood pressure is typically very low due to systemic vasodilation and fluid loss. Normal blood pressure would not be expected at this advanced stage.
Choice E reason: Warm flushed skin. Warm flushed skin is associated with the early stages of septic shock when vasodilation leads to increased blood flow to the skin. In late septic shock, the skin is more likely to be cool and pale due to poor perfusion.
Correct Answer is C
Explanation
Choice A reason:
Elevating the head of the bed is a common practice in patient care but is not directly related to preventing hypovolemic shock. This action can help with respiratory comfort and drainage but does not address fluid balance or blood volume, which are critical in preventing hypovolemic shock.
Choice B reason:
Providing immediate pain relief is important for patient comfort and recovery but does not directly prevent hypovolemic shock. While controlling pain can reduce stress on the body, it does not address the fluid and blood volume concerns central to preventing hypovolemic shock.
Choice C reason:
Monitoring intake and output is crucial in preventing hypovolemic shock, especially in postoperative patients. This helps to ensure that fluid balance is maintained, and any significant losses (e.g., through bleeding, vomiting, or excessive drainage) are promptly addressed. Accurate monitoring allows for early intervention to prevent hypovolemic shock.
Choice D reason:
Practicing careful and consistent hand hygiene is essential for preventing infections, which can lead to septic shock, but it is not directly related to preventing hypovolemic shock. While important, hand hygiene does not specifically address the fluid and blood volume issues involved in hypovolemic shock.
