A 32-year-old male patient sustains 78% TBSA burn and is currently admitted to the burn unit. Which sequential order would the nurse arrange the events involved in burn shock following a patient's exposure to burns?

Central venous pressure (CVP) is a measurement of the pressure in the central veins, which reflects the blood volume and right-sided cardiac function. High CVP readings may indicate fluid overload or impaired cardiac function, and intervention is necessary to address the underlying cause.
Administering IV diuretic medications can help reduce fluid volume by increasing urine output and promoting fluid elimination. By removing excess fluid, the diuretic medications can help lower the CVP and alleviate the high pressures.
The other options mentioned are not the anticipated actions for addressing high CVP:
A. Increasing the IV fluid infusion rate in (option A) is incorrect because: If the CVP is already indicating high pressures, increasing the IV fluid infusion rate would further contribute to fluid overload and exacerbate the problem. This action would not be appropriate for high CVP readings.
C. Elevating the head of the patient's bed to 45 degrees in (option C) is incorrect because Positioning the patient with the head of the bed elevated is commonly done to prevent complications such as aspiration or improve respiratory function. While it may have other benefits, it does not directly address the high CVP.
D. Documenting the CVP and continuing to monitor in (option D) is incorrect because Documenting the CVP and continuing to monitor is important for ongoing assessment and evaluation. However, in the presence of high CVP readings, intervention is necessary to address the underlying issue rather than solely documenting and monitoring.
Therefore, when a patient's CVP monitor indicates high pressures following surgery, the nurse would anticipate administering IV diuretic medications to help reduce fluid volume and lower the CVP.

Lactate is a by-product of anaerobic metabolism that accumulates when there is insufficient oxygen supply to meet cellular metabolic demands. In the context of severe tissue hypoxia, such as in septic shock, the body may resort to anaerobic metabolism, leading to increased lactate production and elevated lactate levels in the blood.
Elevated lactate levels, typically above 4.0 mmol/L, are indicative of tissue hypoxia and inadequate oxygenation at the cellular level. Higher lactate levels, such as 9.0 mmol/L, suggest more severe tissue hypoxia and increased anaerobic metabolism.
A. Partial thromboplastin time (PTT) 64 seconds in (option A) is incorrect because: PTT is a laboratory test that evaluates the intrinsic pathway of the coagulation cascade. While coagulation abnormalities may occur in septic shock, PTT alone does not specifically indicate severe tissue hypoxia.
C. Potassium 2.8 mEq/L (2.8 mmol/L) (option C) is incorrect because Low potassium levels (hypokalemia) can be a concern in septic shock, but it does not directly indicate severe tissue hypoxia.
D. PaCO2 58 mm Hg in (option D) is incorrect because: PaCO2 refers to the partial pressure of carbon dioxide in arterial blood and is a measure of the respiratory status. While an elevated PaCO2 can be a sign of respiratory acidosis, it is not specific to severe tissue hypoxia.
Therefore, in a critically ill patient with septic shock, an elevated lactate level, such as 9.0 mmol/L, indicates severe tissue hypoxia and inadequate oxygenation at the cellular level
