A patient's blood gases show a pH of 7.53, PCO2 of 48, and HCO3 of 36 mEq/L. The nurse realizes that the acid-base disorder this patient is demonstrating is which of the following?
Respiratory Acidosis
Respiratory Alkalosis
Metabolic Alkalosis
Metabolic Acidosis
The Correct Answer is C
Choice A reason: Respiratory Acidosis is characterized by a low pH and a high PCO2, which is not the case here.
Choice B reason: Respiratory Alkalosis would involve a high pH and a low PCO2, which is not consistent with the patient's PCO2 level.
Choice C reason: Metabolic Alkalosis is indicated by a high pH and a high HCO3, which matches the patient's blood gas values.
Choice D reason: Metabolic Acidosis would show a low pH and a low HCO3, which is the opposite of this patient's presentation.

Correct Answer is A
Explanation
Choice A reason: Hyperkalemia is a common electrolyte imbalance in prerenal AKI due to decreased kidney function and the inability to excrete potassium.
Choice B reason: Hypernatremia is not typically expected in prerenal AKI unless there is an associated condition causing increased sodium retention.
Choice C reason: Hypercalcemia is not commonly associated with prerenal AKI.
Choice D reason: Hypophosphatemia is less likely in prerenal AKI; hyperphosphatemia is more common due to decreased filtration of phosphate.
Correct Answer is C
Explanation
Choice A reason: Systolic Blood Pressure is not a direct measure of preload; it indicates the pressure in the arteries during the contraction of the heart muscles.
Choice B reason: Mean Arterial Blood Pressure is an average blood pressure in an individual during a single cardiac cycle, but it does not specifically measure preload.
Choice C reason: Central Venous Pressure (CVP) is a direct measure of the blood volume returning to the heart and the ability of the heart to pump the blood into the arterial system, making it a key indicator of preload.
Choice D reason: Systemic Vascular Resistance refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature, and is not a measure of preload.
