A patient with chronic kidney disease is at risk for developing which of the following electrolyte imbalances?
Decrease in the concentration of calcium in the glomerulus.
Increase in the concentration of potassium in the blood.
Decrease in the concentration of sodium in the blood.
Increase in the concentration of magnesium in the blood.
The Correct Answer is B
A patient with chronic kidney disease is at risk for developing an increase in the concentration of potassium in the blood.
The kidneys play a pivotal role in the regulation of electrolyte balance.
With the progressive loss of kidney function, derangements in electrolytes inevitably occur and contribute to poor patient outcomes123.
Choice A is incorrect because calcium concentration is not regulated in the glomerulus.
Choice C is incorrect because chronic kidney disease can result in either an increase or decrease in sodium concentration in the blood.
Choice D is incorrect because chronic kidney disease does not necessarily result in an increase in magnesium concentration in the blood.
