Correct Answer is A
Explanation
Sodium is the major extracellular electrolyte in the body.
It is responsible for maintaining the extracellular fluid volume, and also for regulation of the membrane potential of cells.
Sodium is exchanged along with potassium across cell membranes as part of active transport.
Choice B is wrong because potassium is mainly an intracellular ion.
It is important for nerve and muscle function, but it is not the predominant electrolyte in the extracellular fluid.
Choice C is wrong because calcium is not the major electrolyte in the extracellular fluid.
Calcium is mostly found in bones and teeth, where it forms a mineral reserve with phosphate.
Calcium also plays a role in muscle contraction, blood clotting, and enzyme activity.
Choice D is wrong because magnesium is not the major electrolyte in the extracellular fluid.
Magnesium is mostly found in bones, where it helps to stabilize the structure of ATP2.
Magnesium also participates in enzyme reactions, nerve and muscle function, and protein synthesis.
Correct Answer is A
Explanation
SIADH is a condition in which your body makes too much antidiuretic hormone (ADH), which controls how your body releases and conserves water.
SIADH makes it harder for your kidneys to release water and causes the levels of electrolytes, like sodium, to fall due to water retention.
This leads to hyponatremia, which is when you have low levels of sodium in your blood.
Choice B is wrong because hypernatremia is when you have high levels of sodium in your blood.
This can occur due to dehydration, excessive salt intake, or kidney problems.
Choice C is wrong because hyperkalemia is when you have high levels of potassium in your blood.
This can occur due to kidney failure, acidosis, or certain medications.
Choice D is wrong because hypokalemia is when you have low levels of potassium in your blood.
This can occur due to vomiting, diarrhea, diuretics, or alkalosis.
