Regulation of Electrolytes
Regulation of Electrolytes ( 5 Questions)
A nurse is preparing to administer IV fluids to a client who has dehydration. The nurse should select a solution that contains which of the following electrolytes to regulate ECF balance and vascular volume?
Potassium is the major cation in the intracellular fluid (ICF), not the extracellular fluid (ECF) It is important for nerve and muscle function, but it does not regulate ECF balance and vascular volume.
Calcium is a cation that is mostly found in bones and teeth, but also plays a role in muscle contraction, blood clotting, and enzyme activity. It does not regulate ECF balance and vascular volume.
Chloride is the correct answer. It is the major anion in the ECF and it helps to maintain osmotic pressure, acid-base balance, and fluid volume. It often accompanies sodium in fluid replacement therapy.
Phosphate is an anion that is mostly found in bones and teeth, but also participates in energy metabolism, acid-base balance, and nucleic acid synthesis. It does not regulate ECF balance and vascular volume.
Choice A reason:
Potassium is the major cation in the intracellular fluid (ICF), not the extracellular fluid (ECF) It is important for nerve and muscle function, but it does not regulate ECF balance and vascular volume.
Choice B reason:
Calcium is a cation that is mostly found in bones and teeth, but also plays a role in muscle contraction, blood clotting, and enzyme activity. It does not regulate ECF balance and vascular volume.
Choice C reason:
Chloride is the correct answer. It is the major anion in the ECF and it helps to maintain osmotic pressure, acid-base balance, and fluid volume. It often accompanies sodium in fluid replacement therapy.
Choice D reason:
Phosphate is an anion that is mostly found in bones and teeth, but also participates in energy metabolism, acid-base balance, and nucleic acid synthesis. It does not regulate ECF balance and vascular volume.
