A nurse is caring for a client who has a fluid and electrolyte imbalance. The nurse knows that the priority goal of taking care of this client is?

Choice A reason: Hypomagnesemia, low magnesium (normal 1.7–2.2 mg/dL), is indicated by the 0.8 mEq/L value. Magnesium is vital for muscle, nerve, and cardiac function. Low levels can cause tremors, seizures, and arrhythmias. The other values (sodium, chloride, potassium) are within normal ranges, making hypomagnesemia the primary imbalance.

Choice B reason: Hyponatremia, low sodium (normal 135–145 mEq/L), is not indicated, as the sodium level is 140 mEq/L, within normal limits. Hyponatremia can cause neurological symptoms like confusion, but the lab values do not support this diagnosis, and magnesium imbalance is the clear abnormality.

Choice C reason: Hyperchloremia, high chloride (normal 98–106 mEq/L), is not present, as the chloride level is 107 mEq/L, just above normal and not clinically significant. Elevated chloride may occur in dehydration or renal issues, but the primary concern here is the significantly low magnesium level.

Choice D reason: Hypokalemia, low potassium (normal 3.5–5.0 mEq/L), is not indicated, as the potassium level is 3.6 mEq/L, within normal range. Hypokalemia causes muscle weakness and arrhythmias, but the lab values point to hypomagnesemia as the primary electrolyte imbalance in this case.

Choice A reason: Homeostasis is the body’s ability to maintain stable internal conditions, including fluid and electrolyte balance. Imbalances, like hypokalemia or hypernatremia, disrupt cellular function, potentially causing arrhythmias or neurological issues. Restoring homeostasis is the priority, as it addresses the root cause, ensuring proper organ function and preventing complications.

Choice B reason: Preventing infection is important but not the priority in fluid and electrolyte imbalances. Infections may occur secondary to other conditions, but the primary concern is correcting imbalances that affect cellular and organ function. Homeostasis must be achieved first to stabilize the client’s physiological state before addressing infection risks.

Choice C reason: Promoting mobility is relevant for overall health but not the priority in fluid and electrolyte imbalances. Imbalances can cause muscle weakness or arrhythmias, but restoring electrolyte levels takes precedence to ensure safe mobility. Without homeostasis, mobility efforts may be unsafe or ineffective due to physiological instability.

Choice D reason: Enhancing nutrition supports overall recovery but is secondary to correcting fluid and electrolyte imbalances. Nutritional deficiencies may contribute to imbalances, but the immediate goal is restoring homeostasis to prevent acute complications like cardiac or neurological dysfunction. Nutrition can be addressed once the client is stabilized.
