The nurse caring for a client reviews the medical record and determines the client is at risk for developing a potassium deficit because of which situation?

Hyponatremia is a condition where the serum sodium level is below 135 mEq/L, which can affect the normal functioning of cells, muscles, and organs.

Administering intravenous fluids with a high sodium content can help restore the sodium balance and prevent complications such as confusion, seizures, and coma.

Choice A is wrong because encouraging the patient to consume a low-sodium diet would worsen the hyponatremia and increase the risk of electrolyte imbalance.

Choice C is wrong because administering a diuretic medication to increase urine output would cause further fluid and sodium loss and exacerbate the hyponatremia.

Choice D is wrong because encouraging the patient to increase fluid intake would dilute the sodium concentration and lower the serum sodium level.

Acute renal injury (ARI) is a term for a reversible syndrome that results in decreased glomerular filtration rate (GFR) and oliguria. GFR is a measure of how well the kidneys filter blood and oliguria is a condition of producing less than normal amounts of urine.

Choice B is wrong because chronic renal injury (CRI) is not a reversible syndrome, but a progressive loss of kidney function over months or years.

Choice C is wrong because end-stage renal disease (ESRD) is not a reversible syndrome, but a condition where the kidneys have lost most or all of their function and dialysis or transplantation is required.

Choice D is wrong because acute tubular necrosis (ATN) is not a term for a syndrome, but a specific type of acute kidney injury that involves damage to the tubules, the part of the nephron that reabsorbs water and solutes from the filtrate.
