The nurse is caring for a patient with severe burns who is receiving IV fluid resuscitation with lactated Ringer's solution. The nurse understands that this type of solution is used for this patient because it:

Choice A reason:

Administer the solution via a central line. This is correct because 3% sodium chloride solution is a hypertonic solution that can cause phlebitis and tissue damage if infused peripherally. A central line can deliver the solution more safely and effectively.

Choice B reason:

Monitor serum sodium levels every 4 hours. This is correct because serum sodium levels can indicate the effectiveness of the therapy and the risk of complications such as hypernatremia or cerebral edema. The normal range of serum sodium is 135 to 145 mEq/L.

Choice C reason:

Titrate the infusion rate according to urine output. This is incorrect because the infusion rate of 3% sodium chloride solution should be titrated according to serum sodium levels, not urine output. Urine output can be affected by other factors such as renal function, fluid intake, and diuretics.

Choice D reason:

Assess for signs of fluid overload. This is correct because 3% sodium chloride solution can cause fluid shifts from the intracellular and interstitial spaces to the intravascular space, leading to fluid overload. Signs of fluid overload include cough, dyspnea, crackles, tachypnea, tachycardia, elevated blood pressure, bounding pulse, elevated central venous pressure (CVP), weight gain, edema, neck and hand vein distention, altered level of consciousness, and decreased hematocrit.

Choice E reason:

Keep an accurate intake and output record. This is correct because intake and output records can help monitor the fluid balance and identify any excesses or deficits. Intake includes oral fluids, intravenous fluids, tube feedings, and blood products. Output includes urine, stool, vomitus, drainage, and insensible losses.

Choice A reason:

Monitoring neurological status is a priority intervention for a client who has overhydration and hyponatremia because these conditions can cause cerebral edema, increased intracranial pressure, and altered mental status. The nurse should assess the client for signs of confusion, lethargy, seizures, and coma, and report any changes to the provider.

Choice B reason:

Administering sodium polystyrene sulfonate is not indicated for a client who has overhydration and hyponatremia. This medication is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestine. It has no effect on sodium levels or fluid balance.

Choice C reason:

Providing oral hygiene frequently is a supportive intervention for a client who has overhydration and hyponatremia, but it is not a priority. Oral hygiene can help prevent dry mouth, infections, and discomfort caused by fluid retention and electrolyte imbalance. However, it does not address the underlying causes or complications of the disorder.

Choice D reason:

Restricting sodium intake as prescribed is an essential intervention for a client who has overhydration and hyponatremia. Sodium intake can affect the serum sodium level and the fluid balance in the body. Excessive sodium intake can worsen fluid retention and edema, while inadequate sodium intake can exacerbate hyponatremia. The nurse should follow the provider's orders regarding sodium restriction and educate the client on how to avoid high-sodium foods and beverages.

Choice E reason:

Encouraging foods high in protein is not appropriate for a client who has overhydration and hyponatremia. Protein intake can affect the serum osmolality and the fluid distribution in the body. High-protein foods can increase the osmotic pressure in the blood vessels, drawing more fluid from the interstitial and intracellular spaces. This can worsen overhydration and hyponatremia by diluting the serum sodium level further. The nurse should consult with a dietitian regarding the optimal protein intake for the client.
