A nurse is caring for a client who has metabolic alkalosis and is receiving sodium chloride and potassium chloride IV fluids. The nurse should monitor for which of the following complications of this therapy?

Hypernatremia.

Hypokalemia.

Hyperchloremic acidosis.

Hypochloremic alkalosis.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Hypernatremia is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids do not contain excessive amounts of sodium. Hypernatremia is more likely to occur with hypertonic saline solutions or excessive sodium intake.

Choice B reason:

Hypokalemia is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids contain potassium, which can help prevent or correct hypokalemia. Hypokalemia is more likely to occur with diuretic therapy, vomiting, or diarrhea.

Choice C reason:

Hyperchloremic acidosis is a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids can increase the serum chloride level and lower the serum bicarbonate level, resulting in a metabolic acidosis. Hyperchloremic acidosis can also worsen the client's existing metabolic alkalosis by impairing the renal excretion of hydrogen ions.

Choice D reason:

Hypochloremic alkalosis is not a likely complication of sodium chloride and potassium chloride IV fluids, because these fluids do not cause a loss of chloride or an increase in bicarbonate. Hypochloremic alkalosis is more likely to occur with vomiting, gastric suctioning, or diuretic therapy.

Correct Answer is B

Explanation

Choice A reason:

The client reports increased thirst. This is not an indication that the medication was effective, because increased thirst can be a sign of dehydration or electrolyte imbalance caused by excessive diuresis. Furosemide can cause loss of water and sodium, potassium, calcium, magnesium, and chloride in the urine.

Choice B reason:

The client's urine output is 250 mL/hr. This is an indication that the medication was effective, because furosemide is a loop diuretic that inhibits the reabsorption of sodium and water in the ascending limb of the loop of Henle, resulting in increased urine output and decreased fluid volume. A normal urine output is about 30 to 60 mL/hr, so a urine output of 250 mL/hr indicates a significant diuretic effect.

Choice C reason:

The client's heart rate is 100/min. This is not an indication that the medication was effective, because a high heart rate can be a sign of hypovolemia, hypotension, or cardiac stress caused by furosemide. Furosemide can lower the blood pressure and reduce the preload and afterload on the heart, but it can also trigger compensatory mechanisms such as increased sympathetic activity and renin-angiotensin-aldosterone system activation, which can increase the heart rate.

Choice D reason:

The client's weight is unchanged. This is not an indication that the medication was effective, because weight loss is expected with furosemide therapy due to fluid removal. Furosemide can cause a rapid and significant reduction in fluid volume, which can be measured by daily weight changes. A weight loss of 1 kg corresponds to a fluid loss of about 1 L.

A. Hypernatremia. B. Hyperkalemia. C. Fluid volume deficit. D. Cerebral edema.

Correct Answer is D

Explanation

Choice A reason:

Hypernatremia is not a likely complication of fluid therapy for diabetic ketoacidosis (DKA) Hypernatremia occurs when there is a loss of water or an excess of sodium in the body. Fluid therapy for DKA usually involves normal saline and dextrose, which do not cause hypernatremia. In fact, fluid therapy may help correct the dehydration and hyperosmolality that are associated with DKA.

Choice B reason:

Hyperkalemia is also not a likely complication of fluid therapy for DKA. Hyperkalemia occurs when there is an excess of potassium in the blood. Fluid therapy for DKA usually involves insulin infusion, which helps lower the potassium level by driving it into the cells. Insulin also helps lower the blood glucose level and reverse the acidosis that are characteristic of DKA.

Choice C reason:

Fluid volume deficit is a common manifestation of DKA, not a complication of fluid therapy. Fluid volume deficit occurs when there is a loss of fluid and electrolytes from the body due to osmotic diuresis, vomiting, and increased respiratory rate. Fluid therapy for DKA aims to restore the fluid volume and correct the electrolyte imbalances that result from fluid loss.

Choice D reason:

Cerebral edema is a potential complication of fluid therapy for DKA, especially in children and young adults. Cerebral edema occurs when there is an increase in intracranial pressure due to swelling of the brain tissue. Fluid therapy for DKA may cause cerebral edema by altering the osmotic gradient between the blood and the brain, leading to fluid shifts into the brain cells. Cerebral edema can cause neurological symptoms such as headache, confusion, seizures, and coma.
