A nurse is evaluating a client who has fluid volume overload and received furosemide 40 mg IV bolus 1 hr ago. Which of the following findings indicates that the medication was effective?

The client reports increased thirst.

The client's urine output is 250 mL/hr.

The client's heart rate is 100/min.

The client's weight is unchanged.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

Choice A reason:

Dextrose 5% in water (D5W) is a hypotonic solution that provides free water and calories, but no electrolytes. It is used to treat hypernatremia and cellular dehydration, but it can cause fluid shifts from the intravascular to the intracellular space, leading to cerebral edema and decreased blood pressure. This is not appropriate for a client who has dehydration due to vomiting and diarrhea, as they need to restore their intravascular volume and electrolyte balance.

Choice B reason:

Lactated Ringer's (LR) is an isotonic solution that contains sodium, chloride, potassium, calcium, and lactate. It is used to treat fluid loss from burns, trauma, surgery, or sepsis. It also helps to correct metabolic acidosis by providing bicarbonate precursors. This is the best choice for a client who has dehydration due to vomiting and diarrhea, as they need to replace their fluid and electrolyte losses and maintain their acid-base balance.

Choice C reason:

Dextrose 5% in 0.45% sodium chloride (D5W/0.45% NaCl) is a hypertonic solution that provides free water, calories, and sodium. It is used to treat hypovolemia and hyponatremia, but it can cause fluid shifts from the intracellular to the intravascular space, leading to cellular dehydration and increased blood pressure. This is not appropriate for a client who has dehydration due to vomiting and diarrhea, as they already have low blood pressure and cellular dehydration.

Choice D reason:

Dextrose 5% in lactated Ringer's (D5LR) is a hypertonic solution that provides free water, calories, sodium, chloride, potassium, calcium, and lactate. It is used to treat hypovolemia and metabolic acidosis, but it can cause fluid shifts from the intracellular to the intravascular space, leading to cellular dehydration and increased blood pressure. This is not appropriate for a client who has dehydration due to vomiting and diarrhea, as they already have low blood pressure and cellular dehydration.

A. Administer the solution via a central line. B. Monitor serum sodium levels every 4 hours. C. Titrate the infusion rate according to urine output. D. Assess for signs of fluid overload. E. Keep an accurate intake and output record.

Correct Answer is ["A","B","D","E"]

Explanation

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.
