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 ["A","B","C"]

Explanation

Choice A reason:

The nurse should monitor blood glucose levels because dextrose 10% in water (D10W) is a hypertonic solution that contains glucose and can raise the blood sugar level of the patient. The nurse should check the blood glucose level before and after administering D10W to prevent hyperglycemia or hypoglycemia.

Choice B reason:

The nurse should check for signs of phlebitis at the IV site because D10W is acidic and can cause venous irritation. Phlebitis is inflammation of the vein that can result from chemical, mechanical or bacterial causes. Signs of phlebitis include pain, redness, swelling, warmth and tenderness at the IV site.

Choice C reason:

The nurse should assess for fluid overload because D10W is quickly metabolized, leaving behind water that can move into the interstitial space. Fluid overload can cause edema, dyspnea, crackles, distended neck veins, increased blood pressure and decreased urine output. The nurse should monitor the intake and output, vital signs, weight and breath sounds of the patient.

Choice D reason:

The nurse does not need to evaluate serum sodium levels because D10W does not contain sodium or affect the sodium balance of the patient. D10W is used to provide some nutrition with glucose, not to correct electrolyte imbalances.

Choice E reason:

The nurse does not need to observe for signs of hypoglycemia because D10W is unlikely to cause hypoglycemia unless there is a sudden interruption or discontinuation of the infusion. Hypoglycemia is a low blood sugar level that can cause shakiness, diaphoresis, confusion, weakness, hunger and headache. The nurse should monitor the blood glucose level and administer D10W at a steady rate to prevent hypoglycemia.

A. U waves. B. Absent P waves. C. Elevated T waves. D. Inverted QRS complexes.

Correct Answer is C

Explanation

Choice A reason:

U waves are not a sign of high potassium level, but rather of low potassium level (hypokalemia) Hypokalemia can cause ST segment depression, T wave flattening or inversion, and prominent U waves.

Choice B reason:

Absent P waves are not a sign of high potassium level, but rather of a severe conduction block or atrial fibrillation. High potassium level can cause P wave widening or flattening, and PR prolongation, but not complete disappearance of P waves.

Choice C reason:

Elevated T waves are the most common and earliest sign of high potassium level (hyperkalemia) Hyperkalemia can cause tall, peaked, symmetric T waves that may merge with the QRS complex. This is the correct answer.

Choice D reason:

Inverted QRS complexes are not a sign of high potassium level, but rather of ventricular arrhythmias or myocardial infarction. High potassium level can cause QRS widening and bizarre QRS morphology, but not inversion.
