Q

what should you do for patients receiving isotonic fluids?

A

Document baseline data. Before infusion, assess the patient’s vital signs, edema status, lung sounds, and heart sounds. Continue monitoring during and after the infusion.
Observe for signs of fluid overload. Look for signs of hypervolemia such as hypertension, bounding pulse, pulmonary crackles, dyspnea, shortness of breath, peripheral edema, jugular venous distention, and extra heart sounds.
Monitor manifestations of continued hypovolemia. Look for signs that indicate continued hypovolemia such as, decreased urine output, poor skin turgor, tachycardia, weak pulse, and hypotension.
Prevent hypervolemia. Patients being treated for hypovolemia can quickly develop fluid overload following rapid or over infusion of isotonic IV fluids.
raise HOB so fluids circulate better
if they have edema, elevate the legs
watch if you patient is having more than 80 cc per hour
Elevate the head of the bed at 35 to 45 degrees. Unless contraindicated, position the client in semi-Fowler’s position.
Elevate the patient’s legs. If edema is present, elevate the legs of the patient to promote venous return.
Educate patients and families. Teach patients and families to recognize signs and symptoms of fluid volume overload. Instruct patients to notify their nurse if they have trouble breathing or notice any swelling.
Close monitoring for patients with heart failure. Because isotonic fluids expand the intravascular space, patients with hypertension and heart failure should be carefully monitored for signs of fluid overload.
