After administering 1 L of 0.9% sodium chloride to a postoperative client, which change would indicate successful treatment?

• A. Increased heart rate
• B. Stable blood pressure
• C. Decreased heart rate
• D. Increased urine output

Answer: (C)

The indication of successful treatment after administering 1 L of 0.9% sodium chloride, which is an isotonic saline solution, is reflected in the patient's physiological responses. A decreased heart rate would suggest improved hemodynamics and reduced stress on the heart, particularly after surgery, where the body may have been under significant strain. Administering isotonic saline helps to expand the intravascular volume, potentially improving perfusion and organ function. A decrease in heart rate can signal that the body is stabilizing after the administration of fluids, as the heart is working less strenuously to maintain adequate circulation. This is often a sign that fluid resuscitation has been effective in restoring blood volume and improving hemodynamic stability. While increased urine output may also reflect successful treatment by indicating that the kidneys are perfusing well and that fluid status is adequate, the most direct indicator of improved cardiovascular status in this scenario is a decreased heart rate.
