A patient has been diagnosed with hypovolemia. Which prescriptions for hydration should the nurse question? Select all that apply
a. 0.9% (normal) saline at 100 mL/hr
b. Lactated Ringer's solution at 100 mL/hr
c. D50W at 100 mL/hr
d. D5W solution at 100 mL/hr
C, D
Hypovolemia occurs when there is a proportional loss of water and electrolytes from the ECF. Lactated Ringer's and 0.9% (normal) saline are isotonic fluids that remain inside the intravascular space, thus increasing volume. The D5W is a hypotonic solution that would pull body water from the intravascular compartment into the interstitial fluid compartment. D50W is used to treat diabetic patients who have severe hypoglycemia (low blood sugar).
