Acid-Base Balance Practice Questions Revised.

Acid-Base Balance Practice Questions Revised.A patient had 5 liters of fluid removed during a paracentesis. What intravenous (IV) solution may be used to pull fluid into the intravascular space after the paracentesis? 0.9% sodium chloride 25% albumin solution Lactated Ringer's solution 5% dextrose in 0.45% saline - ANSWERS.25% albumin solution After a paracentesis of 5 L or greater of ascites fluid, 25% albumin solution may be used as a volume expander. Normal saline, lactated Ringer's, and 5% dextrose in 0.45% saline will not be effective for this action. A nurse reviews the arterial blood gas results of a client and notes the following: pH 7.45, Pco2 of 30, and HCO3- of 22. The nurse analyzes these results as indicating which condition? 1) Metabolic Acidosis, compensated 2) Respiratory Alkalosis, compensated 3) Metabolic Alkalosis, compensated 4) Respiratory Acidosis, compensated - ANSWERS.Answer: 2 Rational: The normal pH is 7.3-7.45. In a respiratory condition, an opposite effect will be seen between the pH and the Pco2. In this condition, the pH is a the high end of normal and the Pco2 is low. In an alkalotic condition, the pH is elevated. Therefore the values identified in the question indicated a respiratory alkalosis. When the pH returns to a normal value, compensation has occurred. A nurse is caring for a client with a nasogastric tube that is attached to low suction. The nurse monitors the client, knowing that the client is at risk for which acid-base disorder? 1) Metabolic Acidosis 2) Metabolic Alkalosis 3) Respiratory Acidosis 4) Respiratory Alkalosis - ANSWERS.Answer: 2
