ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

Correct answer: B

Rationale:

2. What is the main force that pushes fluid in blood capillaries?

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.

3. A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?

Correct answer: B

Rationale:

4. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

Correct answer: D

Rationale: Third spacing refers to the loss of fluid from the intravascular space into the interstitial or third space, leading to a decrease in circulating blood volume. This condition results in hypovolemia, which is characterized by decreased blood volume. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly associated with third spacing. Metabolic alkalosis is an acid-base imbalance, hypermagnesemia is an excess of magnesium in the blood, and hypercalcemia is an excess of calcium in the blood, none of which are the primary concerns in cases of third spacing.

5. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

Correct answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.
