ATI Fluid and Electrolytes

1. What is the main water-holding force in the blood capillaries?

Correct answer: C

Rationale: The correct answer is C: Protein in the blood plasma. Plasma proteins, especially albumin, create oncotic pressure, which is the main force responsible for holding water within the blood capillaries. Capillary blood pressure (Choice A) is involved in pushing blood through the capillaries, while sodium and chloride in the blood plasma (Choices B and D) are electrolytes and do not play a significant role in the water-holding force within capillaries.

2. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?

Correct answer: B

Rationale:

3. Third spacing occurs when fluid moves out of the intravascular space but not into the intracellular space. Based on this fluid shift, the nurse will expect the patient to demonstrate:

Correct answer: D

Rationale: In the scenario of third-spacing fluid shift, where fluid moves out of the intravascular space but not into the intracellular space, the patient is expected to demonstrate hypovolemia. Hypertension (Choice A) is unlikely as hypovolemia typically leads to decreased blood pressure. Bradycardia (Choice B) is not a common manifestation of hypovolemia, as the body often tries to compensate by increasing heart rate. Hypervolemia (Choice C) indicates an excess of fluid, which is the opposite of what occurs in third spacing.

4. A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?

Correct answer: C

Rationale: The correct answer is to 'Read food labels to determine sodium content.' This is important for a client at risk for mild hypernatremia because monitoring sodium intake is crucial in managing this condition. Choice A is not directly related to managing hypernatremia. Choice B focuses on pulse monitoring, which is not specific to managing sodium levels. Choice D addresses cooking methods, which can be beneficial but is not as directly related to sodium intake monitoring as reading food labels.

5. The nurse who assesses the patient's peripheral IV site and notes edema around the insertion site will document which complication related to IV therapy?

Correct answer: C

Rationale: Infiltration is the administration of non-vesicant solution or medication into the surrounding tissue. This can occur when the IV cannula dislodges or perforates the vein's wall. Infiltration is characterized by edema around the insertion site, leakage of IV fluid from the insertion site, discomfort, and coolness in the area of infiltration, and a significant decrease in the flow rate. Air emboli (Choice A) involves air entering the bloodstream. Phlebitis (Choice B) is inflammation of a vein. Fluid overload (Choice D) is an excessive volume of fluid in the circulatory system.
