ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct answer: D

Rationale:

2. An increase in capillary blood pressure would tend to:

A. increase interstitial fluid volume.
B. increase plasma volume.
C. decrease interstitial fluid volume.
D. increase plasma volume and decrease interstitial fluid volume.

Correct answer: A

Rationale: An increase in capillary blood pressure leads to a higher force pushing fluid out of the capillaries into the interstitial space, thereby increasing interstitial fluid volume. Choice B is incorrect because capillary blood pressure affects the movement of fluid into the interstitial space, not into the plasma. Choice C is incorrect as an increase in capillary blood pressure would not decrease interstitial fluid volume. Choice D is incorrect as it combines contradictory effects when capillary blood pressure increases.

3. You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?

A. Hypernatremia
B. Hypomagnesemia
C. Hypophosphatemia
D. Hypercalcemia

Correct answer: D

Rationale:

4. 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?

A. Air emboli
B. Phlebitis
C. Infiltration
D. Fluid overload

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.
