Difficulty: EasyPhysiological Adaptation

A client with chronic kidney disease is receiving continuous intravenous fluids. The nurse evaluates the client for physiological manifestations of fluid volume overload. Which of the following assessment findings indicate that the client is experiencing this complication? Select all that apply.

  1. Bilateral crackles auscultated in the lung basesAnswer
  2. Jugular venous distension when the head of the bed is elevatedAnswer
  3. A bounding and full radial pulseAnswer
  4. D
    A narrowing pulse pressure
  5. E
    A weak and thready peripheral pulse

Answer

The findings that indicate fluid volume overload are bilateral crackles in the lung bases, jugular venous distension, and a bounding, full radial pulse.
Fluid volume overload (hypervolemia) leads to an expansion of the intravascular space and increased hydrostatic pressure. This physiological adaptation manifests clinically as a bounding and full pulse due to increased cardiac output, jugular venous distension due to elevated central venous pressure, and pulmonary crackles as excess fluid is forced into the alveolar spaces.

Step-by-Step Solution

1
Analyze the client's risk factors.
The client has chronic kidney disease and is receiving intravenous fluids, placing them at high risk for fluid volume overload.
Kidneys with decreased function cannot adequately excrete excess fluid, making intravenous fluid administration a significant risk factor.
2
Evaluate each assessment finding against the pathophysiology of fluid volume excess.
Crackles, jugular venous distension, and a bounding pulse align with increased hydrostatic pressure and expanded intravascular volume.
Excess fluid increases central venous pressure (causing jugular distension), forces fluid into the alveoli (causing crackles), and increases stroke volume (causing a bounding pulse).
3
Identify and exclude findings associated with opposing conditions.
A narrowing pulse pressure and a weak, thready pulse are excluded.
These findings are associated with decreased intravascular volume (hypovolemia) and early shock.
