Difficulty: Very hardReduction of Risk Potential

A nurse is caring for a client with decompensated liver cirrhosis who has just undergone a therapeutic paracentesis with the removal of 6.56.5 liters of ascitic fluid. Thirty minutes after the procedure, the client reports feeling lightheaded. The puncture site dressing is dry and intact.

Blood Pressure126/74126/74 mmHg104/82104/82 mmHg
Heart Rate8484 bpm114114 bpm
Respiratory Rate1818 breaths/min2626 breaths/min

Current arterial blood gas (ABG) on room air:

PaO 2_2: 8888 mmHg
HCO 3−_3^-: 2323 mEq/L

Which of the following is the priority nursing action to reduce the client's risk of a severe physiological complication?

  1. A
    Place the client in a high Fowler's position to optimize diaphragmatic excursion.
  2. B
    Administer a prescribed PRN intravenous beta-blocker to manage the new-onset tachycardia.
  3. Initiate the prescribed intravenous albumin infusion.Answer
  4. D
    Encourage slow, deep breathing exercises to correct the uncompensated respiratory alkalosis.

Answer

The correct action is to initiate the prescribed intravenous albumin infusion.
The correct answer is to initiate the prescribed intravenous albumin infusion. The client is exhibiting classic signs of Post-Paracentesis Circulatory Dysfunction (PPCD), a form of hypovolemic shock caused by rapid fluid shifts and splanchnic vasodilation after the removal of large volumes of ascitic fluid. The profoundly narrowing pulse pressure (dropping from 5252 mmHg to 2222 mmHg), tachycardia, tachypnea, and lightheadedness are early compensatory mechanisms for cardiovascular collapse. Albumin acts as a powerful colloid volume expander, increasing intravascular oncotic pressure to pull fluid back into the vascular space and mitigate this life-threatening fluid shift.

Step-by-Step Solution

1
Analyze the client's vital sign trends and current clinical presentation.
The client has a significantly narrowing pulse pressure (dropping from 5252 mmHg to 2222 mmHg), new-onset tachycardia (114114 bpm), and tachypnea (2626 breaths/min) accompanied by lightheadedness.
These are hallmark compensatory signs of early distributive/hypovolemic shock.
2
Correlate the clinical findings with the recent procedure.
The client had 6.56.5 liters of fluid removed during paracentesis, placing them at high risk for Post-Paracentesis Circulatory Dysfunction (PPCD).
Rapid removal of large volumes of ascites (typically >5> 5 liters) causes profound splanchnic vasodilation and fluid shifts out of the intravascular space into the peritoneal cavity.
3
Evaluate the arterial blood gas (ABG) results in the context of the clinical picture.
The ABG indicates uncompensated respiratory alkalosis, which is a sympathetic and compensatory response to shock and hypoxia at the tissue level, rather than a primary respiratory disorder.
Treating the ABG abnormality in isolation would dangerously ignore the underlying life-threatening hemodynamic instability.
4
Determine the absolute priority nursing intervention for risk reduction.
The nurse must immediately initiate the prescribed intravenous albumin infusion.
Albumin is a colloid that increases intravascular oncotic pressure, pulling fluid back into the vascular space and preventing the progression of PPCD to severe cardiovascular collapse.
