Difficulty: MediumPhysiological Adaptation

A registered nurse is prioritizing care for a group of clients on a medical-surgical unit after receiving the shift handoff report. Which individual's clinical presentation requires the nurse's immediate intervention?

  1. A
    A client with severe chronic obstructive pulmonary disease whose arterial blood gas reveals a pH of 7.367.36, PaCO2\text{PaCO}_2 of 56 mm Hg56 \text{ mm Hg}, and HCO3−\text{HCO}_3^- of 30 mEq/L30 \text{ mEq/L}.
  2. A client admitted with acute pancreatitis who exhibits a resting heart rate of 124 beats/min124 \text{ beats/min}, a capillary refill time of 5 seconds5 \text{ seconds}, and new-onset confusion.Answer
  3. C
    A client with chronic heart failure who reports a 2 kg2 \text{ kg} weight gain over the last 48 hours48 \text{ hours} and exhibits bilateral 2+2+ pedal edema.
  4. D
    A client recovering from an open appendectomy who reports moderate surgical site discomfort when deep breathing or changing positions.

Answer

The client admitted with acute pancreatitis who exhibits a resting heart rate of 124 beats/min, a capillary refill time of 5 seconds, and new-onset confusion.
The correct answer identifies a client exhibiting classic manifestations of systemic inflammatory response and massive fluid shifts (third-spacing), which frequently complicate acute pancreatitis. A resting heart rate of 124 beats/minute, a prolonged capillary refill time of 5 seconds, and new-onset confusion are definitive signs of severely compromised tissue perfusion and decreased cerebral oxygenation. This client is in progressive hypovolemic shock and requires immediate intravenous fluid resuscitation to prevent cardiovascular collapse and multiorgan failure.

Step-by-Step Solution

1
Analyze the arterial blood gas values for the client with chronic obstructive pulmonary disease.
The pH is 7.36 (normal), indicating fully compensated respiratory acidosis, which is a stable baseline for this chronic condition.
To rule out acute respiratory failure.
2
Evaluate the clinical presentation of the client with acute pancreatitis.
Tachycardia, significantly delayed capillary refill, and confusion indicate severe fluid shifts (third-spacing) and poor systemic perfusion.
To identify subtle or rapidly progressing signs of impending cardiovascular collapse and hypovolemic shock.
3
Assess the severity of the symptoms in the clients with heart failure and postoperative appendectomy.
Weight gain and edema are subacute chronic issues; surgical site discomfort is an expected finding after an abdominal operation.
To differentiate between expected or subacute manifestations and true acute medical emergencies.
4
Apply the principles of triage and the ABCs (Airway, Breathing, Circulation) to determine the highest priority.
The client with acute pancreatitis has an acute circulation and perfusion deficit.
Life-threatening circulatory collapse must be addressed before stable chronic conditions or expected postoperative pain.
