Difficulty: MediumPhysiological Adaptation

A nurse is evaluating a 72-year-old client who sustained an acute anterior myocardial infarction 24 hours ago. The client has become increasingly restless and reports mild confusion. Current assessment findings include cool and pale skin, a heart rate of 118 beats/minute, and a blood pressure of 102/84 mm Hg. The client's urine output for the past hour was 15 mL. Which action should the nurse take first?

  1. Activate the rapid response team and prepare for immediate hemodynamic interventions.Answer
  2. B
    Administer a prescribed PRN anxiolytic to manage the client's severe restlessness.
  3. C
    Increase the rate of intravenous fluids to improve renal perfusion and urine output.
  4. D
    Document the findings and continue monitoring for expected physiological adaptations.

Answer

Activate the rapid response team and prepare for immediate hemodynamic interventions.
The client is exhibiting classic compensatory signs of early cardiogenic shock following an anterior myocardial infarction. The narrowed pulse pressure (18 mm Hg), tachycardia, oliguria (15 mL/hr), and peripheral vasoconstriction (cool, pale skin) indicate severe impairment of cardiac output. This is a life-threatening emergency requiring immediate activation of the rapid response team for advanced hemodynamic support, such as inotropes or mechanical assist devices.

Step-by-Step Solution

1
Analyze the client's vital signs and physical assessment data.
The client has a narrow pulse pressure (18 mm Hg), tachycardia, oliguria, cool/pale skin, and altered mental status.
Identifying trends in clinical data is necessary to determine the client's physiological stability.
2
Synthesize the findings with the client's medical history.
The recent anterior myocardial infarction puts the client at high risk for left ventricular failure.
Connecting the history of severe cardiac tissue damage to current symptoms points to a pump failure etiology.
3
Determine the underlying physiological mechanism and prioritize the response.
The findings indicate early cardiogenic shock, requiring immediate escalation of care rather than symptomatic treatment.
Cardiogenic shock is a life-threatening emergency that cannot be managed with standard nursing comfort measures or isolated symptom management.

Key Concept

Early recognition of cardiogenic shock and prioritization of life-saving interventions.
