Difficulty: HardEstablishing Priorities

The nurse is reviewing the clinical status of four clients on a nephrology and infectious disease step-down unit. Which client requires the nurse's immediate intervention?

  1. A
    A client with urosepsis who has a temperature of 102.4°F (39.1°C), a heart rate of 115 bpm, and a blood pressure of 105/85 mm Hg.
  2. B
    A client undergoing peritoneal dialysis who reports generalized abdominal pain and has cloudy effluent in the drainage bag.
  3. A client with acute kidney injury whose electrocardiogram shows tall, peaked T-waves progressing to a widened QRS complex.Answer
  4. D
    A client receiving intravenous vancomycin who exhibits a bright red rash across the face and neck with a blood pressure of 112/68 mm Hg.

Answer

The client with acute kidney injury whose electrocardiogram shows tall, peaked T-waves progressing to a widened QRS complex.
The client with an acute kidney injury and an electrocardiogram demonstrating tall, peaked T-waves progressing to a widened QRS complex is experiencing severe hyperkalemia. A widening QRS complex is a critical warning sign of impending complete heart block, ventricular fibrillation, or asystole. According to the Airway, Breathing, and Circulation (ABC) prioritization framework, this represents an immediate, life-threatening circulation emergency requiring priority intervention (e.g., intravenous calcium gluconate) to stabilize the myocardium.

Step-by-Step Solution

1
Analyze the clinical presentation of the client with acute kidney injury.
The electrocardiogram demonstrates tall, peaked T-waves progressing to a widened QRS complex.
These are classic, progressive electrocardiographic signs of severe hyperkalemia leading to a lethal arrhythmia (such as ventricular fibrillation or asystole), which requires immediate myocardial stabilization.
2
Evaluate the competing clients for life-threatening airway, breathing, or circulation (ABC) compromises.
The other clients present with early compensatory shock (urosepsis), a localized infection (peritonitis), and a rate-related medication reaction (Red Man Syndrome).
Using the ABC framework, impending cardiac arrest is the most acute and lethal circulation threat among the group.
3
Compare the urgency of all client presentations to establish the final priority.
The client with the widening QRS complex is selected as the highest priority.
Intervening for imminent cardiac arrest takes absolute precedence over treating early sepsis, peritonitis, or a non-anaphylactic infusion reaction.

Key Concept

Prioritization of critical cardiac arrhythmias over acute infectious processes and expected pharmacological reactions.
