Zorluk: ZorPhysiological Adaptation

A client with end-stage renal disease arrives at the outpatient care center stating they have missed their last two scheduled hemodialysis treatments. The practical nurse performs a focused data collection. Which findings indicate acute physiological decompensation and require immediate escalation to the registered nurse? (Select all that apply.)

  1. Crackles auscultated halfway up the posterior lung fieldsCevap
  2. Irregular heart rate of 114 beats per minute with frequent ectopic beatsCevap
  3. C
    Reports of severe, persistent itching over the arms and chest
  4. D
    Blood pressure reading of 158/92 mm Hg
  5. New-onset generalized muscle weakness and paresthesiaCevap
  6. F
    Current hemoglobin laboratory result of 9.2 g/dL

Cevap

The findings that require immediate escalation are lung crackles, an irregular tachycardic heart rate, and new-onset muscle weakness.
A client who has missed hemodialysis is at extreme risk for life-threatening fluid overload and hyperkalemia. Lung crackles indicate fluid backing up into the alveoli (pulmonary edema), which compromises breathing. An irregular, rapid heart rate suggests cardiac dysrhythmias, a dangerous complication of elevated serum potassium (circulation). New-onset muscle weakness and paresthesia are also classic neuromuscular signs of severe hyperkalemia that precede cardiac arrest. All three of these findings reflect acute physiological decompensation requiring immediate emergency intervention.

Adım Adım Çözüm

1
Identify the client's condition and associated physiological risks.
The client has end-stage renal disease and missed hemodialysis, placing them at severe risk for life-threatening fluid retention and electrolyte imbalances, particularly hyperkalemia.
Understanding the pathophysiology of missed dialysis guides the nurse to anticipate specific acute complications.
2
Evaluate each assessment finding using the Airway, Breathing, Circulation (ABC) prioritization framework.
Lung crackles compromise breathing; an irregular heart rate compromises circulation; muscle weakness indicates imminent cardiac compromise from hyperkalemia.
The ABC framework is the standard for prioritizing physiological emergencies over chronic or stable symptoms.
3
Differentiate between acute, life-threatening symptoms and expected, chronic manifestations of the disease.
Pruritus, baseline hypertension, and chronic anemia are expected findings, whereas pulmonary edema and hyperkalemia symptoms indicate acute decompensation.
Escalation must be reserved for acute changes that threaten the client's immediate stability.
