Zorluk: OrtaReduction of Risk Potential

A nurse is evaluating a 6868-year-old client who underwent a left-sided thoracentesis 22 hours ago for the treatment of a large pleural effusion secondary to heart failure. Which of the following assessment findings indicate a potential life-threatening complication and require immediate intervention? Select all that apply.

  1. Asymmetrical chest wall expansion with diminished breath sounds on the left sideCevap
  2. A narrowing pulse pressure accompanied by a steady increase in resting heart rateCevap
  3. C
    Arterial blood gas results showing a pH of 7.387.38, PaCO 2_2 of 4141 mm Hg, and PaO 2_2 of 8989 mm Hg on room air
  4. D
    Client report of localized pain rating a 33 on a 00 to 1010 scale at the posterior puncture site
  5. Sudden development of a severe, continuous cough producing pink, frothy sputumCevap

Cevap

The correct findings that indicate life-threatening complications are asymmetrical chest wall expansion with diminished breath sounds, a narrowing pulse pressure with an increasing heart rate, and a severe cough producing pink, frothy sputum.
A thoracentesis carries risks of severe physiological complications, primarily pneumothorax, hemothorax leading to hypovolemic shock, and re-expansion pulmonary edema. Asymmetrical chest expansion and diminished breath sounds on the affected side are classic indicators of a pneumothorax, which can rapidly progress to a tension pneumothorax. A narrowing pulse pressure combined with a steadily increasing resting heart rate represents the body's compensatory mechanism during early hypovolemic or hemorrhagic shock. Finally, the sudden development of a severe, continuous cough producing pink, frothy sputum is the hallmark sign of re-expansion pulmonary edema, a medical emergency that can occur when a large volume of fluid is rapidly drained from the pleural space. All three of these findings indicate impending physiological decompensation and demand immediate intervention.

Adım Adım Çözüm

1
Identify the procedure performed and its associated high-risk complications.
The client had a thoracentesis. Major complications include pneumothorax, hemothorax, hypovolemic shock, and re-expansion pulmonary edema.
Recognizing procedure-specific risks is essential for targeted post-operative assessment.
2
Evaluate each assessment finding against the known complications.
Asymmetrical chest expansion and decreased breath sounds indicate pneumothorax. Narrowing pulse pressure and tachycardia suggest early shock. Pink, frothy sputum with a severe cough indicates re-expansion pulmonary edema.
Matching clinical signs to pathophysiology determines which findings are life-threatening.
3
Differentiate expected post-procedure findings from abnormal ones.
Normal ABG values and mild, localized pain at the puncture site are expected or non-emergent findings that do not require immediate life-saving intervention.
Prioritization requires distinguishing between stable/expected outcomes and physiological decompensation.

Early recognition of thoracentesis complications (pneumothorax, shock, pulmonary edema) is critical for reducing the risk of physiological decompensation.
