Empyema.-rationale: any condition that produces fluid accumulation or sequestration of fluid with infective properties can lead to empyema, an accumulation of pus in a body cavity, especially the pleural space, as a result of bacterial infection. an infected chest tube site, lobar pneumonia, and p. carinii pneumonia can lead to fever, chills, and sweating associated with infection. however, in this case, turbid drainage indicates that empyema has developed. pneumonia typically causes a productive cough. an infected chest tube wound would cause redness and pain at the site, not turbid drainage.client needs category: physiological integrityclient needs subcategory: physiological adaptationcognitive level: analysisreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 654.
