The nurse is providing care for a patient with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia. The patient is receiving aerosolized pentamidine isethionate. What is the best evidence that the therapy is working?
A) A sudden gain in lost body weight
B) Whitening of lung fields on the chest x-ray
C) Improved patient vitality and activity tolerance
D) A febrile body temperature and development of leukocytosis
Ans: C
Feedback: P. carinii pneumonia is a protozoal infection of the lungs. Pentamidine isethionate is one drug used to treat this infection. Because a common manifestation of the infection is activity intolerance and loss of vitality, improvements in these areas suggest success of the therapy. Sudden weight gain, whitening of the lung fields on the chest x-ray, and development of leukocytosis aren't evidence of therapeutic success.
