A nurse is assigned to a client recently admitted because of unexplained weight loss, insomnia, and fullness in the throat. The attending physician, several medical students, and a physician’s assistant subsequently palpate this enlargement. Later, the client becomes restless and disoriented. The heart rate increases to 165 beats per minute, respirations are rapid, and the temperature is recorded at 103.8F (39.8C). What is a possible explanation for the changes in the client’s condition and what methods would be used to manage them?
