The nurse is making a follow-up telephone call to a 52-year-old client with lung cancer. The client now has a low-grade fever 100.6, nonproductive cough, and increasing fatigue. The client completed the radiation therapy to the mass in the right lung and mediastinum 10 weeks ago and has a follow-up appointment to see the healthcare provider in 2 weeks. The nurse should advise the client:
A. To take two acetaminophen tablets every 4 to 6 hours for 2 days and call the healthcare provider if the temperature increases to 101 or greater
B. That this is an expected side effect of the radiation therapy and to keep his appointment in 2 weeks
C. To contact the healthcare provider for an appointment today
D. To go to the nearest emergency department
