The nurse is caring for a patient who has a temperature reading of 100.4° F (38° C) . The patient's last two temperature readings were 98.6° F (37° C) and 96.8° F (36° C) . Which action will the nurse take?

A) Wait 30 minutes and recheck the patient's temperature.
B) Assume that the patient has an infection and order blood cultures.
C) Encourage the patient to move around to increase muscular activity.
D) Be aware that temperatures this high are harmful and affect patient safety.

Waiting 30 minutes and rechecking the patient's temperature would be the most appropriate action in this case. A fever is usually not harmful if it stays below 102.2° F (39° C), and a single temperature reading does not always indicate a fever. In addition to physical signs and symptoms of infection, a fever determination is based on several temperature readings at different times of the day compared with the usual value for that person at that time. Nurses should base actions on knowledge, not on assumptions. Encouraging the patient to increase muscular activity will cause heat production to increase up to 50 times normal. The temperature has decreased and a symptom of infection would be an increase in temperature.
