A 4-year-old boy has a measured 39.6°C, with a previous reading of 36.3°C two hours earlier. He reports no fever and feels well. What is the appropriate nursing action?

• A. Take the temperature again in another hour.
• B. Use a different thermometer to retake the temperature.
• C. Take a rectal temperature to obtain a core temperature.
• D. Administer the ordered antipyretic.

Answer: (B)

Verifying temperature accuracy is the first priority when a reading doesn’t fit how the child is acting. A 4-year-old who feels well but shows a very high temperature suggests the measurement may be wrong rather than a sudden fever rise. Using a different thermometer helps determine if the problem lies with the instrument, probe placement, or technique, rather than with the child’s condition. If the alternate reading confirms fever, you’d then assess further and treat as needed. If it does not, you’ve avoided unnecessary interventions based on an erroneous value. Rectal temperature and antipyretic administration aren’t warranted until the measurement is confirmed and the clinical picture supports fever.
