A vaccine refrigerator loses electricity during a clinic session. Which action is most appropriate first?
Correct answer: B. Keep the refrigerator closed and monitor the temperature
- A. Open the refrigerator repeatedly to check the vaccines
- B. Keep the refrigerator closed and monitor the temperature
- C. Move all vaccines into direct sunlight for warmth
- D. Discard every vaccine immediately without assessment

Keeping the refrigerator closed limits warming and helps maintain the cold chain while the temperature is monitored. Vaccines should not be exposed to sunlight or discarded automatically before their storage history and stability are assessed.
