American Board of Ophthalmology (ABO) Practice Exam

Using a finger to check the temperature of a salt pan can provide immediate tactile feedback, making it a quick and simple method for obtaining a rough estimate of the surface temperature. When you touch the pan, you can gauge whether it feels hot, warm, or cool. This method doesn't require any special tools or equipment and can be performed rapidly, which is advantageous in situations where you need an immediate assessment. While other options such as a digital thermometer, infrared sensor, or temperature strip can provide more precise measurements, they may not deliver the same speed of assessment when an immediate feel is needed. Additionally, these methods often require additional setup, calibration, or consideration of how to use them effectively, which may not be practical in scenarios that demand a quick check.
