These include: Hospital lifetime reserve days: Medicare Part A covers a stay in the hospital for any single spell of illness or injury within a time frame of 90 days. This is known as a benefit period, and thereâs no limit to the number of benefit periods you can have. But if you need to stay in the hospital for more than 90 days with the same illness or injury, you have the option of using some of your 60 lifetime reserve days.
Pain measures fall into 2 categories: 1  Single-dimensional scales - These scales assess a single dimension of pain and, through patient self-reporting, measure only pain intensity; these scales are useful in acute pain when the etiology is clear; see the image below Faces Pain Rating Scale.
The most famous magnitude scale is the Richter scale which is used to determine the magnitudes of intermediate strength earthquakes. For larger earthquakes (those greater than 7.0) the Moment Magnitude scale is used. In the US the most commonly used intensity scale is the Modified Mercalli scale.
