Final answer:
The 100 rule for sepsis refers to BP less than 100 mm Hg, pulse greater than 100 beats per minute, and temperature greater than 100 degrees Fahrenheit, signaling a need for further investigation for sepsis.
Step-by-step explanation:
The 100 rule for sepsis indicates physiological parameters that could be suggestive of sepsis. These include: a) BP less than 100 mm Hg, b) pulse greater than 100 beats per minute, and c) temperature greater than 100 degrees Fahrenheit.
It is important to note that these criteria alone are not diagnostic but can be used as a guideline for when to investigate further for the presence of sepsis, which is a potentially life-threatening condition.
