Of the options below, which one must be reported to the charge nurse “STAT”?

Depending on people's activity level, a normal adult’s radial pulse is 60-100 beats per minute. It is above normal when the radial pulse is 135 beats per minute and it should be addressed immediately. The respiratory rate of 18 falls in a “normal” category and cloudy urine or loose stools may be a problem but not something that necessitates the label “STAT.”
