When you assess Mr. Stevens at 4
P.M., you find his urine output is 40
mL. When you return at 7 P.M. to
check his vital signs and urine out-
put, his BP is still a bit low (92/45
mm Hg), but otherwise he seems to
be doing well; his urine output
this hour is 82 mL. On your fi-
nal check at 10 P.M., his output
is 95 mL
