Final answer:
The nurse should document the finding of excessive lochia drainage as 'Excessive lochia drainage, soaked a perineal pad in 1 hour'.
Step-by-step explanation:
When documenting the finding that a client who is 2 hours postpartum has saturated a perineal pad in 1 hour, the nurse can use the term 'excessive' to describe the amount of lochia drainage. The nurse should document this finding as 'Excessive lochia drainage, soaked a perineal pad in 1 hour'.
