Final answer:
A temperature of 100.2°F (37.9°C) is a finding that reveals the need for further evaluation in a client who gave birth 24 hours earlier.
Step-by-step explanation:
Out of the given options, the finding that reveals the need for further evaluation in a client who gave birth 24 hours earlier is a temperature of 100.2°F (37.9°C). A postpartum temperature above 100.4°F (38°C) is considered a sign of infection and requires further evaluation. Chills, scant lochia rubra, and thirst and fatigue are normal postpartum findings and do not necessarily indicate a need for further evaluation.
