Final answer:
The labs that would be most helpful to use with a physical exam to identify Hilda's fluid status are serum electrolytes and serum proteins.
Step-by-step explanation:
The labs that would be most helpful to use with a physical exam to identify Hilda's fluid status are serum electrolytes and serum proteins. Serum electrolytes, such as sodium and potassium, can help determine the balance of fluids and electrolytes in the body. Serum proteins, such as albumin, can provide information about the osmotic pressure and fluid distribution in the body.
These labs, along with a thorough physical exam, can help healthcare professionals assess Hilda's fluid status and make appropriate decisions regarding her treatment and management.
