Final answer:
The nurse should expect the HCP to order the CBC and ANA tests if SLE is suspected.
Step-by-step explanation:
The lab test that the nurse should expect the healthcare provider (HCP) to order if systemic lupus erythematosus (SLE) is suspected in the 26-year-old female client is the Complete Blood Count (CBC) and Antinuclear Antibody (ANA) tests.
SLE is an autoimmune disease, and the presence of anti-nuclear antibodies (ANAs) is a characteristic feature of SLE. The CBC can help determine if there is anemia or other abnormal blood cell counts, which can occur in SLE.
