3.5. Encourage adequate fluid intake (2000 mL per 24 hours), increased fiber in diet; regular exercise.
3.6. Monitor I&O and specific gravity; include all output sources.
3.7. Assess skin turgor and moisture of mucous membranes. Note reports of thirst.
3.8. Assess skin frequently for side effects of cancer therapy; note breakdown and delayed wound healing. Emphasize importance of reporting open areas to caregiver.

4.1. Initial testing
4.1.1. CBC - check for amenia
4.1.2. Liver function - CRC may spread to the liver
4.1.3. Colonoscopy
4.1.4. CT colography - if colonoscopy is incomplete
4.2. Diagnostic procedures
4.2.1. Biopsy - performed during colonoscopy
4.2.2. CT needle guided biopsy - to evaluate suspected tumors or metastasis.
