CNSC study guide
CNSC · Work through your exam, one topic at a time.
The Certified Nutrition Support Clinician (CNSC) credential is awarded by the National Board of Nutrition Support Certification (NBNSC) to clinicians who demonstrate specialized knowledge in nutrition support. It is aimed at practitioners - dietitians, nurses, pharmacists, and physicians - whose work involves specialized nutrition support, and it signals that expertise to employers and colleagues. NBNSC notes that employers can verify a CNSC credential using the certification number and the holder's current state. The Certification Examination for Nutrition Support Clinicians is a computer-based exam composed of a maximum of 250 multiple-choice, objective questions, with a total allowed testing time of four hours. The CNSC study guide has 4 sections and about 1,491 words.
01Nutrition Assessment
Nutrition Assessment is the first CNSC domain and tests whether you can build a defensible nutrition diagnosis from intake, anthropometrics, biochemical data, physical findings, and functional status-not from a single laboratory value. The AND/ASPEN adult malnutrition criteria require at least two of: insufficient energy intake, weight loss, loss of muscle mass, loss of subcutaneous fat, localized or generalized fluid accumulation, and diminished functional status.
