CNS study plan

CNS · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Food and Nutrition Science Knowledge

  • Map the digestion, absorption, and transport pathways for carbohydrate, protein, and lipid into a single annotated flow diagram

  • Calculate estimated energy needs (Mifflin-St Jeor plus activity and stress factors) for 10 adult profiles and compare results with indirect-calorimetry values

  • Explain the metabolic roles of the fat-soluble and water-soluble vitamins and list two classic deficiency presentations for each

  • Summarize fluid and electrolyte balance regulation (renin-angiotensin-aldosterone, ADH, thirst) in 15 bullet points

Your checkpoint

A one-page-per-topic summary set (6 pages) plus a 40-question self-quiz scored at 80% or higher, with missed items re-taught in writing

Week 2

Food and Nutrition Science Knowledge & Nutrition Assessment

  • Compare nutrient requirements across the life cycle (pregnancy, lactation, infancy, childhood, adolescence, older adulthood) in a matrix format

  • Perform and record anthropometric measurements on 3 volunteers and calculate BMI, waist circumference risk, and percent weight change

  • Interpret 20 sets of laboratory values (albumin, prealbumin, transferrin, CRP, CBC, electrolytes, glucose, lipids, renal and liver panels) against reference ranges

  • Select the appropriate nutrition screening tool for a given care setting and justify the choice in two sentences

Your checkpoint

A completed laboratory interpretation worksheet for 20 cases with a written interpretation and a stated nutrition implication for each

Week 3

Nutrition Assessment & Nutrition Diagnosis

  • Conduct a full nutrition-focused physical exam sequence (head, neck, oral cavity, skin, hair, nails, extremities, muscle and fat stores) and document findings using standardized terminology

  • Collect and analyze a 24-hour recall and a food frequency questionnaire, then compute intake adequacy for energy, protein, and 5 micronutrients

  • Write problem-etiology-signs-and-symptoms (PES) statements that link each identified problem to a documented etiology and to objective evidence

  • Differentiate among intake, clinical, behavioral-environmental, and knowledge-belief domains when assigning a diagnosis and select the correct standardized term

Your checkpoint

15 PES statements built from written case vignettes, each scored against a self-made rubric for specificity, etiology linkage, and evidence support

Week 4

Nutrition Intervention & Nutrition Monitoring and Evaluation

  • Design medical nutrition therapy plans for 4 conditions (type 2 diabetes, chronic kidney disease, heart failure, and post-surgical malnutrition) stating the specific nutrition prescription

  • Compare enteral and parenteral routes by calculating formula volume, osmolality considerations, and advancement schedules for 3 sample patients

  • Select monitoring and evaluation indicators and set measurable target dates for each intervention goal

  • Determine when to revise versus terminate a nutrition intervention based on documented progress data

Your checkpoint

Two complete Nutrition Care Process records (assessment, diagnosis, intervention, monitoring and evaluation) from intake through planned follow-up, reviewed against a 20-point checklist

Week 5

Nutrition Intervention & Counseling and Communication

  • Apply at least 6 specific behavior-change constructs (self-efficacy, stages of change, decisional balance, stimulus control, relapse prevention, social support) to realistic client scenarios

  • Demonstrate the core skills of motivational interviewing (open questions, affirmations, reflections, summaries, eliciting change talk) in a simulated session

  • Adapt education materials and teaching approach for low health literacy, limited English proficiency, and older adult audiences

  • Write 5 SMART nutrition goals jointly with a simulated client and verify each is measurable and client-owned

Your checkpoint

A recorded 10-minute mock counseling session with a completed self-evaluation checklist (reflection-to-question ratio, change talk count, and 2 identified improvement targets)

Week 6

Counseling and Communication & Research and Evidence-Based Practice

  • Explain study designs (RCT, cohort, case-control, cross-sectional, systematic review) and rank their evidentiary strength with justification

  • Interpret p-values, confidence intervals, relative risk, odds ratio, and number needed to treat in 10 published abstract excerpts

  • Apply a structured critical appraisal tool to evaluate bias, confounding, and applicability to a specific patient population

  • Deliver a 5-minute plain-language research summary to a non-clinical audience without overstating findings

Your checkpoint

Three completed critical appraisal worksheets on nutrition intervention studies plus a one-paragraph practice recommendation for each

Week 7

Research and Evidence-Based Practice & Professional Practice, Ethics, and Business

  • Translate evidence into a practice protocol for one clinical question using a documented search strategy and inclusion criteria

  • Resolve 12 ethics scenarios involving scope of practice, informed consent, conflicts of interest, confidentiality, and cultural humility with cited rationale

  • Outline the business fundamentals of a nutrition practice: reimbursement pathways, coding, documentation requirements, and pricing a service

  • Identify the credential maintenance, continuing education, and professional standards obligations that govern practice

Your checkpoint

A 10-page practice portfolio containing one evidence-to-protocol brief, 12 resolved ethics vignettes with rationale, and a one-page business/reimbursement summary

Week 8

Food and Nutrition Science Knowledge & Nutrition Assessment & Nutrition Diagnosis & Nutrition Intervention & Nutrition Monitoring and Evaluation & Counseling and Communication & Research and Evidence-Based Practice & Professional Practice, Ethics, and Business

  • Complete two timed full-length mock examinations under test-day conditions and record domain-level performance

  • Categorize every missed item by root cause (content gap, misread question, calculation error, unfamiliar term) and re-study the top 3 gap areas

  • Recite from memory the Nutrition Care Process chain and the standardized terminology domains without prompts

  • Build a one-page high-yield reference sheet covering formulas, lab cutoffs, and screening thresholds for final review

Your checkpoint

A scored full-length mock exam with a written error log and a remediation list, achieving 80% or higher overall and 70% or higher in every domain

Milestones

Week 2: Score 80% or higher on a 30-question Domain 1 and 2 mixed quiz, and correctly interpret all 20 laboratory cases without referencing the answer key

Week 4: Produce 15 rubric-passing PES statements and 2 complete Nutrition Care Process records with no missing elements

Week 6: Complete all 3 critical appraisal worksheets with defensible bias ratings and a clear applicability statement

Week 8: Attain 80% or higher on the full-length mock exam with no domain below 70% and a documented error log with remediation plan
