A patient with weeks of very poor intake is about to start nutrition support. Phosphate, potassium, and magnesium have not been checked, and no thiamin has been given. Which sequence is safest?
Correct: (d) Give thiamin and check phosphate, potassium, and magnesium before a cautious calorie advance Refeeding moves phosphate, potassium, and magnesium into cells as insulin rises, and carbohydrate use depends on thiamin. Thiamin is given, and those three electrolytes are checked and repleted, before calories are advanced aggressively. Starting with a high dextrose load and adding thiamin or electrolytes later reverses the prevention order.
A malnutrition screen is positive for 95 of 100 patients who are malnourished and positive for 80 of 100 patients who are not. Which statement about the screen is correct?
Correct: (b) Sensitivity is high, because most malnourished patients test positive Sensitivity is the proportion of people who have the condition and test positive: here 95 of 100, so sensitivity is high. Specificity is the proportion who do not have the condition and test negative: here that is 20 of 100, so specificity is low. Positive predictive value also depends on prevalence and false positives, and it is not the same number as sensitivity. Reliability is about repeatability, not detection of true cases.
A tray aide sprains an ankle while pushing a cart on the unit. Which benefit is designed to pay medical care and part of the lost wages for that work injury?
Correct: (a) Workers' compensation carried by the employer for job-related injury Workers' compensation is the employer's no-fault coverage for medical care and a portion of lost wages when an employee is injured on the job. A sprain while pushing a work cart is the type of injury that program addresses.

RD Exam study guide
What is inside
240 MCQ cards aligned to the CDR Registration Examination for Dietitians domains: Principles of Dietetics (50 cards, 21%), Nutrition Care for Individuals and Groups (108 cards, 45%), Management of Food and Nutrition Programs and Services (50 cards, 21%), and Foodservice Systems (32 cards, 13%). Every card includes a correct explanation and notes on why the other options fail. The free timed check draws 120 of these 240 items on each attempt.
2–3 week study plan with the free mock
**Week 1:** 15–20 new cards/day across principles and nutrition care (PES / ADIME, macros, MNT themes). **Week 2:** Add foodservice and management cards; sit the [120-question RD readiness check (free 25-question version)](/mock-exams/rd-exam-readiness-check). **Final days:** Review-only Anki on weak topics from the report — keep official CDR handbook timing practice separate (3-hour adaptive exam, scaled pass 25/50).
Pitfalls this deck targets
Candidates over-focus on clinical MNT and under-drill foodservice sanitation, procurement, and management finance. Cards force all four CDR domains under spaced recall, not just favorite clinical topics. This is not a recycled nursing or personal-trainer bank.
What this does not replace
ACEND education, supervised practice, and the official CDR / Pearson VUE exam. This deck is independent prep — not CDR material.
