Sit 12 original exam-style questions at real exam pace
These are 12 original questions taken from our Clinical Dietitian bank, spread across 7 of the 8 domains of the published blueprint. You get 72 seconds per question, which is exactly the pace of the real NUT4112 exam (14 minutes for 12). At the end you will see which domains you are weakest in, and the full worked reasoning for every question.

A short diagnostic cannot predict whether you will pass - only the real exam does that. It will show you, honestly, where you currently stand.
What the real Clinical Dietitian licensing exam looks like
Candidates for a Clinical Dietitian licence in the UAE sit a computer-based multiple-choice examination - DHA exam code NUT4112, delivered through Prometric for DHA, MOHAP and SHA, and through Pearson VUE for DOH Abu Dhabi. The DHA pass mark is 55% (DHA CBT Guideline, Sep 2026); other authorities set their own, so confirm yours before booking. The result is reported to you as pass or fail only - your score is never released.
Pass marks at a glance: DHA exam codes and pass marks for all written exams in one sourced table.
The paper is built to a published blueprint, which is why a domain-by-domain diagnostic is more useful than a raw percentage. Your questions above were drawn from across Enteral and Parenteral Nutrition, Counselling, Public Health Nutrition and Ethics, Medical Nutrition Therapy: Diabetes, Cardiometabolic and Obesity, Medical Nutrition Therapy: Renal, Hepatic and Gastrointestinal and 3 more - the same areas the real paper weights.
Before you can book the exam at all you need Dataflow primary source verification of your degree, licence and experience, which typically runs several weeks. Candidates routinely underestimate this and end up sitting the exam sooner after study than they planned. Check where you stand with our free eligibility checker or confirm whether your title even requires an exam using the Prometric exam checker.
You get three attempts in total across all UAE authorities - not three each - under the Unified Professional Qualification Requirements. At roughly AED 880 per attempt, plus the licensing delay each failure adds to your visa and start date, the cost of going in underprepared is not really the exam fee.

A worked Clinical Dietitian exam question
Every question in the diagnostic and in the paid bank is written to this standard: a clinical stem, four plausible options and the reasoning for the answer, with its source.
Enteral and Parenteral Nutrition
A ventilated patient is receiving nasogastric feeding. Which measure most reduces the risk of aspiration?
- AStop feeds for any gastric residual
- BKeep the patient flat during feeds
- CGive feeds as rapid large boluses
- DRaise the head of bed to 30 to 45 degreesCorrect
Why: Elevating the head of the bed to 30 to 45 degrees reduces reflux and aspiration in enterally fed patients. Lying flat and rapid boluses increase risk, and stopping feeds for small residuals reduces delivery without clear benefit.

Clinical Dietitian sample questions with answers
4 more original exam-style Clinical Dietitian questions, worked in full. They are not real or recalled exam questions, and none of them is in the diagnostic above, so sit that first if you have not.
Question 1 · Counselling, Public Health Nutrition and Ethics
A population survey finds widespread goitre and low urinary iodine. Which public health intervention is recommended as the main strategy?
- AAdvising people to eat less salt
- BFortifying bread with folic acid
- CIodine tablets for older men only
- DUniversal salt iodisation
Show answer and explanation
Correct answer: D. Universal salt iodisation
Universal salt iodisation is the WHO-recommended, cost-effective strategy to prevent iodine deficiency disorders. Salt reduction and iodisation are compatible, as iodine concentration can be adjusted.

Question 2 · Food Service Management and Food Safety
A large batch of cooked rice will be chilled for later service. Which cooling standard should the kitchen follow?
- A57 to 5 C over 12 h at room temperature
- B57 to 21 C in 2 h, then to 5 C within 4 h
- CLeave at room temperature until service
- DCool to 21 C within 8 h, then refrigerate
Show answer and explanation
Correct answer: B. 57 to 21 C in 2 h, then to 5 C within 4 h
The Food Code requires cooling from 57 to 21 degrees Celsius within 2 hours and to 5 degrees or less within a further 4 hours. Slow cooling of rice allows Bacillus cereus spores to germinate and produce toxin.

Question 3 · Life Cycle and Paediatric Nutrition
A woman of healthy weight is in her third trimester of a singleton pregnancy. Approximately how much additional energy per day is estimated above her non-pregnant needs?
- AAbout 800 kcal
- BAbout 100 kcal
- CAbout 450 kcal
- DNo additional energy
Show answer and explanation
Correct answer: C. About 450 kcal
The Institute of Medicine estimates no extra energy in the first trimester, about 340 kcal in the second and about 450 kcal in the third trimester. Doubling intake is not needed.
Reference: Institute of Medicine Dietary Reference Intakes for Energy 2005
Question 4 · Food Service Management and Food Safety
In a hospital kitchen HACCP plan, cooking chicken is a critical control point. Which minimum internal temperature is the critical limit?
- A50 degrees Celsius (122 F)
- B63 degrees Celsius (145 F)
- C57 degrees Celsius (135 F)
- D74 degrees Celsius (165 F)
Show answer and explanation
Correct answer: D. 74 degrees Celsius (165 F)
Poultry must reach an internal temperature of at least 74 degrees Celsius for an instant to destroy Salmonella and Campylobacter. 63 degrees Celsius applies to whole cuts of beef or fish.

How to use this diagnostic properly
- 1Sit it cold, once. Do not look anything up. A diagnostic you help yourself through tells you nothing. The number you get is only useful if it is honest.
- 2Read every rationale - especially the ones you got right. Getting a question right by elimination is not the same as knowing it. The worked reasoning is free above, whether or not you buy anything.
- 3Work weakest domain first. The breakdown orders your domains worst-first for exactly this reason. Studying what you are already good at feels productive and moves nothing.
- 4Re-sit under full exam conditions later. The real paper is far longer than this and stamina matters. Full-length timed papers are what the paid bank is for.
