Prometric Exam Questions for Dietitians and Nutritionists 2026: 15 Practice MCQs with Answers and Rationale for the NUT4112 and NUT4111 Papers

The clinical dietitian paper (NUT4112) and the nutritionist paper (NUT4111) test whether you can assess a patient, calculate what they need, prescribe the right diet or feed and spot the danger signs. Diabetes, obesity and kidney disease are among the most common conditions in the Gulf, which is why dietitians are hired steadily and why the exam leans on them. Both papers are usually 100 to 150 single-best-answer questions in 2 to 3 hours, with pass marks around 50 to 55%.

The fifteen questions below follow the blueprint. Allow about 70 seconds each and read every rationale. Calculations and refeeding are reliable marks.

For titles, eligibility and the syllabus, read the dietitian and nutritionist guide. For timed papers use the Clinical Dietitian bank or the Nutritionist bank.

Assessment and requirements

Question 1

A woman is 160 cm tall and weighs 80 kg. Her BMI and WHO classification are:

1. 25, overweight
2. 31.3, obese class I
3. 28, overweight
4. 35, obese class II

Answer: B. BMI is 80 divided by 1.6 squared (2.56), which is 31.25. Class I obesity is 30 to 34.9. Many Gulf programmes apply lower cut-offs for Asian populations; know both.

Question 2

Estimated protein requirement for a 70 kg patient in a critical care unit with sepsis is approximately:

1. 0.5 g/kg/day, about 35 g
2. 1.2 to 2.0 g/kg/day, about 85 to 140 g
3. 3.5 g/kg/day
4. Protein is not required in sepsis

Answer: B. Critical illness raises protein needs to 1.2 to 2.0 g/kg/day, delivered progressively, while energy is often targeted at about 20 to 25 kcal/kg/day in the acute phase.

Question 3

Which measurement is the most practical indicator of recent nutritional change in a hospital inpatient?

1. Serum albumin alone
2. Percentage unintentional weight loss over the previous three to six months, combined with intake and BMI in a validated screening tool such as MUST
3. Hair analysis
4. Serum sodium

Answer: B. Albumin falls with inflammation and fluid shifts and is a poor marker of nutrition. Weight loss of more than 5 to 10% is clinically significant and drives screening scores.

Diabetes, renal and liver nutrition

Question 4

A patient with type 2 diabetes and a BMI of 33 asks for the most effective dietary approach to improve glycaemic control. The evidence-based advice is:

1. A very high-protein diet with no carbohydrate for life
2. An individualised energy-reduced pattern (for example Mediterranean, lower-carbohydrate or portion-controlled) that achieves sustained weight loss of 5% or more, with consistent carbohydrate distribution
3. Fruit juice as the main carbohydrate
4. Skipping breakfast

Answer: B. No single pattern is mandated; sustained weight loss and consistent, quality carbohydrate intake improve HbA1c. Juices and sugary drinks are replaced, and meal timing is matched to medication.

Question 5

A patient on maintenance haemodialysis has a pre-dialysis potassium of 6.2 mmol/L and phosphate of 2.1 mmol/L. Dietary advice includes:

1. Increase bananas, oranges and dairy
2. Limit high-potassium foods and use leaching techniques for vegetables, limit high-phosphate foods and additives, take phosphate binders with meals, and keep protein at about 1.0 to 1.2 g/kg/day
3. Stop all protein
4. Unrestricted fluid

Answer: B. Dialysis patients need adequate protein to offset losses, with controlled potassium, phosphate, sodium and fluid. Phosphate additives in processed foods are often the hidden source.

Question 6

A patient with cirrhosis and mild hepatic encephalopathy should be advised to:

1. Restrict protein to under 0.5 g/kg/day
2. Maintain protein at about 1.2 to 1.5 g/kg/day in small frequent meals with a late-evening carbohydrate snack, favouring plant and dairy protein
3. Fast overnight for 14 hours
4. Eat one large meal a day

Answer: B. Protein restriction worsens sarcopenia and outcomes in cirrhosis. Frequent meals and a bedtime snack reduce overnight catabolism; lactulose and rifaximin manage encephalopathy.

Enteral and parenteral nutrition

Question 7

A severely malnourished patient (BMI 15, minimal intake for 10 days) is to start feeding. The safest approach is:

1. Full-rate feeding from day one
2. Start at about 5 to 10 kcal/kg/day, give thiamine before feeding, check and replace phosphate, potassium and magnesium daily, and increase to target over 4 to 7 days
3. Parenteral nutrition at full rate immediately
4. Intravenous glucose alone

Answer: B. This is high refeeding risk. The hallmark of refeeding syndrome is a sharp fall in phosphate with cardiac and respiratory compromise; slow introduction, thiamine and electrolyte monitoring prevent it.

Question 8

Which statement about nasogastric feeding is correct?

1. Tube position is confirmed by auscultation of injected air
2. Position is confirmed by aspirate pH of 5.5 or below, or by x-ray when aspirate cannot be obtained, before every feed and after any sign of displacement
3. The patient should lie flat during feeding
4. Feeds never need to be paused

Answer: B. Auscultation is unreliable and has caused deaths from feeding into the lung. The head of the bed is kept at 30 to 45 degrees during and after feeding to reduce aspiration.

Question 9

Parenteral nutrition rather than enteral feeding is indicated when:

1. The patient dislikes the taste of supplements
2. The gut is non-functional or inaccessible, for example high-output fistula, prolonged ileus or short bowel, and enteral feeding cannot meet needs
3. The patient has mild dysphagia
4. The patient is on a ventilator

Answer: B. "If the gut works, use it." Enteral feeding maintains gut integrity and has fewer infective and metabolic complications; PN is reserved for intestinal failure and needs central access, line care and daily biochemistry.

Life stages

Question 10

A pregnant woman asks which supplement is recommended before conception and through the first trimester to reduce neural tube defects:

1. Vitamin A 10,000 IU daily
2. Folic acid 400 micrograms daily, increased to 4 to 5 mg for women at high risk
3. Iron 200 mg three times a day for everyone
4. No supplements are needed

Answer: B. Folic acid is started before conception. High-dose vitamin A is teratogenic and liver products are limited; vitamin D is advised throughout pregnancy, and iron is given where deficient.

Question 11

Exclusive breastfeeding is recommended for the first:

1. 6 weeks
2. 6 months, with complementary foods introduced from around 6 months while breastfeeding continues
3. 3 months
4. 12 months with no solids

Answer: B. WHO and Gulf national guidance recommend exclusive breastfeeding to six months, with iron-rich complementary foods from around six months and continued breastfeeding to two years or beyond.

Question 12

Which vitamin deficiency is most prevalent in the Gulf population and is routinely screened for and supplemented?

1. Vitamin C
2. Vitamin D
3. Vitamin K
4. Vitamin B7

Answer: B. Vitamin D deficiency is extremely common across the Gulf because of limited sun exposure, clothing and indoor living; supplementation and dietary advice are routine in antenatal, paediatric and bone health clinics.

Food safety and counselling

Question 13

The temperature danger zone in which bacteria multiply rapidly in food is approximately:

1. 0 to 4 °C
2. 5 to 60 °C
3. 70 to 100 °C
4. Below freezing

Answer: B. Keep cold food at or below 4 to 5 °C and hot food at or above 60 to 63 °C; cooked food should not sit in the danger zone for more than two hours, less in Gulf heat.

Question 14

A patient with coeliac disease must avoid which of the following?

1. Rice and maize
2. Wheat, barley and rye, including hidden sources such as sauces, soups and some processed meats
3. Potatoes
4. All dairy for life

Answer: B. A strict lifelong gluten-free diet is the only treatment. Oats are tolerated by most if certified uncontaminated. Temporary lactose intolerance may occur at diagnosis but resolves as the mucosa heals.

Question 15

Which counselling approach is most effective for sustained dietary change in an adult with obesity?

1. Handing over a printed diet sheet without discussion
2. Motivational interviewing with collaborative, specific and measurable goals, self-monitoring and regular follow-up
3. Threatening the patient with complications
4. Advising a 500 kcal/day crash diet indefinitely

Answer: B. Behaviour change techniques, not information alone, drive adherence. Very low energy diets are used only in supervised programmes for defined periods.

How to use these questions

• Drill calculations: BMI, energy and protein requirements, feed rates and percentages.
• Learn the disease diets by numbers: renal potassium and phosphate, cirrhosis protein, diabetes carbohydrate distribution.
• Know refeeding and tube safety as sequences; they are asked on every paper.
• Practise under time in the Clinical Dietitian bank or Nutritionist bank, using the error-log method.

Other allied health banks are listed in allied health question banks. When you hold eligibility, join the dietitian talent pool; hospitals, bariatric centres and diabetes clinics across the Gulf recruit continuously.
