Practice questions
01 Why are snacks and beverages asked about in a patient's diet history?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. To assess hidden sugar, fat, salt and extra energy
Explanation: Snacks and beverages are important parts of total dietary intake, even when people do not consider them to be meals. Sweetened drinks may add sugar and energy, while packaged snacks may provide excess sodium and fat with little fibre or micronutrient value. Asking about them makes the diet history more complete and helps the dietitian identify hidden sources of nutrients and calories before planning suitable advice.
02 If a patient consumes many sweet drinks but eats little food, what is the main nutrition problem?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Empty calories will increase and diet quality will decrease
Explanation: Sugar-sweetened beverages can provide considerable energy while supplying very little protein, fibre, vitamins or minerals. If they replace nutritious meals, the patient may consume excess sugar and calories but still fail to meet requirements for essential nutrients. This pattern is therefore described as an increase in empty calories and a decline in overall dietary quality. The answer is D.
03 Why can local and seasonal foods be priority choices in diet planning?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. They may be available, fresh and affordable
Explanation: Local and seasonal foods are often easier to obtain, fresher and less expensive than foods transported from distant locations or available out of season. Their use can make a diet culturally familiar, practical and more affordable, which supports regular adherence. However, they still need safe handling, adequate variety and appropriate preparation. Being local or seasonal does not automatically make a food healthy, but these factors can make it a useful priority choice. Thus B is correct.
04 Why are fluids and nutrients considered carefully in the diet of a lactating woman?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. To support milk production and the mother's own needs
Explanation: Lactation requires the mother to produce breast milk while maintaining her own body functions and nutrient stores. Adequate fluids, energy, protein, vitamins and minerals support milk production and maternal recovery. The diet should be balanced rather than restricted to water or deprived of protein. Hence, option B is correct.
05 Why should nutritional quality be checked in a patient with repeated infections?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Energy, protein, vitamins and minerals support immune defence functions
Explanation: Adequate nutrition supports the immune system. Protein is needed for immune cells and antibodies, while vitamins and minerals such as vitamins A, C and D, zinc and iron contribute to protective and repair processes. Poor intake can weaken resistance and recovery, although repeated infections also require medical evaluation. Thus, option A is correct.
06 Why may regular supply of water-soluble vitamins be necessary?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Because their storage in the body may be limited
Explanation: Most water-soluble vitamins, especially the B-group vitamins and vitamin C, are not stored in large reserves in the body. Excess amounts are generally excreted in urine, although some exceptions exist. Therefore, regular intake from a varied diet helps maintain normal metabolism, blood formation, immunity and tissue maintenance.
07 Adding iodized salt near the end of cooking may be better for what purpose?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. To reduce iodine loss
Explanation: Iodine is relatively sensitive to heat, moisture and prolonged cooking. Adding iodized salt toward the end of cooking, keeping it covered and storing it in a dry, closed container can help retain more iodine. This practice supports prevention of iodine-deficiency disorders, although it does not make salt a source of protein or fibre.
08 Why is fluid intake important while increasing fibre in a constipated patient?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Because adequate water with fibre helps bowel movement
Explanation: Dietary fibre adds bulk and can hold water in the intestine, making stools softer and easier to pass. When fibre intake is increased without enough fluid, stools may become bulky, dry, or difficult to move, and discomfort can worsen. Therefore, adequate water together with a gradual fibre increase supports normal bowel movement. The exact fluid advice should consider the patient’s medical condition, such as kidney or heart disease, and professional guidance.
09 Which process becomes essential when a patient's nutritional needs change over time?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Regular reassessment of nutritional needs
Explanation: A patient's nutritional requirements may change because of disease progression, recovery, age, physical activity, treatment, appetite or laboratory findings. Regular reassessment allows the professional to update energy, protein, fluid and other nutrient recommendations. This makes the plan safer, more relevant and more effective.
10 If a patient cannot understand the diet plan, what improvement is most necessary in counselling?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Using simple language, household measures and practical examples
Explanation: Effective dietary counselling should be clear, respectful and adapted to the patient's literacy, language and daily routine. Simple words, household measures such as cups or spoons, demonstrations and familiar food examples help the patient understand exactly what to eat and how much. Better understanding improves confidence and adherence.
11 In which situation would giving only supplements not be considered a complete nutrition solution?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. When an affordable food-based improvement is possible
Explanation: Supplements can be useful when a deficiency is diagnosed, requirements are unusually high, or food intake is not sufficient. However, they should not automatically replace a varied and affordable diet. When suitable foods can correct the problem, food-based improvement also supplies fibre, energy and other beneficial components and is usually more sustainable.
12 A patient has low appetite and feels nausea from food smell, which dietary change is suitable?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Giving light, low-odour food in small portions
Explanation: Nausea can be triggered or worsened by strong food smells and by serving a large quantity at once. Light, mildly flavoured, low-odour foods offered in small, frequent portions are usually easier to tolerate. Food should not be stopped completely because inadequate intake may worsen weakness and nutritional deficiency. The patient’s tolerance, hydration, and medical advice should also be considered.
13 If a patient's diet is safe but cannot be prepared correctly at home, what is the main nutrition barrier?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Problem of practical implementation at home
Explanation: A diet may be scientifically safe and nutritionally suitable, yet fail if the patient or family cannot prepare it properly. This is a practical implementation barrier involving skills, equipment, time, cost, or understanding of instructions. Nutrition counselling should therefore use clear demonstrations, realistic substitutions, and follow-up to check whether the prescribed plan can actually be followed at home.
14 If a patient's food is mostly based on packaged snacks, which checking should be prioritized?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Amount of sodium, sugar, fat and fibre
Explanation: Packaged snacks should be evaluated through the nutrition information and ingredient list rather than their appearance or advertising. Many such foods are high in sodium, added sugar, or saturated fat and may provide little fibre or micronutrient value. Checking these nutrients helps identify risks, compare products, and guide the patient toward a more balanced and less processed eating pattern.
15 If a patient is losing weight but says he is eating, what is the next expert step?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Taking a diet history of actual quantity, frequency and tolerance
Explanation: Reported eating does not always show the patient’s actual energy and nutrient intake. Weight loss may result from small portions, infrequent meals, poor absorption, vomiting, pain, food intolerance, or increased requirements. A detailed diet history should record foods, quantities, timing, frequency, preparation, symptoms, and tolerance. This objective assessment is more useful than blaming the patient or making assumptions.
16 Why can body building be affected even when protein intake is adequate if energy intake is deficient?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Protein may be used to provide energy instead of building and repairing tissues
Explanation: When the diet does not provide enough energy from carbohydrates and fats, the body may break down amino acids from protein and use them as fuel. This reduces the protein available for growth, tissue repair, enzymes and other body functions. This is called the protein-sparing principle: adequate energy helps protein perform its main constructive role.
17 When can a very low-fat diet become a problem because of fat-soluble vitamins?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. When some dietary fat is needed to support absorption of these vitamins
Explanation: Vitamins A, D, E and K are fat-soluble, so their digestion and absorption are supported by dietary fat and bile. A severely fat-restricted diet may therefore reduce the absorption of these vitamins, even if the foods contain them. The correct principle is moderation: fat should not be excessive, but some healthy fat is important in a balanced diet.
18 Why is a regular diet important for preventing deficiency of water-soluble vitamins?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Because their storage in the body may be limited
Explanation: Most water-soluble vitamins, especially the B-group vitamins and vitamin C, are not stored in large amounts in the body, although vitamin B12 is an important exception. Excess quantities are generally excreted in urine. Consequently, regular consumption of varied foods helps maintain a continuing supply and lowers the risk of deficiency. They are not the body’s main energy source.
19 Adding vitamin C-rich food to a meal containing plant-source iron demonstrates which expert nutrition principle?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Support for nutrient absorption
Explanation: Plant foods mainly provide non-haem iron, whose absorption is generally lower than that of haem iron from animal foods. Vitamin C helps by reducing ferric iron to the more absorbable ferrous form and by forming soluble compounds in the intestine. Thus, combining foods is a useful nutrient-interaction strategy, although it does not replace medical treatment when iron deficiency is diagnosed.
20 What is the most important nutrition precaution when changing food texture in a soft diet?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Maintain adequate energy, protein and micronutrient balance
Explanation: A soft or modified-texture diet changes the physical form of food, not the patient’s requirements for energy and nutrients. Meals should therefore remain nutritionally dense and provide adequate protein, energy, vitamins, minerals and fluids in a texture that the patient can safely manage. Removing protein or serving only liquids can lead to inadequate intake, weight loss and delayed recovery.
21 Why is attention to water necessary when increasing fibre for a patient with constipation?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Because adequate fluid with fibre supports bowel movement
Explanation: Dietary fibre, particularly soluble and gel-forming fibre, holds water and can help soften and increase stool bulk. Adequate fluid allows fibre to work more effectively and supports easier bowel movement. Increasing fibre suddenly without enough fluid may cause bloating or worsen discomfort, especially in some patients. Fluid advice must still be individualized when kidney or heart disease is present.
22 Checking sodium, sugar, and fat on food labels helps a nutrition expert make which decision?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Assess dietary risk and select suitable foods
Explanation: Comparing sodium, sugar, and fat on a label helps the expert identify dietary risks and select foods appropriate for the person’s health needs. Lower-sodium choices may benefit someone with hypertension, while limiting added sugar and saturated fat may help in diabetes, obesity, or heart disease. The serving size and number of servings must also be checked because package size alone does not show nutritional quality. Food should support, never replace, prescribed medical treatment.
23 If a patient frequently consumes canned foods, which information should the dietitian check first?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Information about sodium, sugar, fat, and preservatives
Explanation: Canned and packaged foods may contain substantial amounts of sodium, added sugar, fat, and certain additives. Reading the nutrition label and ingredient list helps the dietitian identify these components and judge whether the product is suitable for the patient's condition. Therefore, option A is the correct priority.
24 If a patient can eat dry chapati but cannot tolerate dal, which aspect of eating ability should be checked?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Tolerance, taste, and digestive response
Explanation: A patient’s ability to accept one food does not prove that every food will be acceptable. Dal may differ from dry chapati in texture, taste, fibre, protein content, preparation, or digestive tolerance. The nutrition professional should assess the patient’s individual response, preferences, symptoms, and ability to digest the food, rather than judging acceptance only by the food’s appearance.
25 If a patient swallows food with very little chewing, what precaution can be included in nutrition planning?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Suitable texture and advice to eat slowly
Explanation: Swallowing food with inadequate chewing can increase the risk of choking, discomfort, and incomplete digestion, particularly when food is hard, dry, or poorly prepared. A suitable texture, small bites, adequate moisture, upright posture, and advice to eat slowly may improve safety. The plan should be individualised and, when necessary, discussed with the healthcare team.
