Question 1EasyLevel 2
What does menu planning mean in diet service?
Correct answer: D
Menu planning is the process of deciding in advance which foods and dishes will be served at particular meals. In a diet service, the plan should consider the nutritional requirements, medical restrictions, allergies, preferences, budget, available ingredients, staff, and facilities. A medicine list, staff timetable, or equipment inventory may support food-service administration, but none of these is the meaning of menu planning.
Why may a patient's sleep and routine be considered in diet planning?
Correct answer: B
A patient's sleep pattern, daily activities, treatment schedule, and appetite can help the dietitian or caregiver choose practical meal times. Meals and snacks planned around medicines, examinations, therapy, and rest are more likely to be eaten on time. Considering routine does not change the medicine or unrelated household arrangements; it supports regular intake, comfort, and adherence to the prescribed diet.
Cereals such as rice, wheat, maize, oats, and millet are important sources of carbohydrates, especially starch. Carbohydrates are broken down to provide energy for physical activity, body functions, and daily work. Cereals may also supply some protein, fibre, vitamins, and minerals, particularly when whole grains are eaten, but their main nutritional contribution in a typical diet is energy.
Pulses are a good source of which nutrient in the diet?
Correct answer: B
Pulses and legumes, including lentils, chickpeas, kidney beans, peas, and pigeon peas, are valuable plant sources of protein. Protein supplies amino acids needed for growth, maintenance, and repair of body tissues. Pulses also provide carbohydrate, fibre, and several minerals, but protein is the nutrient most strongly associated with this food group. Combining cereals and pulses can improve the overall quality of plant protein.
Milk and milk products are considered good sources of which mineral?
Correct answer: C
Milk and milk products such as yoghurt and paneer are well-known sources of calcium, a mineral needed for the formation and maintenance of bones and teeth. Calcium also participates in muscle contraction, nerve transmission, and blood clotting. Milk contains other nutrients too, including protein and some vitamins, but lead and sand are not nutrients, and sodium is not the defining mineral association tested in this question.
Seasonal foods are often available in abundance during their natural growing period, so they may be fresher, less expensive, and easier to include in a practical diet plan. They can also provide useful nutrients and variety. However, seasonal availability alone does not guarantee that a food is suitable for every patient; the complete nutritional needs and medical condition must also be considered.
When can advising a patient to eat slowly be useful?
Correct answer: C
Advising a patient to eat slowly may be useful when rapid eating causes discomfort, bloating, coughing, poor chewing, or difficulty recognising fullness. Slow eating encourages thorough chewing, gives the body more time to respond to food, and may improve tolerance and intake. It is not a universal treatment, and individual medical advice is still required, but option C expresses the relevant purpose.
A good diet plan should provide appropriate energy and nutrients, follow food-safety principles, and suit the person's age, health condition, food preferences, culture, budget, and daily routine. A plan that is extremely expensive, unclear, or leaves a person constantly hungry is unlikely to be sustainable. Practicality and adherence are therefore as important as nutritional adequacy.
What is asked in a twenty-four-hour diet recall method?
Correct answer: C
The twenty-four-hour dietary recall is a short-term assessment method in which the person reports all foods and beverages consumed during the preceding day or twenty-four-hour period. The interviewer may ask about portions, preparation methods, snacks, and drinks to estimate nutrient intake. It depends on memory and may not represent usual long-term habits. Hence, option C is correct.
Local foods are often available in the patient’s community, less expensive, familiar in taste, and easier to prepare. Using them can make a diet culturally acceptable and financially practical while still supplying required nutrients when the foods are selected in suitable amounts and combinations. Thus, local foods can improve adherence and make diet planning more realistic; option B is correct.
Why are religious beliefs considered in diet planning?
Correct answer: B
Religious beliefs may influence permitted foods, fasting practices, food combinations, preparation methods, and meal timings. Respecting these beliefs demonstrates cultural competence and helps build trust. When medically safe alternatives are offered, the patient is more likely to accept and follow the plan. Dietary planning should balance religious preferences with nutritional adequacy and clinical requirements; therefore, option B is correct.
When is the family’s role important in clinical nutrition?
Correct answer: C
Family support is especially important after discharge or whenever meals are prepared and supervised at home. Family members may purchase suitable foods, follow portion guidance, encourage adherence, help record symptoms, and support changes in cooking practices. Their involvement should respect the patient’s autonomy and preferences, but practical home support can greatly improve continuity and success of the nutrition plan. Thus, option C is correct.
When is a patient’s progress reviewed again in clinical nutrition?
Correct answer: A
A follow-up visit is used to review the patient’s progress after the nutrition plan has been started. The professional may assess food intake, adherence, symptoms, weight, laboratory findings when available, tolerance, and barriers to implementation. The plan can then be continued, modified, or intensified according to the patient’s response. Therefore, option A is correct; an admission form alone cannot show ongoing progress.
What is the purpose of initial screening in clinical nutrition?
Correct answer: A
Initial nutrition screening is a brief, systematic first step used to identify people who may be malnourished or at risk of developing nutrition problems. It may consider recent weight loss, poor appetite or intake, illness severity, and functional concerns. Screening does not replace a complete assessment; it signals the need for timely referral and detailed evaluation by a qualified professional.
Nutrition risk means that a person has an increased possibility of developing a nutrition-related problem or that an existing problem may worsen. It can be associated with poor intake, unintentional weight loss, illness, swallowing difficulty, digestive problems, or increased nutrient needs. Recognising risk helps health professionals arrange further assessment and early nutrition support.
Asking a patient to recall food eaten is a way to get what information?
Correct answer: B
A food recall, commonly a 24-hour recall, asks a patient to describe foods and beverages consumed during a specified period. It provides information about dietary intake, meal patterns, portion sizes, food choices, and sometimes preparation methods. Although memory and estimation can limit accuracy, the recall helps the professional understand intake and plan a suitable nutrition intervention.
A patient’s diet chart records important instructions such as the type and quantity of food, meal timings, permitted or restricted items, and sometimes the required consistency. It helps nurses, dietitians, kitchen staff, patients, and caregivers follow the same plan accurately. Thus, option D is correct because the chart keeps food instructions clear and organised.
What may happen if the diet does not provide enough energy?
Correct answer: A
If the diet supplies less energy than the body needs, stored energy may be used to support basic functions and daily activities. The person may gradually experience weakness, tiredness, reduced concentration, poor work capacity, and, if the deficiency continues, weight loss. Therefore, weakness and fatigue are the appropriate effects. A permanent rise in temperature, sharper vision, or sudden bone lengthening does not result from ordinary energy deficiency. Energy needs depend on age, sex, body size, activity, growth, and health condition.
Why are low-cost nutritious options chosen in diet planning?
Correct answer: B
A diet plan is more useful when it can be purchased and prepared within the person’s available resources. Choosing affordable foods such as locally available cereals, pulses, seasonal vegetables, fruits, or other suitable alternatives can reduce financial barriers while still supplying needed nutrients. Better affordability improves acceptability and long-term adherence. The purpose is not to reduce food quantity or nutrient requirements, and it should never be to confuse the patient. Thus, option B correctly describes practical and economical diet planning.
A sample menu is a practical example of how a patient can arrange meals according to the prescribed diet. It illustrates suitable foods, portions, meal timing, and possible combinations, making dietary advice easier to understand and follow. Therefore, it mainly helps the patient understand appropriate food choices, not unrelated household or technical activities.
What problem may occur due to lack of water in the diet?
Correct answer: C
Insufficient water intake can produce a fluid deficit called dehydration. Common effects include excessive thirst, dry mouth, weakness, headache, dizziness, constipation, and concentrated or dark urine. Scurvy results from vitamin C deficiency, rickets is associated mainly with vitamin D and calcium problems, and goitre commonly involves iodine deficiency. Thus dehydration is the correct answer.
Why is knowing a patient's digestive problem important?
Correct answer: A
A patient's digestive condition affects which foods, textures, quantities, and preparation methods may be tolerated. For example, a person with indigestion may need lighter, less oily, or less irritating foods, while another condition may require a modified consistency or meal pattern. Knowing the problem therefore supports safe and suitable food selection and can reduce discomfort.
What may happen to some patients due to excessive spices in diet?
Correct answer: B
Large amounts of strong spices can irritate the stomach or intestines in some patients, especially those with gastritis, reflux, ulcers, or sensitive digestion. They may experience burning, abdominal discomfort, nausea, or worsened indigestion. Individual tolerance differs, so the diet should be adjusted to the patient's condition and medical advice. Therefore discomfort or irritation is the correct answer.
What is the purpose of giving food slowly and comfortably to a patient?
Correct answer: D
Slow, comfortable feeding gives the patient enough time to sit safely, chew, swallow, and respond to any difficulty. It can support adequate intake and reduce anxiety, coughing, choking, or discomfort, particularly when the patient is weak or has swallowing problems. The purpose is not to rush the meal, reduce appetite, or lower nutrient value; it is to make food intake safer and easier.
Why are restricted items written in a patient's food list?
Correct answer: A
Restricted items are recorded so that the patient, family, and caregivers know which foods may worsen the illness, interact with treatment, cause allergy, or conflict with prescribed dietary limits. A clear list improves communication and reduces accidental exposure to unsuitable foods. It does not mean that food should be withheld altogether; it identifies specific items to avoid while safer alternatives are provided.
