Question 1

Why is a very low-energy diet not suitable for weight loss in a lactating mother?

Accepted Answer

It may affect maternal nutrition and milk production Lactation requires additional energy and nutrients for milk synthesis and maternal recovery. An excessively restrictive diet can cause fatigue, inadequate protein and micronutrient intake, loss of lean tissue, and potentially reduced milk production in some circumstances. Weight management should therefore be gradual, nourishing, and individualized, with adequate fluids and professional guidance rather than crash dieting.

Question 2

How can multiple medicines affect nutritional status in an elderly patient?

Accepted Answer

Appetite, taste, or nutrient absorption may be affected Polypharmacy can cause nausea, constipation, diarrhoea, dry mouth, early satiety, altered taste, sedation, or appetite loss. Some medicines also change gastric conditions, metabolism, or absorption of nutrients, while nutrients may alter drug action. A complete nutrition assessment should therefore include medication history, observed intake, weight change, symptoms, and communication with the prescriber.

Question 3

What is the most balanced dietary goal when obesity and diabetes coexist?

Accepted Answer

Maintain glucose stability with energy control When obesity and diabetes coexist, the plan should create a safe, sustainable energy deficit while distributing appropriate carbohydrate, protein, and fat across meals. Portion control, high-fibre foods, activity as medically permitted, and glucose monitoring support both goals. Eliminating all carbohydrates is unnecessary and may reduce dietary quality; individualized medical advice is required for medicines and glucose targets.

Question 4

If weight increases after nutrition intervention but oedema also increases, how should the result be interpreted?

Accepted Answer

Carefully, because weight gain may also be due to fluid A rise in body weight is not automatically evidence of improved nutrition when oedema is present. Accumulated extracellular fluid can increase weight while muscle tissue remains depleted. Therefore, interpretation should include oedema assessment, intake, functional status, physical examination, and relevant medical or biochemical findings.

Question 5

Which is the most important principle in expert clinical nutrition decision making?

Accepted Answer

Integrating disease, assessment, tolerance and practicality Expert clinical nutrition decisions must be individualized. The practitioner considers the diagnosis, nutritional assessment, laboratory and physical findings, gastrointestinal tolerance, cultural preferences, available foods, finances, and the patient’s ability to follow the plan. A scientifically ideal diet is ineffective if it is unsafe, unaffordable, unacceptable, or impossible to maintain.

Question 6

Why should body weight be interpreted carefully when a patient has oedema?

Accepted Answer

Because oedema can hide true nutritional deficiency Oedema is an abnormal accumulation of fluid in the tissues. This extra fluid can increase or maintain body weight even when the patient has lost muscle, body protein, or fat. Consequently, body weight alone may underestimate the severity of malnutrition. A proper assessment should also consider swelling, recent weight change, muscle stores, dietary intake, illness, and other clinical findings.

Question 7

Which observation is more useful to identify muscle wasting in serious illness?

Accepted Answer

Loss of shoulder and thigh muscles Muscle wasting is identified through a relevant physical examination, not through unrelated environmental observations. Visible loss around the shoulders, temples, clavicles, ribs, hands, thighs, or calves can indicate reduced muscle stores. In serious illness, inflammation and inactivity may accelerate catabolism, so physical findings should be interpreted together with intake history, weight trends, function, and disease severity.

Question 8

Why can it be wrong to consider low serum albumin as only protein deficiency?

Accepted Answer

Because it can also be affected by inflammation and infection Serum albumin is a blood protein, but its concentration is influenced by more than dietary protein intake. Inflammation, infection, liver dysfunction, kidney loss, fluid overload, and changes in distribution can lower it. Because albumin responds slowly and is affected by illness, it should not be used alone to diagnose protein malnutrition; dietary history, examination, weight change, and inflammatory status are also required.

Question 9

What should be the main focus of diet planning for a patient with metabolic stress?

Accepted Answer

Adequacy of energy, protein and micronutrients Metabolic stress, such as that caused by severe infection, trauma, surgery, or burns, can increase energy expenditure and protein breakdown. Diet planning should therefore provide adequate energy and high-quality protein, while also supplying vitamins, minerals, fluids, and electrolytes according to the patient’s condition. Intake must be individualized and monitored to avoid both underfeeding and excessive feeding.

Question 10

Why is zinc considered important in wound healing?

Accepted Answer

It supports cell growth and tissue repair Zinc is an essential trace mineral involved in DNA and protein synthesis, cell division, immune function, and the formation and repair of tissues. These processes are necessary for wound closure and resistance to infection. Zinc deficiency may delay healing, but supplementation should be based on clinical assessment because excessive zinc can interfere with copper balance and is not a substitute for adequate energy, protein, or wound care.

Question 11

Why is attention to meal and medicine balance important on exercise days in diabetes?

Accepted Answer

Because exercise can affect blood glucose Physical activity increases glucose use by muscles and can lower blood glucose during exercise or several hours afterward. If meals are delayed, carbohydrate intake is inadequate, or insulin and other medicines are not adjusted appropriately, hypoglycaemia may occur; in some situations intense stress can instead raise glucose. Exercise timing, meals, medication, hydration, and glucose monitoring must therefore be coordinated.

Question 12

When should potassium-rich foods be advised cautiously in hypertension?

Accepted Answer

When kidney disease is also present Potassium-rich foods may help many people with hypertension, but the advice is not universal. In kidney disease, impaired renal excretion can cause potassium to accumulate in the blood. Certain medicines, including potassium-sparing diuretics and some renin–angiotensin system blockers, can also raise potassium. The patient’s kidney function, medicines, and serum potassium should be reviewed before giving individualized advice.

Question 13

What is the most correct basis for advising reduction of trans fat in a heart patient?

Accepted Answer

It can worsen lipid profile and heart risk Industrial trans fats adversely affect cardiovascular health by raising LDL cholesterol, lowering HDL cholesterol, and contributing to inflammation and endothelial dysfunction. These changes increase the risk of coronary heart disease. A heart patient should therefore limit foods containing partially hydrogenated oils and many commercially fried or processed products, while replacing them with healthier unsaturated fats in appropriate amounts.

Question 14

On what should fluid control in kidney disease be based?

Accepted Answer

Urine output, oedema and medical advice Fluid prescription in kidney disease depends on kidney function, urine output, interdialytic weight change, oedema, blood pressure, serum electrolytes, heart status, and the treatment stage. Some patients need restriction while others do not. It must therefore be individualized and guided by the renal team, not by guesswork.

Question 15

Why may sodium control be necessary in a dialysis patient?

Accepted Answer

It may relate to fluid thirst and blood pressure control Excess sodium increases thirst and encourages fluid intake. In a dialysis patient, limited urine production may prevent the extra fluid from being removed, causing interdialytic weight gain, oedema, and higher blood pressure. Sodium advice should be individualized and coordinated with the dialysis prescription and overall renal diet.

Question 16

Why may long fasting be avoided in liver cirrhosis?

Accepted Answer

Muscle breakdown and energy deficit may increase In cirrhosis, glycogen stores may be limited and the body can enter a fasting-like metabolic state sooner than usual. During a long overnight or daytime fast, it may use fat and muscle protein for energy, worsening sarcopenia and malnutrition. Individualized small, frequent meals and sometimes a late-evening carbohydrate-containing snack can help maintain energy availability, subject to medical advice.

Question 17

What is most important while deciding fat amount in pancreatic disease?

Accepted Answer

Fat tolerance and medical condition of patient Pancreatic disorders can reduce the delivery of digestive enzymes to the intestine and may impair fat digestion and absorption. However, the appropriate amount of fat varies with the diagnosis, symptoms, malabsorption, enzyme replacement, nutritional status, and treatment plan. Excessive restriction can cause energy and essential fatty-acid deficiency, so fat should be individualized and monitored rather than automatically eliminated.

Question 18

Why is leaving tube feeding formula too long at room temperature risky?

Accepted Answer

It can increase microbial growth Tube-feeding formula is nutrient-rich and can support rapid multiplication of bacteria and other microorganisms when left at room temperature for too long, especially after opening or preparation. Contamination may cause diarrhoea, vomiting, sepsis, or other infection. Safe practice includes hand hygiene, clean equipment, correct storage, labelled preparation time, refrigeration when appropriate, and discarding formula according to institutional guidance.

Question 19

What is the main basis for choosing between oral supplement and tube feeding?

Accepted Answer

Patient's oral intake ability and nutrition need The route of nutrition is selected after assessing whether the patient can safely chew, swallow, and consume enough food to meet requirements. An oral supplement may be suitable when the patient can swallow safely but ordinary intake is inadequate. If oral intake remains insufficient and the gastrointestinal tract functions, enteral tube feeding may be considered. Decisions also include aspiration risk, prognosis, preferences, and clinical goals.

Question 20

Why should nutrition-intervention results not be measured only by patient satisfaction?

Accepted Answer

Biological and measurable health indicators are also needed Patient satisfaction is valuable because taste, comfort, culture and acceptability influence adherence, but it does not prove that nutritional status has improved. Weight trend, intake records, muscle status, biochemical tests, symptoms and disease-specific outcomes may also be needed. Using multiple indicators gives a safer and more complete evaluation of intervention success.

Question 21

If weight gain occurs with breathlessness and oedema, what should be considered in nutrition review?

Accepted Answer

Possibility of increased fluid load A rapid increase in body weight accompanied by breathlessness and oedema may reflect fluid retention rather than improved muscle or nutritional tissue. This can occur in cardiac, renal, hepatic or other medical conditions and requires prompt clinical assessment. Weight should therefore be interpreted with symptoms, fluid balance, examination and relevant tests rather than alone.

Question 22

Why can high waist fat be concerning even when BMI is normal?

Accepted Answer

It may be linked with metabolic risk BMI compares weight with height but does not show where body fat is stored or distinguish fat from muscle. Excess abdominal or visceral fat may be associated with insulin resistance, abnormal lipids, hypertension and cardiovascular risk even when BMI falls in the normal range. Waist measurement and other clinical factors therefore add useful information.

Question 23

Why should a dietitian understand the difference between food allergy and intolerance?

Accepted Answer

For safe and accurate diet modification A food allergy involves an immune reaction and can sometimes cause a rapid, life-threatening response, whereas intolerance generally involves non-immune difficulty digesting or processing a food. Distinguishing them prevents unnecessary restriction, identifies risks, guides referral, and supports an accurate, nutritionally adequate diet plan.

Question 24

If a dietitian changes a hospital patient’s diet after reviewing reports and food tolerance, which part of the scope is shown?

Accepted Answer

Clinical nutrition care Reviewing laboratory or clinical reports and then adjusting a patient’s diet according to tolerance is individualized clinical nutrition care. The dietitian uses health information, symptoms, treatment needs, and the patient’s ability to consume foods safely. The other options are unrelated occupations, so option A is the only appropriate answer.

Question 25

If a nutrition expert runs an anaemia-prevention programme for adolescent girls, which dual scope is shown?

Accepted Answer

Adolescent nutrition and public health Adolescent girls are a nutritionally important population because iron requirements rise during growth and menstrual blood loss can increase anaemia risk. A prevention programme may combine screening, iron-rich food education, supplementation according to policy, and referral. It therefore joins adolescent nutrition with public health, making D correct.
