Introduction

Correct answer: A. Disease severity and the patient’s activity level

Explanation: Energy requirements during illness are individualized. Fever, infection, inflammation, trauma, surgery, burns, and other conditions can increase metabolic demands, while immobility may reduce activity-related expenditure. The dietitian therefore considers disease severity, stress response, activity, age, body size, nutritional status, and treatment goals rather than using a single value for every patient. Hence, option A is the relevant factor.

Correct answer: A. Severity of risk and the patient's immediate nutritional need

Explanation: Clinical nutrition services should first address patients whose nutritional risk is severe, whose intake is inadequate, or whose condition may worsen without prompt support. Prioritization may consider recent weight loss, poor intake, swallowing problems, critical illness, or other urgent concerns. Appearance, kitchen convenience, or a fixed order should never replace clinical judgement and patient need.

Correct answer: D. Modify the diet gradually according to tolerance

Explanation: When tolerance is reduced, sudden large portions or unsuitable foods may worsen nausea, pain, bloating, diarrhoea, or refusal to eat. The diet should be adjusted gradually by considering symptoms, texture, portion size, meal frequency, and medical advice. Monitoring the response allows safe progression while protecting energy and nutrient intake as far as possible.

Correct answer: B. Preference should be safe and suitable for nutrition goals

Explanation: Respecting a patient’s food preference can improve acceptance, satisfaction, and long-term adherence to a diet plan. However, preference cannot override safety or therapeutic requirements. The selected food must be compatible with the patient’s disease, allergies, swallowing ability, cultural needs, nutrient targets, and prescribed restrictions. Thus, a preferred food is appropriate when it can be included safely and still supports the nutritional goals of treatment, sometimes with a suitable portion or modification.

Correct answer: A. To reduce digestive problems caused by milk sugar

Explanation: Lactose is the natural sugar in milk. In lactose intolerance, inadequate lactase activity can cause bloating, abdominal pain, gas, or diarrhoea after consuming lactose. Diet planning aims to reduce symptoms by adjusting lactose quantity, using lactose-free or lower-lactose products, and preserving calcium and vitamin D through suitable alternatives rather than removing all protein or fruit.

Correct answer: B. An obese patient with heart risk

Explanation: An obese patient with cardiovascular risk may benefit from a carefully planned reduction in energy and saturated or excess fat, alongside appropriate physical activity and medical care. The goal is gradual, nutritionally adequate weight management rather than starvation. Underweight, infected, wounded, or severely malnourished patients may instead need additional energy and protein, depending on assessment.
