Scenario 1: The New Patient with Vague Symptoms
A 55-year-old female presents to your clinic complaining of persistent fatigue, weakness, and occasional dizziness. She states she has been feeling "run down" for the past few months. On general physical examination, you note her skin appears slightly pale, but there are no obvious specific physical signs of deficiency like angular stomatitis or Bitot's spots. She denies any recent changes in diet, but her recollection is vague.
Selected Primary Method: Biochemical Tests
Imagine the following laboratory results come back for this patient. Your task is to interpret these key results to identify any potential nutritional deficiencies and suggest a primary nutritional diagnosis.
Patient Lab Results:
| Test | Result | Reference Range |
|---|---|---|
| Hemoglobin (Hb) | 9.8 g/dL | 12.0 - 15.5 g/dL |
| Serum Ferritin | 10 ng/mL | 20 - 200 ng/mL |
| Serum Vitamin B12 | 180 pg/mL | 200 - 900 pg/mL |
| Serum Folate | 8 ng/mL | > 3 ng/mL |
| Serum Albumin | 3.9 g/dL | 3.5 - 5.0 g/dL |
| Fasting Blood Glucose | 95 mg/dL | 70 - 99 mg/dL |
AI Expert Explanation:
Scenario 2: Screening Children in a Community Health Camp
You are part of a public health team conducting a health camp in a rural village. Your goal is to identify children aged 1-5 years who are at risk of malnutrition (stunting or wasting) on a large scale, quickly and cost-effectively, so they can be referred for further intervention. You have limited time and resources.
Selected Primary Method: Anthropometry
You have collected anthropometric data for 10 children. Your task is to classify their nutritional status based on the WHO Child Growth Standards.
Child Anthropometric Data:
*The image above shows the raw anthropometric data for 10 children.*

Scenario 3: Investigating Dietary Patterns and Taboos
You are assessing Smt. Meena, a 25-year-old woman (50 kg) from the Irula tribe in South India, who recently had a normal vaginal delivery and is exclusively breastfeeding. She is illiterate and an agricultural laborer. You conducted a 24-hour dietary recall.
Selected Primary Method: Dietary Assessment
Your task is to analyze her dietary recall and identify any food taboos or myths she reported. Additionally, calculate her estimated total caloric and protein intake from the recall.
Smt. Meena's 24-Hour Dietary Recall:
| Time | Food/Drink Consumed | Quantity/Portion Size | Notes/Comments |
|---|---|---|---|
| 6:00 am | Warm water with boiled fenugreek seeds | 1 glass | Traditional for lactation and digestion |
| 7:30 am | Idli | 2 medium size | Easy to digest, energy-rich |
| 10:00 am | Coffee | 1 glass (250ml) | Galactogogue |
| 12:30 pm | Cooked rice | 1 cup | Gives strength to the body |
| Boiled greens (local leafy vegetables) | 1/2 cup | Believed to aid recovery | |
| 5:00 pm | Coffee | 1 glass | Galactogogue |
| 7:00 pm | Bread slice roasted with oil | 4 in number | Easy to digest, acts as galactogue |
| 9:00 pm | Warm water | 1 glass | Hydration |
Food Taboos and Myths Reported:
Avoided Foods:
- Cold foods and drinks: Raw fruits (banana, mango), curd, buttermilk, and cold water are avoided due to belief that they cause “coldness” leading to poor milk supply and infant colic.
- Spicy and oily foods: Onion, garlic, chili, and fried foods are avoided to prevent “heat” in the body and stomach upset.
- Heavy meats: Red meat and fish are generally avoided for 40 days postpartum; only local chicken or freshwater fish might be consumed in some tribes but often avoided by Meena’s family.
- Certain vegetables: Brinjal, cabbage, and gourd are avoided as they are believed to cause gas or interfere with breastmilk quality.
- Leftover food: Only freshly cooked food is consumed, as leftovers are thought to cause weakness and illness.
Beliefs and Practices:
- Ghee and jaggery: Consumed in small amounts to strengthen the body and improve lactation.
- Herbal decoctions: Local herbs such as tulsi (holy basil), ginger, and fenugreek are used to promote recovery and milk production.
- Millets and red rice: Preferred staples believed to provide strength and energy.
- Avoidance of “cold” foods: Concept of “hot” and “cold” foods governs diet; postpartum is considered a “hot” state requiring warm, easily digestible foods.
- Special postpartum dishes: Parboiled rice porridge (kanji) and herbal powders (similar to kalathu powder) are commonly prepared to aid healing.
Estimated Caloric and Protein Intake from Smt. Meena's Recall:
Appropriate Recommended Daily Intake for Smt. Meena:
Based on her status as a 25-year-old (50 kg) homemaker (sedentary) who is lactating (0-6 months postpartum), determine her recommended daily intake.

Scenario 4: Assessing Family Dietary Intake & Factors
You are assessing a family of four: Father (35 years old, clerk, CU=1), Mother (32 years old, homemaker, CU=0.9), Son (10 years old, student, CU=0.8) and Daughter (6 years old, student, CU=0.6).
The concept of Consumption Units (CU) is used to standardize dietary intake across different age and activity groups. **1 CU is equivalent to 2400 Calories and 60 grams of Protein.**
The family purchases the following raw food items for one month, and you are to calculate their daily dietary intake based on the concept of consumption units (CU).
Selected Primary Method: Ecological Assessment & Vital Statistics
Your task is to identify potential nutritional deficiencies or excesses based on their food purchases.
Family Monthly Food Purchases:
| Food Item | Total Bought (kg/month) |
|---|---|
| Milled Rice | 18 |
| Wheat flour, atta | 9 |
| Red gram | 4 |
| Black gram | 3 |
| Cow Milk | 30 (liters) |
| Onion | 6 |
| Tomato, ripe, local | 5 |
| Potato brown small | 2 |
| Oil | 2 (liters) |
| Sugar | 1.5 |
| Eggs | 30 |
| Ground nuts | 0.5 |
Scenario 5: Assessing a Suspected Vitamin Deficiency
A patient presents with specific neurological symptoms, including tingling and numbness in their extremities. They also report difficulty with coordination. Based on their medical history (gastric bypass surgery a few years ago), you highly suspect a specific B vitamin deficiency. You need a definitive diagnosis to initiate targeted treatment.
Selected Primary Method: Biochemical Tests
Given the patient's symptoms and history, your primary suspicion is Vitamin B12 deficiency. Here are the lab results for B vitamins.
Patient's Lab Results for B Vitamins:
| Test | Result | Reference Range |
|---|---|---|
| Hemoglobin (Hb) | 9.8 g/dL | 12.0 - 15.5 g/dL |
| Serum Ferritin | 10 ng/mL | 20 - 200 ng/mL |
| Serum Vitamin B12 | 180 pg/mL | 200 - 900 pg/mL |
| Serum Folate | 8 ng/mL | > 3 ng/mL |
| Serum Albumin | 3.9 g/dL | 3.5 - 5.0 g/dL |
| Fasting Blood Glucose | 95 mg/dL | 70 - 99 mg/dL |
Scenario 6: Tailored Dietary Planning
A 22-year-old woman, educated up to 10th grade and currently a homemaker, presents with a missed period and a positive urine pregnancy test. She reports no nausea, vomiting, or other symptoms.
**Your Task:** Prepare a tailored balanced dietary plan for 1 day (24hrs) to meet her caloric and protein needs essential for fetal growth and maternal health.
**Reference:** For an adult woman (homemaker, sedentary activity), the baseline caloric requirement is 1900 kcal/day. During pregnancy, an additional 350 kcal/day is needed. The baseline protein requirement is 55g/day. During pregnancy, the recommended protein intake is 75g/day.
**Total Target:** Approximately **2250 Calories** and **75g Protein** per day.
Select food items and quantities for each meal, then calculate the total calories and protein for your plan.
