Explanation

• The correct matching is P-2, Q-1, R-3.
• Cow's milk (P) is a standard source of calcium, providing approximately 120 mg per 100g (2).
• Cheese (Q), being a concentrated dairy product, has a much higher calcium content, around 790 mg per 100g (1).
• Cumin seeds (R) are exceptionally rich in minerals, containing about 1040 mg of calcium per 100g (3), which is the highest value among the options.

Why Other Options Were Wrong

• Option A: This option incorrectly matches Cow's Milk (P) with 790 mg (1) and Cheese (Q) with 120 mg (2). This inverts the values, as cheese is far more calcium-dense than milk.
• Option B: This option incorrectly matches Cheese (Q) with 1040 mg (3) and Cumin seeds (R) with 790 mg (1). While both are high in calcium, cumin seeds are exceptionally richer in calcium than cheese.
• Option D: This option incorrectly matches Cow's Milk (P) with 790 mg (1), Cheese (Q) with 1040 mg (3), and Cumin seeds (R) with 120 mg (2). It completely scrambles the values, assigning the lowest calcium content to the richest source (cumin seeds).

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nutritional science and the calcium content of common foods as background academic context rather than a clinical decision trigger.
• Nurses often provide dietary counseling. Knowing the calcium content of various foods is crucial for advising patients on bone health, especially for those at risk for osteoporosis.
• Understanding rich sources of calcium helps in planning diets for pregnant and lactating women, growing children, and post-menopausal women who have increased calcium needs.
• What if? If a patient is lactose intolerant, a nurse cannot simply recommend milk or cheese. They must be able to suggest non-dairy, calcium-rich alternatives like ragi, sesame seeds, leafy greens, and fortified foods.

How to Approach the Question

• First, identify the core concept of the question, which is matching food items to their calcium content.
• Start with the most familiar item. Most people have a general idea that milk is a good source of calcium, but not excessively high. The value of 120 mg is the most reasonable for milk among the choices.
• This establishes the match P-2. Now, look for options that start with P-2. This immediately narrows down the possibilities to options B and C.
• Next, compare Cheese and Cumin seeds. Cheese is concentrated milk, so it will be much higher than milk. Cumin seeds, like many seeds, are often very dense in minerals. It's logical that cheese would have a high value (790 mg) and cumin seeds would have the highest value (1040 mg).
• This leads to the matching Q-1 and R-3.
• Combine the findings: P-2, Q-1, R-3. This corresponds to the correct option.
