Explanation

Listen in Hindi

• The correct option correctly pairs each essential fatty acid with its primary dietary source.
• Linoleic acid (omega-6) is rich in vegetable oils like safflower oil.
• Arachidonic acid (omega-6) is primarily sourced from animal products like meat.
• Linolenic acid (omega-3) is found in plant-based oils such as soybean oil.
• Eicosapentaenoic acid (EPA, an omega-3) is most abundant in marine sources like fish oil.

Why Other Options Were Wrong

• Option B: This option incorrectly matches Linoleic acid with Meat and Arachidonic acid with Soybean oil. Linoleic acid is from plant oils, and Arachidonic acid is from animal sources.
• Option C: This option incorrectly pairs all items. For example, it matches Linoleic acid with Fish oil and Arachidonic acid with Safflower oil, which is the reverse of their primary categories (plant vs. animal/marine).
• Option D: This option incorrectly matches Linoleic acid with Soybean oil (while a source, Safflower is richer and the better match here), Arachidonic acid with Fish oil, and Eicosapentaenoic acid with Meat. These pairings confuse plant, animal, and marine sources.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Dietary sources of essential fatty acids as background academic context rather than a clinical decision trigger.
• Nurses educate patients on dietary modifications for various health conditions. Knowing the sources of essential fatty acids is crucial for advising patients on managing inflammation, cardiovascular health, and neurological function.
• A balanced intake of omega-6 (like linoleic acid) and omega-3 (like linolenic and EPA) fatty acids is vital. The typical Western diet is high in omega-6 and low in omega-3, which can promote inflammation. Nurses can guide patients to increase omega-3 sources like fish and flaxseed.
• What if? A patient with high triglycerides is advised to increase omega-3 intake but is a strict vegetarian. The nurse would recommend sources of alpha-linolenic acid (ALA) like flaxseed oil, chia seeds, and walnuts, instead of fish oil (EPA/DHA), and explain that the body's conversion of ALA to EPA/DHA is limited.

How to Approach the Question

• First, identify the type of question. This is a 'Match the Following' question requiring knowledge of nutrition.
• Read both lists carefully. List I contains specific names of fatty acids, and List II contains food sources.
• Try to match at least one or two items you are certain about. For example, many people know that fish oil is a key source of omega-3s like EPA.
• Based on the match 'd-II' (Eicosapentaenoic acid - Fish oil), look at the options. Options A and B both contain 'd-II'. This eliminates options C and D.
• Next, consider another item. Arachidonic acid is known to come from animal sources. Therefore, 'b-I' (Arachidonic acid - Meat) is a likely match.
• Check the remaining options. Only option A has both 'd-II' and 'b-I'.
