Good source of vitamin-D includes EXCEPT?

Appeared in: WCL Staff Nurse - 2019

Explanation

Blueberries are fruits and, like most plant-based foods, do not naturally contain or are not typically fortified with Vitamin D.
The question requires identifying the exception among a list of Vitamin D sources.
Vitamin D is primarily found in animal products, fortified foods, and is synthesized through sun exposure.

Option B: Sunlight is a primary and major source of Vitamin D. The body synthesizes Vitamin D₃ (cholecalciferol) in the skin upon exposure to UVB radiation.
Option C: Sea-fishes, particularly fatty fish like salmon, mackerel, and tuna, as well as fish liver oils, are the richest natural dietary sources of Vitamin D.
Option D: Dairy products like milk, yogurt, and cheese are common and significant dietary sources of Vitamin D, largely because they are often fortified with it.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Sources of Vitamin D as background academic context rather than a clinical decision trigger.
Nurses play a key role in identifying patients at risk for Vitamin D deficiency, such as the elderly, individuals with limited sun exposure, and those with malabsorption syndromes.
Patient education is crucial. Nurses should advise on safe sun exposure (e.g., 10-15 minutes of midday sun on arms and legs a few times a week) and dietary sources.
What if? If a patient has chronic kidney disease, they cannot effectively convert Vitamin D into its active form (calcitriol). Therefore, simply providing standard Vitamin D sources would be insufficient; they would require supplementation with an active form of Vitamin D.

How to Approach the Question

First, identify the negative keyword 'EXCEPT' in the question. This means you are looking for the option that does not fit with the others.
The question asks for good sources of Vitamin D. Your goal is to find the one option that is NOT a good source.
Evaluate each option: Is 'Sunlight' a source of Vitamin D? Yes. Is 'Sea-fishes' a source? Yes. Is 'Dairy Products' a source? Yes.
Evaluate the final option: Is 'Blueberries' a source of Vitamin D? No.
The option that is the exception is the correct answer.
