Question

What are the clinical findings associated with the flattening of the nail plate with an increased smoothness of the nail surface?

1) Iron deficiency (with or without anemia)
2) Poorly controlled diabetes (>15 yrs in duration)
3) Local injury
4) All of the above

Answer 1

The flattening of the nail plate with increased smoothness is most accurately associated with iron deficiency, which can cause thin, flat, or concave nails, a condition known as koilonychia.

Step-by-step explanation:

The clinical findings associated with a flattening of the nail plate and an increase in the smoothness of the nail surface can be related to several health issues. In the context of the options provided, the most accurate answer is iron deficiency (with or without anemia). Iron deficiency can affect the growth and appearance of nails, often leading to a condition known as koilonychia, or spoon nails, where the nails become thin, flat, or even concave with a raised edge. While poorly controlled diabetes for over 15 years may cause many complications, it is not commonly associated with this specific nail change. A local injury to the nail can cause temporary changes in the nail plate appearance but would not typically result in increased smoothness of the nail surface.
