The nurse observes the presence of brittle, concave curves to the nails of a client on assessment. Which information should the nurse obtain from the client that may explain the appearance of the nails?
A.
Coronary heart disease.
B.
Iron deficiency anemia.
C.
Diabetes mellitus.
D.
Recent candida Infection.
The Correct Answer and Explanation is:
The correct answer is B. Iron deficiency anemia.
Brittle nails with concave curves, also known as koilonychia or spoon nails, are a classic sign of iron deficiency anemia. In this condition, the body lacks sufficient iron to produce hemoglobin, the protein in red blood cells responsible for transporting oxygen. When iron levels are low, the body’s ability to carry oxygen diminishes, leading to symptoms like fatigue, weakness, pallor, and changes in the appearance of nails.
The concave or spoon-like shape of the nails in iron deficiency anemia occurs due to impaired keratin production, which weakens the nails and makes them brittle. Over time, the lack of adequate oxygen and nutrients reaching the nail bed due to reduced hemoglobin levels can cause the nails to thin and lose their normal convex shape, resulting in the characteristic concavity.
It’s important for the nurse to explore additional symptoms that could suggest iron deficiency, such as fatigue, dizziness, shortness of breath, or pica (craving non-food substances like ice or dirt). The nurse should inquire about the client’s dietary habits, especially regarding iron-rich foods like meat, beans, and leafy greens, and any history of blood loss, such as heavy menstrual periods or gastrointestinal bleeding, as these can contribute to iron deficiency.
The other options, while relevant to nail health in different ways, are not commonly associated with brittle, concave nails. For example:
- A. Coronary heart disease may affect circulation but does not typically lead to spoon nails.
- C. Diabetes mellitus can lead to nail infections or thickening but is not linked to koilonychia.
- D. Candida infections may affect the nail surface but usually cause discoloration or nail separation rather than spooning.
Therefore, iron deficiency anemia is the most plausible explanation for this client’s nail changes.
