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?

Choice A Reason: Coronary heart disease is incorrect. Coronary heart disease is primarily associated with cardiovascular symptoms such as chest pain, shortness of breath, and fatigue. While some nail changes may occur in individuals with coronary heart disease due to decreased oxygenation, brittle, concave nails are not a typical manifestation of this condition. Therefore, this option is less likely to explain the appearance of the nails. Choice B Reason: Iron deficiency anemia is correct. Iron deficiency anemia is characterized by a lack of iron in the body, leading to decreased production of hemoglobin and red blood cells. One of the classic nail findings associated with iron deficiency anemia is koilonychia, which presents as brittle, concave nails with a spoon-like appearance. This is due to structural changes in the nails caused by the deficiency of iron. Therefore, this option is the most likely explanation for the observed nail changes. Choice C Reason: Diabetes mellitus is incorrect. Diabetes mellitus can lead to various dermatologic manifestations, including nail changes such as thickening, discoloration, and slow nail growth. However, brittle, concave nails with a spoon-like appearance are not typically associated with diabetes mellitus. Therefore, while diabetes mellitus may affect the nails, it is less likely to explain the specific appearance observed in this case. Choice D Reason: Recent candida infection is incorrect. Candida infections, particularly in the nail folds (paronychia), can lead to changes in the nails such as discoloration, thickening, or separation from the nail bed. However, brittle, concave nails with a spoon-like appearance are not typical findings of candida infections. Therefore, while recent candida infection may affect the nails, it is less likely to explain the specific appearance observed in this case.
