The medical term meaning abnormal condition of blue is
A.onychosis
B.acrocyanosis
C.cyanosis
D.onychomycosis
The correct answer and explanation is:
The correct answer is C. cyanosis.
Cyanosis refers to a bluish discoloration of the skin, mucous membranes, or extremities, which is due to insufficient oxygen in the blood. It typically occurs when the oxygen levels in the blood fall below normal, causing deoxygenated hemoglobin to give a blue tint to the skin. This condition can be a sign of various health issues, particularly respiratory or circulatory problems, such as lung diseases, heart failure, or severe hypoxia.
Cyanosis can be classified into two types:
- Central cyanosis: This type affects the central part of the body, including the lips, tongue, and face, and is typically caused by conditions affecting the heart or lungs, such as congenital heart defects, respiratory failure, or pulmonary diseases like chronic obstructive pulmonary disease (COPD).
- Peripheral cyanosis: This type occurs in the extremities, such as the hands and feet, and may be related to poor circulation, cold exposure, or vascular issues. It is often less severe and can sometimes be reversed by warming up the affected areas.
The other terms listed in the question are not related to blue discoloration:
- A. Onychosis refers to a disease or abnormal condition of the nails.
- B. Acrocyanosis refers to a bluish discoloration of the hands and feet, usually caused by poor circulation or vasoconstriction.
- D. Onychomycosis is a fungal infection of the nails, not related to cyanosis.
In summary, cyanosis is the term for the abnormal condition of blue, and it is an important clinical sign that often indicates serious underlying health conditions that require prompt medical attention.
