Which client color change indicates risk for heart disease?

• A. Client 4 Yellow orange color
• B. Client 1 Red color
• C. Client 3 Pallor color
• D. Client 2 Bluish

Answer: (D)

Cyanosis, the bluish discoloration of lips, tongue, or nail beds, signals insufficient oxygenation or poor perfusion, which can point to cardiovascular problems such as heart disease. When the blood is not adequately oxygenated—often due to heart or lung dysfunction—deoxygenated hemoglobin causes a blue tint observable in central areas like the lips and mucous membranes. This makes bluish color a more direct indicator of heart-related risk than other color changes. Yellow-orange can indicate jaundice, red can result from flushing or inflammation, and pallor suggests anemia or reduced perfusion but does not specifically flag heart disease risk in the same protective, diagnostic way.
