Question

If central cyanosis is caused by a cardiac defect, which of the following would be considered a category?

A. The one with increased renal blood flow.
B. The one with a decreases liver blood flow.
C. The one with a decreased pulmonary blood flow.
D. The one with a decreases in pulmonary function.

Answer 1

In a cardiac defect causing central cyanosis, a decreased pulmonary blood flow would be considered a category.

Step-by-step explanation:

In the case of severe septal defects, such as tetralogy of Fallot or patent foramen ovale, a cardiac defect can cause central cyanosis, which is a blue or purple coloration of the skin due to insufficient supply of oxygenated blood. Among the given options, the one with a decreased pulmonary blood flow would be considered a category associated with a cardiac defect causing central cyanosis. This is because a decrease in pulmonary blood flow can result in reduced oxygenation of the blood, leading to cyanosis.
