Which subjective data most indicates a possible immune deficiency in a client?

The statement indicating "Just as I get over a virus, it seems that I get another" most strongly suggests a potential immune deficiency. This sentiment reflects a pattern of recurring infections, which is a hallmark of immune dysfunction. When the immune system is not functioning optimally, the body is less able to fend off infections, leading to frequent episodes of illness.

Clients experiencing immune deficiency often report repeated infections, and the inability to fully recover between illnesses can indicate that the immune system is compromised. This frequent cycle of illness could be due to a variety of factors, such as an underlying condition or medication that affects immune function.

Other responses, such as having morning stuffiness or a sore throat often, may indicate allergies or a mild infection but do not specifically point to immune deficiency. Similarly, having a sore on the leg that doesn’t heal might suggest other issues, such as localized infection or circulatory problems, rather than a systemic immune deficit. Therefore, option C stands out as the most indicative of potential immune deficiency.
