Which subjective data most strongly indicates an immune deficiency in a client?

The statement that indicates an immune deficiency most strongly is the one expressing the recurring cycle of illness: "Just as I get over a virus, it seems that I get another." This subjective data reflects a pattern of frequent illnesses, which can suggest that the body's immune system is not functioning effectively.

In individuals with an adequate immune response, the body is typically able to recover from infections and viruses, building immunity against them. If someone experiences repeated infections in a short timeframe, it is a sign that their immune system may be compromised or not responding properly to threats. This pattern aligns closely with clinical indicators of immune deficiency, where the body struggles to fend off infections or develop immunity adequately.

The other options, while they may indicate some form of health issue, do not specifically point to immune deficiencies. Difficulty sleeping could suggest stress or other health problems, persistent headaches may be related to various conditions or lifestyle factors, and stomach pain after eating might indicate digestive issues or food intolerances rather than an immune response.
