Systemic signs and symptoms are best described as:

• A. Manifestations that affect the entire body, such as fever, malaise, and systemic lymphadenopathy.
• B. Local redness and swelling.
• C. Symptoms only in the respiratory system.
• D. Signs observed only in blood tests.

Answer: (B)

Systemic signs and symptoms reflect a body-wide response, not just something happening in one spot. Fever and malaise are classic examples because they indicate the whole body is involved—cytokines raise the body's temperature set point, and people feel generally unwell across systems. Systemic lymphadenopathy shows that the immune response is widespread, not confined to a single local area. In contrast, local redness and swelling are confined to a specific location, signaling a localized inflammatory process. Symptoms limited to the respiratory system point to involvement of that particular tract rather than the whole body. Signs seen only in blood tests are laboratory findings that may accompany illness but do not by themselves describe systemic, whole-body manifestations. So systemic signs and symptoms are best described as manifestations that affect the entire body, such as fever, malaise, and systemic lymphadenopathy.
