What term refers to the condition of neck stiffness?

• A. Nuchal rigidity
• B. Pallor
• C. Induration
• D. Fluctuance

Answer: (A)

Nuchal rigidity refers specifically to the stiffness and resistance to flexion observed in the neck. This condition is often associated with meningitis or other infections that irritate the meninges, the protective membranes covering the brain and spinal cord. The term "nuchal" pertains to the nape or back of the neck, while "rigidity" describes the inability to flex the neck due to muscle tightness or spasm.

The other terms are not related to neck stiffness. Pallor describes an unhealthy pale appearance, typically due to loss of blood flow, anemia, or other medical conditions. Induration refers to the process of becoming firm or hard, usually in the context of tissue, often related to inflammation or chronic conditions. Fluctuance indicates a specific type of swelling that feels soft or yielding, which may suggest the presence of fluid in a subcutaneous space, rather than stiffness. Thus, nuchal rigidity is the appropriate term for a condition involving neck stiffness.
