Which parameter has a normal female range of 0.5-1.1?

Explanation:
Lab values often have sex-specific reference ranges, and creatinine in adults is typically given as a small range that accounts for differences in muscle mass. For females, a common normal range is about 0.5 to 1.1 mg/dL. Creatinine is a waste product from muscle metabolism that the kidneys filter, so its level reflects kidney function and, to an extent, muscle mass. The other parameters listed have different usual normal ranges: sodium is about 135–145 mEq/L, potassium about 3.5–5.0 mEq/L, and calcium roughly 8.5–10.5 mg/dL. Because 0.5–1.1 mg/dL aligns with creatinine in females, that option fits the given normal female range.
