Which of the following indicates hypocalcemia?

• A. Calcium levels of 10.0 mg/dL
• B. Calcium levels of 9.5 mg/dL
• C. Calcium levels of 8.0 mg/dL
• D. Calcium levels of 11.0 mg/dL

Answer: (C)

Hypocalcemia is defined as having abnormally low levels of calcium in the blood. The normal range for calcium levels typically falls between 8.5 to 10.5 mg/dL. Therefore, a calcium level of 8.0 mg/dL falls below this normal range, indicating hypocalcemia. Low calcium levels may lead to various symptoms, including muscle spasms, tingling sensations, and cardiac issues, due to calcium's vital role in neuromuscular and cardiovascular function. Recognizing calcium levels that indicate a deficiency is crucial for proper diagnosis and treatment. The other provided levels are within normal limits or above, thus not indicating hypocalcemia.
