At what calcium level is considered a medical emergency?

A calcium level of 6.0 mg/dL is considered a medical emergency because it indicates severe hypocalcemia. Calcium is crucial for various physiological functions, including muscle contraction, nerve transmission, and blood coagulation. When levels drop significantly, it can lead to serious complications such as tetany (involuntary muscle contractions), seizures, cardiac arrhythmias, and even potential heart failure.

The body's normal calcium levels typically range from 8.5 to 10.5 mg/dL. A level as low as 6.0 signifies a critical deficiency that necessitates immediate medical intervention to prevent life-threatening complications. Recognizing these levels is crucial for nurses and healthcare providers in order to ensure timely treatment and monitoring of patients' calcium status.
