What is an early sign of hypocalcemia that a nurse should monitor for?

Tingling in the fingers is a classic early sign of hypocalcemia, which refers to low levels of calcium in the blood. This symptom, known as paresthesia, is often among the first manifestations experienced by individuals with hypocalcemia. The tingling occurs due to increased excitability of the nerves and muscles as a result of calcium's crucial role in neuromuscular function. When calcium levels drop, it can lead to the nervous system becoming overly sensitive, causing such tingling sensations.

Other symptoms of hypocalcemia can develop as the condition worsens, but the presence of tingling is a key early indicator that nurses should be vigilant about monitoring. It serves as a warning sign that the patient's calcium levels may need to be assessed and potentially treated to avert further complications.
