Final answer:
The nurse should expect hypoactive reflexes, fatigue, and anorexia in a client with a calcium level of 6.3.

When a person has a low calcium level, known as hypocalcemia, they may experience various symptoms. One of the symptoms the nurse should expect is hypoactive reflexes, which means that the person's reflexes will be slower and weaker than normal. Other symptoms of hypocalcemia include fatigue, feeling tired or lacking energy, and anorexia, a decreased appetite or loss of appetite.
