A client with a malabsorption syndrome has a low serum calcium level. The practical nurse should monitor the client for which problem?

A. Bruising: Bruising is typically associated with platelet disorders or vitamin K deficiency, not directly with low calcium levels. While it should be monitored, it is not a primary concern for hypocalcemia. B. Pallor: Pallor usually indicates anemia or reduced perfusion. Low serum calcium does not directly cause pallor, so it is not the most relevant finding to monitor in this case. C. Jaundice: Jaundice reflects elevated bilirubin levels and liver dysfunction. It is unrelated to calcium deficiency and does not need to be a primary focus of monitoring in this client. D. Tetany: Hypocalcemia increases neuromuscular excitability, which can lead to tetany, characterized by muscle spasms, cramping, and positive Chvostek or Trousseau signs. Monitoring for tetany is essential for clients with low serum calcium to prevent complications.
