Hypocalcemia s/s typically present as:

• A. Everything high
• B. Everything low
• C. Heart rate decreased
• D. Improved reflexes

Answer: (A)

Low calcium increases neuromuscular excitability. Calcium normally stabilizes cell membranes, so when calcium is low, nerves and muscles fire more easily. That leads to tingling around the mouth and in the fingers, muscle cramps and tetany, and signs like Chvostek and Trousseau. Seizures can occur with severe hypocalcemia. Because the nervous system is more irritable, reflexes tend to be hyperactive rather than decreased or “improved.” Cardiac effects can include a prolonged QT interval, raising the risk of arrhythmias.

So the best pick is the one implying heightened overall activity or excitability. The other options don’t fit because they suggest the opposite state or lack the typical hyperreflexia seen with low calcium.
