5 True/False Questions
SxS of Hypomagnesemia → CNS excitability, hyperactive deep tendon reflexes, painful parasthesias (numbness or prickly, stinging, or burning feeling), tetany (intermittent muscle spasms), cardiac dysrhythmias, confusion, constipation, or abdominal distention.
Tx of Hyperphosphatemia → Management of hypocalcemia and restrict foods high in P+.
Hematocrit Range Hct → 2.5-4.5 mEq/L
Most Common Cause of Hypomagnesemia → Mg+ deficit, diuretics, chronic alcoholism, or malnutrition.
Hypermagnesium → Magnesium deficiency or total serum Mg+ level of less than 1.3 mEq/L.
